If vitiligo spreads on four limbs, feet and hands, it is called acra type vitiligo. Usually, white spots on hands and feet are not of large size, and spread sporadically. Especially on joints, finger tip positions, the vitiligo is very difficult to treat. And it is very easy to spread and reappear. For acra type vitiligo, patients should not ignore the nursing care.

First, we usually use hands and feet frequently, and they are easy to get trauma and are very easy to touch pollution substances. But most people think that just little hurt and a little unclear things will not lead to diseases. However, vitiligo can happen inadvertently. There are the same cases in clinic. Therefore, specialists suggest that patients who work outdoors should pay attention to protection. And they should try to wear gloves to work to make sure your skin are clean. 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 external 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 will induce vitiligo.
Third, human hands and feet are at the extreme of blood circulation, and far away from heart. And it is almost blood capillary, and the blood circulation is very slow. This is also one reason why some people’s hands and feet are very cold in winter. Blood is responsible for transportation, and medication is also sent to lesion positions via blood. If blood circulation is very slow, the medication effect will decrease and lead to bad effect.
