As an esthetician, I notice that some skincare questions come up time and time again, no matter what time of year it is. Alongside how to treat hormonal acne and what to do about enlarged pores, one of the topics clients are often most embarrassed to ask about is bum acne. The reality? It may not be visible, but it’s actually incredibly common.
One of the biggest misconceptions is that every bump on your bottom is actually acne. While it can certainly happen, many cases are caused by something else entirely, which is why copying your facial acne routine onto your body doesn’t always deliver the results you’re hoping for. Identifying what’s really going on is the first—and arguably most important—step towards clearer skin.
The good news is that once you understand the cause, bum breakouts are often very manageable. A few targeted skincare ingredients, some simple tweaks to your daily routine and avoiding some common mistakes can make a noticeable difference. And as with most skin concerns, consistency is far more important than reaching for the strongest treatment you can find.
Ahead, dermatologist Sonia Khorana has helped me to answer the questions I’m asked most frequently by clients, from what actually causes bum acne to the ingredients that are genuinely worth using and the everyday habits that could be making flare-ups better—or worse.
What Causes Bum Acne?
The first thing I explain to clients is that what they’re calling “bum acne” often isn’t acne at all. According to Khorana, “It’s important to remember, it may not be true acne.” In many cases, the culprit is actually folliculitis—an inflammation of the hair follicles that’s commonly triggered by bacteria, yeast, sweat, or friction. It tends to appear as small red bumps, sometimes with a whitehead, clustered around individual hair follicles.
Another common possibility is keratosis pilaris (KP), which Khorana explains is “caused by a buildup of keratin that plugs hair follicles. It’s harmless and isn’t caused by poor hygiene.” These bumps are typically rougher, flesh-coloured and less inflamed than acne.
With that said, true acne can develop on the buttocks too. “When true acne does occur on the buttocks, it develops in the same way as facial acne, with a combination of excess oil, dead skin cells, and bacteria clogging the pores,” says Khorana. Although this is less common than on the face or back due to there being fewer oil glands in the area, it does happen.
The type of bumps you’re experiencing can also offer clues. Folliculitis usually presents as red papules and pus-filled pustules around hair follicles, while true acne is more likely to include blackheads, whiteheads, and inflamed pimples. If you’re noticing painful boils, recurring lumps, or tunnels beneath the skin, Khorana advises seeking medical advice, as this could indicate another condition, such as hidradenitis suppurativa. Ultimately, identifying the underlying cause is key, as the right treatment depends entirely on what’s causing the bumps in the first place.
What Products Are Best for Butt Acne?
For inflamed folliculitis or true acne, Khorana recommends a body wash containing benzoyl peroxide. As she explains, “A body wash containing benzoyl peroxide can help reduce bacteria on the skin and is often useful for inflamed or pustular breakouts.” I often recommend leaving it on the skin for a minute or two before rinsing to maximise its effectiveness, but it’s worth remembering that benzoyl peroxide can bleach towels and clothing if not thoroughly rinsed off.
Another ingredient I regularly recommend is salicylic acid. Khorana explains, “Exfoliating ingredients such as salicylic acid help to keep follicles clear by dissolving oil and debris within the pore,” while AHAs such as glycolic acid and lactic acid “gently exfoliate and give you smoother skin texture over time.” If the bumps are actually keratosis pilaris rather than acne, she recommends urea-based body lotions, explaining that they’re “helpful for softening rough, bumpy skin and reducing keratin build-up.” I also encourage clients to choose fragrance-free, non-comedogenic moisturisers to support the skin barrier without clogging follicles. Above all, I couldn’t agree more with Khorana’s final piece of advice: “Ultimately, consistency matters more than intensity.”
What Helps Butt Acne?
In my experience, the products you use are only one part of the picture. Lifestyle habits can have just as much influence on whether bum breakouts improve or keep coming back, particularly if the underlying cause is folliculitis rather than true acne.
According to Khorana, “Lifestyle habits play a big role in either triggering or helping to prevent ‘bum acne,’ which is most often related to folliculitis rather than true acne.” She explains that “staying in sweaty workout clothes for too long, wearing tight or non-breathable fabrics, prolonged sitting (which increases heat and friction), and not showering soon after exercise” can all create “an environment of warmth, moisture, and friction that can irritate hair follicles and encourage breakouts.” These are some of the most common triggers I discuss with clients, particularly those who exercise regularly or spend long periods sitting at a desk.
Fortunately, a few simple changes can make a noticeable difference. Khorana advises “showering immediately after sweating, wearing loose, breathable clothing, regularly changing out of damp clothes, and gently exfoliating a few times a week to prevent buildup of dead skin cells” to help minimise flare-ups. Ultimately, it’s these small, consistent habits that make the biggest difference over time.

1. Topicals Clearly Acne Body Mist
Topicals
Clearly Acne Body Mist
Pros
- Convenient spray format for hard-to-reach areas
- Lightweight, fast-absorbing formula
- Easy to use consistently
Cons
- Results take time and consistency
- Can feel slightly drying if overused
If you’re dealing with breakouts in areas that are difficult to treat (i.e., your bum), a mist format can be a game-changer—and this is one of the most effective I’ve tried. It uses a blend of exfoliating and antibacterial ingredients to help clear existing blemishes, prevent new ones from forming, and improve the appearance of post-acne marks over time. I love that it’s so easy to incorporate into a routine: simply spray it onto clean, dry skin and let it absorb without any rubbing or mess. It feels lightweight and refreshing rather than like a traditional acne treatment, making it much easier to stay consistent with.
2. Naturium The Energiser Mandelic Acid Body Wash
Naturium
The Energiser Mandelic Acid Body Wash
Pros
- Gentle enough for regular use
- Mandelic acid helps smooth rough skin
- Doesn’t strip the skin barrier
Cons
- Improvements can be gradual
- May not tackle severe inflammatory acne alone
Mandelic acid is one of my favourite ingredients for body breakouts because it’s effective without being overly aggressive, and this cleanser showcases exactly why. It gently lifts away dead skin cells and helps keep hair follicles clear, making it particularly useful if your bumps are caused by congestion or folliculitis. I also appreciate that it creates a satisfying lather without leaving my skin feeling squeaky clean or uncomfortable afterwards. Over time, I’ve found it helps smooth rough texture as well as reduce the frequency of flare-ups.
3. Dr Sam’s Flawless Neutralising Gel Roller
Dr Sam’s
Flawless Neutralising Gel Roller
Pros
- Convenient roll-on application
- Lightweight, fast-absorbing formula
- Helps calm inflamed spots
- Doesn’t feel sticky
One of the biggest advantages of this treatment is how easy it is to use. The roll-on applicator makes it simple to target individual areas without getting product all over your hands, and the lightweight gel absorbs almost instantly without leaving any sticky residue. I like using it after showering on areas that are prone to recurring breakouts, and it’s particularly good at calming angry, inflamed spots before they fully develop. It layers well underneath moisturiser too, making it easy to slot into your existing bodycare routine.
4. Dermalogica Breakout Clearing Booster
Dermalogica
Breakout Clearing Booster
Pros
- Helps reduce redness quickly
- Lightweight gel texture
- Layers well with other skincare
Cons
- Not designed for treating large areas
Whenever I feel a deeper spot starting to develop, this is the treatment I reach for. The concentrated gel delivers active ingredients directly where they’re needed, helping reduce redness and congestion without drying out the surrounding skin. It can be used on both face and body—I find it works particularly well on stubborn individual blemishes that seem determined to linger. Because a little goes a long way, one tube also lasts surprisingly well.
5. Clinisoothe Skin Purifier
Clinisoothe
Skin Purifier
Pros
- Extremely gentle and suitable for sensitive skin
- Helps calm redness and irritation
- Affordable price point
Cons
- Only available online
- Won’t exfoliate clogged pores or rough texture
If your skin is easily irritated or you find traditional acne treatments too harsh, this is a brilliant alternative. Rather than relying on exfoliating acids, this gentle hypochlorous acid mist works to support the skin’s natural defences, helping to calm redness, reduce irritation, and keep bacteria levels balanced. I particularly like it after workouts, shaving, or whenever my skin feels more reactive, as it feels instantly refreshing without any stinging or dryness. It’s not an overnight quick fix, but with consistent use it can help create a healthier skin environment that’s less prone to recurring flare-ups.
6. The Inkey List PHA Body Water Cream
The INKEY List
PHA Body Water Cream
Pros
- Lightweight and non-greasy
- Hydrates while gently exfoliating
- Affordable price point
Cons
- Too gentle for severe breakouts on its own
Many people skip moisturiser when treating body acne, but I always recommend using one—and this formula is ideal. The lightweight cream combines hydrating ingredients with PHAs, so you’re gently exfoliating while supporting the skin barrier at the same time. I love how quickly it absorbs and that it doesn’t leave any greasy residue behind, making it easy to use every day. With regular application, it leaves skin noticeably smoother and softer while helping reduce the rough, congested texture that can lead to breakouts.
7. Hero Mighty Patch Surface Spot Patches
Hero
Mighty Patch Surface Spot Patches
Pros
- Large patches cover multiple spots
- Helps prevent picking
- Protects skin from friction
Cons
- Less effective on deep cystic spots or spots without a head
Spot patches aren’t just for your face, and these oversized versions are brilliant for treating larger areas of congestion. I like applying them overnight to inflamed spots because they help protect the area from friction while drawing out excess fluid from blemishes. They also prevent picking, which is often the biggest obstacle to healing. By morning, spots look flatter, calmer and less irritated.
8. Rituals The Ritual of Hammam Body Mud
Rituals
The Ritual of Hammam Body Mud
Pros
- Excellent weekly detox treatment
- Helps absorb excess oil
- Leaves skin feeling smooth
- Spa-like application experience
Cons
- Can be messy to apply
- Needs time to work
I don’t think body masks get nearly enough attention, and this is one I frequently recommend to anyone struggling with congestion on their body. The mineral-rich clay helps absorb excess oil and impurities while leaving skin feeling incredibly clean and refreshed. I like using it once a week as a deeper treatment when my skin feels particularly congested, and it always leaves the area looking smoother (as well as clearer) afterwards.
9. Cosmetic Consult Miracle Body Transformation
Cosmetic Consult
Miracle Body Transformation
Pros
- Improves both breakouts and post-acne marks
- Leaves skin noticeably smoother
- Powerful blend of exfoliating acids
- Helps prevent future congestion
Cons
- Can tingle on sensitive skin
- Requires daily SPF on exposed areas
If texture and dullness are as much of a concern as active breakouts, this treatment is a great multitasker. It combines a blend of chemical exfoliants to smooth rough skin, fade post-inflammatory marks and help prevent new congestion from forming. I notice my skin feels noticeably softer and looks brighter when I use these regularly, but it’s the long-term improvement in clarity and texture that really stands out. Despite the powerful formula, it doesn’t feel overly harsh when introduced gradually into your routine.
