Science
Mechanism of Action
This ingredient functions by creating a fine, lubricating film on the skin's surface, which diminishes trans-epidermal water loss and contributes to improved hydration. Beyond its direct skin benefits, Isoamyl Stearate significantly enhances the aesthetic and functional properties of products, boosting their spreadability and ensuring a refined, light skin feel. It additionally serves a dual role as a solvent for other components and a binder to stabilize formulations.
