Science

Mechanism of Action

This ingredient operates by forming a lightweight, protective film on the skin's surface, which actively aids in retaining natural moisture and bolstering the skin's inherent barrier function. Its molecular structure allows for rapid absorption, imparting a non-oily texture akin to silicones. Furthermore, it acts as a solvent in formulations, facilitating the optimal dispersion of challenging ingredients like organic UV filters and pigments, ensuring uniform application and efficacy.
