Body Acne

Body acne develops when excess oil and dead skin cells clog hair follicles. Bacteria and inflammation can then produce blackheads, whiteheads, pimples, pustules, or deeper nodules and cysts.

Several factors can contribute to body breakouts:

• Hormonal changes
• Genetics and naturally oily skin
• Sweat that remains on the skin
• Friction from tight clothing, backpacks, sports equipment, or bra straps
• Oily lotions, sunscreens, and hair products
• Certain medications
• Delayed showering after exercise

Body acne is not a sign of poor hygiene. In fact, aggressive scrubbing can irritate the skin and make inflammation worse.

Not every breakout is acne. Folliculitis, an inflammation or infection of the hair follicles, can produce clusters of small, acne-like bumps. Heat, friction, shaving, bacteria, and yeast may all contribute to folliculitis.

Because these conditions can look similar but require different treatment, persistent, itchy, painful, or unusually uniform bumps should be evaluated by a dermatologist.

Mild body acne may improve with a consistent, gentle routine.

Shower as soon as practical after exercise or heavy sweating, and change out of damp clothing. Wash affected areas without scrubbing, and choose body-care products labeled “oil-free,” “non-comedogenic,” or “won’t clog pores.”

Over-the-counter washes containing benzoyl peroxide can help reduce inflammatory acne, while salicylic acid may help clear clogged pores. Follow the product directions and introduce one treatment at a time to reduce irritation. Be aware that benzoyl peroxide can bleach towels, sheets, and clothing.

Avoid squeezing or picking at blemishes. This increases inflammation and may lead to infection, discoloration, or scarring. It is also helpful to wash workout clothing regularly and clean equipment that repeatedly touches the skin.

Consider professional treatment by a board-certified dermatologist when body acne:

• Includes deep, painful nodules or cysts
• Is leaving scars or persistent dark marks
• Covers a large area of the back, chest, or shoulders
• Does not improve with consistent over-the-counter care
• Causes significant itching or may be folliculitis
• Affects confidence or leads you to avoid certain clothing or activities

Moderate or severe body acne often requires prescription treatment because the skin of the back and chest can be difficult to treat effectively with over-the-counter products alone. Depending on the type and severity of the acne, treatment may include prescription topical medications, oral medications, extraction procedures, chemical peels, or other in-office therapies.
