Science
Mechanism of Action
This ingredient functions by modulating the synthesis of ceramides, which are essential components of the skin's lipid barrier, thereby enhancing its integrity and function. It also inhibits microbial adherence on the skin surface, possesses inherent anti-inflammatory and antimicrobial properties, and integrates into the skin's lipid matrix to influence key cellular processes beneficial for overall dermal health.
