A condition that causes rough patches and small, tiny bumps on the skin.

With keratosis pilaris, rough patches and tiny bumps appear on skin. It's harmless and often considered a common variant of skin.

Rough patches and tiny bumps show up on the arms, thighs, cheeks, and buttocks. The bumps usually don't hurt or itch.

Keratosis pilaris usually clears up on its own with time. Self-care habits may improve how the affected skin looks and feels. These include a gentle skin care routine, medicated creams and moisturizers.
