Dissolving filler in nasolabial lines: looks unnatural.

The medication used to dissolve filler is called hyaluronidase. It is an enzyme that dissolves hyaluronic acid (HA), which is the most common compound used for fillers. Other fillers, depending on what your injector uses, are permanent and cannot be dissolve. Those fillers must be removed surgically.

If your filler was HA (examples include Voluma, Volbella, Juvederm), hyaluronidase generally completely dissolves the filler. You could ask your injector to inject a lower dose but this is generally not how filler is dissolved. 

If you have an unnatural look after filler injection, it is either because of technique or poor analysis of your problem. I'd recommend going back to your injector and voicing your concerns. Most experienced injectors will be able to tell you if what your are experiencing is within the range of normal, or if your results are truly an error on their part.

Hi Sharon,
Reducing the amount of filler in this area is not difficult at all, as long as the filler used is a Hyaluronic Acid based filler. To do this, a physician will typically inject a small amount of an enzyme, called hyaluronidase, into the area that was previously treated with HA fillers. By injecting Hyaluronidase into the injection site, it is possible to reduce the amount of filler in this area without fully eliminating all of the filler injected. Keep in mind that it is best to wait at least several weeks to fully assess your results from fillers before you choose this option as you may still be experiencing swelling.
The fees for dissolving or reducing fillers are individualized by each physician, however, many physicians will not charge to reduce or blend filler products that they themselves have applied. It is always best always to seek a physician who is solely dedicated to cosmetic injectables.

I agree that an overfilled NLF can look "done" - especially when there are other signs of ageing on the face which may have contributed to the deepening of the NLF such as cheek descent. So, wait for the filler to settle. If it was hyaluronic acid, then hyaluronidase can be used  - its injected to the same area - but there is a small chance of anaphylaxis (severe allergic reaction) so make sure you see a trained nurse/doctor. If it was not an HA filler, then the solution is much more difficult if possible at all.
