Chicken skin is the common name for periorbital keratosis, the cause of which is unknown and may be related to genetic factors. There is no significant correlation with vitamin deficiency, and the clinical manifestations of the disease are similar to those of vitamin A deficiency. Vitamin A deficiency skin manifests as keratotic papules on the extremities, buttocks and both sides of the back, along with dry skin, night blindness and damage to other internal organs. Although chicken skin is not caused by a vitamin deficiency, vitamin A supplementation is effective in some patients. Since vitamin A can be toxic when taken orally in excessive amounts over a long period of time, it should be used under medical supervision for patients who need to take it. For most patients with chicken skin, topical treatment is preferred. Mild cases can be treated with topical emollient lotion or urea ointment, while more pronounced cases can be treated with topical vitamin A cream or chemical peels.
