Vitiligo & Psoriasis


Vitiligo is a continual and long term skin problem that produces white depigmentation patches that develop and enlarge only in certain sections of the skin.

Surprisingly, the causes of vitiligo are yet to be precisely established, but most of the research so far points to the following:

  • An autoimmune disorder – the patient’s immune system becomes overactive, and destroys the melanocytes
  • Harm to the skin due to a critical sunburn or cut exposure to certain chemicals
  • Genetic oxidative stress imbalance
  • A stressful event
  • A neural cause
  • A viral cause

To easier explain this condition, scientists have separated vitiligo into two types which are called: non segmental, and segmental vitiligo. Non-segmental vitiligo is the most common type of vitiligo and occurs in up to 90% of the people who have this disorder.The excimer laser and intense pulsed UVB light have been shown to be effective in treating vitiligo and hypopigmentation.

308nm Excimer UV-light is the golden treatment standard for vitiligo

  • To induce T cells apoptosis
  • To stumilaye the melanin cell hyperplasia
  • To promote the pigment secretion
  • To destory the sulfhydryl radical of skin
  • To strengthen the activity of tyrosinase
  • The final result: melanin increase
