Science
Mechanism of Action
This ingredient functions as an emollient by creating a smooth surface on the skin, minimizing microscopic gaps between cells to reduce transepidermal water loss and bolster the skin's protective barrier against environmental aggressors. Its humectant properties attract and bind moisture to the skin, contributing to hydration. As an emulsifier, it expertly blends oil and water components, preventing phase separation and ensuring product homogeneity. Furthermore, it acts as a surfactant to lower surface tension, aiding in the removal of impurities, and as an excellent dispersant for inorganic powders and pigments.
