Can Kybella cause under eye swelling?

Thank you for your question.  Kybella works by dissolving fat cells which lie just below the skin under the chin and jawline.  As the fat cells dissolve, this gives definition to the submental (under the chin) region.  A side effect is swelling and numbness under the chin, but you should not have swelling under the eyes after Kybella.  I would discuss this reaction with your injector, as well.I hope that this helps!-David Gilpin

It is very unlikely that the Kybella injected is related to the under eye swelling.  The inflammation is usually localized to the area injected.  

It is not likely that Kybella has anything to do with the swelling under your eyes.  Unfortunate timing, but Kybella will only cause swelling and an inflammatory reaction in the area that it is injected.  Best of luck with your ongoing injections.  In my experience Kybella is doing a very nice job of what it's intended to do for my patients.Dr. Henstrom

Kybella only gives local swelling if you had this done on your chin/neck it wouldn't affect your eyes.  Best, Dr. Emer.

Thank you for sharing your question and I am sorry to hear of your swelling.  Assuming the Kybella was only injected into your submental region it unlikely to have directly caused your under-eye issues, and as you mentioned it is likely an inflammatory response to treatment that should spontaneously resolve.
