Science

Mechanism of Action

POLYGLYCERYL-3/LAURYL POLYDIMETHYLSILOXYETHYL DIMETHICONE CROSSPOLYMER operates by creating an occlusive yet breathable layer on the skin's surface. This film physically hinders transepidermal water loss, thereby increasing skin hydration and maintaining optimal moisture balance. Beyond moisture retention, this polymeric barrier offers protection against external environmental aggressors, including pollutants and UV radiation. Its unique structure contributes a smooth, non-tacky feel, facilitating effortless application and even distribution of skincare products. Furthermore, it functions as a humectant, drawing moisture to the skin, and can optimize the penetration and distribution of other active ingredients into deeper epidermal layers, while also mitigating potential irritant effects from companion ingredients.
