Keratosis pilaris, sometimes called “chicken skin,” is a common skin condition that causes patches of rough-feeling bumps to appear on the skin. Also known as follicular keratosis, this is a hereditary skin disorder that causes goosebump-like lesions on the back of the arms, thighs or buttocks. The patches of bumps tend to get dry and itchy, particularly during the winter months. Keratosis pilaris occurs at any age. Because it is hereditary, there is no method of prevention. In some cases, it goes away on its own over time; in other cases, the condition is chronic.
Keratosis pilaris is caused by a build-up of keratin, a protein in the skin that protects it from infection. Keratin plugs up hair follicles causing the rough, bumpy rash.
If the itch, dryness, or the appearance of your skin bothers you, treatment can help. A dermatologist can create a treatment plan that addresses your concerns.
