What is phototherapy?
Phototherapy is the use of 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.
The medical lamps in these phototherapy units emit ultraviolet (UV) light in a wavelength that creates changes within the skins cells. The cells in most patients then begin to behave normally, which reduces or eliminates the symptoms of the skin disease.
