Do you trust that U.S. sunscreen regulations provide you with the best available protection?
Consumer Reports evaluated sunscreens from three Korean brands, finding that all tested formulas provided stronger UVB protection than their U.S. versions. This comparison highlights ongoing differences in how various regions regulate and approve protective UV filters.
Why it matters
Differences in protection often stem from the regulatory classification of sunscreens as drugs in the U.S., which requires a long, complex approval process for new ingredients that is not mirrored in South Korea.
In a head-to-head evaluation of six products from three brands, Korean formulations consistently demonstrated superior UVB protection compared to their U.S.-sold versions. This testing follows a 25-year period in which no new UV-filter ingredients were approved for use in the United States.
The players
FDA
The United States Food and Drug Administration regulates sunscreen products as drugs, overseeing the approval process for all active UV-blocking ingredients.
Consumer Reports
An independent non-profit organization that performs comparative product testing and consumer safety research across various industries including personal care.
The details
The FDA treats sunscreens as drugs, requiring a rigorous and lengthy approval process for new UV filters, whereas South Korean regulators classify them as cosmetics. This regulatory gap has limited the availability of newer, often more effective filters in the American market. As of August 9, regulators have approved the use of bemotrizinol in U.S. products, a development that may eventually bridge the current protection gap between domestic and international formulas.
Timeline
August 9: Manufacturers gained the ability to begin incorporating the UV filter bemotrizinol into U.S. sunscreen products.
Health Landscape
The current U.S. standard of care for sun protection is largely defined by the FDA drug-approval process, which has remained largely stagnant for 25 years. Recent authorization for new filters marks a potential departure from this historical constraint on ingredient innovation.
Regardless of the brand or formula, dermatologists continue to recommend using a sunscreen with at least SPF 30. Ensure you are applying enough product and reconfirming coverage every 2 hours, as even high-performing formulas require consistent usage to remain effective.
The takeaway
While international formulations may offer increased UVB protection, the most effective sunscreen is the one you apply consistently and in sufficient amounts. Talk to your dermatologist about which SPF levels and broad-spectrum ingredients are best suited for your specific skin type and lifestyle needs.
