Keratosis Pilaris Is a Keratinization of Hair Follicles

Keratosis pilaris, a common and generally harmless skin condition, is characterized by the keratinization of hair follicles, primarily affecting the upper arms and thighs. It typically emerges in early childhood and can intensify during adolescence. The condition is often associated with other disorders such as atopic dermatitis, ichthyosis vulgaris, obesity, diabetes mellitus, and malnutrition, and can also be seen in individuals with Down syndrome and Noonan syndrome. While keratosis pilaris may improve with age, treatments are available to manage its symptoms, including the use of emollients, exfoliants, anti-inflammatory medications, phototherapy, and laser therapy.
