Benzoyl Peroxide 4% (parent compound generating benzene)

Scout's take

Benzoyl Peroxide is the active acne-fighting ingredient in this product. While effective against acne-causing bacteria, it has been shown to spontaneously decompose into benzene — a Group 1 carcinogen — particularly at warmer temperatures during shipping, storage, and on bathroom shelves. The 4% concentration is the lowest tier of BPO acne products but still generates benzene.
