FDA clears bemotrizinol, the first new U.S. sunscreen ingredient in 25 years
The FDA has approved the chemical bemotrizinol, now marketed as BEMT, making it the first new sunscreen component in the United States in over two decades.
After a June review, the U.S. Food and Drug Administration approved bemotrizinol—often abbreviated as BEMT—introducing the first new chemical sunscreen ingredient in the country in 25 years. The filter, already popular in Europe, is now being sold in American stores in formulations from Neutrogena and other brands, offering broad-spectrum protection against both UVA and UVB rays without the white streaks associated with mineral sunscreens such as zinc oxide.
Dermatologists highlight that BEMT’s large molecular size limits skin penetration, and clinical trials with over 500 volunteers found virtually no systemic absorption or allergic reactions. Compared with avobenzone, the only other UVA-filter, BEMT remains stable under sunlight, reducing the need for additional stabilizers. Environmental reviews suggest limited reef toxicity, though longer-term studies are still pending. Experts advise that sunscreen should be part of a broader sun-safety routine that includes shade, clothing, and regular reapplication.
Why it matters
