Polysilicone-15 (also known as Parsol SLX) is a silicone-based organic UV filter that absorbs UVB radiation, commonly used in sunscreens and daytime cosmetic products to provide photoprotection and improve formulation feel. It is a film-forming polymer that helps stabilize and enhance the efficacy of other UV filters.
