What is keratosis pilaris? Derms explain, and recommend how to treat it | CNN Underscored

Whether you’re dealing with rough patches, flaking or more severe conditions like eczema, dry skin can be a really uncomfortable and even painful skin issue to deal with. And with hot summer days in full swing, you may be realizing that your everyday skin care routine just isn’t cutting it anymore.

If you’re noticing any areas of small, rough bumps on your body that definitely aren’t zits, you may be dealing with keratosis pilaris. Ahead, we’ve asked dermatologists to break down exactly what it is, what causes it and what you can do to treat it.

Keratosis pilaris is a common skin condition “characterized by tiny, rough bumps on the surface of the skin,” explains Dr. Anar Mikailov, a Harvard-trained board-certified dermatologist and the founder of KP Away. Often referred to as “chicken skin” or “strawberry skin,” these bumps typically appear on the upper arms, upper thighs, cheeks and buttocks.

Fortunately, keratosis pilaris is typically harmless, explains Dr. Dendy Engelman, a board-certified dermatologist based in New York City. “The bumps normally don’t itch or cause any pain,” she explains, “the concern is mainly just cosmetic.”

However, there can be more severe cases, explains Mikailov. The area can become “irritating, itchy and persistent” and may start to feel dry or sandpaper-like. Many people will discover the condition when they can’t scrub away the itchy, occasionally painful bumps. In this case, Mikailov recommends seeing a dermatologist for a formal diagnosis and a sustainable management plan.

Keratosis pilaris occurs when hair follicles are blocked or clogged, which causes bumps on the skin. However, there are varying opinions on what causes the blockage.


Engleman explains that keratosis pilaris is caused by “a buildup of retained keratin, which is a protein found in your skin, nails and hair.” Mikailov, on the other hand, describes our sebaceous glands and their secretion of sebum — our body’s natural oil that ensures healthy skin, hair and nails — as the key factor. “When sebaceous glands are missing or not functional, it leads to a lack of naturally produced oil, fats and acids that normally promote healthy hair follicle growth and skin turnover,” he explains. “Ultimately follicles become ‘plugged’ and the bumps of keratosis pilaris follow.”

No matter how the blockage is caused, it produces “evenly spaced out, pink, firm bumps,” explains Dr. Rachel Maiman, a board-certified dermatologist at Marmur Medical. There’s likely a “heritable component given its propensity to run in families,” she adds. Dr. Ellen Marmur, a board-certified dermatologist and the founder of MMSkincare, echoes this idea, emphasizing keratosis pilaris as “a genetic skin problem inherited by one parent and a special form of eczema.”

For many people, keratosis pilaris gets worse during the winter when the weather is drier. It can also come about with different environmental changes, like hard water or products that irritate your skin, particularly those with strong exfoliating acids or fragrances, Mikailov shares.

Another factor to consider is your age and stage of life. “Certain periods of life including puberty, pregnancy and menopause” can contribute to keratosis pilaris, Mikailov explains. It’s also very common to see during teenage years, he says, sharing that it affects at least 50% of all adolescents. “For some people keratosis pilaris improves with age, but for most people it persists and requires a smart, gentle and safe skin care routine.”

“While there isn’t a single cure for keratosis pilaris,” explains Engelman, “there are products that can help relieve some of the symptoms and prevent it from forming.” She recommends AHA- and BHA-based body products, which, when paired with hydrating and soothing ingredients, “help to remove dead skin cell buildup without compromising the skin barrier.”

Maiman recommends products that include keratolytic agents, which as she explains, “work to break down the clumps of dead skin cells” blocking your hair follicles. Some common keratolytic agents include salicylic acid, urea, ammonium lactate and glycolic acid.

All in all, the key to managing keratosis pilaris in the long term is to “maintain a healthy skin care routine that includes cleansing, deep exfoliation and moisturization,” Engelman explains.

Engelman explains that the pumice buffing beads serve as a physical exfoliant that “targets the symptoms of keratosis pilaris by gently scrubbing away dead skin cells and helping to unclog blocked hair follicles.” At the same time, “the mixture of both glycolic and lactic acids chemically exfoliate the skin” while vitamin E conditions and smooths it, explains Maiman,
