Breakouts & Pores
Chest Acne
Chest acne is acne on the upper chest, often alongside acne on the face, back or shoulders. It forms the same way as facial acne, but sweat, friction and tight clothing make it flare. Several itchy look-alikes, especially fungal acne, are common on the chest too.
- Chest acne is true acne on the trunk, and studies suggest about half of people with facial acne also have acne on the chest or back.
- A benzoyl peroxide wash with a few minutes of contact time, a retinoid and less sweat and friction are the core at-home plan.
- Itchy, uniform chest bumps may be fungal acne or folliculitis instead, and deep or scarring acne needs a dermatologist.
Overview
What is chest acne?
Chest acne is part of what doctors call truncal acne: acne on the chest, back, shoulders and neck. It starts the same way as facial acne. Oil and dead skin cells plug hair follicles, acne bacteria multiply and the follicle becomes inflamed. The result can be blackheads, whiteheads, red bumps, pus-filled spots and, in more severe acne, deep painful lumps.
A 2022 review in the Journal of Clinical Medicine reports that about 48 to 52 percent of people with facial acne also have truncal acne. The same review found the upper back is involved more often than the chest, and lesions tend to cluster near the middle of the trunk. It also notes that truncal acne is often neglected by both patients and clinicians.
Common signs and patterns
What it can look or feel like
These features give context but do not confirm a diagnosis on their own.
Mixed spot types
Blackheads and whiteheads (comedones) alongside red bumps and pus-filled spots of different sizes, often near the breastbone.
Acne elsewhere too
Breakouts on the face, back or shoulders at the same time are a strong hint that chest spots are acne.
Flares with sweat or tight tops
Spots that worsen under sports bras, straps, tight shirts or after sweaty workouts.
Marks or raised scars
Dark or red marks, or firm raised scars, where earlier spots healed.
Causes and contributors
Acne biology drives chest breakouts, and sweat, friction and occlusion add to it.
The trunk shares the same acne triggers as the face: blocked follicles, acne bacteria and inflammation, with hormones such as androgens playing a part. The 2022 review notes that skin on the trunk is more exposed to sweat, pressure, friction and occlusion (being covered and sealed in), which may make acne there worse. The NHS suggests loose, breathable clothing for body acne, especially when you sweat.
Medicines and supplements matter too. The review notes that anabolic steroid use can trigger acne on the trunk. Corticosteroid medicines can cause an acne-like rash called steroid acne, which the review says generally appears after about two weeks of use.
What it may be confused with
Similar-looking concerns need different decisions
The chest is a common site for several acne look-alikes, and some can occur alongside acne.
Fungal acne
Small, itchy, same-sized bumps with no blackheads, mainly on the upper chest and back. It is a yeast problem and needs antifungals.
Folliculitis
Inflamed hair follicles, often from bacteria, shaving, tight clothing or rubbing. Spots sit around hair follicles and may have a red ring, without the blackheads of acne.
Seborrheic dermatitis
A scaly, itchy rash with white to yellowish flakes. The AAD notes it can affect the chest, especially in men. It forms patches, not pimples.
Steroid acne
Red bumps and pustules on the trunk, shoulders and upper arms that start after a steroid medicine. Blackheads, cysts and scars are uncommon.
Bottom line
The bottom line: treat chest acne consistently, reduce sweat and friction, and check the diagnosis if it itches.
Mild to moderate chest acne often improves with the same plan dermatologists use for back acne: a benzoyl peroxide wash, a retinoid and simple clothing and post-workout habits. The AAD says to expect six to eight weeks for a visible difference and three to four months for clearer skin.
Truncal acne often scars, and the 2022 review notes these scars are mainly raised (hypertrophic). Deep, painful or scarring chest acne therefore deserves earlier professional care, as does any chest rash that itches, looks uniform or ignores acne treatment.
Evidence-supported options
Choose the option that matches the cause and severity
This is general education, not a personal treatment plan. Product strengths, permitted uses and prescription status vary by country.
Benzoyl peroxide wash
Kills acne bacteria. The AAD advises leaving the wash on for two to five minutes before rinsing, and notes lower strengths are less likely to irritate. See how to use benzoyl peroxide.
Limit: Can dry the skin, and it bleaches towels, sheets and clothing.
Topical retinoid
A retinoid such as adapalene unclogs follicles, and the AAD notes using it with benzoyl peroxide can improve results.
Limit: Can cause dryness and irritation at first. Retinoids, including adapalene, are avoided in pregnancy.
Sweat and friction control
Showering and changing soon after sweating, and loose cotton or sweat-wicking tops, reduce flares.
Limit: Helps prevent flares but will not clear established acne on its own.
Dermatologist-prescribed treatment
Prescription topicals, oral antibiotics, hormonal treatment or isotretinoin may be used for moderate to severe or scarring acne. A dermatologist can also confirm it is acne.
Limit: Requires medical supervision because of side effects and, for some options, strict pregnancy rules.
Supportive skincare
A simple routine while it is being managed
Consistency matters more than strength, so keep it easy to repeat every day.
Daily
- Benzoyl peroxide washIn the shower, apply the wash to your chest, leave it on for two to five minutes, then rinse well.
- Retinoid at nightAfter showering or at bedtime, apply a thin layer of retinoid to affected areas, as directed.
- Sun protectionUse a broad-spectrum SPF 30 sunscreen labeled non-comedogenic on chest skin that sees the sun, such as a V-neck area.
After sweating
- Shower soonShower as soon as you can after a workout. If you cannot, the AAD suggests an oil-free cleansing wipe.
- Change topsSwap sweaty shirts and sports bras for clean, loose ones made of cotton or sweat-wicking fabric.
- Wash workout kitWash workout clothes after each use, and limit tight straps that press on the chest for hours.
Common mistakes
What can make it harder to manage
- Rinsing a benzoyl peroxide wash off straight away, which gives it little time to work.
- Picking or squeezing chest spots, which raises the risk of marks and raised scars.
- Staying in sweaty clothes, or wearing tight tops that rub and trap heat.
- Treating itchy, uniform chest bumps as acne for months instead of checking for fungal acne.
- Stopping before six to eight weeks, the time the AAD says it takes to see a difference.
When professional help makes sense
See a dermatologist when chest acne is deep, scarring, itchy or not improving
- Deep, painful lumps or cysts under the skin of the chest.
- New raised scars or dark marks forming as spots heal.
- No improvement after six to eight weeks of consistent at-home treatment.
- Itchy, same-sized bumps or a scaly rash that may be fungal acne, folliculitis or seborrheic dermatitis.
- Breakouts that began after a new medicine, supplement or steroid use.

Editorial record
What this page knows, and what remains uncertain
Evidence summary
This page follows AAD self-care guidance for body acne, NHS acne advice and a 2022 peer-reviewed review of truncal acne, with DermNet and the AAD for look-alikes.
Important limitations
Most acne trials study the face, and the review notes that research on truncal acne alone is limited. The AAD wash advice was written for the back and is applied here to the chest because the skin and triggers are similar.
Financial transparency
No paid product placement or affiliate ranking is included on this foundation page.
Recommendation logic
Options move from at-home treatment and prevention to prescription care for more severe acne.

Frequently asked questions
Short answers to common questions
How do you get rid of chest acne?
Use a benzoyl peroxide wash left on for two to five minutes, consider adding a topical retinoid, and shower and change soon after sweating. If there is no improvement after six to eight weeks, see a dermatologist.
Why do I get acne on my chest?
The chest has oil glands and hair follicles like the face, so acne forms there in the same way. Sweat, friction and tight clothing can make it worse, and some medicines and steroids can trigger it.
Is it chest acne or fungal acne?
Fungal acne is itchy, has no blackheads and produces small bumps that look alike. Chest acne usually includes blackheads or whiteheads and spots of different sizes. A dermatologist can confirm which one you have.
Does chest acne leave scars?
It can. A 2022 review notes that acne on the trunk often scars, mostly with raised scars. Treating it early and not picking help lower the risk.
Can sports bras or tight shirts cause chest acne?
They do not cause acne on their own, but sweat, pressure and friction on the trunk may make it worse. Loose, breathable tops and changing soon after exercise can help.
Can I treat chest acne during pregnancy?
Oral isotretinoin must not be used, and topical retinoids are generally avoided in pregnancy. Benzoyl peroxide is usually considered acceptable in limited amounts, but ask your doctor or midwife which options suit you.
