Phototherapy (Light Treatments)

Phototherapy is the dermatology-directed use of ultraviolet light to medically treat skin disease. Narrow band ultraviolet B light treatments are very effective in the treatment of skin disorders such as psoriasis, vitiligo, eczema, itching and some lymphomas of the skin. Not all dermatologists provide these treatments. Specialized PUVA treatments, another type of phototherapy, are performed for skin disease on the hands and feet. > More info
