When it comes to bacne, over-the-counter treatment options include benzoyl peroxide side washes, salicylic acid washes/wipes, and adapalene 0.1% gel (Differin and La Roche-Posay Effaclar). When it comes to acne scars on the back, I recommend using more exfoliating products, like washes or wipes/peels with salicylic acid and glycolic acid. The @skinfixinc acne+ cleanser has a little bit of azelaic acid and niacinamide that can further help with acne marks.
