HA Fillers can be dissolved with hyalase, even after a year of placement. Several sessions may be required to achieve the desired outcome, and sometimes controlling the amount dissolved might not be possible. As such you may need to undergo the dissolving, then a touch up with fillers a few weeks later.
Other fillers such as Non-HA fillers (like Radiesse, sculptra and Ellanse) are not really affected by hyalase and cannot really be dissolved.

Hyaluronic acid (HA) fillers can be removed using Hyaluronidase (Hyalase).
Usually 1 session is needed. However, for HA fillers that still remain even after 1 year, more sessions may be needed for best results.
Hope that this helps!

Yes, hyaluronidase can be used to dissolve away hyaluronic acid fillers, no matter how long ago they have been put in .
This is due to a hydrolytic chemical reaction which the by product is water molecules. So as long as it’s hyaluronic acid, it will become water when hyaluronidase comes into contact with it.
I have successfully dissolved a certain brand of HA that always causes avatar noses of patients from other doctors before, as they persisted for up to 2 years after injection.
