Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of PresentationThe accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).
Reclassifications	Reclassifications Certain comparative amounts for prior year have been reclassified to conform to current year presentations. Such reclassifications did not affect net income or retained earnings.
Use of Estimates	Use of Estimates Management is required to make certain estimates and assumptions in order to prepare financial statements in conformity with GAAP. Such estimates and assumptions affect the reported financial statements. The Company’s most significant estimates relate to net revenues, allowance for doubtful accounts, fair value measurements, goodwill and long-lived asset valuations and impairment assessments, inventory valuations, income tax valuations, stock-based compensation and royalty obligations, among others. Management bases estimates on historical experience and on assumptions that management believes are reasonable. The Company’s actual results could differ materially from those estimates. Additionally, the full impact of the COVID-19 outbreak is unknown and cannot be reasonably estimated. However, where possible, management has made appropriate accounting estimates with respect to certain accounting matters, which include the fair value of royalty obligations, allowance for doubtful accounts, inventory valuation and impairment assessments of goodwill and other long-lived assets, based on the facts and circumstances available as of the reporting date. The Company’s future assessment of the magnitude and duration of the COVID-19 outbreak, as well as other factors, could result in material impacts to the Company’s financial statements in future reporting periods.
Risks and Uncertainties and Concentration of Credit Risk	Risks and Uncertainties In 2013, Evolus and Daewoong Pharmaceutical Co. Ltd. (“Daewoong”) entered into an agreement (the “Daewoong Agreement”), pursuant to which the Company received an exclusive distribution license to Jeuveau® from Daewoong for aesthetic indications in the United States, European Union, United Kingdom, members of the European Economic Area, Switzerland, Canada, Australia, Russia, certain members of the Commonwealth of Independent States, and South Africa, as well as co-exclusive distribution rights with Daewoong in Japan. Jeuveau® is manufactured by Daewoong in a facility in South Korea. The Company also has the option to negotiate first with Daewoong to secure a distribution license for any product that Daewoong directly or indirectly develops or commercializes that is classified as an injectable botulinum toxin (other than Jeuveau®) in a territory covered by the Daewoong Agreement. The Company relies on Daewoong, its exclusive and sole supplier, to manufacture Jeuveau®. Any termination or loss of significant rights, including exclusivity, under the Daewoong Agreement would materially and adversely affect the Company’s commercialization of Jeuveau®. See Note 9. Commitments and Contingencies and Note 11. Medytox/Allergan Settlement Agreements and Daewoong Arrangement for additional information. The Company commercially launched Jeuveau® in the United States in May 2019 and in Canada through its distribution partner in October 2019 and, as such, has a limited history of sales. If any previously granted approval is retracted or the Company is denied approval or approval is delayed by any other regulators, it may have a material adverse impact on the Company’s business and its financial statements. The Company is also subject to risks common to companies in the pharmaceutical industry including, but not limited to, dependency on the commercial success of Jeuveau®, the Company’s sole commercial product, significant competition within the medical aesthetics industry, its ability to maintain regulatory approval of Jeuveau®, third party litigation and challenges to its intellectual property, uncertainty of broad adoption of its product by physicians and patients, its ability to in-license, acquire or develop additional product candidates and to obtain the necessary approvals for those product candidates, and the need to scale manufacturing capabilities over time. The COVID-19 outbreak and restrictions intended to slow the spread of COVID-19, including quarantines, government-mandated actions, stay-at-home orders and other restrictions, have adversely affected the Company’s business in a number of ways, which have resulted, and may continue to result, in a period of business disruption and in reduced sales and operations. In addition, any disruption and volatility in the global capital markets may increase the Company’s cost of capital and adversely affect its ability to access financing when and on terms that the Company desires. Any of these events could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows. Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents, short-term investments and accounts receivable. Substantially all of the Company’s cash is held by financial institutions that management believes are of high credit quality. Such deposits may, at times, exceed federally insured limits. To date, the Company has not experienced any losses associated with this credit risk and continues to believe that this exposure is not significant. The Company invests its excess cash, in line with its investment policy, primarily in money market funds and debt instruments of U.S. government agencies. The Company’s accounts receivable is derived from customers located principally in the United States. Concentrations of credit risk with respect to trade receivables are limited due to the Company’s credit evaluation process. The Company does not typically require collateral from its customers. Credit losses historically have not been material. The Company continuously monitors customer payments and maintains an allowance for doubtful accounts based on its assessment of various factors including historical experience, age of the receivable balances, and other current economic conditions or other factors that may affect customers’ ability to pay.
Segment Reporting	Segment Reporting Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker. The Company has determined that it operates in a single operating and reportable segment. The Company’s chief operating decision maker is its Chief Executive Officer who manages operations and reviews the financial information as a single operating segment for purposes of allocating resources and evaluating its financial performance.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid investments with remaining maturities at purchase of three months or less that can be liquidated without prior notice or penalty. Cash and cash equivalents may include deposits, money market funds and debt securities. Amounts receivable from credit card issuers are typically converted to cash within two to four days of the original sales transaction and are considered to be cash equivalents.
Short-Term Investments	Short-Term Investments Short-term investments consist of available-for-sale U.S. Treasury securities with original maturities greater than three months and remaining maturities of less than twelve months. These investments are recorded at fair value based on quoted prices in active markets, with unrealized gains and losses reported in other comprehensive gain (loss) in the Company’s statements of operations and comprehensive loss. Purchase premiums and discounts are recognized in interest expense using the effective interest method over the terms of the securities. Realized gains and losses and declines in fair value that are deemed to be other than temporary are reflected in the statements of operations and comprehensive loss using the specific-identification method. The Company periodically reviews all available-for-sale securities for other than temporary declines in fair value below the cost basis whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company also evaluates whether it has plans or is required to sell short-term investments before recovery of their amortized cost bases. To date, the Company has not identified any other than temporary declines in fair value of its short-term investments.
Inventories	Inventories Inventories consist of finished goods held for sale and distribution. Cost is determined based on the estimated amount payable to the Company’s supplier after accounting for any reimbursement receivable pursuant to the Daewoong Settlement Agreement (as such term is defined, and such agreement is discussed, in Note 11. Medytox/Allergan Settlement Agreements and Daewoong Arrangement), using the first-in, first-out method with prioritization of the items with the earliest expiration dates. Inventory valuation reserves are established based on a number of factors including, but not limited to, finished goods not meeting product specifications, product excess and obsolescence, or application of the lower of cost or net realizable value concepts. The determination of events requiring the establishment of inventory valuation reserves, together with the calculation of the amount of such reserves may require judgment. No material inventory valuation reserves have been recorded for the periods presented. Adverse changes in assumptions utilized in the Company’s inventory reserve calculations could result in an increase to its inventory valuation reserves. Product cost of sales, excluding amortization of intangible assets, consisted of the inventory cost, and, for periods on or after December 16, 2020, included certain royalties on the sale of Jeuveau® payable to Medytox and Allergan pursuant to the Medytox/Allergan Settlement Agreements (as such term is defined in Note 11. Medytox/Allergan Settlement Agreements and Daewoong Arrangement), as partially offset by reimbursement receivable from Daewoong pursuant to the Daewoong Settlement Agreement with respect to such royalties.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in an orderly transaction between market participants in a principal market on the measurement date. The fair value hierarchy defines a three-tiered valuation hierarchy for disclosure of fair value measurement is classified and disclosed by the Company in one of the three categories as follows: •Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; •Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in active markets; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly, or can be corroborated by observable market data for substantially the full term of the asset or liability; and •Level 3—Prices or valuation techniques that require inputs that are unobservable that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
Property and Equipment	Property and EquipmentProperty and equipment are stated at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of approximately five years. Leasehold improvements are amortized over the shorter of the estimated useful lives of the improvements or the term of the related lease.
Goodwill	GoodwillGoodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired in a business combination. The Company reviews goodwill for impairment annually and whenever events or changes in circumstances indicate the carrying amount of goodwill may not be recoverable. The Company performs an annual qualitative assessment of its goodwill in the fourth quarter of each calendar year to determine if any events or circumstances exist, such as an adverse change in business climate or a decline in the overall industry demand, that would indicate that it would more likely than not reduce the fair value of a reporting unit below its carrying amount, including goodwill. If events or circumstances do not indicate that the fair value of a reporting unit is below its carrying amount, then goodwill is not considered to be impaired and no further testing is required. If further testing is required, the Company performs a two-step process. The first step involves comparing the fair value of the Company’s reporting unit to its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step of the test is performed by comparing the carrying value of the goodwill in the reporting unit to its implied fair value. An impairment charge is recognized for the excess of the carrying value of goodwill over its implied fair value. For the purpose of impairment testing, the Company has determined that it has one reporting unit.
Intangible Assets	Intangible Assets Upon FDA approval of Jeuveau® in February 2019, the in process research and development (“IPR&D”) related to Jeuveau® was evaluated as completed and reclassified to a definite-lived distribution right intangible asset, which is amortized over the period the asset is expected to contribute to the future cash flows of the Company. The Company determined the pattern of this intangible asset’s future cash flows could not be readily determined with a high level of precision. As a result, the distribution right intangible asset is being amortized on a straight-line basis over the estimated useful life of 20 years. The Company capitalizes certain internal-use software costs associated with the development of its mobile and web-based customer platforms. These costs include personnel expenses and external costs that are directly associated with the software projects. These costs are included as intangible assets in the accompanying balance sheets. The capitalized internal-use software costs are amortized on a straight-line basis over the estimated useful life of two years upon being placed in service. The Company reviews long-term and identifiable definite-lived intangible assets or asset groups for impairment when events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. If the sum of the expected future undiscounted cash flows is less than the carrying amount of the asset or an asset group, further impairment analysis is performed. An impairment loss is measured as the amount by which the carrying amount of the asset or asset groups exceeds the fair value for assets to be held and used or fair value less cost to sell for assets to be disposed of. The Company also reviews the useful lives of its assets periodically to determine whether events and circumstances warrant a revision to the remaining useful life. Changes in the useful life are adjusted prospectively by revising the remaining period over which the asset is amortized. There was no material impairment of long-lived assets for any periods presented
Leases	Leases In accordance with Accounting Standards Codification 842, Leases (“ASC 842”), at the inception of a contractual arrangement, the Company determines whether the contract contains a lease by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration over a period of time. If both criteria are met, upon lease commencement, the Company records a lease liability which represents the Company’s obligation to make lease payments arising from the lease, and a corresponding right-of-use (“ROU”) asset which represents the Company’s right to use an underlying asset during the lease term. Operating lease assets and liabilities are included in ROU assets, current portion of operating lease liabilities and noncurrent operating lease liabilities in the accompanying balance sheets. Operating lease ROU assets and lease liabilities are initially recognized based on the present value of the future minimum lease payments over the lease term at commencement date calculated using the Company’s incremental borrowing rate applicable to the underlying asset unless the implicit rate is readily determinable. Operating lease ROU assets also include any lease payments made at or before lease commencement and exclude any lease incentives received, if any. The Company determines the lease term as the noncancelable period of the lease and may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. The Company’s leases do not contain any residual value guarantees. Leases with a term of 12 months or less are not recognized on the balance sheets. For operating leases, the Company recognized rent expense on a straight-line basis over the lease term. There were no significant finance leases as of December 31, 2021.
Contingent Royalty Obligation Payable and Promissory Note Payable to the Evolus Founders	Contingent Royalty Obligation Payable to the Evolus Founders The Company determines the fair value of the contingent royalty obligation payable at each reporting period end based on Level 3 inputs using a discounted cash flows method. Changes in the fair value of the contingent royalty obligation payable are determined at each reporting period end and recorded in operating expenses in the accompanying statements of operations and comprehensive loss and as a liability in the accompanying balance sheets. Promissory Note Payable to the Evolus Founders On February 12, 2018, the Company recognized a promissory note payable at present value using a discount rate for similar rated debt securities. Discount amortization related to the promissory note is recorded in interest expense in the accompanying statements of operations and comprehensive loss with a corresponding increase to the liabilities in the accompanying balance sheets.
Long-term Debt	Long-term Debt Long-term debt represents the debt balance with Pharmakon as of December 31, 2021 and Oxford as of December 31, 2020 (see Note 6. Term Loans), net of debt issuance costs. Debt issuance costs represent legal, lender and consulting costs or fees associated with debt financing. Debt discounts and issuance costs are amortized into interest expense over the term of the debt.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when control of the promised goods or services is transferred to its customers, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for the goods or services. In order to achieve that core principle, a five-step approach is applied: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue allocated to each performance obligation when the Company satisfies the performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account for revenue recognition. General The Company generates product revenue from the sale of Jeuveau® in the United States and service revenue from the sale of Jeuveau® through a distribution partner in Canada. For product revenue, the Company recognizes revenue when control of the promised goods under a contract is transferred to a customer, in an amount that reflects the consideration the Company expects to receive in exchange for those goods as specified in the customer contract. The transfer of control occurs upon receipt of the goods by the customer since that is when the customer has obtained control of the goods’ economic benefits. The Company does not provide any service-type warranties and does not accept product returns except under limited circumstances such as damages in transit or ineffective product. The Company also excludes any amounts related to taxes assessed by governmental authorities from revenue measurement. Shipping and handling costs associated with outbound product freight are accounted for as fulfillment costs and are included in selling, general and administrative expenses in the accompanying statements of operations and comprehensive loss. For service revenue, the Company evaluated the arrangement with the distribution partner in Canada and determined that it acts as an agent in the distribution of Jeuveau® in Canada as it does not control the product before control is transferred to a customer. The indicators of which party exercises control include primary responsibility over performance obligations, inventory risk before the good or service is transferred and discretion in establishing the price. Accordingly, the Company records the sale as service revenue on a net basis. Revenue from services is recognized in the period the service is performed for the amount of consideration expected to be received. For the years ended December 31, 2021 and 2020, the Company recognized $702 and $738, respectively, of revenues related to international sales. Disaggregation of Revenue The Company’s disaggregation of revenue is consistent with its operating segment as disclosed above. Gross-to-Net Revenue Adjustments The Company provides customers with discounts, such as trade and volume discounts and prompt pay discounts, that are directly reflected in the invoice price. Revenues are recorded net of sales-related adjustments, wherever applicable, primarily for the volume based rebates, coupons, consumer loyalty programs and co-branded marketing programs. •Volume-based Rebates — Volume-based rebates are contractually offered to certain customers. The rebates payable to each customer are determined based on the contract and quarterly purchase volumes. •Coupons — The Company issued customers coupons redeemable into gift cards funded by the Company for the benefit of patients. The coupons were accounted for as variable consideration. The Company estimated coupon redemption rates based on historical data and future expectations. The coupons were accrued based on estimated redemption rates and the volume of products purchased and were recorded as a reduction to revenues on product delivery. All issued coupons expired on June 30, 2020. •Consumer Loyalty Program — In May 2020, the Company launched a consumer loyalty program, which allows participating customers to earn rewards for qualifying treatments to their patients (i.e. consumers) using Jeuveau® and redeem the rewards for Jeuveau® in the future at no additional cost. The loyalty program represents a customer option that provides a material right and, accordingly, is a performance obligation. At the time Jeuveau® product is sold to customers, the invoice price is allocated between the product sold and the estimated material right reward (“Reward”) that the customer might redeem in the future. The standalone selling price of the Reward is measured based on historical sales data, estimated average selling price of Jeuveau® at the time of redemption, expected customer and consumer participation rates in the loyalty program, and estimated number of qualifying treatments to be performed by customers. The portion of invoice price allocated to the Reward is initially recorded as deferred revenue. Subsequently, when customers redeem the Reward and the related product is delivered, the deferred revenue is recognized in net revenues at that time. •Co-Branded Marketing Programs — The Company offers eligible customers with a certain level of Jeuveau® purchases to receive advertising co-branded with the Company. The co-branded advertising represents a performance obligation. At the time Jeuveau® product is sold to customers, the invoice price is allocated between the product sold and the advertisement. The standalone selling price of the advertisement is measured based on the estimated market value of similar advertisement adjusted for the customer’s portion of the advertisement. The portion of invoice price allocated to the advertisement is initially recorded as deferred revenue. Subsequently, when the advertisement airs, the deferred revenue is recognized in net revenues at that time. Contract balances A contract with a customer states the terms of the sale, including the description, quantity and price of each product purchased. Amounts are recorded as accounts receivable when the Company’s right to consideration becomes unconditional. The Company does not have any significant financing components in customer contracts given the expected time between transfer of the promised products and the payment of the associated consideration is less than one year. As of December 31, 2021 and 2020, all amounts included in accounts receivable, net on the accompanying balance sheets are related to contracts with customers. The Company did not have any contract assets nor unbilled receivables as of December 31, 2021 or 2020. Sales commissions are included in selling, general and administrative expenses when incurred. Contract liabilities reflect estimated amounts that the Company is obligated to pay to customers or patients primarily under the rebate and coupon programs and deferred revenue associated with Rewards under the consumer loyalty program and co- branded marketing programs. The Company’s contract liabilities are included in accounts payable and accrued expenses in the accompanying balance sheets. As of December 31, 2021 and 2020, the accrued revenue contract liabilities, primarily related to volume-based rebates, consumer loyalty program, and co-branded media programs, were $7,934 and $3,081, respectively, which were recorded in accrued expenses in the accompanying balance sheets. For the years ended December 31, 2021 and 2020, provisions for rebate, coupon, consumer loyalty programs, and co-branded media programs were $16,139 and $16,896, respectively, which were offset by related payments, redemptions and adjustments of $11,286 and $15,524, respectively. During the years ended December 31, 2021 and 2020, the Company recognized $2,802 and $0, respectively, of revenue related to amounts included in contract liabilities at the beginning of the period and did not recognize any revenue related to changes in transaction prices regarding its contracts with customers from previous periods. Collectability Accounts receivable are recorded at the invoiced amount and do not bear interest. At the time of contract inception or new customer account set-up, the Company performs a collectability assessment of the customer’s creditworthiness. The Company assesses the probability that the Company will collect the entitled consideration in exchange for the goods sold, by considering the customer’s ability and intention to pay when consideration is due. On a recurring basis, the Company estimates the amount of receivables considered uncollectable to reflect an allowance for doubtful accounts. The Company writes off accounts receivable balances when it is determined that there is no possibility of collection. As of December 31, 2021 and 2020, allowance for doubtful accounts was $2,385 and $2,118, respectively. For the years ended December 31, 2021 and 2020, provision for bad debts was $589 and $2,066, respectively, and the write-off amount was $322 and $335, respectively. Practical Expedients The Company expenses sales commissions when incurred as the amortization period is one year or less. These costs are recorded within selling, general and administrative expenses in the accompanying statements of operations and comprehensive loss. The Company does not adjust the amount of promised consideration for the effects of the time value of money for contracts in which the anticipated period between when the Company transfers the goods or services to the customer and when the customer pays within one year.
Research and Development Expenses	Research and Development Expenses Research and development costs are expensed as incurred. Research and development expenses include personnel-related costs, costs associated with pre-clinical and clinical development activities, costs associated with and costs for prototype products that are manufactured prior to market approval for that prototype product, internal and external costs associated with the Company’s regulatory compliance and quality assurance functions, including the costs of outside consultants and contractors that assist in the process of submitting and maintaining regulatory filings, and overhead costs, including allocated facility related expenses.
Stock-Based Compensation	Stock-Based Compensation The Company recognizes stock-based compensation expense for employees, consultants and members of the Board of Directors based on the fair value at the date of grant. The Company uses the Black-Scholes option pricing model to value stock option grants. The Black-Scholes option pricing model requires the input of subjective assumptions, including the expected volatility of the Company’s common stock, expected risk-free interest rate, and the option’s expected life. The fair value of the Company’s restricted stock units (“RSUs”) is based on the fair value on the grant date of the Company’s common stock. The Company also evaluates the impact of modifications made to the original terms of equity awards when they occur. The fair value of equity awards that are expected to vest is amortized on a straight-line basis over the requisite service period. Stock-based compensation expense is recognized net of actual forfeitures when they occur, as an increase to additional paid-in capital in the balance sheets and in the selling, general and administrative or research and development expenses in the statements of operations and comprehensive loss.
Advertising Costs	Advertising CostsAdvertising costs are expensed as incurred and primarily include costs related to social media ads and co-branded marketing programs. Advertising costs are included in selling, general and administrative expenses.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are determined on the basis of differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is recorded against deferred tax assets to reduce the net carrying value when it is more likely than not that some portion or all of a deferred tax asset will not be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, and ongoing prudent and feasible tax planning strategies in assessing the amount of the valuation allowance. When the Company establishes or reduces the valuation allowance against its deferred tax assets, its provision for income taxes will increase or decrease, respectively, in the period such determination is made. Additionally, the Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefit recognized in the financial statements for a particular tax position is based on the largest benefit that is more likely than not to be realized upon settlement. Accordingly, the Company establishes reserves for uncertain tax positions. The Company has not recognized interest or penalties in its statement of operations and comprehensive loss. The Company is required to file federal and state income tax returns in the United States and various other state jurisdictions. The preparation of these income tax returns requires the Company to interpret the applicable tax laws and regulations in effect in such jurisdictions, which could affect the amount of tax paid by the Company. An amount is accrued for the estimate of additional tax liability, including interest and penalties, for any uncertain tax positions taken or expected to be taken in an income tax return. The Company reviews and updates the accrual for uncertain tax positions as more definitive information becomes available. The Company’s income tax returns are based on calculations and assumptions that are subject to examination by the Internal Revenue Service and other tax authorities. In addition, the calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. While the Company believes it has appropriate support for the positions taken on its tax returns, the Company regularly assesses the potential outcomes of examinations by tax authorities in determining the adequacy of its provision for income taxes. The Company continually assesses the likelihood and amount of potential revisions and adjusts the income tax provision, income taxes payable and deferred taxes in the period in which the facts that give rise to a revision become known. The Company monitors changes to the tax laws in the states it conducts business and files corporate income tax returns. The Company does not expect that changes to state tax laws through December 31, 2021 to materially impact its financial statements.
Net Loss Per Share	Net Loss Per Share Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period including contingently issuable shares. Diluted earnings per share is based on the treasury stock method and includes the effect from potential issuance of ordinary shares, such as shares issuable pursuant to the exercise of stock options and the vesting of restricted stock units. The dilutive effect of stock options and restricted stock units is computed under the treasury stock method. The dilutive effect of the Daewoong Convertible Note is computed under the if-converted method. Potentially dilutive securities are excluded from the computations of diluted net loss per share if their effect would be antidilutive.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Pronouncements In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. FASB issued this update as part of its Simplification Initiative to improve areas of GAAP and reduce cost and complexity while maintaining usefulness. The main provisions remove certain exceptions including the exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. In addition, the amendments simplify income tax accounting in the areas such as income based franchise taxes, eliminating the requirements to allocate consolidated current and deferred tax expense in certain instances and a requirement that an entity reflects the effect of enacted changes in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. For public companies, the standard is effective for fiscal years beginning after December 15, 2020 and interim periods therein. The Company has adopted the guidance on the effective date of January 1, 2021. There are no material impacts to the financial statements as a result of this adoption. Recent Accounting Pronouncements Issued But Not Adopted In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The update simplifies the accounting for goodwill impairment by removing step two of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will be the amount by which a reporting unit’s carrying amount, including goodwill, exceeds its fair value. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. As amended by ASU No. 2019-10, the updated guidance is effective for the Company as a smaller reporting company beginning January 1, 2023. The standard requires prospective application. Early adoption is permitted. The Company does not expect adoption of this guidance will have a material impact on its financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which modifies the measurement and recognition of credit losses for most financial assets and certain other instruments. The new standard requires the use of forward-looking expected credit loss models based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount, which may result in earlier recognition of credit losses under the new standard. The new guidance also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. Subsequent to the issuance of ASU No. 2016-13, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. This ASU does not change the core principle of the guidance in ASU No. 2016-13, instead these amendments are intended to clarify and improve operability of certain topics included within the credit losses standard. The FASB also subsequently issued ASU No. 2019-04 which did not change the core principle of the guidance in ASU No. 2016-13 but clarified that expected recoveries of amounts previously written off and expected to be written off should be included in the valuation account and should not exceed amounts previously written off and expected to be written off. As amended by ASU No. 2019-10, the updated guidance is effective for the Company as a smaller reporting company beginning January 1, 2023. The Company is in the process of determining the effects the adoption will have on its financial statements and reviewing credit loss models to assess the impact of the adoption of the standard on the financial statements. Based on initial assessments, the Company believes that while adoption will modify the way it analyzes financial instruments, it does not expect adoption of this guidance will have a material impact to its financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting and in January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope (“ASU 2021-01”). Both ASU No. 2020-04 and ASU No. 2021-01 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. ASU No. 2020-04 and ASU No. 2021-01 are effective upon issuance for contract modifications and hedging relationships, and the Company is allowed to elect to apply the amendments prospectively through December 31, 2022. The Company does not expect adoption of this guidance will have a material impact on its financial statements. In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. This update will increase transparency of government assistance received by most business entities by requiring the disclosure of: (1) the types of transactions; (2) the accounting for the transactions; and, (3) the effect of the transactions on a business entity’s financial statements. ASU No. 2021-10 is effective for financial statements issued for annual periods beginning after December 15, 2021, with early application permitted. The Company does not expect adoption of this guidance will have a material impact on its financial statements. Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants, and the SEC did not, or are not believed by management to, have a material impact on the Company’s present or future financial position, results of operations or cash flows.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2021

Basis of PresentationThe accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

Reclassifications

Certain comparative amounts for prior year have been reclassified to conform to current year presentations. Such reclassifications did not affect net income or retained earnings.

Use of Estimates

Management is required to make certain estimates and assumptions in order to prepare financial statements in conformity with GAAP. Such estimates and assumptions affect the reported financial statements. The Company’s most significant estimates relate to net revenues, allowance for doubtful accounts, fair value measurements, goodwill and long-lived asset valuations and impairment assessments, inventory valuations, income tax valuations, stock-based compensation and royalty obligations, among others. Management bases estimates on historical experience and on assumptions that management believes are reasonable. The Company’s actual results could differ materially from those estimates.

Additionally, the full impact of the COVID-19 outbreak is unknown and cannot be reasonably estimated. However, where possible, management has made appropriate accounting estimates with respect to certain accounting matters, which include the fair value of royalty obligations, allowance for doubtful accounts, inventory valuation and impairment assessments of goodwill and other long-lived assets, based on the facts and circumstances available as of the reporting date. The Company’s future assessment of the magnitude and duration of the COVID-19 outbreak, as well as other factors, could result in material impacts to the Company’s financial statements in future reporting periods.

Risks and Uncertainties and Concentration of Credit Risk

Risks and Uncertainties

In 2013, Evolus and Daewoong Pharmaceutical Co. Ltd. (“Daewoong”) entered into an agreement (the “Daewoong Agreement”), pursuant to which the Company received an exclusive distribution license to Jeuveau® from Daewoong for aesthetic indications in the United States, European Union, United Kingdom, members of the European Economic Area, Switzerland, Canada, Australia, Russia, certain members of the Commonwealth of Independent States, and South Africa, as well as co-exclusive distribution rights with Daewoong in Japan. Jeuveau® is manufactured by Daewoong in a facility in South Korea. The Company also has the option to negotiate first with Daewoong to secure a distribution license for any product that Daewoong directly or indirectly develops or commercializes that is classified as an injectable botulinum toxin (other than Jeuveau®) in a territory covered by the Daewoong Agreement. The Company relies on Daewoong, its exclusive and sole supplier, to manufacture Jeuveau®. Any termination or loss of significant rights, including exclusivity, under the Daewoong Agreement would materially and adversely affect the Company’s commercialization of Jeuveau®. See Note 9. Commitments and Contingencies and Note 11. Medytox/Allergan Settlement Agreements and Daewoong Arrangement for additional information.

The Company commercially launched Jeuveau® in the United States in May 2019 and in Canada through its distribution partner in October 2019 and, as such, has a limited history of sales. If any previously granted approval is retracted or the Company is denied approval or approval is delayed by any other regulators, it may have a material adverse impact on the Company’s business and its financial statements.

The Company is also subject to risks common to companies in the pharmaceutical industry including, but not limited to, dependency on the commercial success of Jeuveau®, the Company’s sole commercial product, significant competition within the medical aesthetics industry, its ability to maintain regulatory approval of Jeuveau®, third party litigation and challenges to its intellectual property, uncertainty of broad adoption of its product by physicians and patients, its ability to in-license, acquire or develop additional product candidates and to obtain the necessary approvals for those product candidates, and the need to scale manufacturing capabilities over time.

The COVID-19 outbreak and restrictions intended to slow the spread of COVID-19, including quarantines, government-mandated actions, stay-at-home orders and other restrictions, have adversely affected the Company’s business in a number of ways, which have resulted, and may continue to result, in a period of business disruption and in reduced sales and operations. In addition, any disruption and volatility in the global capital markets may increase the Company’s cost of capital and adversely affect its ability to access financing when and on terms that the Company desires. Any of these events could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents, short-term investments and accounts receivable. Substantially all of the Company’s cash is held by financial institutions that management believes are of high credit quality. Such deposits may, at times, exceed federally insured limits. To date, the Company has not experienced any losses associated with this credit risk and continues to believe that this exposure is not significant. The Company invests its excess cash, in line with its investment policy, primarily in money market funds and debt instruments of U.S. government agencies.

The Company’s accounts receivable is derived from customers located principally in the United States. Concentrations of credit risk with respect to trade receivables are limited due to the Company’s credit evaluation process. The Company does not typically require collateral from its customers. Credit losses historically have not been material. The Company continuously monitors customer payments and maintains an allowance for doubtful accounts based on its assessment of various factors including historical experience, age of the receivable balances, and other current economic conditions or other factors that may affect customers’ ability to pay.

Segment Reporting

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker. The Company has determined that it operates in a single operating and reportable segment. The Company’s chief operating decision maker is its Chief Executive Officer who manages operations and reviews the financial information as a single operating segment for purposes of allocating resources and evaluating its financial performance.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and highly liquid investments with remaining maturities at purchase of three months or less that can be liquidated without prior notice or penalty. Cash and cash equivalents may include deposits, money market funds and debt securities. Amounts receivable from credit card issuers are typically converted to cash within two to four days of the original sales transaction and are considered to be cash equivalents.

Short-Term Investments

Short-term investments consist of available-for-sale U.S. Treasury securities with original maturities greater than three months and remaining maturities of less than twelve months. These investments are recorded at fair value based on quoted prices in active markets, with unrealized gains and losses reported in other comprehensive gain (loss) in the Company’s statements of operations and comprehensive loss. Purchase premiums and discounts are recognized in interest expense using the effective interest method over the terms of the securities. Realized gains and losses and declines in fair value that are deemed to be other than temporary are reflected in the statements of operations and comprehensive loss using the specific-identification method.

The Company periodically reviews all available-for-sale securities for other than temporary declines in fair value below the cost basis whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company also evaluates whether it has plans or is required to sell short-term investments before recovery of their amortized cost bases. To date, the Company has not identified any other than temporary declines in fair value of its short-term investments.

Inventories

Inventories consist of finished goods held for sale and distribution. Cost is determined based on the estimated amount payable to the Company’s supplier after accounting for any reimbursement receivable pursuant to the Daewoong Settlement Agreement (as such term is defined, and such agreement is discussed, in Note 11. Medytox/Allergan Settlement Agreements and Daewoong Arrangement), using the first-in, first-out method with prioritization of the items with the earliest expiration dates. Inventory valuation reserves are established based on a number of factors including, but not limited to, finished goods not meeting product specifications, product excess and obsolescence, or application of the lower of cost or net realizable value concepts. The determination of events requiring the establishment of inventory valuation reserves, together with the calculation of the amount of such reserves may require judgment. No material inventory valuation reserves have been recorded for the periods presented. Adverse changes in assumptions utilized in the Company’s inventory reserve calculations could result in an increase to its inventory valuation reserves.

Product cost of sales, excluding amortization of intangible assets, consisted of the inventory cost, and, for periods on or after December 16, 2020, included certain royalties on the sale of Jeuveau® payable to Medytox and Allergan pursuant to the Medytox/Allergan Settlement Agreements (as such term is defined in Note 11. Medytox/Allergan Settlement Agreements and Daewoong Arrangement), as partially offset by reimbursement receivable from Daewoong pursuant to the Daewoong Settlement Agreement with respect to such royalties.

Fair Value of Financial Instruments

Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in an orderly transaction between market participants in a principal market on the measurement date.

The fair value hierarchy defines a three-tiered valuation hierarchy for disclosure of fair value measurement is classified and disclosed by the Company in one of the three categories as follows:

•Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

•Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in active markets; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly, or can be corroborated by observable market data for substantially the full term of the asset or liability; and

•Level 3—Prices or valuation techniques that require inputs that are unobservable that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Property and Equipment

Property and EquipmentProperty and equipment are stated at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of approximately five years. Leasehold improvements are amortized over the shorter of the estimated useful lives of the improvements or the term of the related lease.

Goodwill

GoodwillGoodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired in a business combination. The Company reviews goodwill for impairment annually and whenever events or changes in circumstances indicate the carrying amount of goodwill may not be recoverable. The Company performs an annual qualitative assessment of its goodwill in the fourth quarter of each calendar year to determine if any events or circumstances exist, such as an adverse change in business climate or a decline in the overall industry demand, that would indicate that it would more likely than not reduce the fair value of a reporting unit below its carrying amount, including goodwill. If events or circumstances do not indicate that the fair value of a reporting unit is below its carrying amount, then goodwill is not considered to be impaired and no further testing is required. If further testing is required, the Company performs a two-step process. The first step involves comparing the fair value of the Company’s reporting unit to its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step of the test is performed by comparing the carrying value of the goodwill in the reporting unit to its implied fair value. An impairment charge is recognized for the excess of the carrying value of goodwill over its implied fair value. For the purpose of impairment testing, the Company has determined that it has one reporting unit.

Intangible Assets

Upon FDA approval of Jeuveau® in February 2019, the in process research and development (“IPR&D”) related to Jeuveau® was evaluated as completed and reclassified to a definite-lived distribution right intangible asset, which is amortized over the period the asset is expected to contribute to the future cash flows of the Company. The Company determined the pattern of this intangible asset’s future cash flows could not be readily determined with a high level of precision. As a result, the distribution right intangible asset is being amortized on a straight-line basis over the estimated useful life of 20 years.

The Company capitalizes certain internal-use software costs associated with the development of its mobile and web-based customer platforms. These costs include personnel expenses and external costs that are directly associated with the software projects. These costs are included as intangible assets in the accompanying balance sheets. The capitalized internal-use software costs are amortized on a straight-line basis over the estimated useful life of two years upon being placed in service.

The Company reviews long-term and identifiable definite-lived intangible assets or asset groups for impairment when events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. If the sum of the expected future undiscounted cash flows is less than the carrying amount of the asset or an asset group, further impairment analysis is performed. An impairment loss is measured as the amount by which the carrying amount of the asset or asset groups exceeds the fair value for assets to be held and used or fair value less cost to sell for assets to be disposed of. The Company also reviews the useful lives of its assets periodically to determine whether events and circumstances warrant a revision to the remaining useful life. Changes in the useful life are adjusted prospectively by revising the remaining period over which the asset is amortized. There was no material impairment of long-lived assets for any periods presented

Leases

In accordance with Accounting Standards Codification 842, Leases (“ASC 842”), at the inception of a contractual arrangement, the Company determines whether the contract contains a lease by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration over a period of time. If both criteria are met, upon lease commencement, the Company records a lease liability which represents the Company’s obligation to make lease payments arising from the lease, and a corresponding right-of-use (“ROU”) asset which represents the Company’s right to use an underlying asset during the lease term. Operating lease assets and liabilities are included in ROU assets, current portion of operating lease liabilities and noncurrent operating lease liabilities in the accompanying balance sheets.

Operating lease ROU assets and lease liabilities are initially recognized based on the present value of the future minimum lease payments over the lease term at commencement date calculated using the Company’s incremental borrowing rate applicable to the underlying asset unless the implicit rate is readily determinable. Operating lease ROU assets also include any lease payments made at or before lease commencement and exclude any lease incentives received, if any. The Company determines the lease term as the noncancelable period of the lease and may include options to extend or terminate the lease

when it is reasonably certain that the Company will exercise such options. The Company’s leases do not contain any residual value guarantees. Leases with a term of 12 months or less are not recognized on the balance sheets. For operating leases, the Company recognized rent expense on a straight-line basis over the lease term. There were no significant finance leases as of December 31, 2021.

Contingent Royalty Obligation Payable and Promissory Note Payable to the Evolus Founders

Contingent Royalty Obligation Payable to the Evolus Founders

The Company determines the fair value of the contingent royalty obligation payable at each reporting period end based on Level 3 inputs using a discounted cash flows method. Changes in the fair value of the contingent royalty obligation payable are determined at each reporting period end and recorded in operating expenses in the accompanying statements of operations and comprehensive loss and as a liability in the accompanying balance sheets.

Promissory Note Payable to the Evolus Founders

On February 12, 2018, the Company recognized a promissory note payable at present value using a discount rate for similar rated debt securities. Discount amortization related to the promissory note is recorded in interest expense in the accompanying statements of operations and comprehensive loss with a corresponding increase to the liabilities in the accompanying balance sheets.

Long-term Debt

Long-term debt represents the debt balance with Pharmakon as of December 31, 2021 and Oxford as of December 31, 2020 (see Note 6. Term Loans), net of debt issuance costs. Debt issuance costs represent legal, lender and consulting costs or fees associated with debt financing. Debt discounts and issuance costs are amortized into interest expense over the term of the debt.

Revenue Recognition

The Company recognizes revenue when control of the promised goods or services is transferred to its customers, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for the goods or services. In order to achieve that core principle, a five-step approach is applied: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue allocated to each performance obligation when the Company satisfies the performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account for revenue recognition.

General

The Company generates product revenue from the sale of Jeuveau® in the United States and service revenue from the sale of Jeuveau® through a distribution partner in Canada.

For product revenue, the Company recognizes revenue when control of the promised goods under a contract is transferred to a customer, in an amount that reflects the consideration the Company expects to receive in exchange for those goods as specified in the customer contract. The transfer of control occurs upon receipt of the goods by the customer since that is when the customer has obtained control of the goods’ economic benefits. The Company does not provide any service-type warranties and does not accept product returns except under limited circumstances such as damages in transit or ineffective product. The Company also excludes any amounts related to taxes assessed by governmental authorities from revenue measurement. Shipping and handling costs associated with outbound product freight are accounted for as fulfillment costs and are included in selling, general and administrative expenses in the accompanying statements of operations and comprehensive loss.

For service revenue, the Company evaluated the arrangement with the distribution partner in Canada and determined that it acts as an agent in the distribution of Jeuveau® in Canada as it does not control the product before control is transferred to a customer. The indicators of which party exercises control include primary responsibility over performance obligations, inventory risk before the good or service is transferred and discretion in establishing the price. Accordingly, the Company records the sale as service revenue on a net basis. Revenue from services is recognized in the period the service is performed

for the amount of consideration expected to be received. For the years ended December 31, 2021 and 2020, the Company recognized $702 and $738, respectively, of revenues related to international sales.

Disaggregation of Revenue

The Company’s disaggregation of revenue is consistent with its operating segment as disclosed above.

Gross-to-Net Revenue Adjustments

The Company provides customers with discounts, such as trade and volume discounts and prompt pay discounts, that are directly reflected in the invoice price. Revenues are recorded net of sales-related adjustments, wherever applicable, primarily for the volume based rebates, coupons, consumer loyalty programs and co-branded marketing programs.

•Volume-based Rebates — Volume-based rebates are contractually offered to certain customers. The rebates payable to each customer are determined based on the contract and quarterly purchase volumes.

•Coupons — The Company issued customers coupons redeemable into gift cards funded by the Company for the benefit of patients. The coupons were accounted for as variable consideration. The Company estimated coupon redemption rates based on historical data and future expectations. The coupons were accrued based on estimated redemption rates and the volume of products purchased and were recorded as a reduction to revenues on product delivery. All issued coupons expired on June 30, 2020.

•Consumer Loyalty Program — In May 2020, the Company launched a consumer loyalty program, which allows participating customers to earn rewards for qualifying treatments to their patients (i.e. consumers) using Jeuveau® and redeem the rewards for Jeuveau® in the future at no additional cost. The loyalty program represents a customer option that provides a material right and, accordingly, is a performance obligation. At the time Jeuveau® product is sold to customers, the invoice price is allocated between the product sold and the estimated material right reward (“Reward”) that the customer might redeem in the future. The standalone selling price of the Reward is measured based on historical sales data, estimated average selling price of Jeuveau® at the time of redemption, expected customer and consumer participation rates in the loyalty program, and estimated number of qualifying treatments to be performed by customers. The portion of invoice price allocated to the Reward is initially recorded as deferred revenue. Subsequently, when customers redeem the Reward and the related product is delivered, the deferred revenue is recognized in net revenues at that time.

•Co-Branded Marketing Programs — The Company offers eligible customers with a certain level of Jeuveau® purchases to receive advertising co-branded with the Company. The co-branded advertising represents a performance obligation. At the time Jeuveau® product is sold to customers, the invoice price is allocated between the product sold and the advertisement. The standalone selling price of the advertisement is measured based on the estimated market value of similar advertisement adjusted for the customer’s portion of the advertisement. The portion of invoice price allocated to the advertisement is initially recorded as deferred revenue. Subsequently, when the advertisement airs, the deferred revenue is recognized in net revenues at that time.

Contract balances

A contract with a customer states the terms of the sale, including the description, quantity and price of each product purchased. Amounts are recorded as accounts receivable when the Company’s right to consideration becomes unconditional. The Company does not have any significant financing components in customer contracts given the expected time between transfer of the promised products and the payment of the associated consideration is less than one year. As of December 31, 2021 and 2020, all amounts included in accounts receivable, net on the accompanying balance sheets are related to contracts with customers.

The Company did not have any contract assets nor unbilled receivables as of December 31, 2021 or 2020. Sales commissions are included in selling, general and administrative expenses when incurred.

Contract liabilities reflect estimated amounts that the Company is obligated to pay to customers or patients primarily under the rebate and coupon programs and deferred revenue associated with Rewards under the consumer loyalty program and co-

branded marketing programs. The Company’s contract liabilities are included in accounts payable and accrued expenses in the accompanying balance sheets.

As of December 31, 2021 and 2020, the accrued revenue contract liabilities, primarily related to volume-based rebates, consumer loyalty program, and co-branded media programs, were $7,934 and $3,081, respectively, which were recorded in accrued expenses in the accompanying balance sheets. For the years ended December 31, 2021 and 2020, provisions for rebate, coupon, consumer loyalty programs, and co-branded media programs were $16,139 and $16,896, respectively, which were offset by related payments, redemptions and adjustments of $11,286 and $15,524, respectively.

During the years ended December 31, 2021 and 2020, the Company recognized $2,802 and $0, respectively, of revenue related to amounts included in contract liabilities at the beginning of the period and did not recognize any revenue related to changes in transaction prices regarding its contracts with customers from previous periods.

Collectability

Accounts receivable are recorded at the invoiced amount and do not bear interest. At the time of contract inception or new customer account set-up, the Company performs a collectability assessment of the customer’s creditworthiness. The Company assesses the probability that the Company will collect the entitled consideration in exchange for the goods sold, by considering the customer’s ability and intention to pay when consideration is due. On a recurring basis, the Company estimates the amount of receivables considered uncollectable to reflect an allowance for doubtful accounts. The Company writes off accounts receivable balances when it is determined that there is no possibility of collection. As of December 31, 2021 and 2020, allowance for doubtful accounts was $2,385 and $2,118, respectively. For the years ended December 31, 2021 and 2020, provision for bad debts was $589 and $2,066, respectively, and the write-off amount was $322 and $335, respectively.

Practical Expedients

The Company expenses sales commissions when incurred as the amortization period is one year or less. These costs are recorded within selling, general and administrative expenses in the accompanying statements of operations and comprehensive loss. The Company does not adjust the amount of promised consideration for the effects of the time value of money for contracts in which the anticipated period between when the Company transfers the goods or services to the customer and when the customer pays within one year.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development expenses include personnel-related costs, costs associated with pre-clinical and clinical development activities, costs associated with and costs for prototype products that are manufactured prior to market approval for that prototype product, internal and external costs associated with the Company’s regulatory compliance and quality assurance functions, including the costs of outside consultants and contractors that assist in the process of submitting and maintaining regulatory filings, and overhead costs, including allocated facility related expenses.

Stock-Based Compensation

The Company recognizes stock-based compensation expense for employees, consultants and members of the Board of Directors based on the fair value at the date of grant.

The Company uses the Black-Scholes option pricing model to value stock option grants. The Black-Scholes option pricing model requires the input of subjective assumptions, including the expected volatility of the Company’s common stock, expected risk-free interest rate, and the option’s expected life. The fair value of the Company’s restricted stock units (“RSUs”) is based on the fair value on the grant date of the Company’s common stock. The Company also evaluates the impact of modifications made to the original terms of equity awards when they occur.

The fair value of equity awards that are expected to vest is amortized on a straight-line basis over the requisite service period. Stock-based compensation expense is recognized net of actual forfeitures when they occur, as an increase to additional paid-in capital in the balance sheets and in the selling, general and administrative or research and development expenses in the statements of operations and comprehensive loss.

Advertising Costs

Advertising CostsAdvertising costs are expensed as incurred and primarily include costs related to social media ads and co-branded marketing programs. Advertising costs are included in selling, general and administrative expenses.

Income Taxes

The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are determined on the basis of differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse.

A valuation allowance is recorded against deferred tax assets to reduce the net carrying value when it is more likely than not that some portion or all of a deferred tax asset will not be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, and ongoing prudent and feasible tax planning strategies in assessing the amount of the valuation allowance. When the Company establishes or reduces the valuation allowance against its deferred tax assets, its provision for income taxes will increase or decrease, respectively, in the period such determination is made.

Additionally, the Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefit recognized in the financial statements for a particular tax position is based on the largest benefit that is more likely than not to be realized upon settlement. Accordingly, the Company establishes reserves for uncertain tax positions. The Company has not recognized interest or penalties in its statement of operations and comprehensive loss.

The Company is required to file federal and state income tax returns in the United States and various other state jurisdictions. The preparation of these income tax returns requires the Company to interpret the applicable tax laws and regulations in effect in such jurisdictions, which could affect the amount of tax paid by the Company. An amount is accrued for the estimate of additional tax liability, including interest and penalties, for any uncertain tax positions taken or expected to be taken in an income tax return. The Company reviews and updates the accrual for uncertain tax positions as more definitive information becomes available.

The Company’s income tax returns are based on calculations and assumptions that are subject to examination by the Internal Revenue Service and other tax authorities. In addition, the calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. While the Company believes it has appropriate support for the positions taken on its tax returns, the Company regularly assesses the potential outcomes of examinations by tax authorities in determining the adequacy of its provision for income taxes. The Company continually assesses the likelihood and amount of potential revisions and adjusts the income tax provision, income taxes payable and deferred taxes in the period in which the facts that give rise to a revision become known.

The Company monitors changes to the tax laws in the states it conducts business and files corporate income tax returns. The Company does not expect that changes to state tax laws through December 31, 2021 to materially impact its financial statements.

Net Loss Per Share

Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period including contingently issuable shares. Diluted earnings per share is based on the treasury stock method and includes the effect from potential issuance of ordinary shares, such as shares issuable pursuant to the exercise of stock options and the vesting of restricted stock units. The dilutive effect of stock options and restricted stock units is computed under the treasury stock method. The dilutive effect of the Daewoong Convertible Note is computed under the if-converted method. Potentially dilutive securities are excluded from the computations of diluted net loss per share if their effect would be antidilutive.

Recent Accounting Pronouncements

Recently Adopted Pronouncements

In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. FASB issued this update as part of its Simplification Initiative to improve areas of GAAP and reduce cost and complexity while maintaining usefulness. The main provisions remove certain exceptions including the exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. In addition, the amendments simplify income tax accounting in the areas such as income based franchise taxes, eliminating the requirements to allocate consolidated current and deferred tax expense in certain instances and a requirement that an entity reflects the effect of enacted changes in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. For public companies, the standard is effective for fiscal years beginning after December 15, 2020 and interim periods therein. The Company has adopted the guidance on the effective date of January 1, 2021. There are no material impacts to the financial statements as a result of this adoption.

Recent Accounting Pronouncements Issued But Not Adopted

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The update simplifies the accounting for goodwill impairment by removing step two of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will be the amount by which a reporting unit’s carrying amount, including goodwill, exceeds its fair value. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. As amended by ASU No. 2019-10, the updated guidance is effective for the Company as a smaller reporting company beginning January 1, 2023. The standard requires prospective application. Early adoption is permitted. The Company does not expect adoption of this guidance will have a material impact on its financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which modifies the measurement and recognition of credit losses for most financial assets and certain other instruments. The new standard requires the use of forward-looking expected credit loss models based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount, which may result in earlier recognition of credit losses under the new standard. The new guidance also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. Subsequent to the issuance of ASU No. 2016-13, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. This ASU does not change the core principle of the guidance in ASU No. 2016-13, instead these amendments are intended to clarify and improve operability of certain topics included within the credit losses standard. The FASB also subsequently issued ASU No. 2019-04 which did not change the core principle of the guidance in ASU No. 2016-13 but clarified that expected recoveries of amounts previously written off and expected to be written off should be included in the valuation account and should not exceed amounts previously written off and expected to be written off. As amended by ASU No. 2019-10, the updated guidance is effective for the Company as a smaller reporting company beginning January 1, 2023. The Company is in the process of determining the effects the adoption will have on its financial statements and reviewing credit loss models to assess the impact of the adoption of the standard on the financial statements. Based on initial assessments, the Company believes that while adoption will modify the way it analyzes financial instruments, it does not expect adoption of this guidance will have a material impact to its financial statements.

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting and in January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope (“ASU 2021-01”). Both ASU No. 2020-04 and ASU No. 2021-01 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. ASU No. 2020-04 and ASU No. 2021-01 are effective upon issuance for contract modifications and hedging relationships, and the Company is allowed to elect to apply the amendments prospectively through December 31, 2022. The Company does not expect adoption of this guidance will have a material impact on its financial statements.

In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. This update will increase transparency of government assistance received by most business entities by requiring the disclosure of: (1) the types of transactions; (2) the accounting for the transactions; and, (3) the effect of the transactions on a business entity’s financial statements. ASU No. 2021-10 is effective for financial statements issued for annual periods beginning after December 15, 2021, with early application permitted. The Company does not expect adoption of this guidance will have a material impact on its financial statements.

Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants, and the SEC did not, or are not believed by management to, have a material impact on the Company’s present or future financial position, results of operations or cash flows.
