I’m 35 and I’m looking for a non surgical way to get rid of my double chin that is mostly fat rather than sagging skin. I am fairly thin but can’t get rid of the double chin. Most importantly, I have a history of thyroid cancer and want to make sure whatever I choose is safe and won’t put me at risk for recurrence since it’s in an area close by. I also would like to know which one of these is most effective: morpheus 8, vivace, or sculpsure. Thanks!!
