Valisure tested 99 acne products containing benzoyl peroxide and found that when exposed to higher temperatures, they can develop high levels of benzene, a potentially cancer-causing chemical. This was not seen in products containing salicylic acid or adapalene. Valisure has submitted a citizen petition to the FDA to recall BPO-containing products and suspend sales, as well as to investigate the manufacturing processes. The discovery of benzene formation in benzoyl peroxide products differs from previous findings in other consumer products. The organization urges urgent action to address the issue in both prescription and over-the-counter products.
