Signs and Symptoms
The most common locations for keratosis pilaris include:
  • Backs of the upper arms
  • Fronts of the thighs
  • Buttocks
  • Cheeks, especially in children
Tiny (1–2 mm) white to gray bumps occur, centered in the hair follicle. Sometimes a thin, red ring may surround the white bump, indicating inflammation. The bumps all look very similar to one another, and they are evenly spaced on the skin surface.

Rarely, people with keratosis pilaris may complain of mild itching.

Keratosis pilaris tends to improve in warmer, more humid weather, and it may worsen in colder, drier weather.
