Bemotrizinol is a well-tested sunscreen filter that the US has just allowed. It is not a new invention. It protects against both UVA and UVB, holds up well in sunlight, and barely passes through the skin. If you live outside the US, you may already own a sunscreen that contains it. If you live in the US, it gives you more choice, especially if heavy or chalky formulas kept you from wearing sunscreen. It does not make the sunscreen you already use and like obsolete.
The US Food and Drug Administration (FDA) added bemotrizinol to its list of approved sunscreen ingredients on June 10, 2026. It is the first new active ingredient added to that list in more than a quarter of a century. By mid-October 2026, products containing it were on US store shelves, as the Associated Press reported.
This article belongs to our Sunscreen & Sun Protection guide. Store availability and rules below were checked on October 19, 2026, and can change.
A 60-second check before you buy
- Do you like the sunscreen you have? If you wear it every day without trouble, you have no reason to replace it.
- What stopped you before? If it was white cast, a greasy feel, or stinging eyes, a bemotrizinol formula is one more option to try. It is not a guaranteed fix.
- What does the label say? Look for SPF 30 or higher and “Broad Spectrum” (US) or a UVA logo (EU and UK).
- Who is it for? If it is for a baby under 6 months, ask a doctor first.
What it is (and its 5 names)
Bemotrizinol is an organic (also called “chemical”) UV filter. A UV filter is the ingredient in a sunscreen that absorbs ultraviolet light before it reaches your skin. Each filter absorbs some wavelengths better than others. Bemotrizinol has two absorption peaks: one in the UVB range, which mainly causes sunburn, and one in the UVA range, which goes deeper and adds to skin aging. That is why one filter can cover both.
It goes by several names, which is why so many people miss it:
- Bemotrizinol: the name the FDA uses, and what US labels show.
- BEMT: the short form used in news stories and on social media.
- Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine: the standard cosmetic ingredient name (INCI) used on labels in the EU, UK and much of Asia.
- Tinosorb S: the trade name used by BASF, one of its suppliers.
- Escalol S or Parsol Shield: trade names from other suppliers.
All five describe the same molecule.
Why the US took more than 25 years
In the US, sunscreen is a medicine. In most other countries, it is a cosmetic. That one difference explains most of the gap.
The FDA says so directly in its final order: sunscreens are meant to prevent sunburn, so US law treats them as drugs. Drugs must meet drug safety and effectiveness standards before they can be sold. A filter that Europe’s cosmetic rules allowed decades ago still needed its own US review.
For years, adding a sunscreen ingredient in the US took a slow, full rule-making process. A 2020 reform gave companies a faster route, called an order request. Here is how bemotrizinol used it:
| Date | Step |
|---|---|
| September 23, 2024 | Its maker, DSM, asked the FDA to add it |
| December 2025 | The FDA proposed adding it and invited public comment |
| June 10, 2026 | The FDA issued its final order |
| August 9, 2026 | The order took effect |
| Late summer to October 2026 | The first products went on sale in the US |
Many public comments, the FDA noted, pointed out that the ingredient “has been used safely for decades in numerous other countries” and expressed frustration at the wait.
What it does well
It covers UVA and UVB in one filter
Many US sunscreens use several filters together to cover the full UV range. Bemotrizinol covers both on its own. Formulators can combine it with other filters for even coverage.
It holds up in sunlight
Some filters break down as they absorb UV, so their protection fades during the day. Avobenzone, a common UVA filter, is the best-known example. Bemotrizinol is very stable in sunlight and can also help stabilize avobenzone in the same formula. Stability is not a reason to skip reapplying: sweat, water, towels and rubbing still remove sunscreen.
Very little reaches the bloodstream
In the FDA’s review, bemotrizinol was “not readily absorbed through human skin, even with repeat application.” The studies also found no irritation or light-triggered allergic reactions. Dr. Jennifer Stein of NYU Langone told the AP it is “a molecule that’s too big to really penetrate through the skin.”
Where the evidence is thinner
The FDA’s review of daily use covered weeks, not years. The longer track record comes from use in other countries. Evidence on its environmental effects is still limited, and “reef safe” has no official US definition.
How to spot it on a label
Where you look depends on where the product was made to be sold.
| Where it is sold | What the label says | Where to look |
|---|---|---|
| United States | Bemotrizinol, with a percentage (up to 6%) | The “Active ingredients” line in the Drug Facts box |
| EU, UK and most of Asia | Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine | The full ingredient list, usually near the start |
| Product pages and ads | Tinosorb S, BEMT, Parsol Shield or Escalol S | Front of the pack, website, or social media posts |
One detail matters for people who buy sunscreen abroad. The US allows up to 6% bemotrizinol. The EU allows up to 10%, a limit its scientific committee reviewed in 1999, and China allows 10% too. So a product sold under the same brand name in two countries may not have the same formula. Read the label on the one in your hand.
Products on US shelves include Neutrogena Ultra Sheer Daily Face Sunscreen SPF 70 and Ultra Violette Unblock Screen SPF 50. On October 16, 2026, Medscape reported a second Neutrogena product, Clear Face Sunscreen SPF 60, and said CeraVe and La Roche-Posay would launch US products soon. Ranges change quickly, so check the Drug Facts box. One reason the list is short: the FDA order gives DSM, the company that asked for it, and the brands it licenses 18 months of US exclusivity from August 9, 2026.
Does it make sunscreen “better”?
A good filter does not guarantee a good sunscreen. The protection you get depends on the whole product: every filter in it, how much of each, how the formula spreads, and how much you apply.
That is why the labels test the finished product, not the ingredients:
- SPF measures protection from sunburn, which comes mostly from UVB.
- “Broad Spectrum” on a US label means the product passed the FDA’s UVA test.
- A UVA logo in a circle on EU and UK products means its UVA protection is at least a third of its SPF.
A bemotrizinol sunscreen with SPF 50 and broad-spectrum protection has passed the same tests as any other SPF 50 broad-spectrum product. Where it can help is in how the product feels to wear. Because it is so efficient and stable, formulators have more room to make thin, comfortable textures. If a sunscreen feels nice, you are more likely to use enough of it every day. Even then, texture depends on the whole formula, so a bemotrizinol sunscreen can still feel heavy.
Our mineral vs chemical sunscreen guide explains why you should compare finished products rather than filter types.
The fine print on kids and sprays
The FDA’s order sets conditions that other filters do not have:
- Ages 6 months and up. The order covers adults and children 6 months and older. Every US sunscreen label must say “children under 6 months of age: Ask a doctor.” The FDA’s sunscreen guidance puts shade and clothing first for babies.
- No aerosol sprays. A US bemotrizinol spray must be a pump spray or a “bag-on-valve” can, where the propellant gas never touches the sunscreen. The FDA said the data did not support mixing it directly with propellant.
- No powders. Other US filters may appear in powder sunscreens. Bemotrizinol may not. So a US powder sunscreen will not contain it.
- Children’s data is limited. The FDA said the safety data supported use from 6 months, while noting that the data in children are limited. It will keep monitoring reports.
These are US rules. Products sold in other countries follow their own.
The best sunscreen is the one you actually use
Keep the sunscreen you already use and like. Bemotrizinol matters most to people who have not found one they will wear every day. For them, it adds new textures to try.
Whatever is in the bottle, the same steps decide how well it protects you:
Step 1: Choose SPF 30 or higher with broad-spectrum (or UVA) protection.
Step 2: Apply enough. For an adult face, the American Academy of Dermatology recommends at least a teaspoon. Our sunscreen amount guide shows how to cover face, ears and neck.
Step 3: Reapply on outdoor days. Reapply at least every two hours, and sooner after swimming, sweating or drying off with a towel. A stable filter does not change this.
Step 4: Add shade, a hat, clothing and sunglasses. As Dr. Stein told the AP, “Clothing is even better.”
On outdoor days, save the amount, coverage, and reapplication checklist. It is free and needs no account.
Questions people ask
Is bemotrizinol mineral or chemical?
Chemical, or more precisely organic. It absorbs UV light, like other organic filters. It is not zinc oxide or titanium dioxide. Some products combine it with mineral filters.
Is it safer than oxybenzone or avobenzone?
The FDA found it safe and effective for its approved uses, and it was barely absorbed through the skin in testing. That is a finding about bemotrizinol, not a ranking of every other filter. Comparisons depend on the filter, the amount, and the evidence for each.
Should I throw out my current sunscreen?
No. If it is in date, you like it, and you use enough, keep using it. Sunscreen only helps when you use it.
Is it safe in pregnancy or while breastfeeding?
Public comments to the FDA pointed out that there is no information on bemotrizinol in breast milk. The FDA still concluded it is safe for its approved uses, based on how little reaches the body. If you are pregnant or breastfeeding and unsure which sunscreen to use, ask your doctor, midwife or pharmacist.
What if a new sunscreen stings or causes a rash?
Stop using it. A reaction can come from any ingredient in the formula, not only the filter. See why sunscreen stings for common causes. A rash that spreads, blisters or does not settle needs a pharmacist or doctor.
Make sunscreen a morning habit
A great filter only helps on the days you wear it. skn.coach builds a morning routine that includes a sunscreen step and reminds you at the time you choose. When you turn on location, it also takes your local UV into account. It does not measure how much protection you are getting, and it cannot test a sunscreen for you.
