Vitiligo is a condition that causes depigmentation of parts of the skin. It occurs when skin pigment cells die or are unable to function. The cause of vitiligo, aside from cases of contact with certain chemicals, is unknown, but research suggests it may arise from autoimmune, genetic, oxidative stress, neural, or viral causes.
Vitiligo affects people of all skin types, but it may be more noticeable in people with darker skin. The condition is not life-threatening or contagious. It can be stressful or make you feel bad about yourself.
The main sign of vitiligo is loss of skin color or loss of skin pigment that produces light or white patches on your skin. Usually, the discoloration first shows on sun-exposed areas, such as the hands, feet, arms, face and lips.
Vitiligo signs include -
- Skin discoloration
- Premature whitening or graying of the hair on your scalp, eyelashes, eyebrows or beard
- Loss of color in the tissues that line the inside of your mouth and nose
- Loss of or change in color of the inner layer of the eyeball
- Discolored patches around the armpits, navel, genitals and rectum.
