other● Benefits
Polyvinyl Alcohol forms a cohesive, flexible film on the skin surface, which is the functional basis for peel-off mask and pore strip formats. It also helps regulate the texture and consistency of formulations through viscosity control. Evidence for these roles is well-established in cosmetic formulation science.
