Pimples can pop up anywhere on the skin, from your scalp to your butt (yes, buttne is a thing!) and on your chest. When it comes to breakouts on the chest, excess oil, sweat and clothing are just a few of the potential culprits. Below, we’re sharing seven potential causes of chest acne and the best products to treat the breakouts, with recommendations from Dr. Marisa Garshick, a board-certified dermatologist and consultant based in New York City.

What Causes Chest Acne?

Excessive Sweating

One of the most common reasons for chest acne is sweat that’s been lingering on the skin for prolonged periods of time, whether it be due to exercise or heat. When sweat mixes with existing dirt, toxins and oil on the skin’s surface, it can clog the pores, resulting in chest acne. It’s recommended to shower or, at the very least, rinse off within ten minutes of exercise or excessive sweating.

A Reaction to Synthetic Materials or Fabrics

Ill-fitting clothing or clothing made of irritating materials can lead to acne, especially if the skin is particularly sensitive. Acne mechanica is the result of materials or objects touching your skin and causing a breakout. The skin condition can also be aggravated by moisture, so if you’re sweating while wearing clothing that doesn’t breathe, you’ll be more prone to breakouts. Look for clothing in loose, lightweight and natural (aka not synthetic) materials for maximum breathability. Similarly, your chest acne could be the result of an allergic reaction to a new detergent or cleaning product used on your clothing or sheets. When in doubt, consult a dermatologist.

Hormonal Changes

Any major hormonal changes (think: puberty, periods and pregnancy) or fluctuations in the body can send our oil-producing sebaceous glands into overdrive. This can clog pores and potentially lead to chest pimples. If you’re noticing changes in your hormones, talk to a doctor.

Touching Your Chest

We’ve heard it over and over again: Don’t touch your skin! Our fingertips are covered in oil and bacteria that can transfer onto the chest. Before you apply any skincare products to your chest, make sure you wash your hands first.

Hypersecretion of Oil

When your skin is dry, whether because of wind, cool temperatures or prolonged sun exposure, it can start to produce excess oil in order to compensate for the loss of moisture. When excess oil mixes with dead skin cells, bacteria, dirt and debris, it can cause acne. That’s why it’s important to apply hydrating products on your neck and chest during your morning and nighttime skincare routines.


There are certain irregularities in types of genes that can cause an increased chance in getting acne. If your parents have a history of struggling with acne, whether on the chest or elsewhere, you may be more likely to experience the same skincare issue.

Your Skincare and Makeup Products

The same way your skin can react to certain fabrics or detergents, beauty products can also cause breakouts. Depending on their ingredients, some products have a higher likelihood of clogging pores and causing breakouts than others.


When shopping for new body lotions, moisturizers or concealers, look for ones with any of these keywords on the label: non-comedogenic, non-acnegenic, oil-free and “won’t clog pores.”  

How to Prevent Chest Acne

In addition to identifying the causes above, there are several skincare practices you can incorporate to reduce your chance of chest acne. “When it comes to chest acne, it can be especially important to wash the skin regularly, especially after sweating or exercise to prevent clogged pores,” says Dr. Garshick. “It can also help to use an acne wash containing ingredients such as salicylic acid or benzoyl peroxide.” 


In addition to using acne-fighting body washes, Dr. Garshick stresses the importance of using non-comedogenic body-care products, such as lotions and moisturizers. Non-comedogenic formulas help prevent clogged pores, which reduces your skin’s chance of breaking out. Regular exfoliation can help unclog pores as well — Dr. Garshick recommends exfoliating your skin once a week.

How to Get Rid of Chest Acne

Again, Dr. Garshick says that one of the best ways to get rid of chest acne is to regularly cleanse your skin, especially if you’ve been sweating. This will prevent sweat and grime from clogging your pores. In addition to regular showers and cleansing, Dr. Garshick says that anti-acne ingredients like benzoyl peroxide, salicylic acid and retinoids can all help lessen and eliminate chest acne. In some cases, she says, your dermatologist may write you a prescription for certain oral or topical acne medications.

How to Get Rid of Chest Acne Scars

First things first: If you have chest acne, do your best not to pick at or pop it. Doing so can increase inflammation and up your chance of scarring. If you’ve already picked at the spots, or you have deep breakouts that led to scars, there are a few fixes you can try at home or in a dermatologist’s office. “Acne scarring on the chest can be treated with retinol [and] gentle exfoliants, including in-office chemical peels and lasers,” says Dr. Garshick. “It is important to remember that the skin on the chest is delicate so it is important to not be too aggressive with treatments on the chest.”

Versed Press Restart Gentle Retinol Body Lotion

You might know about retinol’s benefits for your face — not only can it help soften fine lines and wrinkles, it also increases cell turnover to unclog pores, reduce breakouts and fade the look of acne scars. Those same benefits extend to your body too. Instead of wasting precious drops of your favorite retinol face serum, try applying this retinol-infused body lotion after you shower. Just be aware that retinol can increase your skin’s sensitivity to the sun, which makes it extra important to apply and reapply SPF 30 or higher to any exposed skin.
