Science
Mechanism of Action
Functions as a film-forming polymer that deposits a continuous, flexible barrier upon solvent evaporation. This polymeric film provides water resistance, enhances ingredient adhesion, and creates a controlled-release reservoir system that regulates substance penetration into the stratum corneum while improving product durability and performance.
