4 years after Restylane Defyne, inflammation is still present. What can I do to correct this? (photos)

I had a lip filler injection with Restalyne define in August 2019. A lump formed where the filler was injected and was causing a symmetry. I received two separate doses of Hylenex and the bump went away but the area is still noticeably inflamed. It doesn’t feel like there’s any filler left in it but is there any options to get rid of this? Thanks.
