Shower after sweating; use a gentle, non-comedogenic cleanser
Use a benzoyl peroxide wash (4%–10%) once daily; let sit 1–2 minutes before rinsing
If skin is sensitive, start every other day and moisturize after
Consider salicylic acid (0.5%–2%) body wash in the shower if benzoyl peroxide isn’t tolerated
Avoid scrubbing hard; use a soft washcloth or hands
Keep skin dry; change out of damp clothes and shower promptly after workouts
Wear breathable, loose-fitting clothing; choose moisture-wicking fabrics
Wash bed sheets, towels, and workout clothes regularly; avoid reusing towels
Avoid heavy oils and comedogenic lotions on the back; use non-comedogenic moisturizers
Keep hair products off the back; rinse conditioner well and avoid letting hair touch your back
Clean or replace items that contact your back (backpacks, helmets, straps) regularly
Don’t pick or squeeze lesions; minimize irritation and scarring risk
Try a leave-on acne treatment if needed: adapalene 0.1% gel once nightly (thin layer)
Use topical antibiotics only with a clinician’s guidance if over-the-counter options fail
Consider prescription options if persistent: topical clindamycin, oral antibiotics, or hormonal therapy for eligible cases
For severe or scarring acne, ask a dermatologist about oral isotretinoin
Seek medical advice urgently if acne is very painful, rapidly worsening, or forms large cysts/abscesses
If you use benzoyl peroxide, expect possible bleaching of fabrics; protect towels/clothes with careful rinsing
