Neck Lift v. Lower Face Lift v. Chin Lipo - I'm confused! (Photo)

The only way to know for sure which treatment plan will be best to achieve your goals is to be evaluated by someone who is not limited in their approach to treating the neck, surgically and non surgically.  It does become confusing when you get different recommendations from different doctors, but it is not a surprise. Every physician has their own philosophy and approach.  It may help to consider that aging comes in different patterns and is unique to each patient.  Treatment recommendations will vary from surgical to  nonsurgical, such as radio frequency, laser, ultrasound, and injectables.  One thing to understand is that if the neck muscles (platysma) are loose, the only treatment that will effectively tighten the neck will be a surgical neck lift. Nonsurgical treatments focus on tightening skin. If the lower face is contributing to the looseness of the neck, then it is worth considering combining a neck lift with a lower facelift. In the right patient, nice results can be achieved with liposuction combined with laser or radio frequency skin tightening. 

Thanks for sharing. In general current neck rejuvenation treatments include:
Surgical Neck lift* with a Lower Facelift would be the gold standard and gets the best resultsSurgical Neck lift* would be the next best procedureNeck liposuction and/or laser lipolysis if only fat removal is required, typically in a younger patient. A platysmaplasty can be added for further muscle tighteningUltherapy is an FDA approved non invasive tightening using ultrasound technologyKybella is a new FDA approved injection that melts fat under the chinBotox to the platysma bands to decrease their show*It is important the a Neck lift involves some liposuction and importantly a platysmaplasty which is a procedure that tightens the underlying loose neck muscles. 
You are at an age where you may fit into either option 1,2, or possibly 3 as you have described.  It is likely that you may need some type of surgical neck lifting to tighten the platysma muscle and remove loose skin. I would have to see you in person to make definitive plan of action. Talk to several board certified surgeons experienced in face and neck rejuvenation to discuss your options.
