A large, red, hot, and painful bump that appears on a buttock is rarely acne. In the vast majority of cases, it is deep folliculitis or a boil: an inflammation of the hair follicle, exacerbated by friction, sweat, and maceration, and sometimes complicated by a bacterial infection.
With the right steps, you can find relief—and, most importantly, prevent the problem. And as part of your daily routine, using a cleansing product for your buttocks helps minimize breakouts and keep your skin clear. Here’s an overview, with no taboos: what it is, how to respond, and the warning signs that indicate you should seek medical advice.
Key Takeaways
- A large pimple on the buttocks is most often deep folliculitis or a boil, not acne.
- It's the same equation every time: friction + heat + humidity + a weakened hair follicle.
- Never pop a boil: it can lead to a widespread infection and scarring.
- Fever, severe pain, pus, or recurring symptoms → see a doctor.
- In daily life: gentle cleansing, cotton, moisturizing, and targeted care help prevent recurrence.
What is that big pimple on my butt?
The skin on the buttocks is thicker than that on the face, but it spends its days squeezed between jeans, a chair, and sweat. What we call a “big pimple” is actually a collection of several distinct lesions, and the right treatment depends on correctly identifying them.
Deep folliculitis
The hair follicle becomes inflamed and forms a red pimple centered around a hair, sometimes topped with a white head, that is tender to the touch. Most often caused by bacteria, it can affect several neighboring follicles and result in a cluster of pimples. Friction, heat, and a damp swimsuit can cause it to persist.
A boil on the buttocks
When the infection spreads deeper into the skin, the follicle forms a boil: a red, hard, very painful lesion that swells over the course of a few days and then develops a white head of pus. A single boil often heals on its own within one to two weeks. However, multiple boils clustered together (anthrax), recurring boils (furunculosis), or a fever require medical attention. And in any case, you should never lance it yourself.
What Not to Confuse
Not all lumps on the buttocks are pimples. An ingrown hair forms a small red lump around a hair that grows back under the skin—a common occurrence after shaving or hair removal—see our tips on ingrown hairs. A sebaceous cyst is a soft lump that is painless unless it becomes inflamed. Painful, recurring nodules in skin folds may indicate Verneuil’s disease, which should be evaluated by a dermatologist. If in doubt, only a clinical examination can provide a definitive diagnosis.
What about those rough little bumps or blackheads?
If they are dry, flesh-colored, and painless, it is more likely to be keratosis pilaris. If there are comedones and blackheads, it is body acne, such as back acne: two separate conditions that are less “severe” and painless.
Why do these big pimples appear?
The number one cause remains mechanical: the friction caused by tight clothing and synthetic fabrics against damp skin weakens the hair follicle and triggers inflammation. Sweat, summer heat, and keeping workout clothes on after exercise contribute to maceration, which allows bacteria to multiply. Improper hygiene does the rest: too little encourages bacterial growth, while too aggressive a routine destroys the skin barrier. For details on all the triggers, see the causes of butt acne.
How do you treat a big pimple on your butt?
How to Soothe a Painful Pimple Right Away
For an isolated lesion: do not lance it, and do not squeeze it. A cold compress applied for a few minutes soothes redness and discomfort; conversely, a warm compress applied several times a day helps a mature boil to drain on its own. A mild antiseptic on the affected skin, a zinc oxide paste to isolate the area, loose-fitting cotton clothing, and sitting on it as little as possible: these measures will provide relief while you wait for it to go away.
The Endurance Routine
To prevent breakouts, follow this simple routine: gently cleanse with a moisturizing soap and lukewarm water, exfoliate once or twice a week (lactic acid for sensitive skin, salicylic acid for oily skin), and then moisturize daily. You’ll find all the details in our tips for getting rid of pimples on your buttocks. For targeted care, Fesse Time combines lactic acid, peppermint, jojoba, and shea butter to smooth and soothe the skin’s texture, both on the buttocks and the rest of the body.
Medical treatments (benzoyl peroxide, antibiotics, drainage, laser)
They are prescribed after a diagnosis: they shouldn't be taken without a doctor's advice, and you should never reuse an antibiotic prescribed to a family member.
Natural Remedies: What Helps, What Irritates
A few remedies are truly effective: aloe vera gel soothes and moisturizes; tea tree oil, which is antibacterial, should only be used diluted—never undiluted—and never on children or pregnant women; a gentle exfoliation with fine sugar once a week on unbroken skin. Conversely, baking soda disrupts the skin’s pH balance, coconut oil clogs pores, and lemon makes the skin more sensitive to sunlight. No home remedy can replace medical treatment for an established infection.
When should you see a doctor or a dermatologist?
Cosmetics are designed for healthy skin or skin with minor imperfections; they do not treat infections. Make an appointment if:
- the lump is very painful, warm, swollen, or accompanied by a fever;
- there is pus, multiple clustered lesions, or rapid spread;
- The pimples persist for more than a few weeks despite following a proper skincare routine;
- recurrences occur one after another (furunculosis, chronic folliculitis);
- deep nodules or scars appear, especially in skin folds;
- you have diabetes or a weakened immune system, because the risk of complications is higher;
- the lesion looks unusual or is located in the genital area.
The doctor performs a clinical examination, sometimes takes a sample, and adjusts the treatment: antiseptic, antibiotic, antifungal medication, drainage of a boil, or laser treatment in cases of recurrent folliculitis.
How can you prevent large diaper rash bumps?

- Exfoliate once a week, moisturize every day.
- Get up regularly when working in a seated position.
FAQ
How do you treat large pimples on your buttocks?
Gentle daily cleansing, regular exfoliation (with salicylic acid or lactic acid), noncomedogenic moisturizer, and a body treatment for blemishes. If you have an infected or persistent lesion, consult a dermatologist to receive appropriate treatment.

Clean the area with mild soap, apply a cold compress for a few minutes, then apply a light moisturizer. Wear loose-fitting cotton clothing and never pierce the area.
