Acne does not only appear on the face. The back, chest, shoulders and even the buttocks have plenty of oil glands and can break out too. Body acne is common, treatable, and often responds to a few simple changes.
Why body acne happens
- The same process as facial acne: oil, dead skin and bacteria blocking follicles
- Sweat and friction from tight clothing, backpacks, sports equipment and gym gear (often called acne mechanica)
- Heavy body lotions, oils and hair conditioner running down the back in the shower
- Hormonal changes and genetics
Is it acne or something else?
Small, uniform, itchy bumps on the chest and upper back may be fungal (Malassezia) folliculitis, which does not respond to usual acne treatments and needs antifungal treatment. Pimple-like bumps on the buttocks are often folliculitis from friction rather than true acne. If over-the-counter treatment is not helping, get it checked.
Treatments that work
Benzoyl peroxide wash
A 4% to 10% benzoyl peroxide body wash used in the shower is one of the most effective options. Leave it on the skin for a minute or two before rinsing so it has time to work. Rinse well, as it bleaches towels and clothing.
Salicylic acid
Salicylic acid body washes and sprays help unclog pores and are useful for blackheads and rough texture.
Retinoids
Adapalene can be applied to the chest and back for persistent breakouts, although covering a large area can be impractical.
Prescription treatment
For widespread, inflamed or scarring body acne, a doctor may prescribe oral antibiotics, hormonal treatment or isotretinoin.
Everyday habits that help
- Shower and change clothes soon after exercise.
- Wear loose, breathable fabrics when possible.
- Rinse conditioner off fully, then wash your back last.
- Use non-comedogenic body lotion and sunscreen.
- Wash sports gear, backpack straps and bed sheets regularly.
Body acne tends to take a little longer to clear than facial acne. Give a new routine 8 to 12 weeks, and see a doctor if it is painful or leaving scars.
