Sunscreen just got a new ingredient
For the first time in more than two decades, the US has approved a new sunscreen filter. Here is what bemotrizinol does and how to find it.
The short version
Bemotrizinol, also called BEMT or Tinosorb S, has been used in Europe and Asia for years. The US Food and Drug Administration approved it in June 2026, and the first US sunscreens that contain it reached shelves this autumn. It protects against both UVA and UVB light, holds up well in sunlight and leaves little or no white cast.
How it unfolded
Outlets disagree on whether this is the first new filter in 20, 25 or 30 years, depending on how they date the last addition. All agree it is the first in a very long time.
- June 9
- The FDA issues a final order adding bemotrizinol to the over-the-counter sunscreen list as generally recognised as safe and effective, at up to 6%, for adults and children aged six months and older.
- August
- The order takes effect, so brands can legally sell sunscreens that use the filter.
- August 31
- Australian brand Ultra Violette launches Unblock Screen SPF 50 at Sephora, among the first BEMT formulas on US shelves.
- September 17
- Neutrogena follows as the first US drugstore brand, with two Cloud-Tech sunscreens on Amazon, including an SPF 70.
- Through 2027
- More brands are expected to reformulate their sunscreens with the filter.
Why it matters for your skin
It stays stable in the sun
Reports say it keeps over 90% of its protection after long sun exposure. Avobenzone, the other non-mineral filter that covers UVA in the US, breaks down faster.
Less white cast
It can be paired with zinc oxide for strong, broad protection that looks lighter on the skin, which helps people with deeper skin tones.
Better odds you will wear it
Lighter textures that sit well under makeup make daily use easier, and the best sunscreen is the one you actually apply.
How it compares

|---|---|---|---|
| Type | Chemical (organic) filter | Chemical (organic) filter | Mineral filter |
| Protection | Broad spectrum, UVA and UVB | Mainly UVA | Broad spectrum |
| Stability in sun | High, keeps most of its strength | Lower, breaks down faster | High |
| White cast | Little or none | None | Can leave a visible cast |

How to use it well
- Read the Drug Facts panel. Look for bemotrizinol under active ingredients. Many foreign formulas cannot be sold in the US because they use other filters the FDA has not approved.
- Choose SPF 30 or higher with broad spectrum on the label. The new filter helps, but the usual rules still apply.
- Apply generously and reapply. Use plenty on your face and neck, and reapply about every two hours outdoors or after swimming or sweating.
- Patch test if your skin is sensitive. Any new filter can irritate some people, so try a small amount on your inner arm first.
- Keep the other habits. Shade, hats and clothing still matter, especially in strong midday sun.
Better sunscreen is only useful if it is comfortable enough to wear every day. This new filter makes that a little easier.
