A New Sunscreen Ingredient Is Coming. Is It Actually Better?

If you've ever wondered why European sunscreens seem to have more options, you're not imagining it. For more than 25 years, the U.S. list of approved sunscreen filters stayed the same. In June 2026, the FDA finally added a new one: bemotrizinol, also called BEMT or Tinosorb S.

On this episode of Facially Conscious, board-certified dermatologist Dr. Vicki Rapaport, consumer advocate Julie Falls, and esthetician Trina Renea dug into what this ingredient does, why it took so long to arrive, and the one question that matters most: Is it actually better?

What is bemotrizinol?

Bemotrizinol was developed in a Swiss lab and has been used in Europe since around 2000. Dr. Vicki described U.S. dermatologists as having lived in a "sunscreen time capsule" while the rest of the world moved ahead.

It's a broad-spectrum filter, meaning it protects against both UVA and UVB rays. Three qualities make it stand out:

• Photostability. Many sunscreen filters break down in sunlight. Bemotrizinol is extremely stable on its own, and it helps stabilize the other filters it's combined with. Because very few people reapply every two hours, a filter that holds up longer is a meaningful improvement.

• A large molecule. Only a small amount penetrates the skin. Most of it stays on the surface, where it's supposed to do its job.

• Lipophilic. It's "fat-loving," so it stays in place on the skin's natural oils and lipid barrier instead of being broken up by them — a real advantage for oilier skin.

Dr. Vicki was also candid about its limits: it doesn't cover the full UVA spectrum. No single filter does, which is why it will most likely be combined with others. Her prediction: we'll see it paired with zinc oxide.

Why did it take so long?

In the U.S., sunscreens are regulated as over-the-counter drugs, not cosmetics, and approving a new active ingredient was notoriously slow. Dr. Vicki explained that the 2020 CARES Act — the same pandemic relief law that brought stimulus checks — quietly included a reform that streamlined how the FDA reviews over-the-counter drugs like sunscreen. That change gave companies a reason to pursue approvals again.

Were American sunscreens failing? No. Dr. Vicki was clear that zinc oxide and titanium dioxide are excellent filters and that our sunscreens are "quite good." But Europe has shown there are more effective options available, and bemotrizinol appears to last longer on the skin.

Can you stop reapplying?

Trina asked the question every listener wanted answered. Dr. Vicki's answer: an ingredient doesn't determine SPF or wear time on its own. The final formula — with its preservatives, emollients, and everything else in the bottle — is what gets tested. Until we see those finished products and their results, the two-hour reapplication rule still stands.

Is bemotrizinol safe?

To earn FDA approval, bemotrizinol was reviewed for cancer risk, reproductive toxicity, irritation, and allergic reaction. It's classified as generally recognized as safe and effective (GRASE) at concentrations up to 6%. Patch testing showed no significant irritation or allergy, and it's approved for ages six months and up. For babies younger than six months, Dr. Vicki's advice is to keep them covered and in the shade rather than in the sun wearing sunscreen.

Julie asked the environmental question: Is it reef safe? Dr. Vicki explained that it was tested on coral, sea urchins, brine shrimp, and zebrafish with no significant toxicity found. It doesn't readily dissolve in water and doesn't accumulate — a very different story from oxybenzone, which Hawaii has banned.

Chemical sunscreens and cancer: separating fear from fact

Trina raised what her clients keep hearing: that chemical sunscreens cause cancer. Dr. Vicki pointed to the American Academy of Dermatology, which specifically warns against sunscreen misinformation because it leads people to wear less sunscreen and increases their skin cancer risk.

Her perspective is straightforward: UV radiation is a known carcinogen. If you're uneasy about chemical filters, choose a mineral sunscreen with zinc oxide or titanium dioxide, and cover up with clothing, a hat, and sunglasses. Skipping protection is the one choice that isn't on the table.

Why a hat alone isn't enough

From the treatment room, Trina sees this all the time: clients who believe a hat and sun-protective clothing are enough. But UV reflects off concrete, walls, and water. Your face is still exposed, even in the shade — Trina has been sunburned sitting under an umbrella in a hat and sun-protective clothing. Dr. Vicki compared it to plants that grow in the shade: they still get UV light, and so do you.

Is the SPF in your makeup enough?

Julie hears this question constantly. Dr. Vicki's answer: it's better than nothing, but how long it lasts depends on your skin and the formula. On oily skin, it can wear off within an hour. She recommended a small UV camera that clips onto a phone. When you first apply sunscreen, it shows up as dark paint on your skin, and by the afternoon you can see how much is gone. You can find it on our ShopMy page, linked at the bottom of this blog.

Julie added a point many people miss: makeup never reaches your neck, chest, hands, or arms, so you still need a dedicated sunscreen.

Trina summed up the numbers: makeup with SPF still needs reapplying, and SPF 30 to 50 is the range to aim for. Above 50, the added protection is minimal. The most important thing is that you wear it.

Preventing lip lines before they start

Dr. Vicki called the fine vertical lines around the mouth among the hardest concerns to treat — and some can never be fully erased. Her prevention tip is simple: an inexpensive SPF lip balm, applied slightly past the pink of your lips onto the surrounding skin. It isn't shiny or greasy, so no one will notice, but under a UV light, it clearly shows that the area is protected. You can find it on our ShopMy page, linked at the bottom of this blog. Genetics, smoking, drinking through straws, and puckering when you talk all play a part too.

Consumer Corner: Are Korean sunscreens better?

Trina went first: Korean sunscreens have lovely textures and feel wonderful on the skin, thanks to formulation approaches that differ from ours. But better? No. Julie finds them elegant but notes that many are lightly fragranced. Dr. Vicki, whose office holds a lunchtime Korean skincare show-and-tell almost every day, agreed: the textures are beautiful and the packaging is gorgeous, but they aren't more protective. You don't need to feel like you're missing out — affordable zinc oxide and titanium dioxide sunscreens are available right here.

Julie's final word is one we all agreed on: if you buy it, use it. Face, neck, chest, and hands. Use it up before you buy the next one.

So, is bemotrizinol actually better?

It's a genuinely good addition: highly stable, gentle on the skin, and a better environmental choice than the older filters. We're excited to test the new formulas once they reach shelves. Dr. Vicki even suggested a black-light test on air. But it doesn't replace the excellent sunscreens we already have, and it doesn't change the rules. The sunscreen that protects you is the one you wear every day and reapply.
