This medication is used to treat acne on the skin. Adapalene (a retinoid) and benzoyl peroxide are combined in this medication (an antibiotic and skin-peeling agent). This product may reduce the number and severity of acne pimples while also promoting rapid healing of those that do appear. Adapalene works by inhibiting cell growth and decreasing swelling and inflammation. Benzoyl peroxide works by reducing the amount of acne-causing bacteria in the skin and causing it to dry and peel away. Before using this medication, wash your hands. Gently clean and pat dry the affected skin with a mild or soapless cleanser. Use a thin layer of this medication once a day, or as directed by your doctor.
