Kybella to the neck?

As the principal investigator for the FDA trials on Kybella,
and with over 400 treatments performed, we found that Kybella injections result
in significant improvement in the appearance of convexity or fullness
associated with submental fat. In these clinical trials, patients did not wear
a compression garment, and some patients did experience some swelling. The amount
of swelling is directly related to the amount of fat present and the amount of
kybella injected. In other words, if you have a large amount of fat under your
chin, you would require a greater amount of kybella to treat the area
effectively, and the greater the subsequent inflammatory response with
swelling. I currently recommend that patients wear a compression garment for a
few days to help with the post-procedure swelling. The procedure is very well tolerated by patients, fast, and
can be performed in clinic. Prior to any
intervention, however, a proper physical exam is necessary. I recommend
visiting a board-certified facial plastic surgeon who is experienced with
Kybella injections.

No harm in doing either but I usually don't find it to be necessary.  Arnica is very safe and can help bruising to resolve more quickly.  Some patients like wearing an elastic neck support but its up to you whether its worth the aggravation.  One thing that might be helpful next time is to take ZYRTEC (CETERIZINE) which is a non-sedating, over the counter antihistamine, with one pill the day before, the day of and the day after.  Easy to do and seems to help.

 Thank you for your question, both compression and Arnica are great options to help manage the symptoms after Kybella. I would also recommend that you do icing or cold compresses. If your office also offers lymphatic massage options, then I would also take advantage of this.
