What Type of Doctor is Most Qualified to Inject Filler Under the Eyes?

I realize that many doctors can be qualified to inject fillers, but what type of doctor would be the best qualified? I had perelane injected under my eyes over a year ago that left a bump under one eye. It is still there. I've been waiting for it to go away on it's own, but I'm getting impatient. I'd like to get it dissolved and re-done. However due to my last experience, I want to make sure I go to the right person.
