Uneven lip correction —any suggestions? (Photos)

I went to an inexperience injector. What I was told, the injector had placed Juverderm in my upper lip. It created scar tissue & stretched my lips, lumps & created unevenness overtime. I’ve tried dissolving. Refilling & PRP treatments. There is no product in my lips, just soft scar. I’m nervous about the pain associated with lip surgery & this is why I didn’t considered it. If surgery is the only solution I am open to it now or anything else.
