Cancer-causing chemical benzene found in some acne treatments, US lab reports

High levels of cancer-causing chemical benzene were detected in some acne treatments of brands including Estee Lauder’s Clinique and Target’s Up & Up, independent US laboratory Valisure said on Wednesday.

The New Haven, Connecticut-based lab has also filed a petition with the US Food and Drug Administration, calling on the regula-tor to recall the products, conduct an investigation and revise industry guidance.

Benzene, which has already been found in certain sunscreens and dry shampoo, could form at “unacceptably high levels” in both prescription and over-the-counter benzoyl peroxide acne treatment products, said Valisure.

Estee Lauder shares dropped 3 percent following the report.

High levels of benzene were not only found in the acne products tested, but also in the air around incubated products, indicating that the carcinogen could leak out of some of the packages, posing a potential inhalation risk, Valisure said.
