US Sunscreen Lagging in UVA Protection, Experts Say
As a major heat wave grips the U.S., dermatologists are raising concerns that American sunscreens may not provide adequate protection against harmful ultraviolet radiation, notably UVA rays. These rays are linked to skin cancer and premature aging, and experts say sunscreens in Europe and South Korea often offer better defense.
While U.S.sunscreens generally block UVB rays,which cause sunburn,studies suggest thay are less effective against UVA rays. A 2017 study indicated that only about half of U.S.sunscreens met European UVA protection standards.
The disparity, experts say, stems from regulatory differences. In the U.S., sunscreen is regulated as an over-the-counter drug by the Food and Drug Administration, requiring lengthy approval processes for each active ingredient. This has resulted in a situation where no new UV filters have been approved in over 20 years.
Dermatologist Adewole Adamson told NPR that the issue isn’t the safety of current sunscreens, but their limited spectrum. He said they don’t block UVA rays as effectively as they could, a problem that could be solved if the FDA approved new ingredients.
Other countries, including France, South Korea, the U.K.,and Japan,have approved a wider range of UV-filtering ingredients,allowing for more advanced sunscreen formulations. One such ingredient is bemotrizinol, considered safe and effective, but awaiting FDA approval. Dermatologist Nazanin Saedi told Axios that a decision isn’t expected before 2026.
An FDA spokesperson said that many sunscreens available in the U.S. offer excellent broad-spectrum coverage when used as directed. The agency added that availability of sunscreen ingredients in other countries does not guarantee greater efficacy or safety.
In 2023, U.S. Rep. Alexandria Ocasio-Cortez highlighted the issue, urging Americans to contact their representatives in Congress. Sen. Mike lee agreed, stating that UV light is a bipartisan concern.
A bipartisan bill has been introduced in Congress to modernize sunscreen regulations and allow non-animal testing alternatives.
Despite these concerns about UVA protection,dermatologists emphasize the importance of wearing sunscreen. Dr. Robert Kirsner, a dermatologist at the University of Miami, told CBS that U.S. sunscreens are still safe and effective when used properly. Experts recommend using a broad-spectrum sunscreen wiht an SPF of 30 or higher daily, even on cloudy days. For those seeking the safest options, mineral sunscreens containing zinc oxide and titanium dioxide are recommended.
