Can Cool sculpting be used to reduce upper arm sagging fat -63 y.o.?

When skin has good elasticity, the upper arms can get good results with fat reduction both with liposuction and CoolSculpting (off-label) and the skin will shrink back into position. In some patients, a lack of elasticity can create a seemingly looser skin after either liposuction or CoolSculpting. In our NYC practice, ThermiRF, a relatively recently FDA-cleared device has shown promising results when done on the upper arms and face, neck and other body sites. It delivers controlled heat via radiofrequency, while monitoring internal temperature at the site of treatment and checking external skin temperature for safety. This heat tightens the connective tissue support of the skin, and induces new collagen growth below the epidermis to induce more tightening over three to six months after the procedure.The information provided in Dr. Shelton's

I have had very nice results applying the safe CoolSculpting technology to fat of the arms.  You need an evaluation to look at the quality of the skin, but it is absolutely a potential option.  Good Luck!
