Thanks for sharing. In general, current neck and lower face rejuvenation treatments include:Surgical Neck lift* with a Lower Facelift would be the gold standard and gets the best overall results in the jowls and neckSurgical Neck lift* which removes skin 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 tightening)Ultherapy 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 activity and 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. Based on your photos, you do have excess skin and muscle. I feel that a lower face and or a neck lift would give you the best results and satisfaction. You do look like an excellent candidate. Talk to several board certified surgeons experienced in face and neck rejuvenation to discuss your options.

A neck lift is not a singular procedure with a singular #method, but rather is an umbrella term describing a large range of operations with varying #incisions and skin-lifting #techniques, which have been developed and improved upon over the years.  Your board certified plastic surgeon will be familiar will be able to pair you with your perfect match of surgical approach based on your skin type and desired results.  The type of neck lift incision will depend upon your gender, your hairline and preferred hairstyles, any scars from previous surgeries, and a variety of other factors.  As a general rule, a #neck lift #incision starts right in front of or within the hairline on the temple, follows the curve of the front of the ear, travels underneath the earlobe, and ends at the hairline behind the ear.  There are also shorter #scar techniques preferred by many patients, which do not have incisions in the hairline.  Some patients who wish to have liposuction or tightening of their neck will need an additional incision under their #chin, which can be hidden in a natural skin fold.
The #scars will mature within six to twelve months from the surgery date. It is during this time that the rejuvenating effects of the facelift will become apparent and the real result will be seen. We find that scar reducing product, BioCorneum, appears to be very effective. Consulting with a board-certified plastic surgeon who specializes in #neck lift procedures is important to ensure you are receiving the best advice, care, and surgical experience possible. 

Platysmaplasties do well and are easy to undergo under local. The under the chin incision is hidden very well and I usually do a little lipo along the jawline to trim surrounding fat at the same time.
