Back & Chest Acne: Management Tips for Swimmers

Pre-Swim Preparation

• Gentle cleanse with salicylic acid or benzoyl peroxide wash (leave on 1–2 min).
• Apply non-comedogenic, water-resistant sunscreen (if outdoor).
• Avoid heavy oils/creams that trap chlorine.

Post-Swim Routine (Critical)

1. Rinse immediately with fresh water (poolside shower).
2. Cleanse with mild syndet or medicated wash.
3. Pat dry; apply lightweight, oil-free moisturizer.
4. Change into loose, breathable cotton clothing.

Ongoing Treatment

• Topical retinoid (adapalene 0.1% OTC) nightly—start 2–3×/week, increase tolerance.
• Benzoyl peroxide 2.5–5% leave-on for inflammatory lesions.
• Oral antibiotics (doxycycline, sarecycline) if moderate-severe; limit duration.
• Isotretinoin for refractory/scarring acne (dermatology referral).

Swim-Specific Tips

• Shower before entering pool (reduces chloramine formation).
• Silicone swim cap keeps hair products off back/chest.
• Rash guard (UPF 50+) protects skin from chlorine/sun.
• Hydrate; chlorine is drying.

When to See a Dermatologist

• No improvement after 8–12 weeks consistent OTC regimen.
• Nodulocystic lesions, scarring.
• Psychological distress.
