I had lip fillers in September of last year and I'm not happy. How can I correct them? (photo)

Hyaluronidase is very quick to dissolve hyaluronic acid fillers, which I assume you had.  I would start back at square one and get someone else to fill them.  Hyaluronidase needs to be injected into the areas of filler just as if you are getting filler.

Lopsidedness from fillers can be corrected with hyaluronidase. I am assuming you had either Restylane or Juvederm put in (both times) and so hyaluronidase can be injected and will work to dissolve these lumps. Without knowing exactly what filler(s) were done on you, it's hard to say, but this is what I'd at least start with. "This answer has been solicited without seeing this patient and cannot
