Vitiligo is a skin condition that causes patches of skin to lose their color. This happens when the cells that produce pigment stop working or die. These patches can appear anywhere on the body, including the face, hands, and arms, and can also affect hair and the inside of the mouth. The exact cause of vitiligo is not known, but it is believed to be an autoimmune disorder where the body's immune system mistakenly attacks the pigment-producing cells. Vitiligo is not painful or contagious, but it can affect a person's appearance and self-esteem. Treatment options include creams, light therapy, and cosmetic solutions to help even out skin tone, though results can vary.
