Keratosis Pilaris

Keratosis pilaris is a common condition when numerous rough small bumps appear on the outer skin of the upper arms. They may be skin colored, red, or brown. They may also occur on the thighs and cheeks, and less often on the forearms and back. When more KP appears and both on the cheeks and upper arms, it is a variant known as Keratosis Pilaris Rubra. Although it may be cosmetically unappealing, KP is completely harmless.
