Summer brings lighter clothes, bare arms, and all the little details we usually don’t think about during colder months. If you’ve ever noticed small, rough bumps on the backs of your arms, thighs, or butt, you’re definitely not alone. That’s keratosis pilaris, an incredibly common, totally harmless skin condition that many people quietly deal with. The good news? While it can be stubborn, it’s also very manageable. With the right gentle care, your skin can feel smoother, softer, and much more comfortable in its own texture.
What Is Keratosis Pilaris?
Keratosis pilaris (hereinafter referred to as KP) happens when the skin’s natural shedding process gets stuck. Keratin, a tough protective protein your skin produces, builds up inside hair follicles instead of shedding normally, forming a plug. That plug pushes up through the skin surface as a small, hard bump. Multiply that across hundreds of follicles, and you get the rough, uneven texture that’s become known colloquially as “chicken skin.”
The bumps are usually white or reddish. On some skin tones, particularly deeper ones, KP can also appear mainly as flat reddish or brownish discoloration without a pronounced bump, which makes it easy to mistake for something else entirely. After bumps are irritated (from picking, scrubbing, or friction), they can leave behind post-inflammatory hyperpigmentation that lingers long after the bump itself has settled.
One of the most recognizable signs of KP is that it’s always symmetrical. If it appears on one arm, it’ll show up on the other. Same with the thighs or any other area.
KP most commonly develops on the upper arms, thighs, and buttocks. Still, it can occasionally appear on the face, where it’s often mistaken for persistent redness or stubborn small pimples around the cheeks.
The exact cause isn’t fully understood, but the pattern is clear: KP is genetic. It runs in families, and people with eczema, asthma, or seasonal allergies are significantly more likely to develop it. It tends to affect children and teenagers most, often improving with age. Still, for many people, it persists well into adulthood. Dry skin makes it visibly worse, which is why it often flares in winter and calms down in summer when humidity is higher.
KP is genetic, which means you can’t make it disappear permanently. Still, you absolutely can make it look and feel dramatically better with the right care.
Common Keratosis Pilaris Mistakes to Avoid
Before getting into what works, it’s worth knowing what makes keratosis pilaris worse, because some common instincts actually backfire.
Bar soap may be harsh. Soap strips the skin of lipids and amino acids that keep the skin barrier intact. When that barrier is compromised, moisture escapes more easily, skin gets drier, and dead cells are more likely to clog follicles. If your skin feels squeaky clean after washing, that’s not a good sign. That’s your barrier being damaged. Switch to a gentle, fragrance-free body wash instead.
Physical scrubs can irritate. It’s tempting to try to sand those bumps off, but rough scrubs only irritate the skin surface without addressing what’s happening deeper in the follicle. Worse, they can cause inflammation, making KP more noticeable. If you want to use something physical, a soft washcloth or gentle exfoliating mitt is the most you should reach for.
Picking may worsen discoloration. They’re not pimples. Picking leads to inflammation, potential scarring, and post-inflammatory hyperpigmentation: brown marks that can stick around long after the original bump is gone.
Hot water may aggravate KP. Water, especially hot water, is drying. It disrupts the skin barrier in the same way soap does. Keep showers short, use lukewarm water, and pat skin dry rather than rubbing.
Hair removal may irritate the skin. Shaving, waxing, and epilating can all irritate KP-prone skin, trigger inflammation, and make the texture and redness more pronounced. If you do need to remove hair in those areas, be extra gentle and follow up immediately with hydration.
How to Get Rid of Keratosis Pilaris: Treatment Guide
Chemical exfoliation is the most effective tool you have. Specifically, BHA (salicylic acid) is the gold standard for KP because it’s oil-soluble, meaning it can penetrate into the hair follicle, which is exactly where the problem is. It helps normalize the skin’s natural shedding process, clears out the keratin buildup, and has anti-inflammatory properties that calm irritation. Look for a BHA exfoliant with a pH between 3.2 and 3.9 for it to work properly, and use it two to three times a week on affected areas.
If BHA alone isn’t giving you enough improvement, or if it doesn’t work for you, AHA acids (like glycolic acid or lactic acid) are worth trying. AHAs work more on the skin’s surface, helping slough off dead cells and improve texture. You can also alternate: BHA one evening, AHA the next. Some people find the combination more effective than either acid alone.
Use a gentle, non-stripping body wash. Fragrance-free, soap-free formulas are your safest bet. The oil-based cleansers you’ll often find at the pharmacy work well for KP-prone skin: they clean without disrupting the skin barrier.
Moisturize consistently, and choose the right texture. Hydration is critical for KP because dry skin makes the condition significantly more visible. But not all moisturizers are created equal here: heavy, occlusive creams can actually clog follicles and worsen KP. Instead, reach for lightweight lotions or serums with ingredients like hyaluronic acid, glycerin, or ceramides. Apply your moisturizer right after the shower, while skin is still slightly damp, to lock in hydration. Evening application works best.
If KP shows up on your face, the same principles apply. Just use face-appropriate products. A facial BHA exfoliant, a gentle cleanser, and a lightweight moisturizer are the core steps. For stubborn facial KP, ingredients like retinoids or azelaic acid can help support healthy skin cell turnover and improve the texture over time.
Consider a humidifier. Especially in winter, dry indoor air makes KP noticeably worse. Running a humidifier in your bedroom adds moisture back into the environment. It takes some pressure off your skin barrier, a simple change that can genuinely make a difference.
When to See a Dermatologist for Keratosis Pilaris
If you’ve been consistent with a good skincare routine for a few months and aren’t seeing meaningful improvement, it’s worth talking to a dermatologist. Laser and light-based treatments, including IPL (intense pulsed light) and Nd:YAG laser, may help improve the appearance of keratosis pilaris, especially redness and skin texture. Results can vary depending on the individual and the severity of KP. These treatments are also effective at fading the post-inflammatory brown spots that sometimes develop after the bumps are irritated. A derm can help you figure out whether in-office treatment makes sense for your skin.
Final Thoughts
Keratosis pilaris can be annoying, but it doesn’t define how you feel in your skin. Summer isn’t about perfect texture; it’s about feeling light, comfortable, and free in whatever you’re wearing. With a bit of gentle care, your skin can feel calmer and smoother, but don’t let a few bumps take up space in your head. Wear a tank top, jump in the water, and enjoy the sun! Your skin doesn’t need to be perfect to be part of the season.
