I have a generic disposition for "turkey neck" and fat collecting around my jaw. I received Kybella (2 syringes) under my chin and jaw to dissolve the fat and tighten the skin in this area. It takes 4-6 weeks to show complete results from one treatment, so I will update with swelling and the final outcome. Updated on 15 Jun 2021: There was significant swelling, but it wasn’t painful. It was akin to a “deep” bruise. The area was sensitive at first, but now I’m 2 weeks out and there is still some swelling, but not noticeable. I still have numbness, but it has been decreasing. Looking forward to the end result.
