What can I do to improve my body contour after Renuvion?

It really depends on where you started out and what your results are now. It's possible that there isn't much more that can be done, but without photos it's impossible to say. I would consider uploading photos or doing a consult with another body contouring expert.

You did not post photos nor state what is your concern, so I cannot recommend anything specifically. I would suggest going back to your surgeon and discussing your concerns and options.

There are a few key factors that would help answer this question better-
-With your initial procedure, did you have VASER assisted lipo? High definition lipo? Traditional Lipo?-What areas are of concern?-Do you have any element of a diastasis recti, or midline muscle weakness, from your prior pregnancies?-Is there an issue of skin redundancy (excess) or skin laxity (looseness)?
Renuvion J Plasma does an amazing job when it comes to tightening areas with skin laxity. In my practice, I incorporate it after VASER assisted liposculpting to address areas of skin laxity (not redundancy). I let my patients know that they can expect about 50% skin tightening, depending on the area, and that it won't address skin redundancy nor diastasis recti.
When it comes to skin redundancy- I recommend skin excision. For a diastasis recti of the abdominal muscles, I recommend an abdominoplasty (tummy tuck).
In certain instances, after J Plasma, you can perform Morpheus8 externally to further tighten the skin. In others, you may be a candidate for a revision surgery.
I'd be happy to go over the details further with a virtual consultation and examination. I also have educational videos on my website that review these topics.

First-hand experience using Renuvion for over a year I never saw a single case of skin tightening by either objective or subjective measures. I literally made measurements between skin markings or moles and there was zero can skin contracture or shrinkage.
After a year I recognize I had been scammed by the sales people and wasn’t going to do that to patients I care about.
I have since sold a device which does not deliver any significant skin tightening that it’s even noticeable.Individuals with significant and abdominal skin laxity need a full tummy tuck.
You didn’t include pictures so we can’t make an assessment but the device you’re referring to doesn’t deliver.
I’m glad I was able to sell mine though I still lost a lot of money having bought into this device which doesn’t do anything other than increase pain during and after the procedure.
