Science
Mechanism of Action
This high molecular weight, water-soluble cationic polymer establishes a continuous, invisible film on the skin's surface. Its inherent positive charge enables it to ionically bond with the naturally negatively charged areas of the skin, forming a substantive protective barrier. This film actively minimizes transepidermal water loss, provides a shield against environmental irritants, and contributes to a smoother, more hydrated complexion by enhancing overall skin feel and reducing potential irritation.
