FDA Approves New Sunscreen Ingredient Used for Years in Europe and Asia
FDA approves new sunscreen ingredient used – After two decades of stagnation, the U.S. Food and Drug Administration has taken a significant step forward by endorsing a novel sunscreen component—bemotrizinol, abbreviated as BEMT. This decision marks the first update to sunscreen regulations since 2004, according to officials. Experts highlight that the ingredient, which has been safely integrated into formulations across Europe and Asia for over two decades, presents a more secure alternative to many of the chemical-based compounds currently prevalent in American sunscreens.
The Approval and Its Implications
“Bemotrizinol has demonstrated safety in European markets for decades, and this FDA action will boost competition and restore consumer trust in sunscreen products,” stated Robert F. Kennedy, Secretary of the U.S. Department of Health and Human Services, in a statement released alongside the announcement. The approval is particularly welcomed by advocates who argue that the U.S. sunscreen market lacks sufficient options that balance safety and effectiveness. According to the Environmental Working Group’s (EWG) latest annual report, only a minority of products on shelves meet both criteria, leaving many users uncertain about their protection.
Bemotrizinol’s Advantages
Bemotrizinol functions as a chemical filter that excels in blocking ultraviolet A (UVA) radiation, a type of UV light linked to premature aging, immune system suppression, and skin cancer risk. Unlike traditional chemical sunscreens, which rely on reactive compounds to absorb UV rays, BEMT offers a more stable solution. “This ingredient provides robust UVA protection without being readily absorbed into the skin, making it a standout in terms of safety data,” explained Alexa Friedman, a senior scientist at EWG. She emphasized that BEMT’s photostability ensures it remains effective even under intense summer sun, a key advantage over avobenzone, the sole non-mineral UVA-filtering agent available in the U.S. at the time of the approval.
UVA Protection Gap in U.S. Sunscreens
Current U.S. sunscreens are often lauded for their ability to prevent visible sunburns caused by UVB radiation, but they fall short when it comes to shielding against UVA rays. Research from EWG underscores this issue, revealing that, on average, American sunscreens offer just 24% of the UVA protection claimed by their SPF labels. This discrepancy has raised concerns among health organizations like the American Cancer Society, which warns that UVA exposure is a primary driver of long-term skin damage and cancer risk.
The Science Behind Bemotrizinol
EWG’s peer-reviewed analysis of U.S. sunscreen performance highlights the need for improved UVA coverage. While mineral-based products, such as those containing zinc oxide, sit on the skin’s surface and physically block UV radiation, they have historically been criticized for leaving a white residue. Modern mineral sunscreens, however, have refined their formulations to reduce this effect. Chemical sunscreens, on the other hand, are designed to penetrate the skin, creating a reaction that converts UV light into heat. Although this method has been standard for years, recent studies have raised alarms about the absorption of certain chemicals into the bloodstream.
Chemical Sunscreens and Health Concerns
Following the 2019 FDA report, six commonly used chemical ingredients were flagged for potential systemic absorption. Homosalate and oxybenzone, for instance, were found to linger in the bloodstream beyond safe thresholds for over two weeks, even after a single day of application. These findings have prompted calls for further research into the long-term effects of chemical sunscreen components, which are still considered “generally regarded as safe and effective” (GRASE) under existing guidelines. Despite this, no updated regulations have been introduced to address the growing concerns.
Combining Safety and Efficacy
David Andrews, EWG’s chief science officer, hailed the approval of bemotrizinol as a milestone for American consumers. “This is a great day for those who have long advocated for better sunscreen options and closed the UVA protection gap,” he said. “For decades, U.S. sunscreens have relied on outdated technology while global standards advanced.” The inclusion of BEMT allows for the creation of broad-spectrum products that combine the benefits of mineral and chemical filters, offering superior protection without the drawbacks of traditional chemical agents.
Industry Response and Regulatory Context
The Personal Care Products Council (PCPC), representing sunscreen manufacturers, praised the FDA’s decision as a “significant advancement” for both the industry and consumers. However, the group urged further action to streamline the approval process for new ingredients. “While we commend this progress, ongoing efforts are essential to modernize regulations and expand the range of safe, effective options,” said Tesia Williams, a PCPC spokesperson, in an email. The approval of BEMT could set a precedent for future innovations, but experts stress that the journey to fully addressing sunscreen safety is far from over.
Broader Impact on Sun Care
With 550 sunscreen products recommended by EWG in their 2026 report, 497 of these are mineral-based, indicating a growing shift toward safer alternatives. The addition of BEMT to this list could further solidify its role in the market. Unlike older chemical filters, which may require higher concentrations to achieve adequate UVA protection, BEMT is efficient and less likely to cause irritation. Its approval also addresses the “white cast” issue, allowing for a more aesthetically pleasing application without compromising performance.
Consumer Awareness and Future Outlook
“This is a win that has been a long time coming,” Andrews remarked, underscoring the importance of the decision in bridging the gap between U.S. and international sunscreen standards. While the FDA’s approval of BEMT is a positive development, advocates caution that more work is needed to ensure all ingredients are thoroughly evaluated. The ingredient’s robust safety profile, however, provides a strong foundation for future improvements. As the sunscreen market evolves, consumers may soon have access to products that deliver both comprehensive UV protection and peace of mind about their ingredients.
Conclusion: A Step Forward
Although the approval of bemotrizinol is a notable achievement, it remains one piece of a larger puzzle. The ingredient’s integration into U.S. products will likely take time, but its potential to enhance UVA coverage and reduce skin absorption offers a promising direction. As the Environmental Working Group continues to monitor the industry, and the FDA moves to update its guidelines, the hope is that this approval will catalyze a new era of sunscreen innovation and safety in the United States.
