U.S. health officials are asking retailers to pull a small number of acne creams from their store shelves after government testing found they contain slightly elevated levels of a chemical associated with cancer.

A harmful chemical found in some acne treatments, has raised concerns among skincare users and authorities alike.

Parent company La Roche-Posay has pulled the Effaclar Duo Acne Spot Treatment from L'Oreal's lineup, due to a cancer-causing carcinogen contamination.
