Is there a doctor in the Dallas, TX area that can fix a botched lip filler?

I had a doctor who was supposed to add fillers to my top and bottom lips with Restylane Silk but messed up the bottom lip, he injected under the bottom lip instead of the lip itself. This was done at the end of May 2015. The under part of my bottom lip is slowly coming down but I would love to have the filler dissolved and have normal lips which could eventually be injected properly.
