High levels of the cancer-causing chemical benzene were found in various benzoyl peroxide (BPO) acne products from major brands, including Proactiv, Clinique, Clearasil, and more.

Valisure LLC, an independent testing laboratory, filed a petition with the US Food and Drug Administration (FDA) on Tuesday, requesting a recall of treatments affected by elevated levels of the carcinogen in order to allow regulators to investigate.
