- Bemotrizinol is the first new sunscreen active ingredient allowed in the U.S. in more than 25 years. The U.S. Food and Drug Administration (FDA) added it to the sunscreen rules in June 2026, and the first products reached U.S. shelves in the fall.
- One filter covers both UVA and UVB. It absorbs across the whole UV range, keeps its strength in sunlight, and leaves no white cast, which is why European sunscreens have used it since 1999.
- You don’t have to switch. A broad-spectrum SPF 30 or higher that you apply generously and reapply on time is still doing its job, whatever filters are inside it.
- It helps most if mineral formulas never worked for you. People who skip zinc oxide because of the white cast, or whose current sunscreen stings or breaks down quickly, have the most to gain.
- Look for it on the back of the package. ‘Bemotrizinol’ appears in the active ingredients at up to 6%, and the product still needs to say ‘Broad Spectrum’ and SPF 30 or higher.
If you follow sunscreen news, this is the one people have been waiting on for a long time. For years, some of the best UVA filters available were sold only in European and Korean sunscreens, and the list of filters allowed in the U.S. stayed the same.
That changed this year, and the first bottles are now on U.S. shelves. With bemotrizinol here, the questions are practical: is it worth switching, how do you find it on a label, and is the sunscreen you already own somehow worse?
What Is Bemotrizinol?
Bemotrizinol is a chemical sunscreen filter (chemists call these organic filters, meaning carbon-based, not natural) that absorbs both UVA and UVB rays on its own, and in June 2026 the FDA made it the first new sunscreen active ingredient permitted in the U.S. since the 1990s. It has been sold in Europe since 1999 as Tinosorb S and Parsol Shield, has decades of use across Australia, Canada, and much of Asia, and it is common in the Korean and Japanese sunscreens that many U.S. shoppers have ordered online for years because the same filters weren’t sold here.
What sets it apart is how much of the UV spectrum it covers. Most sunscreen filters are strong against either UVA or UVB, not both. UVB is the burning ray and the one the SPF number measures; UVA reaches deeper, drives visible aging, and adds to skin cancer risk, and because it doesn’t burn, you don’t notice it happening.
U.S. formulas have had to combine several filters to cover both. Bemotrizinol covers both in one ingredient, absorbing across UVB (280–315 nanometers) and the full UVA range out to 400 nanometers, where the older U.S. filters stopped around 370. Its two absorption peaks sit at 310 and 340 nanometers, one in each band, which is why Stanford Medicine dermatologists call it the best broad-spectrum UV filter available. And it keeps its strength in sunlight, while avobenzone, the usual UVA filter in U.S. formulas, is weakened by sunlight itself within a couple of hours unless the formula is built to protect it.
Under the FDA’s final order, bemotrizinol can make up to 6% of a formula, in lotions, creams, gels, sticks, and pump sprays, for adults and children six months and older. Because the FDA regulates sunscreen as an over-the-counter drug, a product with the new filter still has to meet every other sunscreen rule, from the SPF test to the water-resistance claim.
Why It Took So Long to Reach the U.S.
The delay was about paperwork, not doubt. In the E.U., sunscreen is a cosmetic, so a new filter can be cleared in a few years. In the U.S., every sunscreen active ingredient has to be added to the FDA’s drug rulebook, and for decades there was no workable path. The E.U. list grew to roughly 30 filters while the U.S. list stalled at about half that, a gap that comes from the drug-versus-cosmetic split.
A 2020 law created a request process; the manufacturer, DSM, filed in September 2024, sales were allowed from August 9, 2026, and by mid-October the first bottles were in U.S. drugstores, as the Associated Press reported. Expect the lineup to grow slowly: the manufacturer holds 18 months of exclusivity from that August date, so only a handful of products will carry it until early 2028. And the other European filters people ask about, Tinosorb M and Mexoryl, are still not allowed in the U.S.
How Bemotrizinol Compares With the Filters You Already Use
Bemotrizinol doesn’t make the older U.S. filters bad; they protect skin the same way they did last year. What changes is the tradeoffs a formulator has to make, and that is the part you feel on your face. The U.S. list now has 17 filters on paper, several of them rarely used. Here is how the ones you are likely to see on a label compare:
| Filter | Covers | Holds up in sunlight | Finish on skin |
|---|---|---|---|
| Zinc oxide (mineral) | UVA and UVB | Yes | Can leave a white cast |
| Titanium dioxide (mineral) | UVB and some UVA | Yes | Can leave a white cast |
| Avobenzone (chemical) | UVA | Weakened by sunlight itself unless the formula protects it | Clear |
| Octocrylene (chemical) | UVB and some UVA | Yes, and it helps protect avobenzone | Clear |
| Homosalate and octisalate (chemical) | UVB | Yes | Clear |
| Octinoxate (chemical) | UVB | Loses some strength in sunlight | Clear |
| Oxybenzone (chemical) | UVB and some UVA | Yes | Clear |
| Bemotrizinol (chemical) | UVA and UVB | Yes, and it helps protect avobenzone | Clear |
Mineral sunscreens already cover both rays, but the cast keeps many people, deeper skin tones especially, from wearing them. Clear chemical formulas felt better but leaned on avobenzone, which sunlight itself weakens unless the formula is built to protect it. Bemotrizinol gives you a clear formula with UVA protection that holds, usually alongside other filters, since 6% on its own isn’t enough for a high SPF. And because the filter holds up on its own, formulas can lean less on the stabilizers and heavy oils that make some sunscreens feel greasy.
Should You Switch to a Bemotrizinol Sunscreen?
It depends. If you already use a broad-spectrum SPF 30 or higher, put on enough of it, and reapply every two hours, your protection is already real. The sunscreen that gets applied every day beats the one with the newest ingredient sitting in a drawer. Switching makes sense in a few situations:
- Mineral sunscreen never worked for you. If zinc oxide leaves a cast you can’t wear, bemotrizinol covers both rays without it.
- Your current formula stings or fades. Avobenzone products can irritate eyes and lose UVA strength through the afternoon; a filter that holds its strength addresses both.
- You want stronger UVA coverage without importing. The same filter people ordered from Europe and Korea is now in formulas made for the U.S. rules.
- You have reactive skin. Bemotrizinol is a large molecule, so it mostly stays on the skin’s surface rather than crossing the skin barrier, and the FDA-reviewed testing at the 6% concentration found no concerning irritation, though U.S. experience is only months old.
For some people it changes nothing. Babies under six months still get shade and clothing, not sunscreen, and anyone happy with a mineral formula has no reason to move. If you skip sunscreen because of how it feels, you have a new option worth trying, but a UPF layer over the arms and torso solves more of that problem than any filter can.
How to Spot Bemotrizinol on a Label
Turn the package over. U.S. sunscreens list their filters under ‘Active ingredients’ in the Drug Facts panel, and bemotrizinol appears there by that name with a percentage, up to 6%. A lower percentage isn’t a weaker product; the SPF is tested on the whole formula. The front may say ‘new’ or ‘advanced UVA protection’, but the back is where the tested claims live.
Two other things still have to be there. ‘Broad Spectrum’ means the finished product passed the FDA’s UVA test, and an SPF of 30 or higher is the daily baseline dermatologists recommend. A new filter doesn’t exempt a product from either, and the tested claims are the ones to shop by.
On an imported product, the same ingredient goes by its chemical name, bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT), or by the brand names Tinosorb S and Parsol Shield, often at up to 10%, the E.U. limit. Those products weren’t reviewed by the FDA, which doesn’t make them unsafe; it means their SPF and water-resistance claims were tested to another country’s rules.
In practice: Check three things on the back: the active ingredients, the words ‘Broad Spectrum’, and an SPF of 30 or higher. If those check out, the rest of the label is preference.
What a New Filter Doesn’t Change
A better ingredient doesn’t rewrite the habits that make sunscreen work: about one ounce for a full body, a fresh coat every two hours, and another after swimming or heavy sweating. It also doesn’t settle the reef question. Bemotrizinol isn’t named in the Hawaii or Palau bans and isn’t on the lists of filters linked to coral harm, but it hasn’t been studied in the water long enough to be called safe for it either.
And it doesn’t change the math on clothing. A UPF 50+ shirt blocks at least 98% of UVA and UVB on the skin it covers, with no filter choice to make and nothing to reapply. That is the logic behind what we make at Essuntials®: natural-blend fabrics with mineral UV protection built into the fibers, and independently lab-tested and verified to hold UPF 50+ through at least 40 washes. The sunscreen decision then only has to cover the exposed areas like your face, neck, and hands.
Frequently Asked Questions About Bemotrizinol
Here are answers to the most common questions about bemotrizinol.
Is bemotrizinol the same thing as Tinosorb S?
Yes, they are the same ingredient. Bemotrizinol is its official U.S. name; Tinosorb S and Parsol Shield are trade names, and bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) is the chemical name on imported ingredient lists.
Is bemotrizinol a chemical or a mineral sunscreen?
It is a chemical filter, which chemists call organic because it is carbon-based, not because it is natural. Like other chemical filters it absorbs UV energy and releases it as a small amount of heat, but unlike most it covers UVA and UVB in a single molecule. Mineral filters, zinc oxide and titanium dioxide, mostly absorb UV too and reflect and scatter a smaller share.
Is bemotrizinol safe for kids?
The FDA’s order covers children six months and older, like every other sunscreen filter. Younger babies still get shade, a UPF hat, and clothing rather than sunscreen. For older kids the usual routine applies: UPF clothing as the base, sunscreen on what it doesn’t cover.
Does bemotrizinol replace avobenzone?
It doesn’t replace avobenzone in U.S. products, at least for now. At the 6% limit it isn’t strong enough alone to reach a high SPF, so manufacturers pair it with avobenzone, octocrylene, or zinc oxide. The pairing has a bonus: bemotrizinol helps avobenzone hold its strength, so the formula’s UVA protection lasts longer.
Is my old sunscreen worse now?
Your old sunscreen protects exactly as well as it did last year, as long as it hasn’t expired. A broad-spectrum SPF 30 or higher that you use properly works the same way it did before June 2026. The new ingredient adds a choice, mainly for people who couldn’t find a formula they would wear daily.
Is bemotrizinol reef-safe?
No one can say yet. It isn’t named in the Hawaii or Palau restrictions or on the lists of filters tied to coral damage, but long-term marine studies don’t exist. If reef impact is your main concern, a UPF shirt in the water means far less sunscreen to apply.
Can I keep using the European or Korean sunscreen I import?
You can, with the same caveat: its claims were tested to another country’s rules, not reviewed by the FDA. The difference now is that you no longer have to import to get this filter; U.S.-made formulas with bemotrizinol are tested to the FDA’s SPF, broad-spectrum, and water-resistance standards.
The Essential Takeaway: A Better Option, Not a Mandatory Upgrade
Bemotrizinol gives U.S. shoppers something many have ordered from overseas for years: a clear filter that covers UVA and UVB in one ingredient and keeps its strength in the sun. If mineral sunscreen never suited you, or your current formula stings or stops working well before it is time to reapply, it is worth a try.
If your sunscreen already goes on every morning and gets reapplied, keep using it. The best sun protection is the kind you can live in, and the filter in the bottle matters less than the habit of putting it on.
