It sounds like your problem could be addressed by some form of liposuction with a possible surgical scar revision.
Once you have a scar made by an incision, it can never be made to disappear. It can be made to be appear less prominent by evening out the disparity in the fat levels of the upper and lower areas. And, if the scar is indented or widened, removing it and restitching the area can result in a less prominent incision line.
How the liposuction is carried out is a matter of the surgeons preference. There are a number of techniques available, but the bottom line is getting rid of the excess fat. Non invasive methods are not likely to solve this problem.
