UV light treatment can treat patients living with psoriasis, vitiligo, eczema, certain types of lymphoma and a variety of other skin diseases. It can also reduce skin inflammation and heal damaged skin.
A particular band of non-visible light spectrum, UV light can be used alone or in combination with other medications that are either applied directly to the skin or ingested.
UV light treatment can employ one of two bands of the ultraviolet spectrum: Ultraviolet A (UVA) and Ultraviolet B (UVB). As with most skin issues, the amount of treatment usually corresponds with the severity of the condition. Patients receive full body treatments in specialized light boxes, and smaller areas of the skin are sometimes treated with hand-held devices.
