Elevated levels of benzene were detected in seven acne products distributed to national retailers. Here's what the recall means.

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 U.S. Food and Drug Administration issued a recall notice Tuesday for several lots of six products, including Walgreens Acne Control Cleanser, Proactiv Skin Smoothing Exfoliator, SLMD Benzoyl Peroxide Acne Lotion and La Roche-Posay Effaclar Duo Dual Action Acne Treatment.
