Bemotrizinol: The FDA’s New Sunscreen Ingredient Explained

In my more than 25 years as a licensed esthetician, sunscreen has always been central to my skincare philosophy. While I believe regular exposure to natural daylight has many important benefits, I’m equally passionate about protecting delicate facial skin from UV damage, a leading cause of premature aging.

For years, my go-to products have been zinc-based mineral sunscreens, and there’s a very personal reason. I still remember having an absolutely horrifying reaction to a spray-on sunscreen that left my skin red and covered in welts. That experience made me rethink what I was putting on my skin and what I recommend to my clients, and I’ve avoided chemical sunscreens ever since.

And after decades of working in aesthetics, there’s finally something new to talk about.

On October 15, Health and Human Services Secretary Robert F. Kennedy Jr. took to X to highlight bemotrizinol, the first new sunscreen active ingredient added to the FDA’s list of permitted over-the-counter sunscreen ingredients since the late 1990s. The FDA officially authorized its use on June 9, 2026, and the first U.S. products containing it began reaching consumers in August.

What makes this particularly interesting is that bemotrizinol isn’t actually new. It has been used in sunscreens across Europe, Australia, and parts of Asia for more than 20 years.

What Is Bemotrizinol, and Why Is It Different?

Bemotrizinol is a chemical sunscreen filter that provides broad-spectrum protection against both UVA and UVB rays.

If you’re unfamiliar with the difference, UVA rays penetrate more deeply into the skin and contribute to premature aging, including fine lines, wrinkles, and discoloration. UVB rays are primarily responsible for sunburn. Both contribute to skin cancer risk.

What makes bemotrizinol particularly promising is its ability to protect against both types of ultraviolet radiation while remaining highly stable when exposed to sunlight.

According to the FDA, studies found that bemotrizinol has very low absorption through the skin and demonstrated a favorable safety profile, with no instances of irritation, phototoxicity, or photoallergenicity reported in the dermal studies reviewed.

The agency has authorized bemotrizinol in concentrations up to 6% for use in qualifying sunscreen products intended for adults and children 6 months and older.

For anyone who has struggled to find a sunscreen that feels comfortable enough to wear every day, having another formulation option is welcome news.

Does This Mean Chemical Sunscreens Are Better Than Mineral Sunscreens?

Not necessarily, and I certainly won’t be throwing away my mineral sunscreens.

Zinc oxide and titanium dioxide have been used for years to provide UV protection. I particularly appreciate zinc-based formulas because they work well for my skin, and I know what to expect.

One drawback, however, is that some mineral sunscreens can leave a noticeable white cast, especially on darker skin tones. Depending on the formulation, they can also feel heavier than some chemical alternatives.

Bemotrizinol gives manufacturers another way to create broad-spectrum formulas that may feel lighter and blend more easily into the skin. It can also be combined with mineral filters like zinc oxide, and there’s already a product on the U.S. market doing exactly that.

Australian skincare brand Ultra Violette introduced its Unblock Screen SPF 50 in August 2026. The fragrance-free formula contains 10% zinc oxide, 3% bemotrizinol, and 6% octocrylene, another chemical UV filter. It’s marketed as a lightweight, soft-matte sunscreen for oily, breakout-prone skin.

But there’s something important to understand: Just because an ingredient has a favorable safety profile doesn’t mean every product containing it will agree with everyone’s skin.

Sunscreens contain more than active UV filters. Fragrances, preservatives, and other ingredients can also contribute to irritation or allergic reactions.

Looking back, I’ve often wondered whether my reaction years ago was caused by the UV filter or something else in that spray. That’s exactly why I read the full ingredient list, not just the actives, before trying anything new.

Why Sun Protection Matters for Aging Skin

Throughout my career, I’ve worked with clients concerned about fine lines, uneven pigmentation, sunspots, and changes in skin texture.

While plenty of treatments and skincare ingredients address these concerns, protecting the skin from excessive UV exposure remains one of the most important steps in preventing further damage.

UVA exposure matters because it contributes to the breakdown of collagen and elastin, the proteins that help skin maintain firmness and elasticity.

That’s why I have always encouraged my clients to think of sunscreen as part of their daily skincare routine, not something reserved for pool days.

Of course, sunscreen is only one part of sun protection. Hats, sunglasses, shade, and limiting exposure during peak UV hours also matter.

And regardless of which sunscreen you choose, proper application and reapplication matter just as much as the formula itself.

Will I Be Trying Bemotrizinol Sunscreen?

I’m certainly interested, although I’ll be paying close attention to the complete ingredient list before putting anything new on my body.

Given my history, a formula that pairs bemotrizinol with zinc oxide is particularly appealing. Ultra Violette’s new sunscreen has caught my attention. However, the inclusion of octocrylene, a chemical filter linked to allergic and photoallergic skin reactions in some people, makes me unlikely to try it.

After years of working with skin, I’ve learned that just because a product is new doesn’t necessarily mean it’s the best for everyone. What matters is finding something effective that your skin tolerates well enough to use consistently.

For now, my mineral sunscreens aren’t going anywhere.

But I think it’s encouraging that American consumers finally have access to a sunscreen ingredient used internationally for decades.

And if bemotrizinol helps manufacturers develop more comfortable, effective formulas that people actually enjoy wearing, that’s a positive development for skincare.

After all, the best sunscreen is one that provides adequate protection and that you’ll consistently use.
