To address all of your skin laxity (and your likely umbilical hernia) you would need a tummy tuck. While J plasma is a great tool, you have too much skin laxity for it to be very effective.

Hello It may be more about skin looseness rather than fat. The fat thickness can be determined with ultrasound. If it's fat, it can be removed with Vaser Lipo. If not, a skin tightening procedure like Renuvion J Plasma can be done.

Hello The most effective solutions for fibrosis that occurs after liposuction are massage, fat injection, and PLA injection. If a steroid injection is to be done, it should be done with great caution.

Fat dissolving injections will probably make things worse, not better. The only hope you have for improvement is by going to an experienced surgeon to do more liposuction, probably using a Vaser device with it. Even then I don't know how much improvement you can reasonably expect to see.

You could get liposculpture before having children, as it wouldn’t interfere with your ability to have kids. There’s no need to wait until after pregnancy. The recovery time is approximately 7–10 days.

Kybella is a fat dissolving injeciton that works quite well in this area. It can also be combined with some laser tightening for even better results.
