Xeroderma is a skin condition characterized by what?
Xeroderma, xerosis or xerosis cutis is a skin condition characterized by excessively dry skin. In most cases, it can safely be treated with emollients or moisturizers. Xeroderma occurs most commonly on the scalp, lower legs, arms, hands, the knuckles, the sides of the abdomen, and thighs. Symptoms most associated with xeroderma are scaling (the visible peeling of the outer skin layer), itching, and skin cracking. The term is derived from the Greek words for "dry skin".
Repeated application (typically over a few days) of emollients or skin lotions/creams to the affected area will likely result in quick alleviation of xeroderma. In particular, application of highly occlusive barriers to moisture, such as petrolatum, vegetable oils/butters, and mineral oil have been shown to provide excellent results.
However, many skin creams include common allergens such as fragrances, parabens, and lanolin.
