Symptoms

Keratosis pilaris can occur at any age, but it's more common in young children. Signs and symptoms include:

• Painless tiny bumps, typically on the upper arms, thighs, cheeks or buttocks
• Dry, rough skin in the areas with bumps
• Worsening when seasonal changes cause low humidity and dry skin
• Sandpaper-like bumps resembling goose flesh

When to see a doctor

Treatment for keratosis pilaris usually isn't necessary. But if you're concerned about your or your child's skin, consult your family doctor or a specialist in skin conditions (dermatologist).
