Best Procedure for Double Chin?

Thank you for your question. There are several options for contouring the double chin area.Non surgical options include: 1) Kybella to dissolve the fatty tissue in the submental area 2) Cool-mini treatment from Coolsculpting to target the same area 3)
Adding a skin tightening device such as Ulthera or Profound to the neck
tissue in conjunction with the one of the above to further tighten the
skin. Surgical options include: 1) Straight liposuction which would reduce the pinchable fat under the chin2)
Anterior neck lift with liposuction which would also allow for
tightening of the platysmal muscles in the midline to allow for tighter
neck contour3) Traditional neck lift which does the same as 2) but also removes some excess skin in the neck.I
would recommend that you visit with a board certified plastic surgeon
who offers the various options above to discuss the pros/cons of each
option and help you decide which is the best for you.

Options for a double chin are plentiful now.  They range from neck liposuction, coolsculpting, or kybella.  If you are over the age of 45, in general, you want to talk to your plastic surgeon about how you will address any skin laxity that could be present after fat reduction.  All of the modalities above offer mild skin tightening but it's not a necklift. 

Liposuction is usually an amazing, less-invasive alternative to conventional neck lifting. I would advise a consultation for liposuction with or without laser to tighten the neck and jawline.

The best procedure for a double chin might be two procedures. Often a double chin appearance is created by a small chin as well as excessive fatty tissue in the immediate submental area (the area below the chin in the neck). The best treatment is to remove the excess fatty tissue in that area and strengthen the chin line which will give a better neck and jaw profile. If you are over the age of 45, sometimes a necklifting procedure may also be required for excess skin and sagging, but otherwise the other procedures are sufficient. If your chin line matches your lower lip on the side view, then it may be sufficient to just perform fat removal or liposuction just below the chin.

You should consult a board-certified facial plastic surgeon to discuss which surgical options would be best for you. Neck liposuction works well in younger patients with a strong chin. Sometimes a Chin Implant is needed to improve your appearance. And depending on your age, sometimes a formal neck-lift procedure is necessary.
I hope this is helpful, and best regards.
