Overfilled tear trough. What now? CO2? Which type? (Photo)

Overfilled tear trough under one eye 1yr ago, partially dissolved 5mths later, still overfilled and left lax, wrinkly with pits everywhere hyaluronidase went. I can literally see the outline of where it settled and destroyed my face. Other than being dissolved the filler hasn’t broke down at all and I assume from what I’ve read I’ll never look the same. Will co2 help tighten up and maybe smooth over the filler better making it less bulgy? What type of dr should perform this procedure? Thanks
