Makeup company L’Oréal S.A. has issued a recall on its popular acne cream Effaclar Duo due to concern that benzene, a known carcinogen, is in the product. Last year, independent Connecticut testing lab Valisure, flagged acne products with benzoyl peroxide, like L’Oréal’s, could contain benzene, reports the New York Post.

The Food and Drug Administration (FDA) recently issued a retail recall for multiple acne-treating cosmetic products made by various brands, including popular skincare brands La Roche-Posay and Proactiv. Recent FDA tests of 95 acne products containing benzoyl peroxide detected possible contamination with benzene, a cancer-causing chemical.
