Restylane is a great product used for injections in the face. However, if you have a bump three months later I would recommend that you return to your treating physician for examination and Vitrase to be injected to help resolve the bump.
Thank you for the question. Without a photo, it's difficult to make a specific recommendation. However, hyaluronidase (Vitrase) can be used to dissolve the filler if this is indeed the problem. After injection of the enzyme, gentle massage and a warm compress can be used. Small doses are best, as the enzyme can affect your normal tissues as well as the filler.
Please post photos for us to help you. There is no way we can make a suggestion without it. However, using hyaluronidase is not a bad decision and will have no consequences except for removing any of the product that is cauing the bulging and swelling in this area. Best, Dr. Emer.
