FDA Approves Bemotrizinol: First New Sunscreen Ingredient in 20+ Years
Why this matters
There’s a new active ingredient for sunscreen now approved by the U.S. Food and Drug Administration (FDA). Called bemotrizinol, it’s the first big update to U.S. sunscreen ingredients in more than 20 years. That’s notable because more ingredient options can mean better protection, better feel on the skin, and more choices for people who avoid sunscreen because it’s greasy or leaves a white cast.
This article is based on an interview with Darrell Rigel, MD, a practicing dermatologist who spoke about what the approval means for doctors and patients.
What is bemotrizinol?
Bemotrizinol is a sunscreen filter that has been used in other countries for years. In simple terms, it’s an ingredient that helps block the sun’s damaging ultraviolet (UV) light. It provides broad-spectrum coverage, which means it helps protect against both UVA and UVB rays. (UVA rays are linked with deeper skin aging and some skin cancer risk, while UVB rays cause sunburn.)
Why experts are paying attention
There are a few reasons bemotrizinol stands out:
- Photostability: It stays effective longer when exposed to sunlight compared with some older filters. That can help a sunscreen keep working during sun exposure.
- Cosmetic feel: It can be mixed into formulas that feel better on the skin, which matters because people are more likely to use sunscreen that feels pleasant.
- Safety profile: The FDA noted minimal systemic absorption (meaning only small amounts get into the bloodstream), which helped in its review.
- Regulatory milestone: Bemotrizinol is the first non-mineral filter besides zinc oxide and titanium dioxide to be recognized by the FDA as generally recognized as safe and effective (GRASE).
How it reached approval in the U.S.
Bemotrizinol has been used and studied in other countries for years. Its U.S. approval followed extensive testing showing broad-spectrum protection and good formulation characteristics. The review was also aided by recent legislation intended to speed up FDA reviews of sunscreen ingredients that are already available internationally (the Sunscreen Standards Act). Congressman John Joyce, MD, a dermatologist serving in Congress, supported that effort.
What this could mean for sunscreen choices
Manufacturers can now begin to add bemotrizinol to new sunscreen products in the U.S. That may lead to sunscreens that offer strong protection and a nicer feel on the skin, which could help people use them more consistently. It also opens a possible path for other sunscreen ingredients used in Europe and Japan to come to the U.S. in the future.
How to think about this as a sunscreen user
Bemotrizinol gives another option, but it doesn’t replace the basics of sun safety. Look for sunscreens labeled broad-spectrum and with an SPF appropriate for your needs, follow application instructions, and reapply regularly, especially after swimming or sweating. If you’re curious about new products that contain bemotrizinol, your dermatologist can help you understand whether a particular formulation might suit your skin type or concerns.
If you like to track visible skin changes (moles, new spots, or changes in existing spots), taking clear photos over time can help you notice changes sooner and be ready to show them to your doctor at a visit.
When to see a doctor
Talk to a dermatologist if you notice a mole or spot that changes size, shape, color, or texture, or if a spot starts to bleed, itch, or hurt. If you’re unsure about which sunscreen is best for your skin or medical history, ask a doctor for personalized advice. For any fast-growing, painful, or infected skin problems, seek prompt medical care.
