Emscult Neo + Coolwaves - is this a good idea for tummy tightening? (Photo)

I'm a 40 y.o. man with a bit of loose skin on my tummy. I had SmartLipo 15 yrs ago which got rid of most of the tummy fat, my only concern is the loose skin and lack of definition. I also don't want to lose the rest of the fat bc I don't want a cut abs, just light definition. My provider is suggesting a combo procedure - Emscult Neo (without fat burning) to build muscle, and Coolwaves by Odna (without fat burning) to tighten the skin. Is this smart and cost effective?
