Acne most often affects body sites that have a lot of oil glands. These sites include the:

  • neck
  • chest
  • shoulders

Folliculitis refers to a common skin infection in hair follicles.

Folliculitis typically appears like an acne breakout. However, the red ring around the bumps is a sign of the infection. It is generally the result of damage to the hair follicles. After damage occurs, it is easier for germs to get inside them and then cause an infection.

Common ways to cause damage to your hair follicles include:

  • rubbing your skin frequently
  • wearing tight clothing
  • skin rubbing against skin
  • shaving

Spending time in a hot tub is also a common cause of folliculitis. Many people notice a breakout within 24–48 hours of using a hot tub.


Carbuncles are a group of boils with more than one head. Since carbuncles are the result of an infection of the hair follicle that spreads to the surrounding skin and tissue, they are often contagious.

A boil is a form of bacterial folliculitis. It typically appears as a single or multiple tender spots, lumps, or pustules. They are often red in color but this can depend on your skin tone.

  • Allergic: This type is a delayed reaction that occurs 1–2 days after your skin comes into contact with an allergen. One common example of this is poison ivy rash.

Contact dermatitis presents as a rash that is irritated. On light skin, it may appear red, and on dark skin, it may appear dark brown, purple, or gray.

What are the treatments for butt acne?

Butt acne treatment depends on the underlying cause.

Since many of the causes are not actually acne, acne products are not likely to work. In fact, they may make it worse. If you are not sure of the cause, contact your doctor for help developing a treatment plan.

Keratosis pilaris

If it is the result of keratosis pilaris, you most likely have similar bumps on the back of the upper arms or thighs. Moisturizing the affected areas right after showering can help soften the skin.

An exfoliant cream containing lactic acid or similar ingredients can encourage the skin to turn over faster and prevent plugged follicles.

For keratosis pilaris, products containing lanolin, glycerin, or petroleum jelly are often effective treatments. Keeping the skin soft can help prevent keratin buildup. Using an over-the-counter exfoliant cream can help encourage skin turnover to keep follicles from clogging.

Look for ingredients such as lactic acid, salicylic acid, urea, alpha hydroxy acid, or adapalene. In some cases, prescription-strength retinoid creams may be necessary.

Other home remedies include the following tips.

  • Avoid harsh cleansers and soaps and vigorous scrubbing or rubbing. Gentle exfoliation and mild cleansers are less irritating to the skin. Remember to pat the skin dry instead of rubbing it.
  • Bathe with warm water for the shortest time possible. Long showers or baths and hot water can dry out the skin, making keratosis pilaris worse.
  • Use a humidifier during the dry winter months.
  • Wear loose clothing to avoid friction.


For folliculitis, it is important to avoid whatever is causing the breakout. This may include:

  • wearing loose clothing instead of tight
  • changing out of wet or damp clothing immediately
  • not using hot tubs or whirlpools

Contacting a dermatologist is often helpful to understand what behaviors you may need to change. A dermatologist can also prescribe treatment for any infection that is present. This may include antibiotic creams or lotions.

Other remedies for folliculitis include:

  • applying warm, moist compresses several times per day
  • using soothing, anti-itch lotions
  • using an antibacterial soap or cleanser
  • washing towels and washcloths in hot water and changing them after each use

Because treatment varies depending on the underlying causes, you should contact your doctor about the best way to treat your butt acne.


Butt acne is typically the result of an underlying condition, such as keratosis pilaris or folliculitis. Occasionally, it is actually acne. However, this is not very common.

Most of the causes of butt acne are treatable. If you are experiencing butt acne, you should contact your doctor so that they can diagnose the underlying condition causing the breakouts.
