Science

Mechanism of Action

This ingredient functions as an effective humectant, actively attracting and binding moisture to the skin to boost hydration, resulting in a softer and smoother epidermal surface. It forms a protective film, which also helps to absorb excess oil and moisture, delivering a desirable matte appearance particularly beneficial for oily or combination skin. Additionally, it acts as a skin conditioning agent, a viscosity regulator to optimize product consistency and spreadability, and a binding agent that maintains formula integrity and stabilizes emulsions to prevent ingredient separation.
