Science
Mechanism of Action
This ingredient, a triester of glycerin and acetyl hydroxystearic acid, works by creating a lipid-compatible, protective film on the skin. This barrier helps to reduce transepidermal water loss, thereby maintaining skin hydration, providing lubrication, and contributing to softer, smoother skin.
