Vitiligo & Psoriasis

Phototherapy is the use of ultraviolet (UV) light to slow the rapid growth of new skin cells. This is helpful in treating psoriasis, which causes skin cells to grow too rapidly. There are two types of ultraviolet (UV) light therapy:

  • UVB light is used alone, with tar products (Goeckerman treatment), or with anthralin applied to the skin (Ingram regimen).
  • UVA light used with psoralen drugs is called PUVA. With PUVA, the treatment time is greatly reduced, from 20 minutes to about 2 minutes.


Narrowband UVB light, or Phototherapy, can help create re-pigmentation. It is currently considered the "gold standard" treatment when Vitiligo covers 20% or more of the body. This process is slow, working from the outer edges of each patch inward, so regular Vitiligo light therapy twice a week for a year or more. Phototherapy equipment has been well-studied and has been proven to be an effective treatment for Vitiligo. Phototherapy Vitiligo light treatment is generally well-tolerated in both adults and children.


Psoriasis is characterized by patches of inflamed red skin. Psoriasis develops because the outer layers of skin cells reproduce too fast. Recent studies show that psoriasis may be an immune disorder in which T-cells behave abnormally. Psoriasis causes pain, itching, and limited motion. It also causes stress and impacts quality of daily life.

UV psoriasis light treatment, also known as UV Phototherapy, exposes the T-cells, causing them to die. In this way, the light therapy reduces inflammation, and slows the rate of skin cell production.
