Science
Mechanism of Action
This ingredient primarily enhances the skin's natural barrier by supplying beneficial exogenous lipids, which boosts hydration and offers protection from inflammatory responses. It forms a protective layer on the skin's surface, effectively minimizing transepidermal water loss. Beyond its skin benefits, it functions as a non-ionic emulsifier, ensuring the stability and homogeneity of oil-in-water cosmetic formulations. Furthermore, it aids in skin cleansing by reducing surface tension within the stratum corneum, facilitating the removal of impurities.
