Keratosis pilaris (aka “KP”) is a common, harmless skin condition that, like stubborn acne breakouts, often leaves people desperate for solutions. Much of the confusion comes down to nuance (To exfoliate or not? Chemical exfoliants or physical scrubs? Treat it or let it be?), and Reddit threads run deep with tips that have brought sufferers real relief, though not everyone is so lucky—which makes sense, given how common KP actually is. According to the Cleveland Clinic, KP affects around 40 percent of adults, meaning it’s likely affecting someone you know, or even you.
So what is keratosis pilaris, actually? According to New York dermatologist Michelle Henry, MD, KP occurs when keratin—a protein that normally shields skin from infections, irritants and UV damage—builds up around hair follicles instead of shedding properly, creating rough, small bumps most commonly on the back of the arms (though it can also appear elsewhere, including, less commonly, under the breasts).
KP’s exact cause remains unknown, but genetics are thought to play a role. “It runs fairly strong in families,” says Omaha, NE dermatologist Joel Schlessinger, MD, adding that it also tends to worsen after pregnancy and during growth spurts. A compromised skin barrier is another trigger, according to Davie, FL dermatologist Marianna Blyumin-Karasik, MD, which is why KP so often shows up alongside eczema and other chronic skin conditions. The bumps are generally painless, though they can sometimes become inflamed, itchy or very red.

In-Office Treatments for Keratosis Pilaris
For those ready to go beyond drugstore products, dermatologists’ offices offer a more heavy-duty arsenal. Dr. Henry suggests microdermabrasion, which physically buffs away the outer layer of dead skin. West Palm Beach, FL dermatologist Jacob Beer, MD, meanwhile, tends to favor chemical peels—about once a month, with real improvement typically visible after two to three sessions. “Prescription retinoids can also be helpful but will take some time,” he adds. For lingering redness specifically, he turns to pulse dye laser.
Even after your KP clears up, it can leave discoloration behind. “Some of the post-inflammatory hyperpigmentation can be improved gradually,” says Dr. Beer, who typically turns to resurfacing treatments or pigmentary lasers on low settings. Treatment isn’t one-size-fits-all, though: Results and settings vary by skin tone, and patients with darker skin, for instance, may develop lighter spots that call for a different approach.
How to Treat Keratosis Pilaris at Home
If you’re going the DIY route, gentleness matters most. New York dermatologist Elaine Kung, MD, steers her patients away from physical exfoliation altogether, explaining that scrubbing can lead to lichen amyloidosis, a condition marked by hardening and discoloration around hair follicles.

Dr. Beer points to salicylic acid as a strong first step (just don’t overdo it, since it can be irritating with frequent use.) Lactic acid (often labeled 12 percent ammonium lactate) and 20 percent urea cream are two more favorites, doing double duty as both exfoliants and moisturizers. Glycolic acid tends to be gentler on skin, a good option if yours runs sensitive. And if you’re looking for a long-term fix, retinoids offer the best results—they just take longer to work, and can cause some irritation in the beginning.
A simple place to start, per Dr. Beer: a salicylic acid wash two to three times a week, plus a daily lotion with 12 percent ammonium lactate or 20 percent urea. While some people may need a prescription-strength option or in-office treatment to see real change, for many, an over-the-counter, at-home routine is enough to make a noticeable difference.
Does Hypochlorous Acid Help with Keratosis Pilaris?
Hypochlorous acid has come up as a potential fix for KP, but Dr. Beer isn’t convinced it’s doing much. “Hypochlorous acid is helpful as an antiseptic and is somewhat anti-inflammatory, but overall there’s very little mechanistically as to why it would help with keratosis pilaris,” he says. “It doesn’t help with the abnormal keratinization or the hair follicle problem. It may help minimally on inflammation. I think it’s mostly a social media trend.”

As with any new addition to your routine, check with your dermatologist on frequency, especially if you’re layering it with other exfoliating treatments.
Best Keratosis Pilaris Products, According to Dermatologists
1 / 7
This exfoliating milk took home a NewBeauty Award in 2026 for “Best Exfoliating Treatment for KP.” It boasts a multi-acid approach: 10 percent glycolic acid and 2 percent salicylic acid team up to exfoliate away dead skin, while 5 percent urea keeps things moisturized rather than stripped. Upcycled pear enzymes and flower acids add another gentle layer of exfoliation to help even out skin tone, and allantoin rounds things out with a calming, soothing finish.

“I recommend the Glytone KP Kit to my patients since it comes with a glycolic acid body wash and exfoliating lotion that’s great for improving bumps and rough skin textures,” says Dr. Schlessinger.
At a stronger 17.5 percent concentration, this kit isn’t quite as heavy-duty as a peel you’d get in a dermatologist’s office, but it’s still a serious formula. It’s best suited for the body—such as the back of the arms or thighs—rather than the face, and should be avoided right after shaving or hair removal to prevent irritation.
3 / 7
This 10 percent lactic acid lotion earned a spot on Dr. Kung’s list for its added soothing ingredients. “The lactic acid and urea help smooth out the skin texture,” she explains. “Feverfew extract and licorice extract also help reduce redness and inflammation; ceramides and oat help the skin retain moisture.”
4 / 7
Recommended by Dr. Blyumin-Karasik, this CeraVe cream doubles as a daily exfoliator, delivering hours of hydration after application and helping calm KP flares over time. Formulated with salicylic acid and three ceramides, it’s fragrance-free and gentle enough for the face, but strong enough for the body, too.
5 / 7
Studies cited by AmLactin suggest lactic acid concentrations above 10 percent are needed to see real results on body KP, which is why Dr. Kung reaches for this stronger, 15 percent formula when patients need something more intensive. “The lactic acid along with moisturizing ingredients help smooth out skin texture while locking in moisture,” she explains.
Too intense for the face, it’s better suited to targeted areas like the arms or thighs. The non-greasy formula absorbs quickly. (Just don’t skip SPF!)
6 / 7
Formulated by Dr. Schlessinger himself, this set targets KP specifically on the face, an area his Glytone recommendation above steers clear of. “While this won’t ‘cure’ this condition, it does improve it significantly,” he says. Low concentrations of salicylic and glycolic acid decongest pores and clear the buildup at KP’s root, while the accompanying gel brings in urea for moisture and vitamin C to fade any lingering discoloration.
