Greetings. I guess it's important that you see a qualified dermatologist and he'll be able to explain the problem of vitiligo to you and then you'll have clarity about your condition and it's treatment. This is important since treatment of vitiligo runs into months. Also prognosis depends on extent and type of vitiligo. You could contact me on follow up messaging for further queries or if you wish to consult me you could book an appointment via my Practo profile. Warm regards.
