Science
Mechanism of Action
This ingredient functions by enriching the skin's surface with a blend of triglycerides, including oleic, palmitic, stearic, and linoleic acids, which are characteristic of its tallow origin. These fatty acids can penetrate the epidermis, potentially enhancing the skin's natural lipid content and supporting its barrier function. As an emollient, it forms a protective film to reduce moisture loss and improve skin texture. Additionally, its emulsifying action stabilizes cosmetic emulsions by lowering the interfacial tension between immiscible liquids.
