FDA Approves First New Sunscreen Ingredient in 20 Years

For the first time in 20 years, the U.S. Food and Drug Administration has approved a new sunscreen ingredient that experts say could improve protection against harmful ultraviolet rays.

The ingredient, known as Bemotrizinol or BEMT, has been widely used in Europe since 2000 and is expected to become available in the United States later this summer.

According to dermatologists, one of the major benefits of bemotrizinol is its ability to provide stronger protection against UVA rays, which penetrate deeper into the skin and contribute to premature aging and skin cancer. While many existing U.S. sunscreens effectively block UVB rays that cause sunburns, some experts say they offer less comprehensive UVA protection.

Debra Sarnoff, president of the Skin Cancer Foundation, says the new ingredient has a long track record of safe use overseas and is not easily absorbed into the skin.

Another advantage is cosmetic appeal. Unlike some traditional mineral sunscreens that can leave a noticeable white cast, bemotrizinol-based formulas are expected to blend more easily into different skin tones. Dermatologists say that could encourage more people to wear sunscreen consistently.

Experts note that the new product should still be used the same way as existing sunscreens. Users should apply it 15 to 20 minutes before sun exposure and reapply every two hours, as well as after swimming or sweating.

Skin cancer remains the most common form of cancer in the United States, and dermatologists believe the addition of another effective sunscreen option could help improve sun safety and potentially save lives by increasing regular sunscreen use.
