If your child has tiny bumps on their arms, legs, or cheeks that feel rough like sandpaper, they may have keratosis pilaris (KP).
This common skin condition is sometimes called “chicken skin,” because the bumpy patches can look like (you guessed it) chicken skin.
What does KP look like?
These small, rough bumps can look like goosebumps or mild acne. They may be skin-colored, white, or red and inflamed, especially in children with sensitive skin.
They’re most often seen on:
- Upper arms
- Thighs
- Cheeks
- Buttocks
What Causes KP?
“KP happens when keratin, a protein in the skin, builds up and plugs hair follicles,” explains Howard Pride, MD, a pediatric dermatologist at Carilion Clinic. There’s no single cause, but it tends to run in families. If you or other relatives have KP, your child is more likely to as well.
It’s also more common in children who have:
- Dry skin
- Eczema
- Asthma
- Allergies
Cold, dry weather can make KP more noticeable, which is why it often seems worse in the winter. It’s not contagious.
Does it hurt or itch?
Most of the time, no. Some children may experience mild itching or irritation, especially if their skin is very dry.
How can you get rid of KP?
There’s no permanent cure, but there are ways to improve how the skin looks and feels.
1. Over-the-counter products
Use a hydrating cream or lotion made for “rough” or “bumpy” skin once per day. Dr. Pride recommends looking for gentle, child-safe products with ingredients like:
- Urea
- Lactic acid
- Salicylic acid
- Glycolic acid
These help soften and smooth the skin over time. Because these products can burn or sting when applied, it’s best to avoid them with very young children and use a bland, thick moisturizer instead. Avoid scrubs or other harsh exfoliating products, which can irritate skin and make KP worse.
2. Don’t pick
It’s tempting to pick at or pop the bumps, but this can lead to scars and discoloration.
3. Keep baths lukewarm
Hot water dries out your skin. After bathing, pat the skin dry and apply moisturizer right away.
4. Be patient
Improvement takes time. Stay consistent and continue to treat KP even after the skin has cleared to keep it from coming back.
“It’s important to note that KP isn’t harmful and you don’t have to treat it. If it’s not bothering your child, it’s completely fine to leave it alone,” says Dr. Pride.
Will it go away?
For many children, KP improves as they get older. Some people continue to have it into adulthood, but it often becomes less noticeable over time.
When should you see a doctor?
KP is harmless, but you may want to check in with your child’s doctor if:
- The bumps become very red, swollen, or painful
- The skin is cracking or bleeding
- You’re unsure if it’s KP or another skin condition
If you have questions or concerns about your child’s skin, reach out to your pediatrician.
