What Is Bemotrizinol? The First New US Sunscreen Ingredient in Decades, Explained
On June 9, 2026, the FDA approved bemotrizinol for use in US sunscreens — the first new sunscreen active ingredient allowed in America since the late 1990s, per NBC News and CNN. If you have ever heard that "European sunscreens are better," this ingredient is a big part of why.
What is bemotrizinol?
Bemotrizinol (also called BEMT, sold abroad under names like Tinosorb S) is a chemical UV filter that absorbs both UVA and UVB rays. It has been used in Europe and Asia since around 2000. Two properties make it stand out:
- Broad-spectrum coverage — strong protection across the UVA range, which drives skin aging and contributes to skin cancer
- Photostability — it does not break down in sunlight, unlike avobenzone, the main UVA filter in US sunscreens, which degrades and needs stabilizing ingredients
Why did US approval take 25 years?
US sunscreens are regulated as over-the-counter drugs, a far slower pathway than the cosmetics framework used in the EU. New filters required extensive safety data under FDA monograph rules, and for two decades no ingredient cleared the bar. The FDA's final order now permits bemotrizinol at concentrations up to 6% and recognizes it as safe and effective for adults and children 6 months and older, per Drug Topics.
When can you buy it?
Brands moved quickly: Neutrogena and Ultra Violette have said the first US products with bemotrizinol are expected on shelves around September 2026, per Marie Claire. Expect lighter-feeling, high-SPF formulas similar to what has been sold in France, Australia, Japan, and South Korea for years.
Does this make current US sunscreens unsafe?
No. Existing FDA-approved sunscreens still work, and the best sunscreen remains the one you will actually wear daily. Bemotrizinol simply expands the options — particularly for people who find current chemical formulas irritating or mineral formulas chalky. For specific skin concerns, a dermatologist is the right resource.
Frequently Asked Questions
Is bemotrizinol a chemical or mineral sunscreen?
Chemical (organic) filter — it absorbs UV rather than sitting on the skin like zinc oxide or titanium dioxide.
Is it safe for children?
The FDA's order covers use in children 6 months and older, the same guidance as existing sunscreens.
Will products say "bemotrizinol" on the label?
Yes — US drug-facts labels list active ingredients by name, so look for bemotrizinol in the actives list starting in late 2026.
