This research study aims to evaluate the effectiveness of an investigational device which is similar in appearance to a "tanning bed" but which emits ultraviolet irradiation of a specific wavelength known as UVA1. This device has not been approved by the Food and Drug Administration (FDA) for general use in this country, as of yet, but it has been used quite successfully in Europe for several years in treating such conditions as scleroderma, atopic dermatitis, urticaria pigmentosa and other skin conditions.
