After coolsculpting, does skin on older people (I'm 72 years old) tighten up or does it hang.

Hello. I would recommend that you meet with a board certified provider in order for them to asses you to see if you are a good candidate for CoolSculpting based on your cosmetic goals. Keep in mind that CoolSculpting is a fat reduction procedure, not a skin tightening procedure.

Coolsculpting is a procedure to kill off fat, and generally does not do much for the skin.  With that being said we have seen the skin tighten for the average person, however in your case you may have more than just a normal amount of skin laxity due to age and thus an in person assessment would be suggested so that your treating physician can determine whether any worthwhile change in your skin would be noticed.
