Besides, if you get hurt on your skin, you should take it seriously and cope with it carefully.Second, hands and feet are exposed to environment. Some people like to have a sunbath on beach, and their hands and feet will be exposed to ultraviolet ray for long time. After exposure, many people’s skin will become dark. But long-term exposure may induce vitiligo.Third, human hands and feet are at the extreme of blood circulation, and far away from heart. And it is mainly blood capillary, so the blood circulation is very slow. This is also one reason why some people feel hands and feet are very cold in winter.

But different person have different body condition, which means some times it maybe easily to treat. Patient need to have more patience during the treatment and have a positive attitude,it will help the treatment effect.
