My doctor told me that he needed to be aggressive and remove this particular spot that had a decent amount of scar tissue in order for the prior smaller scars to heal correctly. he said it was deep and it would need to heal over a 3 month period and would use a filler to raise the scar. I am at a complete loss as to what can be done now as the co2 treatment caused this scar. As of right now I have been instructed to wash 3 times a day and keep the scar covered with aquaphor. Please help!!!
