Vitiligo or Leucoderma is skin condition leading to the development of white patches on the skin because of the loss of melanocytes. Melanocytes are cells which are responsible for producing the skin pigment known as melanin which gives colour to the skin and it also protects from the ultraviolet rays. Usually, the colour of hair and skin is formed by melanin. When the cells that produce melanin stop producing melanin, it results in the appearance of white spots and patches. The vitiligo is neither contagious nor life-threatening. It can be stressful, can have a psychosocial impact and cosmetic concerns. Vitiligo can affect the large areas (generalized), limited areas (localized), fingertips and lips (lip-tip vitiligo) or the mucosal surfaces such as the lips or the genitalia (mucosal vitiligo). Vitiligo can occur on any part of the body, including face, trunk, elbows, knees, hands, and feet. Vitiligo can be classified as:
  1. Non-segmental Vitiligo – The non-segmental or generalized vitiligo is the most common type of vitiligo which affects both sides of the body. Patches can be seen all over the body.
  2. Segmental Vitiligo – White patches are present only on one half of the body, and it is mostly seen in children.
