The actual fact is that this is not vitiligo, but a kind of senile degeneration, medically known as idiopathic punctate white spots, or senile white spots. This kind of white spot has clear boundaries, generally round, slightly depressed, the number of a few to dozens varies, with time will slowly increase. There is no significant difference between men and women, and they mostly occur on the extremities, thighs or trunk, but rarely on the face. The size is usually the size of a soybean slice, no enlargement, and no special treatment.
