What is bemotrizinol and why is it a big deal for US sunscreen?

Bemotrizinol (BEMT) is a broad spectrum sunscreen ingredient that protects against both UVA and UVB rays — and it is the first new sunscreen active proposed for the U.S. market in over 25 years. Also known as PARSOL Shield, it has been used safely in Europe, Asia, and Australia for over 20 years.It is also approved for children as young as six months old.

Is bemotrizinol safe? Has it been tested?

Yes, bemotrizinol is safe. It has been used in sunscreens in Europe, Asia, and Australia for over 20 years with a strong safety record. It is also one of the most thoroughly reviewed sunscreen ingredients in the FDA's history.One of the biggest questions people have about chemical sunscreens is how much of the ingredient gets absorbed into the body. A clinical study published in Clinical and Translational Science found that even under heavy daily use, blood levels of bemotrizinol stayed well below the FDA's safety limit, with no buildup over time. Its large molecular size also means it does not penetrate skin easily.Bemotrizinol protects against both UVA and UVB rays, is minimally absorbed through the skin, and rarely causes irritation.

What does bemotrizinol do that current U.S. sunscreens can't?

Bemotrizinol is the first chemical sunscreen ingredient available in the U.S. that covers both UVA and UVB rays while also staying stable in sunlight. No currently approved US chemical filter does all three of those things at once.To understand why that matters: avobenzone is the main UVA-protective chemical filter available in U.S. sunscreens today, but it breaks down when exposed to sunlight unless stabilizing ingredients are added. Bemotrizinol does not have that problem. Studies show it retains 98.4% of its protective ability even after prolonged UV exposure. It also helps stabilize other filter ingredients around it, which gives formulators more room to create lighter, more wearable sunscreens.What this means practically: Consumers can expect lighter-weight, more cosmetically elegant sunscreens that maintain their protection level throughout the day, without needing multiple stabilizing ingredients to prop up a less stable filter.

When will I be able to buy sunscreen with bemotrizinol in the U.S.?

Sunscreens with bemotrizinol are expected to reach U.S. store shelves in late 2026. The FDA's final approval came down in June 2026, and brands need time to finish formulating and labeling their products before they can go on sale.The company that makes bemotrizinol, DSM-Firmenich, will have an 18-month head start as the exclusive U.S. supplier. That means the first products you see will all be using their version of the ingredient, sold under the name PARSOL Shield. Brands with existing international formulas may be able to launch faster than those starting from scratch.

Why has it taken so long for bemotrizinol to be approved in the U.S.?

It took over 25 years because the U.S. requires sunscreen ingredients to meet the same safety standards as over-the-counter (OTC) medicines, which is a much higher bar than most other countries apply. That process is slow, expensive, and has historically lacked a clear pathway for new ingredients.The first application for bemotrizinol was filed back in 2005, but the FDA had no formal way to process it for years. Multiple companies were stuck waiting with no response. A law called the CARES Act in 2020 finally created a workable review process, and DSM-Firmenich pushed the application through.

Is bemotrizinol a mineral or chemical sunscreen?

Bemotrizinol is a chemical sunscreen filter, but it behaves differently from any chemical filter currently approved in the U.S.Here is a quick way to think about the two types. Mineral sunscreens (zinc oxide and titanium dioxide) physically block UV rays. Chemical filters absorb UV rays and convert them to a tiny amount of heat. Most chemical filters approved in the U.S. only cover part of the UV spectrum, or they break down in sunlight and need other ingredients to stay effective. Bemotrizinol covers both UVA and UVB on its own, and it stays stable in sunlight without needing a stabilizer.It is classified at the same level as zinc oxide and titanium dioxide. No other chemical filter in the U.S. currently has that classification. It can be used on its own in a fully chemical formula or combined with mineral filters in a hybrid product.

Will bemotrizinol sunscreen leave a white cast?

No. Sunscreens with bemotrizinol will not leave a white cast. As a chemical filter, it goes on clear and blends seamlessly into all skin types.This is a big deal for a lot of people. White cast has been one of the main reasons many consumers skip mineral sunscreens or avoid them altogether, especially those with darker skin tones who have found zinc oxide and titanium dioxide formulas visible and difficult to wear daily. Dermatologists often point out that the best sunscreen is simply the one a person will actually put on every day. A lightweight, invisible option makes that a lot easier for more people.Important context: White cast is a formulation issue, not a protection issue. Sunscreens with zinc oxide and titanium dioxide remain excellent, well-studied options, particularly for sensitive skin. Bemotrizinol simply offers a new choice for those who haven't found a mineral formula that works for them.

Is bemotrizinol safe for children?

Yes. Bemotrizinol (or BEMT) is cleared for use on children six months and older. That puts it in the same category as zinc oxide and titanium dioxide. The FDA reviewed safety data across all age groups and found no concerns at the 6% concentration being approved. Clinical studies included pediatric populations.One guideline that does not change: babies under six months old should be kept out of direct sunlight and wear protective clothing rather than relying on any sunscreen product.A note for parents: Always talk to your child's pediatrician or dermatologist before introducing any new sunscreen, especially if your child has sensitive skin, eczema, or a history of skin reactions.

Does bemotrizinol affect coral reefs or the environment?

Bemotrizinol is not on any reef-restricted ingredient list and has not been identified as harmful to coral reefs.Some sunscreen ingredients, most notably oxybenzone and octinoxate, have been banned or restricted in places like Hawaii and the US Virgin Islands because of evidence they harm coral. Bemotrizinol is not among those restricted ingredients.That said, long-term environmental data for any sunscreen ingredient takes time to accumulate. If you are visiting a reef-protected area, always check the local rules, since regulations list specific restricted ingredients by name and can vary by location.

Will sunscreens with bemotrizinol replace my current sunscreen?

No. Bemotrizinol is a new option, not a replacement for what is already working. If you have a sunscreen you like and use consistently, there is no reason to change.Where it matters most is for people who have had trouble finding a sunscreen they will actually wear every day. If white cast, heavy texture, or irritation from current chemical filters has been a barrier, bemotrizinol offers something new to try. The more people find a formula that works for them, the more people wear sunscreen daily, and that is what protection actually comes down to.The basics stay the same no matter which sunscreen you choose: look for Broad Spectrum SPF 30 or higher on the label, use about 1 ounce (a shot glass full) for your whole body, and reapply every two hours when you are spending time outside.Bottom line: The best sunscreen is the one you'll use every day. Bemotrizinol gives more people a reason to say yes to that.

Is sunscreen actually toxic or are people just freaking out?

It is not toxic. Every approved sunscreen ingredient has been reviewed by medical and regulatory experts. Dermatologists, cancer researchers, and public health organizations all recommend sunscreen use for everyone.Some sunscreen ingredients are still being studied. That's scientists doing their jobs, not a red flag. Zinc oxide and titanium dioxide have passed every safety test there is. The “sunscreen is toxic” content you're seeing online is not backed by evidence. Wear it.Skin cancer is the most common cancer in the US and the risk of skipping sunscreen is documented. The risk of wearing it is not.

Why does sunscreen always break me out?

It's usually not the SPF itself, it's the formula. Some sunscreens are thick, greasy, or packed with ingredients that can clog pores or irritate your skin. Look for a lighter, non-comedogenic gel or spray. It'll probably be a lot less irritating on your face.Quick fix: Look for “non-comedogenic” or “won't clog pores” on the label. Gel and fluid textures are almost always the move for acne-prone skin.

What sunscreen actually doesn't leave a white cast on dark skin?

White cast is a common effect of mineral sunscreen, especially with zinc oxide and titanium dioxide. If that's been your struggle, go for a tinted mineral sunscreen, a micronized formula (ultra-fine mineral particles), or a chemical sunscreen that disappears into skin instead of sitting on top of it.

Can I use retinol and SPF together or will they cancel each other out?

They do not cancel each other out. They are meant to work together.Retinol builds collagen at night. UVA rays break it down during the day. SPF is the step that makes sure that work actually sticks. Apply retinol at night. In the morning, SPF goes on last, after your vitamin C, niacinamide, and moisturizer. Let each layer absorb before the next one goes on. The routine without SPF is doing half the job.The order: Cleanser → Toner → Vitamin C → Niacinamide / actives → Moisturizer → SPF (last, before makeup)

What does Broad Spectrum actually mean?

It means the sunscreen passed an FDA test confirming it covers both UVA and UVB rays. It is the most important thing on the bottle.SPF alone only measures UVB, the burn ray. UVA is the ray that breaks down collagen, penetrates glass, and causes long-term skin aging without any visible sunburn. UVA makes up about 95% of UV radiation reaching your skin every day. “Broad Spectrum” is the only label that confirms you are covered for both.The SPF number tells you burn protection. Broad Spectrum tells you aging protection. You need both. Check for both.

Is mineral sunscreen actually safer or is that just clean beauty marketing?

Here is the honest version.Both mineral and non-mineral sunscreens have been thoroughly tested and proven to help prevent skin cancer and other sun damage. Both work when labeled Broad Spectrum SPF 30 or higher and dermatologists still recommend them for daily use. You can feel confident using either one.The best sunscreen is the one you'll actually wear every day.

Do I need sunscreen if I'm inside most of the day?

Yes, if you are near a window. UVA rays pass straight through glass.UVB, the burn ray, is mostly blocked by windows. UVA is not. If you sit near natural light at home or work, you are getting UVA exposure without any visible sign of it. That is the ray that breaks down collagen and drives long-term skin aging. No sunburn means no warning.If you are genuinely in a windowless space all day the risk is lower, but the daily habit is worth building regardless. It takes ten seconds.Up to 80% of UV rays can penetrate through clouds too. Cloudy day SPF is not optional if you are spending time outside.

Where does sunscreen go in my skincare routine, and will it ruin everything if I put it on?

Last. Sunscreen goes on after your skincare and before makeup. It also won't mess with your actives.SPF needs to form a continuous layer on your skin to work. Applying other products over it breaks that layer up. Your vitamin C, retinol, and niacinamide all do their jobs underneath it. Think of SPF as the step that protects everything above it from being undone by UV. Every product in your routine is working against daily UVA exposure the moment you skip it.The routine without SPF is a leaky bucket. You are investing in your skin every morning. SPF is the step that makes that investment actually hold.

Frequently Asked Questions

What is Bemotrizinol, and why did it take 25 years to get here?

‍Bemotrizinol (also called BEMT or PARSOL Shield) is a broad spectrum sunscreen ingredient that has been used safely in Europe, Asia, and Australia for over 20 years. The US Food and Drug Administration (FDA) recently approved it as the first new sunscreen ingredient available in the United States in more than 25 years.

So why did this take so long?

The U.S. regulates sunscreen ingredients as over-the-counter (OTC) medicines, not as cosmetics, because they make health claims (e.g., preventing sunburn and reducing skin cancer risk). This ensures a high standard of safety and effectiveness but makes adding new sunscreen ingredients slower and more complex than in other parts of the world. That’s why the approval of bemotrizinol (a new UV filter) is such a milestone!

Is bemotrizinol safe?

Yes. Bemotrizinol is safe and has been used worldwide for over 20 years. The FDA recently reviewed the evidence supporting its safety and effectiveness and classified it as GRASE (Generally Recognized as Safe and Effective), which is the same top-tier safety classification as zinc oxide and titanium dioxide.

While bemotrizinol shares some of the consumer-friendly qualities people look for in mineral sunscreens, it is a distinct UV filter with a clear, non-whitening finish and low skin penetration.

One of the most common concerns people have about sunscreen ingredients is whether they get absorbed into the body. Bemotrizinol’s large molecular size helps limit absorption, and it is also a broad-spectrum UV filter that protects against both UVA and UVB rays. The addition of this filter to sunscreen products can offer enhanced sun protection, but will not necessarily replace the trusted sunscreens already on the market.

On the Bigger Sunscreen Safety Conversation: You may have seen content online claiming sunscreen is harmful. There is no scientific evidence that proves these claims. Excessive sun exposure is known to cause skin cancer, the most common cancer in the United States, and health authorities consistently emphasize that daily use of broad-spectrum sunscreen—along with other protective measures—can significantly reduce the risk of skin damage and skin cancer.

Important Update: Acetaminophen

There’s been a lot of talk recently about misleading claims that taking acetaminophen during pregnancy can cause autism. We’ve pulled together some FAQs and answers to help families.

How does bemotrizinol work?

Think of bemotrizinol like a highly efficient “UV shield." It captures and neutralizes both UVA aging and UVB burning rays at the skin’s surface before they can do damage, and it keeps working even in strong sunlight. It also helps stabilize other sunscreen ingredients and boost overall SPF performance when used in combination with other UV filters (or sunscreen active ingredients).

A NOTE ABOUT DYE-FREE PRODUCTS: Dye-free medications and supplements are a great option for individuals who prefer or require products without dyes, such as those with allergies, sensitivities, or personal preferences. Importantly, both dye-containing and dye-free options are held to the same rigorous safety and quality standards. If you’re unsure which is right for you or your family, talk to your pharmacist or healthcare provider. They can help you choose the option that best suits your needs.

Who will benefit most from bemotrizinol?

Bemotrizinol is a brand-new option for everyone. Given how it works, it could be helpful for certain groups of people.

The "I've avoided using sunscreen because of white cast" crowd.

The visible white or gray film that some mineral sunscreens leave on skin is known as a “white cast”. It’s not a small annoyance, and it is not something every newer formula has solved. The white cast especially affects people with darker skin tones, who often find that mineral sunscreens are not cosmetically acceptable for daily wear.

Bemotrizinol is designed to be invisible on skin, going on completely clear regardless of skin tone. Dermatologists often say the best sunscreen is the one you will actually use every day, and for a lot of people, a noticeable white cast is the reason they do not regularly apply sunscreen. Bemotrizinol removes that barrier while offering broad-spectrum protection with the same top safety rating as zinc oxide and titanium dioxide.

For Kids and Families

Bemotrizinol is approved for children six months and older, giving parents another option to consider when choosing a sunscreen for their kids. For parents who have struggled to find a sunscreen their child will actually wear, more options mean more chances to find the right fit.

One thing the FDA is clear on: babies under six months old should still be kept out of direct sunlight rather than relying on any sunscreen. Instead, infants should be kept out of direct sunlight and protected with shade and protective clothing. As always, your dermatologist or pediatrician is the best resource for questions about sun protection for your child.

On Reef Safety: Bemotrizinol has a favorable environmental profile and does not easily degrade in the environment, making it a good option for those concerned about the potential ecological impact of personal care products.

When will bemotrizinol hit U.S. shelves?

Sunscreens with bemotrizinol are expected to reach U.S. store shelves in late 2026. When products do show up, here is what to look for on the label:

The active ingredient list will say bemotrizinol (you may also see it referenced elsewhere on the packaging as PARSOL Shield, the brand name used by the ingredient's manufacturer).

A Note on Your Current Sunscreen: The best sunscreen is the one you will use every day. Bemotrizinol simply adds a new option to help you maintain that routine. The basics never change:

The product will include a claim of “Broad Spectrum” (this protects against UVA and UVB rays), with an SPF of 30 or higher.
Use broad-spectrum SPF 30 or higher, apply about 1 ounce (a full shot glass) to any areas of your face and body that areexposed.
Reapply every two hours when you are outside (more often if you've been swimming, sweating a lot, or toweling off).
Seek shade, especially between 10 AM and 4 PM when UV rays are strongest.
Wear protective clothing like long-sleeved, breathable shirts, skirts or pants, a wide-brimmed hat, UV-blocking sunglasses, or clothing with an ultraviolet protection factor (UPF) of 50.

What is fluoride?

Fluoride is a natural mineral found in water, soil, and some foods. It strengthens your enamel, repairs early signs of damage, and makes teeth more resistant to acids from bacteria and sugar.

Is fluoride toothpaste still the most effective option, or are fluoride-free formulas just as good?

Fluoride is still the gold standard for cavity protection. Fluoride-free options can clean your teeth, but they don’t offer the same enamel-strengthening power.

Is fluoride safe for daily use?

Yes. When used as directed, fluoride is safe and effective. It’s been trusted and recommended by major health organizations for over 70 years.

How does fluoride actually protect teeth?

It strengthens enamel, repairs early signs of decay through remineralization, and makes teeth more resistant to acids from bacteria and sugary foods.

Are there any risks to using fluoride long-term?

The main risk—especially for young kids—is swallowing too much, which can lead to mild fluorosis (faint white streaks on teeth). Using the right amount prevents this. For parents, supervise brushing to ensure kids spit out the toothpaste and don't swallow it. 

At what age should kids start using fluoride toothpaste?

As soon as the first tooth appears!

* Under 3 years: a tiny rice-sized smear
* Ages 3–6+: a pea-sized amount
‍
Supervise brushing so they don’t swallow it.

Is fluoride still safe and recommended for kids with all the claims online?

Yes. A lot of online claims can be confusing, but decades of research show fluoride is safe and strongly recommended for cavity prevention when used properly.

How much fluoride should my child get from toothpaste?

Use age-appropriate amounts and brush twice a day. If your water isn’t fluoridated, ask your dentist about additional options.

How do I know which kids’ toothpaste claims are real and not just marketing?

Check for the ADA Seal of Acceptance and choose brands your dentist recommends.

Do fluoride-free or “natural” toothpastes protect kids from cavities?

They can help clean teeth, but they don’t provide the same cavity protection as fluoride toothpastes.

Are fluoride-free toothpastes just as effective for adults?

Not for cavity prevention. Fluoride-free toothpastes can help with cleaning and freshening breath, but they do not protect against cavities the way fluoride does. For adults, or anyone who is prone to cavities, fluoride toothpaste remains the most effective option for preventing tooth decay.

Do fluoride alternatives like nano-hydroxyapatite (nHAp) make a difference?

Yes—nHAp can help with sensitivity and early enamel repair. But it hasn’t matched fluoride’s cavity-prevention strength in studies.

How do I compare fluoride vs. fluoride-free options if I have sensitivity or enamel wear?

Fluoride is best for strengthening enamel and cavity prevention. nHAp may help with sensitivity and enamel repair. Some people benefit from using both in a balanced routine. Talk to your dentist about what's right for your specific needs.

Are whitening toothpastes safe to use with fluoride or fluoride-free products?

Most are safe but can be abrasive. Choose gentle formulas and avoid using them every single day—especially for kids.

What should I look for when choosing an OTC toothpaste?

Pick products with proven active ingredients (like fluoride), check for the ADA Seal of Acceptance, and avoid unnecessary additives or sweeteners.

Does fluoride affect hormones or the brain?

No credible scientific evidence shows fluoride at levels used in toothpaste or properly fluoridated water (0.7 mg/L) disrupts hormones or causes neurodevelopmental harm.

What should I do if my community stops adding fluoride to the water?

Use fluoridated toothpaste, consider fluoride rinses (for ages 6+), and talk to a dentist about fluoride supplements for kids (if needed).

Do fluoride supplements have side effects?

They’re safe when used under dental guidance and typically recommended for children in areas without fluoridated water or at high risk for cavities.

What’s the best way to make sure I’m getting enough fluoride?

Brush twice daily with fluoride toothpaste, drink fluoridated tap water if available, and ask your dentist for personalized advice if you’re cavity-prone.

Are heavy metals in supplements dangerous?

In the amounts typically found in supplements, no. Trace levels of lead, cadmium, arsenic, and mercury enter the food supply from both natural sources and human activity, and they end up in many everyday foods as well. Risk depends on how much you take in and over how long. For most metals, health agencies set limits with wide safety cushions. For lead, no amount has been shown to be safe, so the goal is to keep exposure as low as possible. Extra care is reasonable for children and people who are pregnant, which is why guidance for those groups is set especially conservatively.

Why do plant-based protein powders tend to have more heavy metals than whey protein?

Plant-based proteins come from crops like peas and rice that absorb trace metals from soil as they grow. When concentrated into powder, those traces concentrate too. Whey comes from milk, which goes through a different biological process and shows lower heavy metal levels. This reflects a difference in source material, not a safety problem.

Is there a safe level of lead in supplements?

No known safe level of lead has been identified, so the goal is to keep exposure as low as possible. Since lead builds up in the body over time, extra care is appropriate for children and people who are pregnant. Safety limits for these groups are set very conservatively. Manufacturers are required to test their products for heavy metals, and some go a step further with independent third-party testing. Consumers can contact manufacturers directly to ask about their testing practices.

Is it safe to eat fish if it contains mercury?

Yes. Since seafood is the main source of mercury exposure, health experts, including the FDA and the Environmental Protection Agency (EPA), provide guidance to help everyone make safe and healthy choices. This advice is especially useful for people who are pregnant, breastfeeding, or feeding young children, to help them pick fish that are both nutritious and lower in mercury—such as salmon, tilapia, shrimp, and canned light tuna.

Does the FDA regulate heavy metals in supplements?

Yes, the FDA has authority over dietary supplements and can take action when a product is unsafe. For example, the FDA uses Interim Reference Levels (IRLs) for lead as benchmarks to evaluate potential health risks in food and dietary supplements.

What does a Prop 65 warning on a supplement label actually mean?

It means the product contains a listed substance above California's disclosure threshold. It is a legal notification requirement, not a safety verdict. Prop 65 thresholds are set conservatively, often 1,000 times below any level linked to observed harm. It does not mean the product violates federal safety standards.

Are organic supplements lower in heavy metals?

Not necessarily. Organic certification covers things like pesticides and fertilizers, but it doesn't control what's naturally in the soil or how a product is made. An organic plant grown in soil with arsenic or cadmium will still absorb those metals. Organic is a good farming standard, but it is not a reliable sign of lower heavy metal levels.

How do I know if my supplement has been tested for heavy metals?

By law, supplement manufacturers are required to test or verify that their products meet quality and safety specifications, including limits on contaminants such as heavy metals when appropriate. The FDA reviews these records during inspections. Some companies go a step further and use independent third-party re-testing for added assurance. You can always contact the manufacturer directly to ask about their testing and quality practices.

Should children or pregnant people avoid supplements because of heavy metals?

Not automatically, but extra care is reasonable. Safety guidelines for these groups are set very carefully because their bodies can be more sensitive to certain exposures. For lead in particular, where no amount has been shown to be safe, the goal is always to keep exposure as low as possible. Children and pregnant individuals should take only supplements recommended by a healthcare provider.

What should I look for when buying a supplement I can trust?

Start with established brands sold through reputable retailers, not unverified online sellers. Be skeptical of claims like "pure" or "heavy metal free" unless there is independent testing to back them up. When in doubt, don't hesitate to contact the manufacturer directly to ask for their heavy metals test results.
