Science
Mechanism of Action
This ingredient exerts its effects primarily through two mechanisms: film-forming and humectancy. As a film-forming agent, it creates a thin, cohesive polymer matrix on the surface of the skin or hair, serving as a barrier that minimizes transepidermal water loss and provides a smooth texture. Concurrently, its humectant properties allow it to bind water molecules, enhancing the intrinsic moisture content of the skin and hair and contributing to their pliability and health.
