Dear Jani,
The first thing I would do is go back to the physician who injected the Juvederm. It is unusual to have this sort of reaction for so many weeks after injection. If it is allergic (typically the reaction would begin with 24 hours after injection) than dissolving the product with hyaluronidase has been shown in some studies to alleviate the reaction. I would do the following:
1. Go see the physician who treated you and ask for a skin test using Juvederm. He/she will inject a small bleb underneath the skin of your forearm and will monitor the reaction over the next 48-72 hours. If you did not go to a physician for the treatment, I recommend going to see a dermatologist with a lot of experience with Juvederm at this point.
2. I would not recommend using Juvederm again. You may need steroids in order to bring all of the inflammation down. Again, I would trust the advice of a physician. In general HA fillers are pretty safe, but there are always exceptions. It is worthwhile to see a doctor rather than continue to feel discomfort at this point.
Best of luck,
Dr. Mariwalla
