Loss of color in the tissues inside the mouth and nose
Change in color of the retina (inner layer of the eyeball)
Types of Vitiligo
It can be classified into several types based on the pattern and extent of depigmentation
Generalized
- This is the most common type.

Segmental
- Depigmented patches appear on one side or part of the body.
