Science
Mechanism of Action
This ingredient functions by forming a non-greasy, protective barrier on the skin's surface, effectively preventing moisture evaporation and enhancing hydration as an occlusive. It also softens and smooths the skin as an emollient, while improving formulation spreadability and absorption for a silky, non-oily finish.
