Science

Mechanism of Action

This ingredient functions by creating a protective, breathable film on the skin's surface, effectively reducing transepidermal water loss and maintaining optimal moisture levels. It significantly improves the sensory profile of cosmetic formulations, offering a quickly absorbed, non-tacky feel. Additionally, it serves as an excellent solvent, enhancing the dispersion and effectiveness of active ingredients, particularly lipophilic compounds like vitamins A, C, and E, and assists in solubilizing sebum, dirt, and color cosmetics.
