Even with daily use of these products for decades, the risk of a person developing cancer because of exposure to benzene found in these products is very low.”

The agency announced that after concerns were raised about levels of benzene in products containing benzoyl peroxide, they tested 95 acne products with the ingredient. While most had “undetectable or extremely low levels of benzene,” six products showed “elevated levels” of benzene.

Now more products have been recalled due to the same reason. Health reported Wednesday how L’Oréal took their popular La Roche-Posay Effaclar Duo acne treatment due to a potential benzene contamination. An independent lab, Vailsure, alerted the U.S. Food and Drug Administration (FDA) to this issue after testing revealed this contamination.
