Keratosis Pilaris in Kids: What Parents Should Know

Keratosis pilaris in kids often shows up on the upper arms, thighs and cheeks, and it can be alarming the first time you notice it. The good news: it is harmless, not contagious and not caused by anything you did.

The better news is that most kids need very little treatment. Here is how to keep things gentle and when to check in with a doctor.

Is keratosis pilaris common in children?

Yes. KP often begins in early childhood and tends to be most noticeable in the school years and teens. It is very common overall, and many kids have a parent with it too.

It shows up as small, rough, skin-colored or reddish bumps. On little ones it often appears on the cheeks, which parents sometimes confuse with eczema or teething rash. It often appears alongside dry skin or eczema.

What causes keratosis pilaris in kids?

Keratin builds up and plugs hair follicles. Genetics is the main driver, and children with dry skin, eczema or allergies are more likely to have it. Dry winter air and long hot baths can make it look worse.

It is not a sign of poor hygiene, a food allergy or an infection. To understand the cause in more detail, see what causes keratosis pilaris.

How do you care for keratosis pilaris in kids at home?

The goal is soft, comfortable skin, not perfect skin. Many pediatricians suggest starting with these basics.

1. Keep baths lukewarm and short. Aim for 5 to 10 minutes.
2. Use a mild, fragrance-free cleanser. Avoid bubble baths and harsh soaps.
3. Pat dry and moisturize within a few minutes. Use a thick, fragrance-free cream or ointment daily.
4. Skip scrubbing. Loofahs and rough washcloths irritate skin.
5. Do not let them pick. Picking causes marks and can lead to infection.
6. Add a humidifier in dry months. It helps with winter flares.

Kids also feel self-conscious as they get older, so keep it low-key. Treat KP as something that is normal, not a problem they need to fix.

Which ingredients are okay for kids and which need a doctor?

The pattern is clear: moisturizer first, and anything stronger goes through your child's doctor. Never use adult exfoliating or retinoid products on a child because the label says it is gentle.

How do you talk to your child about KP?

Keep it matter-of-fact. Tell them it is a common skin quirk, that lots of people have it and that it does not hurt. Kids pick up on your worry, so a calm tone goes a long way.

Teach them not to pick, and make moisturizing a normal routine like brushing teeth rather than a fix for something wrong. Older kids and teens who are bothered should be part of the decision about what to try.

Do any foods or allergies cause KP in children?

There is no good evidence that food causes KP, and cutting foods out of a child's diet to treat it is not recommended without a doctor. KP is more common in children with eczema and allergic conditions, but that is an association, not a cause. If you are curious, read keratosis pilaris and diet.

What about sun and swimming for kids with KP?

Sun is generally fine and mild sun often makes KP less noticeable in summer. But chlorine and long soaks can dry skin, so rinse after the pool and moisturize right away. Use sunscreen on exposed areas as you would for any child.

When should you see a pediatrician about KP?

• The bumps are painful, pus-filled, crusted or spreading quickly.
• Skin is very itchy or has dry, scaly patches, which may be eczema. See keratosis pilaris vs eczema.
• Bumps look like a different problem, such as a rash with fever.
• Your child is unhappy about the way it looks and you want treatment options that are safe at their age.

Redness, swelling or warmth around bumps can be a sign of infection, so get those checked. Keratosis pilaris vs folliculitis shows what infected follicles look like.

Will keratosis pilaris go away as my child grows up?

Often it improves, especially after the teen years, and some people find it nearly gone by their 30s. It can also hang on for life. There is no way to predict which, so treat what bothers your child today. Our guide on does keratosis pilaris go away covers the typical timeline.

Because KP is chronic, even good treatment tends to wear off if you stop. Keep expectations modest and keep routines simple so they will actually stick.

What happens when kids with KP become adults?

If KP continues into adulthood and gets in the way of enjoying summer clothes, adults have more options. A urea and lactic acid moisturizer is a good first step, and persistent cases can be discussed with a doctor. You can read more in how to get rid of keratosis pilaris.
