Give your skin the upgrade it deserves…finally! For the first time in over 20 years, US sunscreens can add a new active ingredient. Bemotrizinol is a UV filter long used in Europe and Asia for strong UVA and UVB protection. Now, bemotrizinol is approved as a sunscreen active ingredient by the FDA for use in the US. [1] We usually steer people toward mineral sunscreens first, but if bemotrizinol continues to look as safe as early data suggests, it could be a standout choice among chemical sunscreens. This UV blocker remains stable in sunlight and shows low skin absorption in FDA‑reviewed studies, making it an attractive option for anyone who cares about both safety and effectiveness [2]. Swap out sunscreens that have harmful chemicals for safer options. Here’s what you need to know about bemotrizinol in sunscreen.
What Is Bemotrizinol?
Could hormone-conscious sun-worshippers finally get the protection they need without whitecast? Things are looking promising now that the FDA has approved the use of bemotrizinol in sun care products.
Bemotrizinol is a broad-spectrum UV-filtering chemical. That means bemotrizinol helps protect the skin by absorbing ultraviolet radiation before it can damage skin cells.
You may see this ingredient referred to by a few different names on sunscreen packaging, including:
-
Bemotrizinol (pharmaceutical chemical name)
-
BEMT (abbreviated)
-
Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (full chemical/INCI name)
-
Tinosorb S (ingredient brand name)
-
Parsol Shield (ingredient brand name)
BEMT could be a big win for people who want sunscreen that works hard without leaning on some of the more controversial older filters. It delivers strong, stable UVA and UVB protection with early data suggesting low absorption into the body. Next, we’ll unpack why that matters for safety, skin feel, and the kinds of formulas you’ll start seeing in the US.
Why Sunscreen Innovation Matters
Fun in the sun is that much more fun when done safely. While sunscreen is essential for most Americans, a majority of suncare products contain harmful chemicals, including oxybenzone, homosalate, octinoxate, and more. These chemicals can disrupt hormones, interfering with health and fertility [3].
Soak up Vitamin D, not hormone-disrupting chemicals. Using safer sunscreens regularly can help reduce the risk of sunburn, premature skin aging, dark spots, and skin cancer. Unfortunately, anyone who has tried to find a mineral sunscreen they actually want to wear knows the struggle is real.
Some formulas feel greasy. Some leave a white cast. Some sting around the eyes. These qualities are enough for millions of people to use chemical sunscreens or no sunscreen at all.
That is where bemotrizinol could make a real difference. With FDA approval, bemotrizonol gives formulators another tool to create sunscreens that are more protective, more stable, and hopefully more pleasant to wear.
Bemotrizinol Chemical vs. Mineral Sunscreen
Feel good about your sun safety routine with safer sunscreen products. At Million Marker, we base our sunscreen recommendations on the best available science, and we update them as new research emerges.
Currently, we generally recommend mineral sunscreens made with non-nano zinc oxide or non-nano titanium dioxide. That’s because these mineral ingredients remain on the skin's surface and have very little absorption into the body.
That said, they are not perfect. Many people find mineral sunscreens thick, greasy, and difficult to rub in. They’re also prone to leaving a whitecast.
If a sunscreen doesn't feel good to wear, there's a good chance it won't get used consistently, and the best sunscreen is ultimately the one you'll wear every day.
No Whitecast
Mineral sunscreens can leave a whitecast because they use tiny mineral particles that sit on top of the skin. These UV filters physically reflect light, but can look chalky or streaky.

Bemotrizinol works differently. It is a chemical UV filter that blends into the formula and absorbs UV rays rather than scattering visible light. Therefore, BEMT goes on clear rather than leaving a visible layer.
This chemical UV filter also dissolves into the lotion or gel base rather than sitting on the surface like pigment. Therefore, products containing bemotrizinol are much more likely to appear sheer and feel invisible on the skin when rubbed in well.
Low Absorption
BEMT could help bridge the gap between a seamless experience, sun safety, and overall health. Many of the common chemical UV filters commonly found in US sunscreens have been shown to absorb into the bloodstream.
Alarmingly, some studies have detected levels above the FDA's threshold for additional safety testing. While this doesn't necessarily mean they are unsafe, it has prompted ongoing research into their long-term health effects, including potential impacts on hormones and other biological systems.
Bemotrizinol is a chemical sunscreen that doesn’t seem to leave as lasting an impression as its counterparts. In FDA-reviewed studies, participants applied sunscreen containing bemotrizinol four times a day over most of their bodies for several days.
Nearly 70% of blood samples contained no measurable BEMT. Even more promising, only about 3% exceeded the FDA's 0.5 ng/mL threshold that typically triggers additional toxicology review [2].
Broad-Spectrum Protection
One of the biggest reasons why sun lovers and experts alike are excited about BEMT is that it provides excellent broad-spectrum protection. This chemical can shield your skin from both UVA and UVB rays.

UVB rays are the primary cause of sunburn and play a major role in skin cancer. UVA rays penetrate deeper into the skin, where they contribute to premature aging, wrinkles, dark spots, and also increase the risk of skin cancer. Since UVA rays account for about 95% of the UV radiation reaching Earth's surface, protecting against both types of UV light is essential.
Unlike many older UV filters that primarily block either UVA or UVB, bemotrizinol covers a wide range of the UV spectrum. This allows sunscreen formulators to build more balanced products that offer stronger overall protection.
Long-Lasting
One of the biggest pains about applying sunscreen is reapplying sunscreen. Bemotrizinol is highly photostable, meaning it doesn't easily break down in sunlight. That helps sunscreen maintain its protection throughout the day and makes it an excellent partner for other UV filters in broad-spectrum, high-SPF formulas. Even so, regular reapplication is still recommended to maintain protection after sweating, swimming, or towel‑drying.
Why FDA Approving Bemotizinol Is A Big Deal
The USA has gone decades without approving any new active ingredients for sunscreen. This void has left Americans with a relatively short list of UV filters compared with Europe and other regions. In that time, several existing UV filters have raised questions, including avobenzone, homosalate, and oxybenzone.

These chemicals have been suspected of disrupting hormones, even though they’re generally recognized as safe when used as recommended on packaging. The problem is that some people apply more sunscreen than others, which can make measuring safety for everyone challenging.
Plus, these recommendations don’t take into account the total effects of all the products we use. The average adult uses approximately 12 personal care products daily. Many of these products can contain UV filters, including lotions and lip balm. Even clothing can contain UV-filtering chemicals.
Having a new broad-spectrum sunscreen ingredient can help limit the toxic burden of multiple personal care products. By making it readily available in the United States, top brands are more inclined to add this safer ingredient to their products.
Is Bemotrizinol Safe?
If you pay attention to the ingredients in your sunscreen, it’s natural to wonder where bemotrizinol is safe. Current science seems to support that BEMT has one of the strongest safety profiles we've seen among chemical UV filters.
The FDA determined it is generally recognized as safe and effective (GRASE) for adults and children 6 months and older at concentrations up to 6%. Experts are encouraged by its low absorption rate in humans.
When Will Sunscreen with BEMT Be Available?
The FDA approval of BEMT is a step forward, but don’t toss out your mineral sunscreens just yet! US companies can sell sunscreen with bemotrizinol starting August 9, 2026. However, that doesn’t mean they will be available right away. Companies still need to develop these products. It’s expected that brands will roll out BEMT sunscreens starting in late summer, early autumn 2026.
As of now, only DSM-Firmenich will supply BEMT under the brand name Parsol® Shield for the first 18 months [4]. After that, Tinosorb S and other suppliers could enter the US market. This will open the door for many options that could be safer than current sunscreen products.
Things to Look Out for When Shopping for Sunscreen with Bemotrizinol
Seeing BEMT on a sunscreen label is a great start for selecting a safer product, but it doesn’t mean that you’re in the clear yet. Sunscreens are complex formulas made with dozens of ingredients, including preservatives, fragrances, solvents, moisturizers, and other UV filters.
While bemotrizinol has a reassuring safety profile, the overall safety and quality of a sunscreen depend on the entire ingredient list, not just a single active ingredient. If you're trying to choose a healthier sunscreen, look beyond the front of the bottle.
Check the ingredient list for other UV filters, added fragrances, preservatives, or ingredients you may prefer to avoid based on your personal needs. If you're not sure where to start, the Million Marker Product Guide can help you enjoy fun in the sun safely.
At-Home Test for Oxybenzone
As we’ve mentioned, oxybenzone is a common UV filter used in everyday products. Repeated exposure to oxybenzone could disrupt your hormones, which can impact your health and fertility.
If you're curious about your personal exposure to oxybenzone, Million Marker can help provide a clearer picture. Our at-home urine test measures oxybenzone and other environmental chemicals to show what is actually present in your body…not just what may be listed on a product label.
Your results include personalized insights and practical recommendations to help you identify potential sources of exposure and make informed choices to reduce them. Whether you're evaluating your sunscreen routine or simply interested in understanding your exposome, testing gives you data that's specific to you. Learn what’s inside with Million Marker.
