I have a pretty good size double chin with moderate laxity. I'm worried about side effects, residual skin sagging, losing volume in the lower areas of my face like I've read is a possibility with the other 2 procedures. I have good skin tone above my jawline but have always had fat beneath chin made worse by weight gain, weightloss does not change it. I'm 52. Basically want to lose the awful old lady drooping bubble that has increasingly gotten worse and tighten up the jaw and neckline a little.
