does sculpsure tighten the skin at all? also, with each treatment, is it consistent 20-24% loss of fat?

SculpSure does not currently have FDA approval for use as a skin tightening device.  There are some physicians who feel that there may be some skin tightening with the treatments and it is something that may be studied in the future.  At present, I would not have the treatment to specifically address skin tightening, but for fat reduction.  Repeated sessions of SculpSure can be performed to obtain additional fat reduction.  A single procedure can destroy up to 24% of fat cells in the treated area.  Additional treatments will also destroy up to 24% of fat cells.  

Since SculpSure is a laser and therefore uses heat, the treatment is associated with some skin tightening. But it is primarily about fat loss. The 23% fat reduction is the total amount. I find that most patients need at least 2 treatments. Hope this helps.
