I am 66 years old and I hate the sagging on my neck and jowl area. What treatment do you suggest?

Lower face-neck lift for 66 year old

From your limited description it appears that you would benefit from a
lower face-neck lift. In my practice a patient with your presentation get a
significant rejuvenating effect from this procedure with rather rapid recovery.
Seek out an experienced and talented surgeon for in person consultation. Review
the surgeon’s before and after photos to assess the type of results that you
might expect for yourself.

Based on your age and the areas that you mentioned, I think you would be a good candidate for a face and neck lift.  I would love to help you with it if you are interested in traveling to Austin.
