Debt Disclosure [Text Block] | NOTE 13. CONVERTIBLE NOTES Unsecured Convertible Notes In March 2024, the Company issued $525 thousand aggregate principal amount of unsecured convertible notes (the “Unsecured Convertible Notes”) in conjunction with the 2024 Subsidiary Guarantee Termination. The 2024 Subsidiary Guarantee Termination was executed with certain holders of the Secured Convertible Notes in order to close the DERMAdoctor Divestiture (see additional discussion in Note 11, “Financing Activities” and Note 21, “DERMAdoctor Divestiture and Discontinued Operations”). The Unsecured Convertible Notes are due March 25, 2026 and bear no stated interest. The Unsecured Convertible Notes may be converted or redeemed for a conversion price equal to $0.14 per share ($4.90 per share post-Reverse Stock Split) at any time at the election of the holder up to the amount of outstanding principal at the time of conversion subject to certain limitations such as beneficial ownership limitations. Upon issuance and as of December 31, 2024, the Unsecured Convertible Notes were convertible for up to 3,750,000 shares of common stock (107,146 shares post-Reverse Stock Split). Upon issuance in March 2024, the lender’s conversion option under the Unsecured Convertible Notes represented an embedded call option requiring bifurcation as an embedded derivative liability because the common stock underlying the option required stockholder approval before the option could be exercised. The fair value of the embedded derivative was determined to be $159 thousand as of March 31, 2024 in accordance with a Black Scholes valuation model. See also Note 3, “Fair Value Measurements,” subheading “Black Scholes Valuation Models and Assumptions.” Upon stockholder approval on May 28, 2024, the embedded call option no longer required liability treatment and was reclassified to equity. The fair value of the embedded derivative liability was determined to be $242 thousand as of May 28, 2024. The change of $83 thousand in fair value between March 31, 2024 and May 28, 2024 was recorded as a non-cash loss on change in fair value of embedded derivative liability in the consolidated statements of operations. See also Note 3, “Fair Value Measurements,” subheading “Black Scholes Valuation Models and Assumptions.” The discount to the note recorded for the embedded derivative liability upon issuance and debt issuance costs are being amortized to interest expense using the effective interest rate method over the term of the Unsecured Convertible Notes, assuming that the Unsecured Convertible Notes will be redeemed for cash of $525 thousand at time of maturity as of March 25, 2026. During the year ended December 31, 2024, the effective interest rate on the Unsecured Convertible Notes was 144%. During the year ended December 31, 2024, interest expense recognized, including amortization of the issuance costs and debt discount, was $62 thousand, which was included in other expense, net in the consolidated statements of operations. Secured Convertible Notes In May 2023, the Company issued $3.3 million aggregate principal amount Original Issue Discount Senior Secured Convertible Debentures (the “Secured Convertible Notes”) in conjunction with the 2023 Private Placement (see Note 11, “Financing Activities”). The Secured Convertible Notes were issued with a $300 thousand original issue discount. The Secured Convertible Notes were originally due November 1, 2024 and were repaid in full during the third quarter of 2024 from the proceeds of the 2024 Public Offering. The Company paid $13 thousand more than the carrying amount of the Secured Convertible Notes, resulting in a loss on extinguishment that was expensed as “Extinguishment of Secured Convertible Notes” in the consolidated statements of operations. Upon full repayment, the Company was released from any further obligations under the Secured Convertible Notes with the lenders. Prior to being paid off, the Secured Convertible Notes could be converted or redeemed for a conversion price equal to $1.30 per share ($45.50 per share post-Reverse Stock Split) at any time at the election of the holder up to the amount of outstanding principal at the time of conversion subject to certain limitations such as beneficial ownership limitations. Upon issuance, the Secured Convertible Notes were convertible for up to 2,538,464 shares of common stock (72,528 shares post-Reverse Stock Split). Beginning June 1, 2023, the Company was required to start making a monthly redemption of 1/18th of the original principal amount of the Secured Convertible Notes. Each monthly redemption reduced the outstanding principle of the Secured Convertible Note by $183 thousand and could be made in cash or, under limiting conditions, in stock at the election of the Company. Monthly redemption in cash required a total payment of $193 thousand. Monthly redemption in stock required the issuance of shares equal to $193 thousand divided by the lower of (i) $45.50 or (ii) 90% of the Company’s common stock’s average volume-weighted average price over 10 trading days prior to the redemption. The conditions allowing for redemption in stock were not met and the Company made all monthly redemption payments in cash. The Secured Convertible Notes also provided for a redemption equal to up to 20% of the gross proceeds received by the Company from any financing completed while the Secured Convertible Notes were outstanding. In connection with the 2023 Warrant Reprice Transaction (see Note 15, “Stockholders’ Equity”), the Company made such a payment totaling $126 thousand in cash against the Secured Convertible Notes. In connection with the 2024 Warrant Reprice Transaction (see Note 15, “Stockholders’ Equity”), the Company made such a payment totaling $45 thousand in cash against the Secured Convertible Notes. In connection with the 2024 Public Offering (see Note 15, “Stockholders’ Equity”), the Company repaid the remaining balance of the Secured Convertible Notes with a payment totaling $433 thousand in cash. Upon issuance in May 2023, the lender’s conversion option under the Secured Convertible Notes represented an embedded call option requiring bifurcation as an embedded derivative liability because the common stock underlying the option required stockholder approval before the option could be exercised. The fair value of the embedded derivative was determined to be $209 thousand as of the date of issuance. After stockholder approval of the underlying common stock, the embedded call option no longer required liability treatment and was reclassified to equity. The fair value of the embedded derivative liability was determined to be $169 thousand upon stockholder approval. The change of $40 thousand in fair value between the date of issuance and stockholder approval was recorded as a non-cash gain on change in fair value of embedded derivative liability in the consolidated statements of operations. See also Note 3, “Fair Value Measurements,” subheading “Black Scholes Valuation Models and Assumptions.” The lender’s subsequent financing redemption option and certain events of default also represented embedded call options and the Company’s monthly share redemption option represented an embedded put option. The fair value of these options was determined to be immaterial upon issuance and at each subsequent reporting date. The Company allocated $1.2 million of gross proceeds from the 2023 Private Placement to the Secured Convertible Notes. The difference between the $1.2 million allocated to the Secured Convertible Notes and the $3.3 million aggregate principal amount represented discounts for the portion of proceeds allocated to the embedded derivative liability and the May 2023 Warrants (See Note 14, “Common Stock Warrants and Warrant Liabilities”) as well as the $0.3 million original issue discount. The Company also allocated $0.3 million of debt issuance costs to the Secured Convertible Notes. The discounts and debt issuance costs were amortized to interest expense using the effective interest rate method over the term of the Secured Convertible Notes. The effective interest rate on the Secured Convertible Notes was 173%. During the year ended December 31, 2024, interest expense recognized, including amortization of the issuance costs and debt discount, was $0.8 million which was included in other expense, net in the consolidated statements of operations.
