Can my under eye be smoothed out? Could it be leftover filler after dissolving 1 year ago? (photos)

Here’s a plan that hopefully you will accept and practice. I would continue with small doses of hyaluronidase administration until the filler is completely dissolved. Never try to put a lot of hyaluronidase in the area at once. Once the area is void of the filler, I would recommend having fat grafting done to the area to create the best and most natural results which when are well done are permanent. I hope this helps and good luck from New York City Plastic Surgery

You need more filler but you need to see an expert injector for a consultation.
Restylane L is always best for tear trough!
Best of luck!
