Hello,
Well vitiligo is usually begining with a few small white patches which afterwards spread over the body. This period of time is usually several months. Sometimes these patches continue to widen and spread, but usually they stay in the same place for years and I hope that this is going to be the case with your little girl. The location of these macules shifts and changes over time because certain areas of skin lose and regain their pigments so it is quite possible that your daughter is going to have her normal face color after some time.
Unfortunately there is no cure for vitiligo but certain treatments tend to help. You should discuss this with your doctor.
