Was treated with Kybella. There was no burning/pain w/ injection. Did it not work? There is significant swelling (Photo)

Thank you for your posting and pictures.  Swelling is common post Kybella. Because you did not experience any pain or discomfort during the procedure doesn't necessarily mean that it wasn't injected properly. Some people have different pain responses to injections.  It may take several weeks to see optimal results and in some cases patients do multiple treatments to reach their aesthetic goals.
