How much skin tightening can you expect with Vaser Lipo and Renuvion?

I really want to firm up the upper area of my tummy. I'm just wondering how much skin tightening you can expect to achieve with Vaser lipo and Renuvion combined? I've had a mini tummy tuck last year but am still so unhappy with my upper tummy area. I realise a full TT is what addresses the upper tummy but I really want to avoid this if at all possible. Am I likely to receive a somewhat good result or is it just a full TT that will give me this flat firmer tummy? Thanks so much in advance.
