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.

When is phototherapy used?

Phototherapy is commonly used to control widespread dermatitis (eczema) and psoriasis. It may be used to treat vitiligo, but response may be slower and recovery only partial.

Phototherapy may also be used in less common conditions where it has been reported to be useful.
