How To Get Rid Of Arm Acne

Real talk: I've had bumpy arms for as long as I can remember. Despite having tried every treatment under the sun — really, I even tried the sun — my red, patchy keratosis pilaris (or "chicken skin," as my grandmother so sweetly calls it) plagued my younger years. I wore cardigans to school year-round, I methodically coated the backs of my arms in Sally Hansen's Airbrush Legs spray, and I spent a decade wondering why every boy I dated insisted on swaddling me in blankets, until I realized they mistook my KP for perpetual goosebumps.

"Keratosis pilaris is a build-up of keratin — a hair protein — in the pores that clogs up and blocks the opening of growing hair follicles," dermatologist Doris Day tells Allure. "As a result, small bumps form over where the hair should be."

Even now, I'm still dreading the summer months when I'll be forced to bare my arms and abandon the comfort of sleeves. So instead of spending another season hating on my skin for having KP, I decided to go to the pros to find out exactly how to eradicate keratosis pilaris once and for all.

1. Understand that you can't "cure" keratosis pilaris.

"You can't eradicate keratosis pilaris," says Day. (Editorial note: Bummer.) "It's a genetic condition where, for some reason, the follicles on the outer arms and thighs get clogged and don't naturally exfoliate," she explains. But that doesn't mean you should run out and buy a loofah. "We used to think if you exfoliated enough, you'd be able to undo KP," says Day. "But exfoliating can actually irritate the bumps and make them much worse."

2. Start with chemical exfoliators.

"There isn't a permanent fix, but you can make the bumps go away for a while with glycolic and lactic acid treatments, which will diminish buildup and make your skin feel softer," says Kenneth Beer, a Palm Beach dermatologist. We like Skinfix's Renewing Body Scrub & Cream combo, as well as Dermadoctor's KP Duty Body Scrub with Chemical + Physical Exfoliation.

3. Incorporate a cleansing brush into your routine.

Try swapping your body scrub for a Clarisonic facial brush and a salicylic acid cleanser, like Neutrogena Pink Grapefruit Body Wash, which has 2 percent salicylic acid to penetrate follicles and chamomile to soothe skin.

4. Load up on lotion.

Post-shower, Day recommends applying AmLactin body lotion, with 12 percent lactic acid. "Lactic acid is great for KP because it loosens cells over time to gently exfoliate skin," she says. "It's also a humectant, which means it will add moisture and minimize irritation." Make sure to slather it on every day and you should notice smoother skin within a week or two, she notes.

Another excellent option is SkinMedica's AHA-BHA Cream, featuring lactic acid, malic acid, and glycolic acid, as well as vitamin C, aloe vera, and soothing squalane oil.

5. Visit your dermatologist.

If at-home treatments still aren't cutting it, make an appointment with your physician. "Your dermatologist can greatly reduce the appearance of keratosis pilaris with just a few in-office laser treatments, which help to exfoliate the deepest layers of your skin," says Day.
