dear hello. sorry to hear that your 4 yrs daughter got vitiligo
. the disease will not respond in 2 weeks. this is very small time . so keep your medication on and do not loose hope. look out for new patches of white colour coming elsewhere on the body and make a chart of the change is size of existing patch. If the patch remains stationary for more than 6 months and no new patch comes, then even if the patch has not changed, melanocyte
transfer and cure for patch can be done by plastic surgery
. so no need to worry and be optimistic. bye.
