Have smart lipo scheduled soon for a small amount of chin fat and some mild skin laxity on neck. I am 35 and weigh 117 lbs. I'm concerned I have overdeveloped submandibular glands and some platysmal banding that lipo will make more prominent. I asked about plastymal bands and the nurse said she's seen it get better or worse and they won't know at first. Should I be concerned this is not the right procedure for me?
