Roche Posay, Proactiv, and Walgreens over Benzene, a known carcinogen. Here’s a list of affected products and what to do.

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.

The safety of skin care has come under scrutiny as elevated levels of the carcinogen benzene have been found in acne creams.
