Urea is used to treat dry/rough skin conditions (such as eczema, psoriasis, corns, callus) and some nail problems (such as ingrown nails). It may also be used to help remove dead tissue in some wounds to help wound healing. Urea is known as a keratolytic. It increases moisture in the skin by softening/dissolving the horny substance (keratin) holding the top layer of skin cells together. This effect helps the dead skin cells fall off and helps the skin keep more water in.
