Some selected ingredient names match, but amounts and the rest of each formula may differ. Open an ingredient explanation to see its intended use and the kind of evidence behind it.

Check the whole product for precautions.

An ingredient name cannot predict your skin’s reaction. Cosmetics can cause irritation or allergic reactions. Check the complete label and follow the product directions.
