Vitiligo is a skin condition that is characterized by loss in its pigmentation. The condition is attributed to the death of melanocytes, the cells responsible for skin pigmentation. The exact reason behind vitiligo is unknown, but autoimmunity, oxidative stress and genetic, viral or neural causes are suspected as the likely culprits behind the condition.

Less than one percent of world population is known to be affected by vitiligo. Though this rare skin condition does not cause any physical discomfort, the discolored skin patches are often itchy. The part of the skin that becomes pale due to vitiligo gets vulnerable to sunburn when exposed to direct sunlight.

There are two types of vitiligo
• 1. Segmental vitiligo: Occurrence of white skin patches on one part of the body. It is less common form of vitiligo
• 2. Non segmental vitiligo: Occurrence of symmetrical white skin patches all over the body.
