Keratosis Pilaris

Keratosis pilaris (KP) is a common skin disorder characterized by small, rough bumps on the skin, usually on the upper arms, legs, and buttocks. It is caused by the overproduction of keratin, the protein that forms the protective outer layer of skin, which plugs the hair follicles and creates the bumps. KP is usually harmless and may improve over time, without treatment. Common treatments include lifestyle changes, moisturizers, gentle exfoliation, and topical medications. Although KP is not painful or harmful, it can be a source of embarrassment and adversely affect quality of life. Therefore, understanding how it can be treated and prevented can be beneficial.
