Is there anyway to get rid of my lumpy lips from fillers from over 4 years ago without in advice surgery? (Photo)

I've had my lips injected with d ultra plus over 4 years ago. My lips never went back to normal. I went to a plastic surgeon and he said that it wasn't silicone (thank god). But it might be scar tissue? I'm very self conscious about this I feel like everyone stares at my lips, and not in a good way. Is this fixable with out gettig more filler to fix it? Can it be dissolve
