Hi My daughter has a vitiligo and 6 white patches are some are decreasing in size but some new are occures. And treatment is also started from dermologist but why new are occures???

A. Well it is a problem that increases over the time in most of the cases which is why pro new patches are also appearing further you will have to check with your dermatologist for a proper reason as they will be able to give you a satisfactory response after checking how much it is increasing what is the pace of it
