Science
Mechanism of Action
This ingredient functions as a positively charged (cationic) polymer. Its mechanism involves electrostatic bonding, drawing it to the naturally negatively charged sites present on the skin and hair surface. Through a dilution and deposition process, it adheres, creating a tenacious film. This polymeric film acts as a humectant, drawing and binding moisture to the skin to enhance hydration. Simultaneously, it forms a protective occlusive barrier that guards against external irritants and reduces moisture evaporation from the skin.
