Thanks for the suggestions!
The Mederma seemed to work well for a while, but over the last 2 months I really haven't seen any change.
(So who knows if it was actually working or if it was just the natural healing process.) Been doing deep tissue massage too which has helped tremendously with the healing as far as it being "even" (as opposed to healing raised or indented). We're really trying to avoid corrective surgery or scar reduction treatments...
