Science
Mechanism of Action
This ingredient operates by forming a protective, occlusive barrier within the skin's uppermost layer, effectively filling the microscopic gaps between skin cells. This action is crucial for retaining the skin's natural moisture and providing a defensive shield against environmental irritants and microbial agents. The outcome is a noticeably smoother and better-conditioned skin surface. Beyond its direct skin benefits, Propanediol Dicaprylate/Caprate is also highly effective at dispersing and emulsifying various formulation components, including pigments and active sunscreen ingredients.
