As part of treatment I was supposed to show my white patches to sun light daily. But I am too lazy and would wake up late did not follow the sun exposure daily in the early part of the treatment. Dr pranjal would be scolding me each time for not showing to sun. she was checking my skin through some microscope and so she knew I was not applying medicine and showing to sun. she kept motivating me to be regular. Finally one day I decided to become fully regular with medicine and treatment. And I am seeing good results because of that. So dr can give medicine but patient should also follow correctly.
