Abstract A method and composition of treating psoriatic skin in which capsaicin is applied topically to the psoriatic skin in a pharmaceutically acceptable carrier wherein capsaicin is present in therapeutically acceptable concentrations of between about 0.01 and about 1 percent by weight. Subsequent exposure of the treated psoriatic skin to ultraviolet light in small doses aids treatment.
