Science
Mechanism of Action
As a chemically inert polymer, Polyvinylidene Difluoride (PVDF) does not possess intrinsic biochemical activity on the skin. Its function in skincare is anticipated to be mechanistic, acting as a structural component, forming a protective barrier, or facilitating controlled release as a hydrophobic membrane or drug reservoir within sophisticated delivery systems. Its established biocompatibility contributes to a low incidence of inflammatory reactions.
