Science
Mechanism of Action
Functions as both an emollient and occlusive agent by delivering oleic, stearic, linoleic, and palmitic acids that integrate directly into the skin's lipid bilayer to restore barrier integrity. The unsaponifiable fraction provides complementary anti-inflammatory and antioxidant activity through naturally occurring vitamins A and E, helping to calm irritation while reinforcing moisture retention.
