Benzoyl Peroxide 10%
Low RiskBenzoyl peroxide is an OTC topical acne ingredient. MotherToBaby reports that ACOG includes benzoyl peroxide among ingredients that may be used during pregnancy if needed; only a small amount is expected to be absorbed through the skin. Direct controlled pregnancy data remain limited. MamaSkin retains Low Risk for normal topical use rather than describing the ingredient as proven pregnancy-safe.
