Overview

Keratosis pilaris is a very common and harmless skin condition characterized by small bumps. These bumps usually appear on the arms, thighs, or bottom, but can occur elsewhere. The skin may also feel itchy, and symptoms often improve in summer and worsen in winter. It affects people of all ages and is not contagious. This condition occurs when hair follicles become blocked by a buildup of keratin, a natural substance in skin, hair, and nails. The exact reason for this keratin buildup is unknown, but it tends to run in families. Therefore, if your parents have it, you may also develop it. While there is no cure, symptoms can be managed with self-care like moisturizing, using mild soaps, and gentle exfoliation. Pharmacists can recommend suitable creams, and in some cases, a doctor might suggest other treatments, though these are not always proven effective or available on public healthcare systems.
