Is benzoyl peroxide still on shelves?
The FDA reports testing 95 benzoyl peroxide products and finding more than 90% with undetectable or extremely low benzene. Only six products showed elevated levels that triggered limited retail-level voluntary recalls, as detailed in the FDA benzene findings update. Harris Beach Murtha's summary of FDA testing notes the agency found very low cancer risk even with daily use for decades.
That finding limits concern but does not remove the need for careful storage. Benzene is a chemical that can form when benzoyl peroxide breaks down over time. The FDA manufacturer alert warns heat, sunlight, and expired product speed that breakdown. Cool storage, expiration checks, and discarding old tubes reduce exposure.
What did the September ruling decide?
On Sept. 15, 2026, Judge Analisa Torres dismissed with prejudice the consolidated benzene case over CeraVe and La Roche-Posay products. Harris Beach Murtha reports the court held state-law warning claims were preempted by FDA over-the-counter labeling rules, as explained in this federal court analysis. George Washington University Media Relations lists four recalled lines that touched buyers of those lots.
They were La Roche-Posay Effaclar Duo, Walgreens Acne Control Cleanser, Proactiv Skin Smoothing Exfoliator, and SLMD Benzoyl Peroxide Acne Lotion. Check any stored tube against its lot number, not just its brand name. The dismissal narrows future warning lawsuits but does not change lot safety or storage needs. Shoppers still need to rely on FDA lot actions and expiration dates.
Can you trust acne reviews?
The Consumer Review Rule is the federal ban on dishonest shopping reviews. The FTC says the rule took effect Oct. 21, 2024 and bans fake reviews, hidden insider posts, paid positive reviews, and suppression. Violations can draw penalties up to $53,088 each.
On Dec. 22, 2025, FTC staff sent warning letters to 10 companies over possible rule violations, as described in the FTC warning announcement. The FTC flagged fake reviews and paying for only 5-star reviews as examples. For acne shoppers, glossy ratings can hide irritation, weak dosing, or poor storage. Treat detailed reviews with photos, timelines, and skin-type notes as more useful than star counts.
How should you shop and store treatments now?
The American Academy of Dermatology still strongly recommends benzoyl peroxide, topical retinoids, and fixed-dose combinations. It advises avoiding antibiotic use alone, as listed in these updated acne guidelines.
Use that standard plus safe handling to judge drugstore options. These habits help: If you own Effaclar Duo, Walgreens Acne Control Cleanser, Proactiv Exfoliator, or SLMD Lotion from the recalled lots, stop using that lot. Replace it with a fresh, in-date product stored cool from the start.
- Keep tubes in a cool drawer away from sun and heat.
- Check the expiration date before each new tube.
- Throw away expired product rather than finishing it.
- Compare reviews against ingredients and dosing, not stars alone.
