The U.S. Food and Drug Administration has approved a new sunscreen ingredient for the first time in more than 20 years. On June 9, the FDA added bemotrizinol, also known as BEMT, to its list of approved active ingredients for over-the-counter sunscreens. The agency considers the ingredient safe and effective for adults and children aged six months and older.
Bemotrizinol is a chemical UV filter that absorbs ultraviolet radiation and converts it into heat, protecting the skin from sun damage. It offers broad-spectrum protection, meaning it shields against both UVA and UVB rays. UVB rays cause sunburn, while UVA rays penetrate deeper and contribute to wrinkles, pigmentation changes, and long-term skin damage. Both types increase the risk of skin cancer.
One key advantage of bemotrizinol is that it provides broad-spectrum protection on its own. Many chemical filters currently available in the United States are stronger against either UVA or UVB rays, requiring manufacturers to combine multiple ingredients for full protection. Bemotrizinol covers both types effectively.
The ingredient is also highly photostable, meaning it remains effective when exposed to sunlight for long periods. Some sunscreen ingredients degrade under UV light over time, leaving the skin vulnerable. According to the FDA’s review, bemotrizinol shows minimal absorption through the skin while still providing effective UV protection.
Consumer advocates, public health experts, and dermatology organizations have supported the addition of bemotrizinol for years. The Environmental Working Group has been among those pushing for access to newer sunscreen filters available in other countries.
Products containing bemotrizinol are not yet on store shelves. Industry experts expect the first sunscreens with the ingredient to appear later this year. This means consumers may soon see formulas that resemble some of the highly praised sunscreens sold in places like France, South Korea, Japan, and Australia.
In the meantime, mineral sunscreens containing zinc oxide and titanium dioxide remain effective options. Many existing broad-spectrum sunscreens also provide strong protection when used correctly. The approval of bemotrizinol does not make current sunscreens ineffective.
Skin cancer remains a major public health concern in the United States. According to the American Academy of Dermatology, about one in five Americans will develop skin cancer in their lifetime. Rates continue to rise, making access to effective sun protection an ongoing priority for health officials and consumers alike.
