Science
Mechanism of Action
This ingredient operates by filling microscopic voids in the skin's surface, forming a protective barrier that reduces transepidermal water loss and shields against environmental aggressors, thereby boosting skin hydration and integrity. Beyond its direct skin benefits, it acts as a viscosity-increasing agent in formulations, a binder, a wetting agent for pigments and UV filters, and also possesses emulsifying and surfactant properties.
