- Categories: Film-Forming/Holding Agents
VP/copolymer is a film-forming agent often used in water-resistant sunscreen products. It helps the sunscreen adhere better to skin and resist breaking down in water. It does not, however, last for hours, which is why you must reapply even water-resistant sunscreens at regular intervals.
