Breakthrough Sunscreen: Broad Protection Without Streaks
15 Oct
Summary
- Bemotrizinol offers broad UVA/UVB protection without white streaks.
- The new ingredient has minimal skin absorption, unlike older chemicals.
- BEMT is more stable and less prone to breaking down in sunlight.
For the first time in over 25 years, consumers in the United States have a new sunscreen ingredient available: bemotrizinol, or BEMT.
The U.S. Food and Drug Administration approved BEMT in June, and sunscreens containing it are now appearing on store shelves. This chemical has been a popular choice in Europe and other regions for decades.
BEMT provides broad-spectrum protection against both UVA and UVB rays, a significant advantage as it achieves this without the common cosmetic issues like white streaking. This dual protection previously required mixing multiple ingredients.
Dermatologists highlight that BEMT has extensive safety data, demonstrating minimal absorption into the skin. This contrasts with some older sunscreen chemicals that raised concerns about skin penetration and potential buildup in the body.
The FDA's review indicated BEMT did not cause irritation or allergic reactions in studies. It has been designated as generally recognized as safe and effective, similar to mineral-based ingredients like zinc oxide and titanium dioxide.
Furthermore, BEMT is noted for its stability, unlike some older UVA filters that break down quickly in sunlight. However, more research is needed on its environmental impact on coral reefs, though initial findings suggest limited toxicity compared to some banned ingredients.
