@noahcne: If your back acne is uniform, itchy, and worse after sweating, it might not be acne. Malassezia folliculitis looks identical and doesnt respond to acne treatment. For actual truncal acne: BPO wash, left on 2 to 5 minutes before rinsing, plus a retinoid. Contact time is the part people skip.
