Why am I not swollen after Kybella?

I assume there is some confusion here.  Kybella is indicated only for under the chin.  I hope you didn't really have it injected under your eyes.   I cannot possibly fathom why anyone would inject it under a patient's eye.  

Thankyou for your question. I hope you have made an error in the name of your treatment as Kybella IS NOT indicated for under the eyes. It is only indicated for the double chin. I know people are using Kybella in other areas but i would be concerned about under eyes. You need to speak to your injector. 

As an oculoplastics specialist (expertise in eyelids and brows and eye sockets), I am aware of sodium deoxycholate injections (the active ingredient of Kybella) into the lower lid fat pads.  It is an "off-label" use of Kybella....but the first use of injectable deoxycholate for cosmetic reduction of fat WAS, in fact, on lower lid fat pads!!!!  It was done by Patricia Rittes, MD, a Dermatologist from Sao Paolo, Brazil.  She even received an award from the European Academy of Cosmetic Surgery for her work!  (She was one of my five teachers in these injections.)  I do not know why you did not swell under one of your eyes if you were injected there with sodium deoxycholate.  The medication kills fat, and the more fat, the more swelling.  And the more swelling, the more skin-tightening you will get (as proven by the excellent published works of Diane Duncan, MD, plastic surgeon from Fort Collins, CO, and another one of my 5 teachers in these injections).
I recommend you speak with the physician provider about it.

Kybella is definitely NOT approved for injection under the eyes and it would be very worrisome if you were injected there.  Kybella is currently only approved for the submental area.  Please consult an expert in Kybella for the best cosmetic results.  Best, Dr Green

You got Kybella where?   Under you eyes??  That would certainly constitute an off label use of the product. 

this is an off label use of Kybella. I would not recommend having this treatment. Swelling often picks up over several days. For those who understand the anatomy of the fat pads in the lower eyelid they would know better to try to inject Kybella there. The fat pads are deep to a membrane called the Peri-orbital septum. If the medication is not injected deep to this membrane it will most likely not get in contact with the fat pads correctly. Developing extreme swelling in the space can also put pressure on the eyeball leaving to blindness.  Please make sure you're being seen by a board-certified plastic surgeon or facial plastic surgeon or potentially an ocular plastic surgeon.  All of these specialties will have an understanding of the anatomy and potential complications that can happen.  These are not issues when using this product where it is FDA approved which is under the chin.  Best, Mats Hagstrom M.D.
