hello....my daughter is 3 years n 2 months...she has one small white patch on her face since last month what could it be ...does any of your kids have the same? and what are the causes

A. In such a case it is difficult to comment here because proper assessment isbre required which is possible only with clinical interaction so it will be better to visit your doctor /pediatrician for proper guidance regarding this. The treating doctor will advise you the proper investigation if required as well as prescribe appropriate treatment as per the requirement.
