I am 35 years old, 5'6" and weigh 124 lbs. Regardless of my weight (even at 110-115 lbs in my younger days), I always have a pocket of fat under my chin that I just hate. I believe it is probably hereditary. I recently met with my doctor to discuss Kybella and then left to do some additional reading and make a decision. I honestly expected the procedure the be more expensive and something I would start saving for, so I didn't do as much research as I should have prior to visiting with her. She thought one vial/treatment would be sufficient to help me. My questions are below:-Should I be concerned about sagging skin after the fat cells are dissolved? My skin's elasticity is not what it once was, but it's not terrible either.-I am growing more and more concerned about swelling after reading additional reviews. Will mine be less since I am only having one treatment? 4-6 weeks of swelling could be very difficult to deal with. I am noticing a difference between doctor's statements on swelling versus patient's. It also seems to make a difference if the reviewer had 1 treatment versus 4 or 5. Regardless, I will wait until after the holidays just in case of pro-longed swelling.-Really, how bad & pro-longed is the pain?Thank you!
