FDA Approves New Sunscreen Ingredient Bemotrizinol for Enhanced UV Protection
The Food and Drug Administration has approved bemotrizinol for use in U.S. sunscreens, marking the first time in nearly three decades the agency has cleared a new chemical UV filter. According to Dr. Heather Rogers, a dermatologist in Seattle, the ingredient offers broad-spectrum protection against UVA and UVB rays, addressing a long-standing gap in American sun protection options.
Did You Know?
The approval process for bemotrizinol was extensive, with the European company DSM-Firmenich spending at least $18 million over more than two decades to meet U.S. safety and efficacy standards for over-the-counter drugs.
Why the new filter matters
Current U.S. chemical sunscreens often rely on avobenzone to block UVA rays, which cause aging and skin damage. According to cosmetic chemist Kelly Dobos, avobenzone is not photostable and can break down rapidly in sunlight. This degradation can lead to skin irritation, a concern highlighted by Alexa Friedman, a senior scientist with the Environmental Working Group. Bemotrizinol is photostable, meaning it maintains its protective qualities longer than current alternatives.
Improving sunscreen aesthetics
Beyond its chemical stability, bemotrizinol is transparent on the skin. Dr. Rogers notes that existing mineral-based options, such as zinc oxide, often leave a white, ashy residue that can be difficult for people of color to use regularly. Because bemotrizinol is effective on its own, manufacturers may soon produce less greasy, more aesthetically pleasing formulas that do not require as many stabilizing additives.
Expert Insight:
The shift toward bemotrizinol represents a significant move toward public health by prioritizing user experience. When sunscreens are non-irritating and transparent, consumers are more likely to apply them in the correct amounts, potentially increasing overall compliance with cancer-prevention habits.
What could happen next
Consumers may begin to see products containing the new filter on store shelves as early as September. DSM-Firmenich currently holds exclusive rights to market the ingredient in the U.S. for an 18-month period under the brand name Parsol Shield. As these products enter the market, the industry may see a shift in consumer trust, as bemotrizinol possesses a well-documented safety profile that includes data on skin absorption and potential irritation.
Frequently Asked Questions
Is bemotrizinol a new invention?
No, it has been widely used in sunscreens across Europe and Asia for decades.
Does this mean I don’t need to reapply sunscreen every two hours?
No, experts still recommend reapplying sunscreen every two hours, even with the enhanced stability of the new filter.
Is this ingredient absorbed into the bloodstream?
Clinical testing suggests that because bemotrizinol’s molecules are larger than those of other chemical filters, it is not readily absorbed by the skin into the bloodstream.
