I'm 100lbs overweight, had Kybella twice, it's been months since and there's no improvement just low and jiggly skin. Advice?

This is difficult to answer without pictures, but you might not be a good candidate for Kybella, based on your description. I find that VASER liposuction in combination with ThermiRF are best for contouring the chin in those who are candidates and can be combined with a neck lift at the same time, if needed. Kybella can be used as an alternative, but it needs to be combined with thermage/ultherapy/exilis or coolsculpting for good results. I recommend getting a formal evaluation with a facial sculpting expert. Typically if you are overweight however, this needs to be addressed first before cosmetic enhancements to get the best outcomes. Best, Dr. Emer

Kybella helps remove the fat but it will not tighten the skin. It you need skin tightening then you would require a neck lift. 

Thank you for
your question abryant1218. Kybella is
the first and thus-far only FDA-approved non-surgical injectable treatment for
the double chin. The double chin can be caused by weight gain, age, and genetics. In extreme cases many patients find improved results by starting with Cool Sculpting and then having Kybella. Additionally most patients require 2-4 treatments, sometimes up to 6 treatments. At that point final results should be assessed with photographs. Skin tightening can be performed with fractional CO2 laser resurfacing. Please
consult with a doctor for specific recommendations. Good luck!
