Your photo is very helpful.  They show that you would benefit from neck rejuvenation.  Direct excision is not a great solution as the scar form that procedure is problematic for many reasons, not the least of which is that it is very unsightly.  A very simple approach would be a lower MACS lift that deals with the neck.  The beauty of a MACS lift is that is scars can hardly be seen and it gives a very natural look that will last for years.  It can also be done in the office setting under local anesthesia, which some patients prefer.
I have added a video of a patient who had this done that may be of help to you as well.
