Benzoyl Peroxide Storage After the Benzene Reports

Before deciding whether to keep an old benzoyl peroxide wash or cream, put its carton beside the bottle. You need the storage directions, expiry date, lot number and approximate date you began using it.

What the FDA’s 2025 testing found

In its 11 March 2025 announcement, the FDA reported testing 95 acne products containing benzoyl peroxide. More than 90% had undetectable or extremely low benzene levels; six had elevated levels. A seventh product’s manufacturer initiated a recall after its own testing.²

The announced actions were at the retail level, instructing sellers to remove affected products without specifically directing consumers to act on products they already possessed. The agency assessed the cancer risk from the benzene found in those recalled products as very low, even with decades of daily use.²

That assessment describes those findings. It is not a measurement of the bottle you own or a guarantee about every future batch.

Keep an old notice separate from a current lot check

The announcement’s table includes Walgreens Tinted Acne Treatment Cream, lot 49707430, expiring March 2026.² By October 2026, that example is past its expiry date regardless of the recall discussion. FDA advises discarding products past their expiry dates.²

For a product still within date, check the current FDA recall information and the manufacturer’s instructions using the exact name, strength, size and lot. The March 2025 announcement links to FDA’s recall pages. It should not be treated as a complete, continuously updated list of every affected acne product.

If the code is unreadable, photograph the packaging and ask the pharmacist or manufacturer to help identify it.

Follow the storage instructions on your product

The AAD advises following the package’s storage directions, generally room temperature or cooler, with refrigeration given as an example. It also recommends replacing benzoyl peroxide products every 10–12 weeks and discarding products exposed to higher temperatures, giving above 78°F, about 26°C, as an example.¹

These are professional-society precautions, not the consumer instructions from the FDA’s retail recall. Ask the pharmacist how they apply if your prescription contains several active ingredients or its package gives particular storage limits.

Mention a tube left in a hot car or suitcase. Moving it somewhere cooler later does not establish what happened during that exposure, so include the storage history when asking whether to replace it.

Record the date without abandoning the acne plan

Write the opening date on a removable label or in your product record. Add the printed expiry and a reminder to review the bottle’s age. Buying several large backups makes those dates harder to follow.

If you want a different treatment, the AAD recommends discussing alternatives with your dermatologist when benzoyl peroxide is part of the prescribed plan.¹ Bring the product details and explain whether your concern is heat exposure, age, a lot notice or the ingredient itself.

The “Twelve Weeks” section in Skin, Head to Toe uses a Skin Log to record products, start dates and irritation. Add storage and replacement details there, while keeping the bottle’s age separate from the question of whether the treatment is helping your acne.
