The FDA recently approved bemotrizinol, an organic filter that absorbs UVA and UVB rays, for use in U.S. sunscreens. The filter has been used internationally for years, and products featuring it are beginning to appear in the U.S.; the finished formula, not one ingredient alone, determines a sunscreen’s protection and feel.
The FDA has approved bemotrizinol for U.S. sunscreens, clearing the way for American formulators to use a UV filter that has been available in other markets for years. Products containing it are beginning to reach U.S. shoppers. The approval adds an option for sunscreen makers, but the ingredient alone does not determine a product’s protection, feel, or suitability.
Bemotrizinol, also called BEMT, is an organic UV filter that absorbs both UVA and UVB radiation. The American Chemical Society describes its absorption ranges as 315 to 400 nanometers for UVA and 280 to 315 nanometers for UVB. The filter was developed in Switzerland in the 1990s and was first used in European Union sunscreens in 2000, according to the source report.
Stephen Lynch, associate vice president of skincare development and scientific valorization at L’Oréal Research and Innovation North America, said BEMT gives sunscreen developers another tool. He said it offers coverage across UVA and UVB wavelengths, including the short-UVA range. Lynch also cautioned against judging a sunscreen by a single ingredient: the combination of filters, the formulation, and testing of the finished product all affect protection, stability, texture, and user experience.
The report describes U.S. products featuring BEMT, including Ultra Violette Unblock Screen SPF 50, a hybrid formula containing BEMT, octocrylene, and zinc oxide, and La Roche-Posay Anthelios UV Defense Sunscreen SPF 50. The reviewer described Unblock as lightweight and subtly tinted, reporting no visible white cast on her brown skin. Those are the reviewer’s observations, not a guarantee that the product will feel or look the same for every user.
More Filter Options for U.S. Sunscreens
For U.S. shoppers, the approval broadens the pool of UV filters companies can use when developing sunscreens. This may give brands more flexibility to create products with different textures and finishes. That can matter during winter, when some people find heavier or visibly chalky products less appealing and may be less likely to apply sunscreen consistently. The reported product review offers one example of a formula the writer found comfortable, but it does not establish that BEMT itself makes sunscreen easier to wear.
The change is also relevant to people seeking sunscreen that leaves less visible residue. The source reviewer, who has brown skin, said the tint in Ultra Violette’s formula prevented a white cast for her. Individual results can vary with skin tone, product amount, and formula. Adding BEMT does not replace broad-spectrum testing, nor does it mean every product containing the filter will suit every skin type. People with sensitivities may prefer another formula, including a mineral option, based on their own experience and professional advice.

A Long-Used Filter Reaches the U.S.
The report frames the approval against a difference between U.S. sunscreen regulations and markets such as Europe and South Korea, where some filters have been used before becoming available in American products. It calls BEMT the first sunscreen filter approved in the United States in 20 years. That characterization comes from the source report; the supplied material does not provide a separate FDA statement or a full regulatory timeline to independently detail the comparison.
Although its U.S. approval is recent, BEMT is not a newly discovered ingredient globally. Lynch said L’Oréal has experience formulating with it internationally and that it has been used in La Roche-Posay formulas abroad. The distinction matters: new to U.S. use does not mean new to global sunscreen formulation. At the same time, performance claims still need to be considered product by product, based on the finished sunscreen and its testing.
“It provides protection across both UVA and UVB wavelengths, which makes it a useful addition to the sunscreen formulator’s toolbox.”
— Stephen Lynch, associate vice president of skincare development and scientific valorization at L’Oréal Research and Innovation North America
Product Performance Still Varies
The source material does not include the FDA’s announcement, the exact date of approval, or details of the agency’s review, so those points cannot be independently specified here. It also does not provide a complete launch schedule, price information, or ingredient concentrations for the named products. The report notes that products featuring BEMT are rolling out, but availability may differ by retailer and location.
It remains unclear from the supplied information how each new formula performs in standardized testing or how its protection compares with other sunscreens. Lynch’s explanation is that a finished product’s properties depend on its complete formulation and testing. The reported impressions of texture, oil control, and white cast are personal observations; skin can react differently, and some people may find that a different filter type works better for them.
More Formulas May Follow
As U.S. brands begin using the newly approved filter, shoppers can expect to see whether more products featuring BEMT reach stores. The source report identifies Ultra Violette Unblock Screen SPF 50 and La Roche-Posay Anthelios UV Defense Sunscreen SPF 50, but does not give a detailed schedule for additional launches. Consumers evaluating a product should check its label and claims, and consider the formula as a whole rather than selecting it on the basis of BEMT alone.
Further reporting could clarify the approval’s timing and regulatory details, as well as the availability and tested characteristics of individual products. Until then, the confirmed development is a broader set of ingredients available to U.S. sunscreen makers; the likely effect on consumer choice will depend on which products launch and how people respond to their formulations.
Key Questions
What is bemotrizinol?
Bemotrizinol, or BEMT, is an organic UV filter that absorbs UVA and UVB radiation. It has been used in sunscreens outside the United States for years and was recently approved for U.S. sunscreen use, according to the source report.
Does BEMT make a sunscreen more effective than mineral sunscreen?
The supplied report does not establish that. L’Oréal’s Stephen Lynch said organic and mineral filters work differently and both can be used to make effective broad-spectrum sunscreens. The finished formula and its testing determine its performance.
Will sunscreen with BEMT leave no white cast?
Not necessarily. The reviewer reported that the tint in Ultra Violette Unblock Screen SPF 50 left no visible white cast on her skin. That is a personal product review, not a result that applies to every BEMT sunscreen or every user.
Which products in the report contain BEMT?
The report names Ultra Violette Unblock Screen SPF 50 and La Roche-Posay Anthelios UV Defense Sunscreen SPF 50. It does not provide a full list of U.S. products containing the filter or a complete account of their availability.
