I had a liposuction a view years ago, the scars above my buttocks and under my buttocks turned out very big and ugly. Even if I have been extremely careful with not stretching my skin during the repair period. I had one revision for the scars under my buttocks and used "silicone plasters", that didn't work so well, the scars still got big. I have a new lipo in 14 days, using the same scars. Is there anything I can do pre-op, during op (injection?) or post operation, to make them appaire nicer?
