Can I use Kybella to reverse facial fat graft to my cheeks?

Know one knows. Kybella causes tremendous inflammation and can lead to nerve damage.  For that reason and it enormous cost, tempers one's enthusiasm to explore off label uses of Kybella.  I see 3 to 4 new consults each week for folks who have been damaged by fat grafting.  

I’m sorry you are unhappy with your fat grafts. You didn’t mention when your procedure was done. You will be swollen for up to a few weeks. It also takes awhile for the grafts to “settle.” I wouldn’t recommend Kybella to melt the fat, though. It works best on submental fat and jowls. If you are still unhappy after a couple of months, consulting a board-certified dermatologist who is an expert at contouring the face will help resolve any asymmetry using very subtle amounts of hyaluronic acid fillers.

It's possible this could work on some parts of the face, but I think it would be high risk for nerve damage. Have a formal consultation about alternatives to Kybella with an experienced injector.
