Phototherapy for Psoriasis.
Phototherapy is the controlled use of ultraviolet light (UV rays) from natural or artificial sources to treat skin diseases, particularly psoriasis.
Different wavelengths of light produce different effects on the skin. For the treatment of psoriasis, both ultraviolet A (UVA) and ultraviolet B (UVB) are used. UVB phototherapy can be used alone or in combination with other treatments. UVA must be used with other medications to sensitize the skin, usually psoralen. The combined use of a psoralen and UVA is called “PUVA” (psoralen UVA).
Exposure to UVA and UVB light appears to alter the immune response in the skin and slow the growth of skin cells. This leads to a reduction in the build-up of skin plaques that create the psoriasis lesions.
Phototherapy can be time-consuming and inconvenient, but it’s an effective treatment for certain types of psoriasis and a useful alternative to other medications.

Phototherapy for Eczema
Phototherapy, also called light therapy, can reduce the inflammation that is a part of eczema. It can both lessen the itch and help boost the body’s bacteria-fighting abilities. It can be used in specific areas that aren’t responding to other treatments, or over the entire body if needed.
Phototherapy is an in-office procedure conducted by either an allergist or dermatologist. It involves exposing the skin that is affected by eczema to ultraviolet (UV) light.
Phototherapy is considered a second-line treatment and is used only for patients who haven’t had success with other measures. A special light machine is used to deliver targeted bands of UV light just where it’s needed.
Nearly 70 percent of patients who are treated with phototherapy have positive results, but it’s important to note that this treatment is not for everybody.
