The jaw line cannot be completely improved with facelift alone unless liposuction is done to reduce the amount of fat along the jaw line. Once recoveries completed about 6 months to a year you can opt to undergo a revision surgery that should include liposuction as well.RegardsDr. J
You are still early in your recovery. Its best to wait longer to see your final result. However, if you are still not happy with the definition of your neck, its possible you might need further surgical procedures. I would not consider a non invasive alternative unless you were evaluated for a personal consultation. Its possible more platysmal work or sub platysmal work might be helpful if not originally done, and it would be surgical if needed.
You are still healing from your procedure. maintain a garment on your neck to reduce swelling. Discuss your concerns with your physician. it currently from photograph posted looks pretty good. Hope your recovery goes better, good luck...
