If you have coolsculpting on neck will it leave the skin to sag with an older person?

Coolsculpting under the chin will get rid of a lot of the excess fat in that area. If you have a lot of fat in the area or if you already have some sagging and your skin is not elastic or stretchy, then you could end up with some sagging skin. See someone with extensive experience with the face. I wouldn't just trust a coolsculpting spa to give you the correct recommendation.Andrew Campbell, M.D.Quintessa Aesthetic Centers

I attached my video, which references Kybella but can just as easily be substituted for Coolsculpting -- I encourage you to watch it.  If you debulk or remove fat from a neck with loose skin and poor skin elasticity, the skin will essentially resemble a deflated balloon. In these instances, a neck lift, where skin can also be excised, may be a better option.  Visit with a facial plastic surgeon or plastic surgeon to discuss your individual condition and devise a plan tailored to your goals. Good luck!
