Science

Mechanism of Action

This ingredient actively softens and smooths the skin by forming a light, non-occlusive layer that enhances barrier function and reduces transepidermal water loss. In formulations, it serves as a robust stabilizing agent, ensuring uniform distribution of ingredients, and effectively disperses pigments for consistent color. Furthermore, it acts as an efficient solvent for UV filters in sun care products, improving their emulsification and spreadability.
