They are more of aesthetic problem particularly if they form on visible areas of the body.

Vitiligo is one of the skin disorders which features with white spots on the skin. In people suffering from vitiligo white spots occur after the body has been exposed to the sun. This is a quite common skin disorder and it affects approximately 2 million people in the United States.

Another skin disorder which features with white spots on the skin is pityriasia alba. It basically affects children and teenagers. The white patches of the skin are generally found on the face, neck, trunk, hands and legs. This is not a contagious disease and can be easily brought under control with certain medications.
