Should hyaluronidase be used diluted with saline or undiluted to remove stubborn Voluma/Vollure over large area?

Longterm filler problems include migration, edema, and nodularity. Filler migration and permanence is a very common problem because there are many different types of HA fillers on the market and each is specified for a specific part of the face. Use of highly cohesive fillers on thin skin may cause swelling and nodularity. If patients have filler migration or nodules, we recommend a combination approach of filler reversal with enzymes Hylenex and Hyaluronidase in different strengths to dissolve the filler. We may also need to add Kenalog to the mix in order to reduce fibrous tissue. If the filler does not dissolve, it either means the filler is not HA material or we need more enzyme. The HA reversal can be combined with other lasers and skin treatments at the same time, and it usually (usually) does not affect adjacent tissue.

This needs an in-person evaluation. The filler can be dissolved with hyaluronidase. Keep in mind, it will take a series of treatments. Best, Dr. Emer

Dear Xangelika,
Hyaluronidase is more potent when used undiluted since there is a higher dosage of the medication in the volume injected. It is best to inject it directly into the area where the filler is located and oftentimes can be felt. Multiple series of injections are usually needed to dissolve all of the filler and certain types of filler are more resistant to hyaluronidase than others. I would recommend consulting with a physician that is experienced in these injections.
Best,
Dr. Liu
