5 Questions Dermatology Patients May Have About Newly-Approved Bemotrizinol

On June 9, 2026, the FDA approved bemotrizinol as a permitted active ingredient in over-the-counter (OTC) sunscreen products—the first addition to the FDA’s sunscreen monograph in more than 20 years and the first new chemical ultraviolet (UV) filter to receive a Generally Recognized as Safe and Effective (GRASE) designation in the US.^1,2 As newer sunscreens come to market later this year and patients come to the clinic armed with questions, here is what American physicians and health care professionals should know about the UV filter the rest of the world has relied on for more than 20 years.

1. “Is Bemotrizinol Reef-Safe?”

It’s a fair question, especially for patients who spend time in the ocean. Oxybenzone and octinoxate, 2 widely used chemical UV filters, have been linked to coral bleaching and harm to marine ecosystems, prompting outright bans in places like Hawaii, Key West, and Palau.³

Bemotrizinol—also sold under the abbreviation BEMT and the brand name Parsol Shield in the US—has not been linked to coral bleaching or disruption of marine life, and early data suggest it does not bioaccumulate in marine environments. Even so, long-term ocean safety data for bemotrizinol are still limited, and the term “reef-safe” has no regulated or standardized meaning in the US. Dermatologists and other health care professionals may want to proactively address reef safety with patients who spend time in coastal or aquatic environments, particularly as environmental research on newer filters continues to evolve.

2. “How Will It Interact With My Skin?”

Bemotrizinol was designed in the late 1990s as a large, stable molecule—and that size matters. With a molecular weight of 627.8 g/mol, it tends to stay on the skin’s surface rather than passing through into the bloodstream, which sets it apart from several currently approved chemical filters.⁴

The FDA’s review found that bemotrizinol showed low levels of skin absorption and rarely caused irritation.² In vitro studies also showed no estrogenic activity—a concern that has been raised with older filters like oxybenzone. People with sensitive skin, a history of sunscreen-related contact dermatitis, or conditions such as rosacea or atopic dermatitis may tolerate bemotrizinol better than products containing octinoxate or octisalate, both of which have been associated with allergic reactions. Patch testing before regular use is still a good idea with any new topical product.

There is a cosmetic upside as well: bemotrizinol leaves no white cast and feels lighter and less greasy than many existing filters—a practical benefit for patients who have struggled with adherence and particularly for those with darker skin tones who have found mineral sunscreens difficult to wear.⁵

3. “Is It Safe for Children or Everyday Use?”

Yes, and the approval covers a wider age range than many patients may expect. The FDA cleared bemotrizinol for use in adults and in children as young as 6 months old, making it the first chemical UV filter to receive an explicit GRASE designation for use in children as young as 6 months old.¹ That determination drew on a 2-year animal carcinogenicity study, which found no cancer-causing effects from topical application, and a multigenerational reproductive study that showed no harm to reproductive outcomes or offspring.²

Products will carry bemotrizinol at concentrations up to 6%. One practical advantage worth noting: bemotrizinol is highly photostable, retaining more than 90% of its protective capacity after extended sun exposure in testing, which means protection holds up better between reapplications than it does with less stable filters.⁶ Standard reapplication guidance still applies—broad-spectrum SPF 30 or higher, every 2 hours outdoors, and more often when swimming or sweating.

4. “If the EU Has Been Using It for So Long, Why Is the US Just Now Approving It?”

Bemotrizinol has been in use across the European Union (EU) since 2000 and has been available in Australia, parts of Asia, and Latin America for years. The gap came down to how the US and EU classify sunscreen differently.⁷

The EU treats sunscreen as a cosmetic. The FDA treats it as an OTC drug, which means new active ingredients face a more demanding and time-consuming review process.⁸ DSM Nutritional Products (later DSM-Firmenich) first applied to add bemotrizinol to the US sunscreen monograph in 2005, but that application languished for nearly 2 decades. The 2020 CARES Act overhauled the OTC monograph system and created a new, faster administrative order pathway. DSM Nutritional Products LLC, a subsidiary of DSM-Firmenich, filed a new request through that process in September 2024. The FDA issued a proposed order in December 2025 and finalized it on June 9, 2026—about 7 months later.

Bemotrizinol is the first ingredient to clear this new streamlined pathway, bringing the total number of approved active sunscreen ingredients in the US to 17.⁹ The EU, by comparison, has approved more than 30 UV filters. That gap has long meant American consumers had fewer options and, in many cases, weaker UVA protection than people in other countries.¹⁰

5. “How Does It Compare to Other FDA-Approved Sun Filters?”

Most chemical UV filters approved in the US are either UVB-only (octinoxate, octisalate, and homosalate) or UVA-only (avobenzone). Bemotrizinol covers both—it absorbs across the full UVA and UVB spectrum in a single molecule, making it a true broad-spectrum filter on its own.¹¹

Photostability is where the difference becomes clinically meaningful. Avobenzone—currently the only non-mineral filter in the US with meaningful UVA coverage—breaks down in sunlight, sometimes losing a significant portion of its effectiveness within an hour unless paired with a stabilizing agent.¹² Bemotrizinol holds its protective capacity through extended sun exposure and can also help stabilize other filters, including avobenzone, in combination formulations.¹³

Absorption levels also tell an important story. FDA data showed that oxybenzone was detected in the bloodstream at 515 times the FDA’s threshold of concern after just one weekend of use. Bemotrizinol did not meaningfully enter the bloodstream at its approved 6% concentration.¹²

Until now, zinc oxide and titanium dioxide were the only sunscreen ingredients the FDA had designated as GRASE—both of which are mineral filters. Bemotrizinol is the first chemical filter to earn that status in the US.¹ Mineral sunscreens with non-nano zinc oxide remain a well-supported option with a strong safety and environmental record. Bemotrizinol gives patients who prefer chemical formulations—or who find mineral sunscreens difficult to use—a more effective alternative than what has been available.

Bonus: Should Patients With a History of Melanoma Prepare to Switch When Bemotrizinol Products Become Available?

The short answer is: not yet, but it is worth a conversation. The American Academy of Dermatology president called the approval “an important public health step,” noting that skin cancer is the most commonly diagnosed cancer in the US and that roughly 90% of non-melanoma skin cancers are linked to UV radiation exposure.¹⁴

The AIM at Melanoma Foundation advised people with a skin cancer history and the general public to stay the course with their current sunscreen regimen for now. The recommendation: continue using a broad-spectrum SPF 30 or higher product daily, reapply every 2 hours when outdoors, and check with a dermatologist or oncologist before making any changes.¹⁵

Manufacturers may begin adding bemotrizinol to OTC sunscreen products on August 9, 2026, when the FDA’s final order takes effect. DSM-Firmenich holds exclusive marketing rights for the first 18 months. Kenvue, the parent company of Neutrogena and Aveeno, has already confirmed plans to incorporate bemotrizinol into US products.^16,17 Broader availability is expected once exclusivity ends. Dermatologists caring for patients with a melanoma history, a family history of skin cancer, or photosensitive conditions such as melasma may find it helpful to flag bemotrizinol now and revisit the conversation once products reach store shelves.
