Bemotrizinol, sold as Parsol Shield, Tinosorb S, and Escalol S, is an oil-soluble UV filter now approved in U.S. sunscreens. It offers broadened protection and potential advantages over existing filters.
The FDA has approved bemotrizinol (BEMT) for over‑the‑counter sunscreens, marking a modernization in U.S. UV protection. The ingredient absorbs both UVA and UVB rays, is photostable, and will debut as Parsol Shield before broader market adoption after an 18‑month exclusivity period. Industry and dermatology experts say the move could improve protection and user experience, though rollout and formulation timelines remain.
