UV filter, a.k.a. Tinosorb S, first new sunscreen ingredient in 25+ years
The FDA has approved bemotrizinol (BEMT) for over‑the‑counter sunscreens, a move hailed as a major modernization. The ingredient blocks both UVA and UVB rays, is photostable, and will be sold under Parsol Shield before broader market adoption after 18 months. Experts say the update will improve protection and user experience, though supply and formulation timelines remain a factor.
The FDA has approved bemotrizinol, a chemical UV filter used in European and Asian sunscreens for over 20 years. It offers UVA and UVB protection, is photostable, and may lead to more elegant, higher-SPF products in the US. The move comes after decades of FDA inaction on new filters, with products containing bemotrizinol expected to reach US shelves after about 18 months.
