Can I dissolve filler in distinct spots or does everything dissolve in a seamless way?

Hyaluronidase is the enzyme that dissolves hyaluronic acid fillers.  It can be administered in very small aliquats to precisely dissolve unwanted hyaluroinc acid filler.

Hylauronidase has many advantages and should be considered in patients who are unhappy with their results or in acute cases of overfilling or occlusion. Its often better to reverse filler and restart then to deal with long term edema. Filler migration and permanence is a very common problem because there are many different types of HA fillers on the market and each is specified for a specific part of the face. Use of highly cohesive fillers on thin skin may cause swelling and nodularity. If patients have filler migration or nodules, we recommend a combination approach of filler reversal with enzymes Hylenex and Hyaluronidase in different strengths to dissolve the filler. We may also need to add Kenalog to the mix in order to reduce fibrous tissue. If the filler does not dissolve, it either means the filler is not HA material or we need more enzyme. The HA reversal can be combined with other lasers and skin treatments at the same time, and it usually (usually) does not affect adjacent tissue.

Good question! Best to go to your original injector who should know where the HA was injected. There is no exact science in terms of predictability as to the impact of the hyaluronidase injected. Hope this helps. 

Thanks for your question.  It may be challenging to inject hyaluronidase and get it to stay so localized within the chin that you dissolve only the filler that you want to dissolve and keep the parts you want to keep. Maybe not impossible, but I think it will be hard to do. You are better off waiting for the filler to reabsorb completely or have it completely dissolved with hyaluronidase, then redo the chin augmentation in a fashion that pleases you. Just my opinion based on what you have said and without any photos to go off of. Best of luck to you.

Many rely on dissolving agents after uneven fillers however make sure you go back to the same physician who placed the initial fillers for dissolving the affected area for evenness

Your injector can put in small amounts of the dissolving agent to be as precise as possible. But it is a liquid and it can spread a bit. Just remember that removing filler is just as much an art as putting it in to begin with, so seek an expert. "This answer has been solicited without seeing this patient and
