Apply liberally to clean, dry skin on the body as often as needed, or as directed by a dermatologist. For best results, use 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 upper arms, thighs, and elbows. Always apply a broad-spectrum sunscreen to exposed areas during the day, as AHAs and BHAs can increase sun sensitivity.
