I have a BMI of 25.9, and am considering Trusculpt iD for double chin. My mother and grandfather had them, which seemed at least partially to be from the structure of their face/necks rather than solely from extra weight (though they were overweight). I’m very healthy and active. Is this the right procedure? If I gained weight after at some point in the future, might there be lumpiness/unevenness? What is the risk of lymphatic drainage issues when Trusculpt iD is done in the chin area?
