Aiming to provide effective and tolerable topical therapies to achieve local action THE SCIENCE BEHIND OUR PROPRIETARY TECHNOLOGY

Silica-based shell wraps the BPO crystal and is intended to serve as a barrier between the BPO crystals and the skin CRYO-SEM PICTURE After application onto skin, BPO slowly migrates through the shell resulting in a continuous flow of BPO for up to 24 hours ENERGY-DISPERSIVE X-RAY SPECTROSCOPY MAPPING ENCAPSULATED BENZOYL PEROXIDE (E-BPO) ENCAPSULATION IS DESIGNED TO ALLOW FOR CONTINUOUS FLOW

Complete encapsulation allows stabilization of tretinoin in the presence of BPO SEM PICTURE Silica-based shell allows for slow delivery of tretinoin to the skin over time SEM PICTURE ENCAPSULATED TRETINOIN (E-TRETINOIN) ENCAPSULATION IS DESIGNED TO ENHANCE STABILITY
