Sometimes you might catch yourself noticing a nasty pimple not on your face but on your backside. For some, it’s rare; for others, more frequent. Chances are, we’ve all encountered that painful bump on our butt—a real nuisance that can even hurt at times.
Butt Pimples Aren’t Your Typical Acne
Dr. Joshua Zeichner, a dermatologist and director of cosmetic and clinical research at Mount Sinai Hospital in New York, explains that bumps on the butt usually aren’t classified as acne or pimples. While pimples can appear on the backside, they’re quite rare. Dr. Jamie MacKelfresh, an associate professor of dermatology at Emory University School of Medicine in Atlanta, agrees—the structure and look of butt acne differ from the classic pimples you see on your back, chest, or face.
Acne typically shows up on the face, neck, shoulders, chest, or back due to clogged pores. It’s caused partly by trapped oil in hair follicles, and when bacteria multiply, inflammation can follow.
But those bumps on your butt have different causes. Some believe tight, clingy clothes contribute because they don’t let your skin breathe. This can lead to irritation, discomfort, and skin problems.
The situation worsens when the area gets moist, like during workouts when sweat and friction cause irritation. This makes your butt more prone to those annoying bumps. There are also other reasons behind these bumps, which we can categorize as follows:
Folliculitis (Inflamed Hair Follicles)
Folliculitis can quickly cause acne-like bumps on your butt. It’s an infection caused by yeast, bacteria, or fungi, or by clogged or irritated hair follicles. These shallow bumps can itch and hurt in the affected area.
This usually develops due to friction between clothing and skin, combined with heavy sweating, which disrupts the skin’s surface and leads to those pimple-like bumps.
The problem often clears up on its own, but if it doesn’t, antibacterial washes prescribed by a doctor, and sometimes antibiotics or antifungal treatments, can help.
Carbuncle or Boil
If folliculitis is untreated or worsens, it can lead to deeper infections like carbuncles or boils. These can cause scarring if not recognized and treated properly. Because this is a deeper issue, it requires more serious care.
Often, treatment involves antibiotics and a minor procedure where a doctor safely drains the wound to release pus.
Afterward, the wound is covered with a dressing. It’s very important never to try draining a boil yourself—it can cause more harm than good. Always trust a professional to handle it!
Keratosis Pilaris (Chicken Skin)
Keratosis pilaris, often called “chicken skin,” is a painless skin condition that causes rough patches and small bumps resembling pimples. Experts say it happens when keratin, a protective protein in the skin, blocks hair follicles. It can also appear alongside other skin conditions. Since it doesn’t hurt, many don’t treat it. If it bothers you, moisturizing creams and ointments for dry patches can help. Many consider “chicken skin” on the butt just a normal skin variation and leave it as is.
Allergic Reactions
Often, bumps on the butt come from allergic reactions. For example, if you’re sensitive to wet wipes, friction combined with chemical preservatives in some products can cause contact dermatitis. This shows up as bumps and irritating spots on your backside. If you notice this, it’s best to avoid the triggering product until your skin clears up.
You Can Totally Prevent These Skin Issues
Dr. Jamie MacKelfresh believes those annoying bumps on your butt can be prevented by simple precautions and paying attention to your skin’s health. Wear loose clothing to reduce sweat and friction from tight fabrics, which can irritate your skin.
We’re not saying you need to wear shirts three sizes too big or swap your size S pants for L, but try to avoid very tight, skin-hugging clothes.
After working out, always shower and change into clean clothes to prevent bacteria from thriving. Experts recommend using a clean towel every time you bathe. (Of course, you don’t need a fresh towel every night, but that’s the ideal for full hygiene).
If that’s not your style, at least change towels twice a week. Avoid wet wipes, especially those with strong fragrances. This helps keep your skin healthy and reduces the chance of those annoying bumps on your butt.
