A combination of non-surgical options like Kybella, PDO NovaThreads, Ultherapy and Thermage would do well in combination for skin tightening for the neck. VASER Liposuction (with ThermiRF, Renuvion and InMode FaceTite) is a great alternative for contouring and tightening the chin and neck and can be combined with a neck lift at the same time, if you're a candidate. I suggest getting a formal evaluation with a cosmetic dermatologist to develop a long-term treatment plan that works for you. Best, Dr. Emer.
Might consider "PRECISION SMART LIPO LIFT", ThermiTight RF Lift, Fat grafts or Voluma fillers, and finally a mini facelift. Or combination of all three...
