The Bottom Line

Body acne — breakouts on the back, chest, and shoulders — is extremely common, affecting up to half of people with acne-prone skin. It's caused by the same factors as facial acne (clogged pores, oil, and bacteria) but can be harder to treat because the skin on your body is thicker. The good news: effective treatments range from over-the-counter washes to prescription medications, and simple lifestyle changes like wearing breathable clothing can make a real difference.

What Is Body Acne?

Body acne is acne that appears on areas other than your face — most commonly the back ("bacne"), chest, and shoulders. It develops when pores become clogged with dead skin cells and oil, allowing bacteria to multiply and cause inflammation. While it follows the same basic process as facial acne, body acne has some unique challenges: the skin on your trunk is thicker, has more oil glands, and is constantly in contact with clothing and friction.

Body acne affects approximately 25-50% of people who are prone to breakouts and is more common in males. It often persists longer than facial acne and can continue into adulthood even after facial breakouts have cleared.

What Does Body Acne Look Like?

Body acne can range from mild to severe and may include:

  • Blackheads and whiteheads: Small, non-inflamed clogged pores
  • Red bumps (papules): Inflamed, tender spots
  • Pus-filled pimples (pustules): Red bumps with a white or yellow center
  • Deep, painful lumps (nodules or cysts): Larger, deeper breakouts that can cause scarring

The most commonly affected areas are the upper back and shoulders, but breakouts can also appear on the lower back, chest, buttocks, and upper arms.

What Causes Body Acne?

Body acne is caused by four main factors working together:

Excess oil production: The oil glands on your back and chest are larger and more active than those on your face, producing more sebum that can clog pores.

Clogged pores: Dead skin cells build up inside hair follicles. On the body, follicles are larger with a curved shape that traps debris more easily.

Bacteria: Cutibacterium acnes (the acne-causing bacterium) thrives in the oily environment of trunk skin.

Inflammation: Your immune system reacts to clogged, bacteria-filled pores, causing redness, swelling, and pain.

Physical factors that make body acne worse:

  • Friction from tight clothing, backpacks, or sports equipment
  • Sweating — especially when sweat stays trapped against skin
  • Heat and humidity
  • Tight or non-breathable synthetic fabrics
  • Not showering promptly after exercise

Treatment Options

Treatment depends on how severe your body acne is:

For mild body acne (mostly blackheads and small bumps):

  • Benzoyl peroxide wash (5-10%): Kills acne bacteria and helps unclog pores. Use as a body wash in the shower — apply, leave on for 1-2 minutes, then rinse. Note: it can bleach towels and clothing.
  • Salicylic acid (2%): Helps dissolve the buildup inside pores. Available in body washes, sprays, and pads.
  • Adapalene gel (0.1%): A retinoid now available over the counter that helps prevent clogged pores. Apply a thin layer to affected areas at night.

For moderate body acne (widespread red bumps and pimples):

  • Prescription-strength retinoids: Your dermatologist may prescribe stronger retinoids to normalize skin cell turnover.
  • Azelaic acid (15-20%): Fights both bacteria and inflammation.
  • Combination products: Benzoyl peroxide paired with a topical antibiotic (like clindamycin) for a stronger approach.

For severe body acne (deep cysts, nodules, or risk of scarring):

  • Oral antibiotics: Doxycycline or minocycline taken for 6-12 weeks to reduce bacteria and inflammation from the inside out.
  • Hormonal therapy: For women, oral contraceptives or spironolactone can reduce oil production.
  • Isotretinoin (Accutane): The most powerful acne treatment and the only one that can produce long-term remission. Reserved for severe cases due to significant side effects and monitoring requirements.

Professional treatments:

  • Chemical peels with salicylic acid for the back and chest
  • Blue light therapy to kill acne bacteria
  • Photodynamic therapy (PDT) for severe, resistant cases

Preventing Body Acne

These practical steps can help reduce breakouts:

  • Shower promptly after sweating — don't let sweat dry on your skin
  • Wear loose, breathable clothing — choose moisture-wicking fabrics during exercise
  • Reduce friction — adjust backpack straps, sports pads, and bra straps that rub
  • Use a medicated body wash — benzoyl peroxide or salicylic acid formulas help prevent new breakouts
  • Don't pick or squeeze — this worsens inflammation and increases scarring risk
  • Change out of sweaty clothes quickly — sitting in damp clothing traps bacteria and moisture against your skin

Scarring from Body Acne

Severe or long-lasting body acne can leave permanent scars, especially on the back where thicker skin heals less smoothly. Some people are prone to raised (hypertrophic or keloid) scars. Early, effective treatment is the best way to prevent scarring. If scarring has already occurred, treatments like microneedling, fractional laser therapy, and subcision can improve appearance, though complete removal is rarely possible.

When to See a Dermatologist

  • Over-the-counter treatments haven't helped after 6-8 weeks of consistent use
  • You have deep, painful cysts or nodules
  • Your body acne is leaving scars
  • Breakouts are affecting your self-confidence or daily life
  • You have dark marks (post-inflammatory hyperpigmentation) that aren't fading

A board-certified dermatologist can create a personalized treatment plan that may include prescription medications not available over the counter.

Frequently Asked Questions

Why is body acne harder to treat than facial acne?

The skin on your back and chest is thicker than facial skin, which makes it harder for topical treatments to penetrate. Body skin also has more and larger oil glands, and friction from clothing creates additional irritation. This is why body acne sometimes requires oral medications when topical products alone aren't enough.

Can body acne be permanently cured?

Body acne typically improves significantly with the right treatment, but it may return if you stop treatment — similar to managing any chronic skin condition. Isotretinoin (Accutane) is the only treatment that can produce long-term remission, but it's reserved for severe cases due to potential side effects.

Does diet affect body acne?

Research suggests that high-glycemic foods (sugary, processed foods) and dairy may worsen acne in some people, though the evidence isn't conclusive for everyone. A balanced diet supports overall skin health, but dietary changes alone are unlikely to clear moderate or severe body acne.

Is body acne contagious?

No. Body acne is not contagious. While bacteria play a role, acne is caused by a combination of factors including your skin's oil production and how your pores work — not by an infection you can pass to others.
