Science
Mechanism of Action
This ingredient functions principally as an emulsifier, critical for creating uniform and stable oil-in-water or water-in-oil emulsions in skincare products. It forms a protective film on the skin's surface, acting as an emollient to reduce moisture loss and improve skin texture. As a mild cleansing agent, it helps to gently remove impurities without compromising the skin's natural barrier. While specific research on Polyglyceryl-4 Dilaurate for these actions is limited, studies on the closely related Polyglyceryl-4 Laurate suggest potential roles in enhancing the penetration of active ingredients like ceramides, vitamin C, and retinol, as well as possessing moisturizing and antibacterial properties.
