Tonks, the RX cream will greatly reduce the scarring. You will however, like Leslie said, have to take extra care after healing by using sunscreen on it. The RX cream has actual silver in it, so if she gets some of it on something white it will turn it gray/black. Don't worry, it will wash out, just use a little laundry pretreater. My Dad's face and hands got burned pretty bad quite a few years ago and the Doc gave him the same cream. He had absolutely NO scarring that we could find after it all healed.
