I am a vitiligo patient for years,i accepted the treatment of  Derma 308 Targeted 

phototherapy in the hospital for about 8 weeks ,and because it was  really not  

convenient for us to go to the hospital every week ,and it's really cost too much 

,then I bought the UVB phototherapy using at home now .After the two month 

treatment,melanin has already grown on the patches ,but there is still has the patch 

,how long will be cured?
