Hi sir / mam my son was 14 years old he was suffering from vitiligo from back 2 months this white patches came from inner nose and now it came closer to lips. By doctors suggestion he was using melanocyl ointment after using few days he told that it was burning, and itching and it became reddish in colour. After using this ointment for one month we observed that it was lightly increasing its place and we not found any result please suggest me anything.
