Science
Mechanism of Action
Upon topical application, Glyceryl Palmitate/Stearate acts as an emollient, providing a lubricating effect on the skin's surface, which contributes to a soft and smooth tactile experience. It forms a protective, occlusive barrier, which is instrumental in reducing transepidermal water loss and thus maintaining skin hydration. This ingredient also exhibits antioxidant properties, offering a degree of protection against environmental free radical damage. Furthermore, within formulations, it serves as an emulsifier, stabilizing oil and water phases and assisting in the precise balance of the product's pH.
