Help clarify your complexion with Neutrogena Stubborn Blackheads Daily Acne Facial Serum. Designed for oily, acne-prone skin, this oil-free face serum from a dermatologist-recommended brand visibly clears clogged pores to help eliminate even stubborn breakouts and blackheads. Powered by a dermatologist-grade acid complex, the blackhead remover serum contains 5% glycolic acid, which exfoliates to help remove pore-clogging dirt, oil, and bacteria that can cause acne and blackheads. Other exfoliants--2.5% mandelic acid and 2.5% polyhydroxy acid—are included in our formula with salicylic acid to help prevent and clear up breakouts. A perfect addition to your acne prevention daily skincare routine, this facial serum is fragrance-free, paraben-free, oil-free, phthalate-free, dye-free, and sulfate-free. The lightweight blackhead serum is suitable for all skin tones, and should be layered under moisturizer or makeup. After cleansing, apply a thin layer of the salicylic acid serum to affected areas up to three times per day.
