Photos would have been helpful. However, in general, age-related skin sagging and jowl formation can be easily and quickly treated these days (engendering immediate "Wow!" reactions) via use of injectable volumizing fillers. In general, volumizing fillers placed in areas such as the cheeks can improve not only the under eye area, but regions below, such as the smile lines and to some extent the marionette lines around the mouth and the jowls along the jawline. Volumizing filler placed in the chin region not only increase chin projection that comes with age-related volume loss, but helps to straighten jowly jawlines. Moreover, volumizers placed directly in the appropriate pre- and post-jowl indentations can further help to lift and straighten sagging jawlines. You would do well to consult with an experienced board certified aesthetic physician and be sure to ask to see his/her before and after photos before agreeing to proceed. Best of luck
