Keratosis pilaris is a common skin condition characterized by small, rough bumps on the skin, typically on the upper arms, thighs, buttocks, and sometimes on the face. These bumps often have a sandpaper-like texture and may be white, red, or flesh-colored. Keratosis pilaris occurs when the skin produces too much keratin, a protein that forms the outer layer of the skin. This extra keratin blocks the hair follicles, leading to the formation of bumps. While keratosis pilaris is harmless and usually does not cause any symptoms other than mild itching, it can be bothersome or a concern for how the skin looks. Treatment options include moisturizing creams, exfoliating scrubs, and ointments applied directly to the skin to help soften the bumps and improve the appearance of the skin.
