HI welcome to healthcare magic .
you are suffering from vitiligo
there are various treatment options available as it is an autoimmune disease
and to get a complete and permanent cure may be difficult.
In my patients i recommend use of topical steroid
like clobevate '
then a course of oral steroid is given for 4 or 6 wks
other treatment options are use of psoralens like 8MOP on lesions and then giving phototherapy
NBUVB.that is a slow process may take few months with thrice weakly sessions of phototherapy'
another treatment option is use of tacrolimus locally.
treatment response varies from patient to patient.
I also use phototherapy with needling of the lesions.
you can discuss your treatment options with your doctor.
