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
