The SAFE Sunscreen Act Just Became Law: Here's the Real Timeline for Better US Sunscreen
A quiet November 2025 law could reshape the US sunscreen aisle, but the better filters won't appear overnight.
The SAFE Sunscreen Standards Act was signed into law on November 13, 2025 as part of the reauthorization of the Over-the-Counter Monograph User Fee Act (OMUFA), requiring the FDA to issue new guidance allowing real-world evidence and alternative testing methods to evaluate sunscreen ingredients.
The Skin Cancer Foundation, a longtime backer of the bill, describes the measure as modernizing how the FDA evaluates sunscreen so testing can rely on real-world evidence rather than only legacy methods.
Questions we get a lot
When was the SAFE Sunscreen Standards Act signed?
It was signed into law on November 13, 2025. It rode in as part of the reauthorization of the Over-the-Counter Monograph User Fee Act (OMUFA). The bill is tracked in Congress as S.2491.
What does 'real-world evidence' mean for sunscreen ingredients?
It means the FDA can consider data from how filters perform and are used in the real world, plus alternative testing methods, rather than relying only on traditional drug-style trials. The law requires the agency to issue guidance enabling this. The aim is a faster, more practical path to approving safe, modern filters.
What is OMUFA and why does it matter here?
OMUFA is the Over-the-Counter Monograph User Fee Act, which funds and structures how the FDA reviews OTC drug ingredients, including sunscreens. The SAFE Sunscreen Standards Act was attached to OMUFA's reauthorization. That vehicle is how the sunscreen reforms became law.
