FDA Approves BEMT UV Filter as La Roche-Posay Launches New Sunscreen

The United States food and safety regulator approved the UV filter bemotrizinol, known as BEMT, in June, opening the domestic market to products using an active ingredient utilized in Asia, Europe, and Australia since the late 1990s, menshealth.com reported.

Key Clinical Takeaways:
• The Food and Drug Administration approved bemotrizinol in June, marking the first newly approved sunscreen filter in the United States since 1999.
• La Roche-Posay released Anthelios UVDefense Sunscreen SPF 50 with BEMT early this week as one of the first products featuring the ingredient in the domestic market.
• Testing over a month showed the chemical filter absorbs both UVA and UVB rays without leaving a white cast, though it lacks water or sweat resistance.

The Approval of Bemotrizinol in the United States

The decision by the Food and Drug Administration to approve BEMT in June brings the domestic market in line with regulatory approvals long established in other developed regions. Brands are releasing products featuring the chemical filter following the mid-year regulatory action. La Roche-Posay introduced its Anthelios UVDefense Sunscreen SPF 50 with BEMT early this week as one of the initial offerings utilizing the newly permitted active ingredient.

BEMT Absorbs UVA and UVB Rays for Skin Protection

BEMT functions as a chemical UV filter by absorbing ultraviolet radiation rather than physically blocking it like mineral ingredients. BEMT absorbs both UVA rays, which contribute to early aging and skin cancer, and UVB rays, which cause sunburns and surface damage. The formula achieves faster absorption and a lighter application than other chemical actives while remaining photostable under direct sunlight.

The La Roche-Posay formulation combines BEMT with avobenzone, homosalate, octisalate, and octocrylene. Glycerin and soybean oil provide additional hydration, and the product remains fragrance-free for sensitive skin.

Sunscreen Absorbs Quickly but Lacks Water Resistance

Testing the sunscreen over a month revealed a texture resembling a thick mineral sunscreen combined with a daily moisturizer. The formula absorbs fully within 15 seconds without leaving a white cast or chemical odor. The primary limitation identified during testing is the lack of water and sweat resistance, requiring users to select separate formulations for exercise.
