PVP (polyvinylpyrrolidone) is a synthetic water-soluble polymer used in skincare and cosmetics as a film-forming agent, binder, and viscosity adjuster, commonly found in hair styling products, mascaras, and some topical formulations. It forms a flexible film on the skin or hair surface to help hold and distribute other ingredients.
