Apply liberally to clean, dry skin on the body as often as needed, or as directed by a dermatologist. For best results, apply after bathing while the skin is still slightly damp to help seal in moisture. Focus on areas prone to roughness and bumps, such as the backs of the arms, legs, and buttocks. Always apply a broad-spectrum sunscreen to exposed areas during the day, as AHAs and BHAs may increase sun sensitivity.
