i'm overweight and trying to fight the "battle of the bulge". I haven't seen my neck in a while

I use Kybella for my patients with a smaller amount of fat below their chin.  If they have more fat I typically recommend Coolsculpting or liposuction because they tend to be more efficient and cost effective for larger volumes.  All are safe for you however.

Kybella can be a great option for reducing fat under the chin.  In patients with a small volume of fat and minimal laxity, it is usually the best option.  For patients with a little more fat, coolsculpting may be more cost effective.  In patients with more volume, liposuction is still the best option and if done well should have minimal downtime.  Seek out an expert who performs both non-invasive as well as invasive options to find out which option is best for you.  Best of luck.
