Will hyaluronidase injections dissolve the Juvederm after 3 years?

Juvederm can last three years under the eyes.  Hyaluronidase can be injected to dissolve product. Good luck

In general, Juvederm lasts for 6-8 months on average. It is unlikely there is any Juvederm left after 3 years, which is what your physician may have been speaking of. It is difficult to provide advice without seeing photos or performing an exam. I would recommend following up with your physician, as he/she will be able to advise you after seeing you in person. I hope this helps, and I wish you the best of luck. 

The issue that your injector brought up is not that Juvederm can't be dissolved after three years. I think their concern was that the Juvederm is long dissolved and that hyaluronidase won't make much of a difference. It's worth a shot and I'll usually treat people conservatively with hyaluronidase even a couple of years following filler treatments at another office. There is very little risk and a reasonable chance that things will improve following hyaluronidase treatment. I hope this information is helpful.Stephen Weber MD, FACSDenver Facial Plastic Surgeon
