Several acne products containing benzene have been recalled due to possible benzene contamination, the Food and Drug Administration (FDA) said this week.

La Roche-Posay and Proactiv are among the brands affected. Popular acne treatments were recalled due to potential contamination with benzene. Research shows that long-term exposure to benzene may increase cancer risk. The U.S. Food and Drug Administration conducted benzene testing on the products after third-party testing raised concerns.

The FDA announced the recall of more acne products due to contamination of benzene, a cancer-causing chemical.While the recalled products contained elevated levels of benzene, the FDA said the risk of developing cancer from using these products is very low.
