Keratosis Pilaris (Chicken Skin)

Overview

What Is Keratosis Pilaris?

Keratosis pilaris (care-uh-TOE-siss pill-AIR-iss) is a common skin condition that causes tiny bumps. They’re most often on the upper arms, thighs, buttocks, or cheeks.

Keratosis pilaris isn’t an infection and it's not contagious. Although the condition can vary from person to person, it tends to get better with time.

Top Things to Know

• Keratosis pilaris is a common skin condition that causes small bumps on the skin.
• Kids may have rough, dry bumps that look like goosebumps or “chicken skin.”
• Treatment may include gentle skin care, moisturizers, and avoiding hot showers.
• Keratosis pilaris is not contagious and usually gets better over time.

Signs & Symptoms

What Are the Signs & Symptoms of Keratosis Pilaris?

Keratosis pilaris happens in young kids but is also common around puberty. The condition causes small bumps on skin that may:

• look reddish, white, brown, or black based on your child’s skin tone
• feel dry and rough like sandpaper
• form on the upper arms, thighs, buttocks, or cheeks
• come and go but tend to get worse in winter

Keratosis pilaris can look like goosebumps. The bumps don’t hurt or itch and don’t go away quickly like goosebumps.

Causes

What Causes Keratosis Pilaris?

Keratosis pilaris happens when a protein called keratin plugs the hair follicles (sac-like pits in the skin). The condition is genetic. So, if your child has it, chances are a family member has it too — or had it.

Diagnosis

How Is Keratosis Pilaris Diagnosed?

Your doctor or a dermatologist (a doctor who treats skin problems) can look at your child’s skin and see if it’s keratosis pilaris.

Treatment & Care

How Is Keratosis Pilaris Treated?

Keratosis pilaris usually goes away on its own, and most people don’t do anything to treat it. But if the bumps bother your child, they can try:

• Taking warm showers or baths, not hot ones
• Using a mild, non-soap cleanser when washing their body and face
• Applying a mild moisturizer several times a day. Moisturizers that have lactic acid or salicylic acid can help soften bumps and make skin less rough.

If you’re not sure what products to choose or your child’s skin doesn’t improve, talk with your doctor. Other treatments might be available.
