Science
Mechanism of Action
As a quaternized milk protein, this ingredient is engineered to interact with and adhere to the superficial layers of both skin and hair. For skin, it is believed to facilitate cell restructuring, maintain optimal hydration levels by forming a protective film that limits moisture evaporation, and impart anti-irritant and protective properties. This mechanism collectively contributes to visibly smoother and more hydrated skin.
