Keratosis Pilaris

Overview :

Keratosis pilaris is a disorder that occurs around the hair follicles of the upper arms, thighs, and sometimes the buttocks. It presents as small, benign bumps or papules that are actually waxy build-ups of keratin. Normally skin sloughs off. However, around the hair follicle where the papules form, the keratinized skin cells slough off at a slower rate, clogging the follicles.

This is generally thought to be genetic disorder, although the symptoms of keratosis pilaris are often seen with ichthyosis and allergic dermatitis. It can also be observed in people of all ages who have either inherited it or have a vitamin A deficiency or have dry skin. Keratosis pilaris is a self-limiting disorder that disappears as the person ages. It can become more severe when conditions are dry such as during the winter months or in dry climates.
