OLEIC/PALMITIC TRIGLYCERIDE.

Valuable / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

Oleic/Palmitic Triglyceride is a skin-conditioning emollient that replenishes the skin's lipid matrix, providing deep moisturization and supporting the skin barrier. It effectively reduces transepidermal water loss (TEWL), leaving the skin soft and conditioned without a greasy feel.

Science

Mechanism of Action

This triglyceride functions primarily as an emollient, delivering significant moisturization and supporting the skin's natural barrier by supplementing its lipid structure. By forming a protective layer, it minimizes transepidermal water loss (TEWL), thereby enhancing skin hydration and conditioning. The palmitic acid component is crucial for promoting epidermal morphogenesis and the proper execution of early differentiation programs, which are vital for robust barrier formation. Oleic acid, another key component, is also known for its ability to enhance the penetration of other active ingredients into the skin.
