Science

Mechanism of Action

This ingredient functions synergistically as an emulsifier, stabilizer, and film-forming agent. It expertly blends oil and water components, ensuring smooth and consistent product textures while preventing separation. On the skin, it forms a soft, flexible barrier that reduces transepidermal water loss and offers protection against environmental stressors. Its emollient properties soften and smooth the skin, aiding in moisture retention, with reported water retention capabilities as high as 500%. Additionally, it helps control product viscosity, disperses pigments effectively, and offers antioxidant benefits.
