Here's What You Need to Know About Bemotrizinol

This article is for informational purposes only and is not medical advice. Always consult your provider before making changes to your skincare routine.

What is bemotrizinol?

Bemotrizinol, pronounced beh-mo-TRIZ-in-ol, is a broad-spectrum UV filter, which means it protects against both UVA and UVB rays in a single molecule. It's been used safely in sunscreens across Europe and Asia since 1999, meaning there's a 25-year real-world safety record before it ever reaches shelves in the US as early as August 2026.

How is this different from current sunscreen made in the US? 

Most sunscreens in the U.S. are formulated primarily to protect against UVB rays—the rays responsible for sunburn. That's also what the SPF number on the label measures. UVB protection matters, and the sunscreens many people use every day do that job well.

But there's a second type of UV radiation that doesn't cause sunburn and isn't reflected in the SPF number: UVA.

UVA rays penetrate deeper into the skin. Where UVB sits closer to the surface and causes the burn you feel, UVA reaches the deeper layers where collagen lives. Over time, UVA exposure contributes to:

• Fine Lines 
• Wrinkles 
• Loss of Firmness 
• Uneven Tone
• Hyperpigmentation

UVA rays are present year-round, all day, and even come through glass. That means even if you’re mostly indoors, UVA exposure is still possible.

Bemotrizinol is specifically designed to provide strong, stable UVA and UVB protection. It absorbs UV energy and releases it as harmless heat. Plus, based on data reviewed by the FDA, it is considered highly photostable, meaning it holds up throughout the day rather than breaking down with sun exposure. That all-day consistency is one of its most meaningful qualities for long-term skin health.

Why Bemotrizinol Matters

You’ve invested in your skin so it’s worth protecting. Daily sun protection, especially strong UVA coverage, is one of the ways to preserve your results long term. Bemotrizinol gives your skincare routine a boost in protecting against collagen breakdown, wrinkles, and hyperpigmentation, and is especially important for those who have: 

• A history of laser, IPL, or resurfacing procedures
• Melasma or hyperpigmentation concerns
• Post-surgical or post-treatment skin
• A strong anti-aging focus in their skincare routine

Skin that's actively healing from a surgical procedure or medspa treatment is particularly vulnerable to UV-triggered hyperpigmentation. UV exposure during recovery can darken healing tissue, like scars, which is why strong, stable UVA and UVB coverage matters in the weeks and months after treatment.

In the U.S., one manufacturer has first-to-market rights, with broader availability across more brands expected by 2028.

We'll be paying close attention to which formulas come to market, and of course, we’ll keep you updated as trusted formulas become available.

Is bemotrizinol safe?

Bemotrizinol has been used in sunscreens internationally for over 25 years without serious safety signals. In addition to its long international track record, the FDA reviewed clinical trial data, a two-year carcinogenicity study, and lab studies on hormonal activity. 

As of June, the FDA officially classified bemotrizinol as GRASE (Generally Recognized as Safe and Effective), and approved it for use in adults and children as young as six months.

As with any skincare addition, if you have specific health considerations, such as pregnancy, breastfeeding, skin sensitivities, or existing conditions, always check with your healthcare provider before making a change.

When can you get it?

The FDA's final order takes effect August 9th of this year, meaning products can be sold starting that date. Initial availability will be limited. We'll keep you posted as we continue to vet and research new formulas. 

In the meantime, the sunscreens you know and love still offer effective broad-spectrum protection, and consistent daily use of any quality SPF is always the right move. 

Is this replacing my current sunscreen? 

Bemotrizinol is a new option, not a reason to change what's already working. If your current SPF is part of a consistent routine and your skin is responding well, that matters. Stick with it. Every skin is different, and what works well for one person may not be the right fit for another. If you're curious about whether a switch might make sense for you, that's a conversation worth having with your medspa or healthcare provider. They can look at your full picture and help you decide.

Can I use it if I'm pregnant or breastfeeding? 

The FDA approved bemotrizinol broadly. That said, pregnancy and breastfeeding require extra care with any new product. Always check with your healthcare provider before making a switch.

Does SPF still matter if the sunscreen has bemotrizinol? 

Yes! SPF measures UVB protection and remains the standard on labels. Bemotrizinol works within that framework, contributing to SPF while adding strong UVA coverage. You want both working for you, and your provider can help you understand what to look for on the label.

What about mineral sunscreens? Are they still a good option? 

Yes, zinc oxide and titanium dioxide remain reliable, well-tolerated choices, especially for sensitive or post-procedure skin. Bemotrizinol is simply another option, not a replacement for what already works for you. A sunscreen you use consistently every day is doing its job. Your medspa provider can help you find the right fit for your skin.

Why did it take 25 years for the U.S. to approve this? 

It comes down to how sunscreens are regulated here. In the U.S., sunscreens are classified as over-the-counter drugs, which means they go through a more rigorous FDA review process than the cosmetic classification used in Europe. That higher bar takes time. But it's also why the approval, now that it's here, carries real weight.

Sun protection is one of the most powerful tools in any skincare routine. It preserves skin tone, reduces hyperpigmentation risk, and protects the results you've put time and money into.
