Medicine for Daniels scars (7yo)

On August 8th, we had to go through the most horrific thing for us to go through, our baby boy who is only 7 years old, got bit severely by a pitbull.  It tore his whole left cheek down, and with the help and best surgeons he could get from Brenners Childrens hospital, they helped put his face back together like a puzzle, with no nerve damaging, just going to be very bad scarring.  He starts school in 2 weeks and we want to get everything we can to heal him. The medicine is to restore his face.  The insurance we have does not cover cosmetic medicines for scarring. We know how kids can be cruel and just want to do the best medicines we can. We are so blessed to have had the surgeons we did, and great nurses. They couldnt believe his bravery, he had so much peace going through this situation, Gods hand was with the surgeon and with Daniel the whole time. We are thankful for all the prayers, we truly appreciate it. Just want him to heal and be comfortable as possible during this healing process. We dont want him to feel less confident in himself with how kids are now a days, so we are going to try multiple solutions to his scarring and anything left over will go to what was not paid for by insurance. Anything to help our little boy will be forever grateful.
Thank you so much.
