Will my migrated lip filler eventually resolve? (photos)

Swelling in the face can last months. This is particularly true around the eyes, nose, and mouth. It is unlikely that this is scarring or anything permanent. I would give it time before pursuing any other treatment, at least 6 months.

I'm sorry to hear of the issues you had with filler. Depending on the filler used, it will take approximately six months to a year for it to be gradually metabolized. You can consider further hyaluronidase treatments if desired.

Sometimes HA fillers can lead to long-term contour changes that are not explainable. Personally, I don’t believe fillers migrate.
The term is a poor excuse for simply injecting badly.
I’m generally cautious about overfilling the upper lip, especially along the vermillion.
At this point I suggest giving this time.
If reversal injection did not produce the change you wanted then doing more of the same makes little sense. Try to find some pictures of your lips pre filler and always include before and after pics them possible.
I don’t think there is any good solution than giving this more time.
Best,
