Beauty experts know that daily use of SPF will help your skin's longevity and will protect you from skin cancer; however, the available options in the United States, compared to other nations in Europe and Asia, still contain harsh chemicals that are not as safe as thought. For the first time in 20 years, the US Food and Drug Administration (FDA) has approved a new sunscreen ingredient, marking a major milestone for sun protection in the United States.
The newly authorized ingredient, bemotrizinol (BEMT), has been used in Europe for decades and is widely considered one of the most effective and well-studied ultraviolet (UV) filters available today.

US Health and Human Services Secretary Robert F. Kennedy Jr. called the decision a positive step forward for consumers. “Bemotrizinol has been used safely in Europe for decades, and the FDA’s action will increase competition and consumer confidence in sunscreen products,” Kennedy said in a statement announcing the approval.
Why Bemotrizinol and Why Now
While most sunscreens sold in the United States effectively block ultraviolet B (UVB) rays that cause sunburn, many experts argue they do not provide sufficient protection against ultraviolet A (UVA) rays.

Despite broad-spectrum labeling requirements, critics say many American sunscreens fall short when it comes to meaningful UVA defense.
According to research shared by CNN and cited by the Environmental Working Group (EWG), US sunscreens provide only a fraction of the UVA protection consumers may assume based on SPF labels.
Bemotrizinol could help change that. The ingredient is known for delivering strong UVA coverage while remaining highly photostable, meaning it does not rapidly break down when exposed to sunlight. This stability allows sunscreen formulas to maintain their effectiveness for longer periods during sun exposure.

A Potential Alternative to Older Chemical Filters
The approval arrives amid ongoing concerns about certain chemical sunscreen ingredients currently used in the United States. In 2019, FDA research found that several commonly used sunscreen chemicals could enter the bloodstream at levels that exceeded agency safety thresholds after just one day of use. Some ingredients remained detectable in the body for weeks after application.
As a result, regulators have sought additional safety data for several chemical UV filters before classifying them as "generally regarded as safe and effective."

Another advantage is its compatibility with mineral sunscreen ingredients such as zinc oxide. Experts say combining bemotrizinol with zinc oxide can provide broad-spectrum protection while reducing the white cast that has traditionally discouraged some consumers from using mineral sunscreens.
Currently, many health advocates recommend mineral-based sunscreens because ingredients such as zinc oxide and titanium dioxide sit on the skin's surface rather than being absorbed into the body. Advances in formulation have also made modern mineral sunscreens less likely to leave visible residue on the skin.

Health experts also have long argued that Americans have had fewer sunscreen options than consumers in Europe and parts of Asia, where newer UV filters have been available for years.

For consumers concerned about skin cancer prevention, photoaging, and daily sun protection, the addition of bemotrizinol represents one of the most significant sunscreen developments in decades.
