Keratosis pilaris: Signs and symptoms


What keratosis pilaris looks like

The rough-feeling bumps can appear in many colors, including skin colored and white.

This common skin condition causes tiny bumps that can:

  • Feel rough and dry like sandpaper

  • Resemble the skin of a plucked chicken or goosebumps

  • Become more noticeable in winter or a dry climate

  • Itch

  • Appear in different colors, including the same color as your skin, white, red, pinkish purple (on fair skin), and brownish black (on dark skin)

Some people have a few flesh-colored bumps. Others have noticeable bumps that look like pimples or a rash.

Where keratosis pilaris appears

These bumps can appear anywhere on your skin, except on your palms and soles. Bumps on the arms are common. Most people will see these bumps appear in the following areas:

Children: Upper arms, thighs (front), and cheeks

Teens and adults: Upper arms, thighs (front), and buttocks

Some people develop so many bumps on their skin that the bumps extend to their lower legs and forearms.
