There can be swelling, redness and inflammation for several days after a Kybella treatment. There is no real down-time with Kybella, but I recommend following your Doctor's protocol regarding exercise after your treatment. Keep in mind, Kybella is good for dissolving fat under the chin, but a combination approach is needed to get the most improvement with non-invasive options. I recommend a combination approach with thermage, ultherapy, exilis. VASER liposuction in combination with ThermiRF is the best alternative for contouring the chin, if you're a candidate. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer
