A few years ago, I would have said no and told you to please not waste your money with offices making false promises.   But ...........   now there's beginning to be some very interesting data on "off-face" applications of several of the newer fractionated CO2 lasers. I think there's some hope here. The best lasers for this, in my opinion, are the DEKA DOT and the Lumenis Active/Deep Fx.  And, only go to an office with experts if you decide to pursue this now.  Look for groups who have published scientific papers in this area.  The risk of scarring is greater off the face.  

Also, this laser won't make a noticeable difference if you have a lot of loose skin.  The muscle underneath has to be pretty firm and the skin can't be hanging loose, just crepey.   It's fine to have some fat there but not too much.    Hope this helps!  Dr. I
