Do I need lower facelift or can be corrected with kybella or cool sculpting? (photo)

It appears that anything but face and neck lift will be short of satisfactory result. In your age that is an excellent procedure to correct current "deformity" of neck and lower face, improve jawline and provide long lasting natural result. Addition of fat grafts in cheeks and around eyes/eyebrows would contribute to youthful fullness of the midface.

The most important think in this adventure is to find a board certified plastic surgeon with good reputation in facial rejuvenation surgery. Good luck. 

Based on your photos, you would receive a better result with a face and neck lift, rather than kybella and non surgical tightening. See a qualified and experienced surgeon for a consultation.
