Is 6 weeks after Voluma injections too late to have it dissolved? Are the side effects to the filler removed?

Voluma is made out of hyaluronic acid. It can be dissolved with hyaluronidase at any time. At 6 weeks, you may still be having some left over swelling or asymmetry from the injections, so it may be a little soon to try and dissolve the filler. I usually have my patients wait a little longer (2-3 months). But, it depends on what your specific issue is. With Voluma, because it is more solid than the other hyaluronic acid fillers (Juvederm, Restylane, Belotero), it will take more hyaluronidase, and it may take more repeat attempts to dissolve it before you achieve the goal of smoothing out a lump or bump.

A hyaluronidase such as Vitrase may be used to dissolve Juvederm Voluma at any point after it is injected.  Typically it is prudent to wait at least 2 weeks to allow the bruising and swelling to resolve, and the filler to settle, before dissolving it.  After this point, Voluma may safely be dissolved at any time, including 6 weeks after injection.    

It is safe to have Voluma or any hyaluronic acid filler dissolved with Hyaluronidase at any time.  A higher concentration of Hyaluronidase is needed for a Voluma vs other HA fillers so make sure you go to am experienced injector for this treatment.

There is no time limit to dissolving Voluma, or any other of the the hyaluronic acid fillers.  As long as there is some unwanted product present, it can be dissolved with hyaluronidase.  The main possible side effects from having Voluma dissolved would be those associated with any injection.  So, I would say it would be possible to have some bruising with the treatment.  

Fillers made of hyaluronic acid that haven't been metabolized by the body yet or haven't dissolved yet can always be dissolved with hyaluronidase. Please contact a qualified provider or a board-certified physician with extensive experience in these procedures. Hyaluronidase is designed to dissolve fillers made of hyaluronic acid. Minor bruising, swelling, and discoloration to a degree are normal.
