Risks of dissolving 6 year lasting Juvederm lip filler: will it permanently eliminate natural lip tissue? (photos)

Filler migration, swelling, and granulomas can cause significant discomfort and cosmetic ramifications. Our office specializes in the use of enzymes and filler reversal techniques without hyaluronidase to help improve the results of botched cosmetic fillers, whether caused by Juvederm, Restylane, or foreign fillers. Our plastic surgery institute provides expertise in filler removal. We begin by examining the facial fillers and assessing the likelihood of fluctuance or liquid volumization. If appropriate, we use Hylenex, or other filler reversal agents to reduce swelling and filler migration. Hylenex can be targeted into the areas of concern using multiple layered injection techniques. If the filler does not completely resolve, then additional concentrations may be employed. The technique has the potential to reduce the filler and may slightly impact normal hyaluronic acid. Treatments are repeated and results can improve immediately and with time.

Hyaluronidase will have best effects for over-treated areas when applied within a couple months post-HA filler injection, so with having hyaluronidase applied 6 years after your injection you are likely to remove some natural HA tissues. Patients who experience filler abnormalities often fear that all of their filler will be removed after having Hyaluronidase or that they will appear diveted and depleted. This is not necessarily true if injecting with an experienced injector who can evenly spread hyaluronidase in targeted areas. Some providers will actually dispense hyaluronidase injections in very small amounts to target certain areas without depleting all hyaluronic acid. 
I recommend that you seek in-person consultation with an experienced injector.

It is rare for a filler to last that long but if you do not like the volume of your lips you can certainly have it dissolved to see if in fact it really is filler or just your natural lip at this point.
