Keratosis pilaris

Keratosis pilaris is a condition that is usually found on the outer areas of the upper arms, thighs and cheeks. It is characterized by flesh-colored to slightly red, rough, distinct bumps. Keratosis pilaris is occasionally itchy, but otherwise it is only significant cosmetically. It is caused by a plug of dead skin cells that forms around a hair follicle. These "plugs" give the skin a sandpapery or "goose-flesh" feeling. Keratosis pilaris is usually worse during the winter months and is most commonly seen in children and young adults. Often the surrounding skin is dry.

What to expect

Keratosis pilaris is a benign condition, and treatment is only necessary for cosmetic reasons. The treatments do not work in all patients. For most children, treatment is unnecessary.

Treatment

Lubricants may help with the dryness but do not tend to clear the bumps. Mild peeling agents are most effective in opening the plugged hair follicles by removing the excess skin. Each person may respond differently to therapies, but urea preparations (such as Carmol), lactic acid creams (such as Lac Hydrin or Am-Lactin ) and topical retinoids (such as Differin, Retin-A, Avita or Tazorac) are the most commonly used therapies. Effective therapy must be continued on a regular basis or the keratosis pilaris recurs.
