FDA Approves Bemotrizinol: A Breakthrough in US Sunscreen Protection
Why this matters: a new sunscreen ingredient approved in the U.S.
There’s important news for sun protection in the United States. The FDA has approved a new over-the-counter sunscreen ingredient called bemotrizinol, the first ingredient added to the U.S. sunscreen rules in more than 20 years. This article explains what bemotrizinol is, how it’s different from other sunscreen ingredients, and what the approval might mean for people who want better sun protection. The information here is based in part on an exclusive video interview with Christopher Bunick, MD, PhD, an associate professor of dermatology at Yale School of Medicine.

Quick summary
Bemotrizinol is a chemical sunscreen ingredient that blocks both UVA and UVB rays. It’s larger than some older chemical filters, so it’s less likely to sink into the skin. The FDA cleared it for use in products for adults and children 6 months and older. It’s also more stable in sunlight and goes on clear, which may make sunscreens easier to wear regularly.
What is bemotrizinol?
Bemotrizinol is a chemical UV absorber. That means it soaks up ultraviolet (UV) light and helps stop that energy from damaging the skin. It provides protection across both the UVA and UVB parts of the spectrum. UVA rays are linked to long-term skin damage and aging, while UVB rays are the main cause of sunburn. Because it covers both types of rays, bemotrizinol helps with goals most people care about, like lowering sunburn risk and reducing sun-related skin damage.
How is it different from other sunscreen chemicals?
There are a few practical differences that matter for everyday use.
- Less likely to be absorbed: Bemotrizinol is a larger molecule than some common chemical filters, such as avobenzone. Larger molecules don’t pass through the outer layer of skin as easily, so there tends to be less absorption into the body. The FDA approved bemotrizinol for use in adults and children 6 months and older.
- More stable in sunlight: Some chemical filters break down when they’re hit by sunlight and need other ingredients to stay effective. Bemotrizinol is more photostable, meaning it holds up better in the sun without losing its protective ability as quickly.
- Cosmetic acceptability: Unlike some mineral sunscreens that can leave a white, chalky look, bemotrizinol is transparent when applied. That can make it easier for people to wear sunscreen regularly. It can also be combined with mineral ingredients like zinc to make broad-spectrum formulas that look and feel nicer on the skin.
What this approval might mean for you
One practical benefit could be better sunscreen options on store shelves. When sunscreens feel and look better, more people may use them consistently. That matters because skin cancer and sun damage remain common concerns in the U.S., and many people — including young people — do not get enough protection from UV rays. The hope expressed by experts is that new ingredients like bemotrizinol will encourage makers to improve sunscreen formulas, fragrances, textures, and wearability.

Practical sun protection tips
Bemotrizinol is an additional tool in the sun-safety toolbox, but it doesn’t replace other good habits. For everyday sun protection, consider these steps:
- Choose a broad-spectrum sunscreen (protects against UVA and UVB) and follow the product’s directions for application.
- Apply sunscreen to all exposed skin and reapply as the product recommends, especially after swimming or sweating.
- Use other protective measures when you can, such as shade, clothing, hats, and sunglasses.
- If you have questions about which products are right for you or a young child, talk with a healthcare provider or dermatologist.
When to see a doctor
See a dermatologist or other healthcare provider if you notice a changing mole, a sore that won’t heal, a spot that bleeds, unusual pain or infection signs, or any fast-growing or suspicious skin change. These symptoms should be evaluated rather than managed with over-the-counter products alone.
Keeping track of visible skin changes
If you’re monitoring moles or other skin spots, consider taking photos over time. Documenting changes can help you spot things earlier and give clear information to a clinician if you need a check-up.
