what is uv phototherapy?
Type:Uv phototherapy Time:2016-11-28 13:57:33UV Phototherapy is the use of UV light to treat psoriasis, vitiligo, eczema and other skin disorders. In treatments, the skin is exposed to a special type of light which comes from a medical device commonly referred to as a phototherapy unit. These units range from hand-held and table-top devices for spot treatment of small areas to cabinet or ¡°walk-in¡± units for patients requiring full body treatment. The medical lamps in these phototherapy units emit ultraviolet (UV) light in a wavelength that creates changes within the skin cells. The cells in most patients then begin to behave normally, which reduce or eliminate the symptoms of the skin disease.
