White patches on the skin, premature graying of the scalp, eyelashes, eyebrows, and beard, and sometimes a loss of color inside the mouth—these are some of the distinct signs of vitiligo. Some people might mistake it as a disease brought about by too much sun exposure

Vitiligo is a medical condition in which irregular, white patches appear on the skin because of loss of melanin, the pigment that determines the color of skin, hair and eyes. While the exact cause is not known, heredity and a disturbed immune system are believed to be important contributing factors to this condition, which is also known as leucoderma.

Vitiligo is a skin disease characterized by white patches of various shapes and sizes. It is caused by the failure of certain areas of the skin to produce melanin, a pigment responsible for natural skin color.
“An estimated 1 to 2 million Americans have vitiligo. It affects both sexes and all races, but is often more noticeable and more disfiguring in people with darker skin. Vitiligo usually starts as small areas of pigment loss that spread and become larger with time. These changes in your skin can result in stress and worries about your appearance,” said the Mayo Clinic.
