Some of the most common causes of white spots are vitiligo, tinea versicolor, hypopigmentation, idiopathic guttate hypomelanosis, and even malnutrition.
Vitiligo occurs when cells in the body stop producing melanin. Though no one knows why this happens this incurable condition affects millions of Americans. Hypogimentation is also the result of a loss of melanin production by melanocytes, or the cells responsible for pigment production.
Tinea versicolor is a treatable and common skin condition that is usually caused by an overgrowth of yeast. The use of antifungal medications and shampoos help to clear up the appearance of white spots. Idiopathic guttate hypomelanosis occurs mostly in fair skinned woman, as the result of aging or heredity. The white spots caused by idiopathic guttate hypomelanosis are usually found on areas of the body that receive the most exposure to the sun.
For some people, white spots can occur as a result of malnutrition, or calcium and vitamin deficiencies. Adding these nutrients back into the diet will eliminate the appearance of these white spots.
