Benzoyl peroxide and benzene: what the follow-up actually showed

Benzoyl peroxide (BPO) has been an acne staple for decades, so the "it forms benzene" headlines worried a lot of people. Here is what the US FDA testing and the American Academy of Dermatology (AAD) guidance say.

What the FDA found

• In March 2025 it tested 95 acne products containing BPO.

• More than 90% had undetectable or extremely low benzene; six products showed elevated levels.

• Manufacturers ran voluntary recalls at retail level, pulling items from store shelves and online listings.

Storage habits the AAD suggests

• Keep products at room temperature or cooler, as the pack says
• Replace them roughly every 10–12 weeks
• Throw out anything that sat somewhere hot, like a car in summer

The FDA described the cancer risk from benzene in these products as very low. If you are still uneasy, a dermatologist can talk you through alternatives.

Where did your BPO live this summer: bathroom shelf or a cool drawer?
