The U.S. Food and Drug Administration approved bemotrizinol as a new UV-filter sunscreen ingredient this week [1, 2].
The decision ends a multi-decade stagnation in American sun protection technology. By introducing a modern filter, the agency aims to expand available options for consumers and improve protection against harmful ultraviolet rays [1, 3].
Bemotrizinol, also known as Tinosorb M, is the first new sunscreen ingredient approved in the U.S. in 20 to 25 years [1, 4]. While the exact timeframe of the previous approval varies by report, the gap represents a significant period without new chemical filters entering the domestic market [1, 4].
This ingredient has already established a long track record of use outside the United States. Robert F. Kennedy Jr. said that bemotrizinol has been used safely in Europe for decades [3]. He said that the action will increase competition and consumer confidence in sunscreen products [3].
Medical professionals have noted the importance of this shift for public health. Dermatologist Dr. Whitney Bowe said the new UV filter has implications for skin protection [2]. The move is intended to align U.S. standards with global benchmarks for UV filtration.
Advocates for consumer health have praised the regulatory shift. Alexa Friedman said that American consumers deserve access to the best available sun protection, and that they are finally getting closer to it [1].
The FDA announced the decision from Washington, D.C., focusing on the goal of increasing the range of UV-filter options available to the public [1, 2].
“American consumers deserve access to the best available sun protection.”
This approval signals a pivot in the FDA's approach to sunscreen regulation, moving away from a decades-long freeze on new active ingredients. By approving bemotrizinol, the U.S. is closing the gap between domestic sun care and the more advanced formulations available in Europe and Asia, which may lead to more stable, broad-spectrum products that are easier for consumers to apply and maintain.
