For me, the confidence it gave me has really made we go from looking for that may been accepting me to looking for those that don't accept me and finally to simply not caring and just living my life.
This isn't a physical benefit of the procedure, but a side effect of knowing that my nose and jaw are less bulky and not having a barrel neck anymore and actually having more than just what looked like moobs.
I also had breathing and smelling issues with it totally relieved.
