You don't specify why you are looking into a new fat-loss technique one year after your submental liposuction. Were you dissatisfied with the results? Or did you regain weight and now need another treatment? In either case, Kybella can effectively remove your submental fat using deoxycholic acid. It will probably take at least two to three treatments to get the results you want. If you need re-treatment because of weight gain, please be sure you have your diet and exercise regimen under control before receiving Kybella. While it will remove your submental fat, if you gain more weight, the remaining fat cells may expand to accommodate the extra volume and your benefits will not be visible until you lose weight again. Please see a board-certified dermatologist to see if you are a candidate for Kybella.
