Is my top lip migrated and should I consider having it dissolved? (photos)

This will not "wear" off. The lip shelf is from overfill and migration. It looks unnatural. This will need to be removed with enzyme. The tissue should be allowed to recover 10 to 15 days before the filler treatment is replaced with a higher G prime filler. The best of these is Restylane. The Juvederm and most fillers intended for the lip edge are runny and very likely to cause a similar lip shelf. Going to an injector who actually knows what they are doing is helpful but easier said than done. I would not let the injector you saw to the enzyme treatment. You will need about 150 units of hyaluronidase for that service. So sorry you experienced this. Lip treatment should be natural and it is possible to have that type of service.
