Hyaluronidase is an enzyme present in products used to remove certain FDA approved facial fillers. It is injected under the skin to speed up the natural disintegration of hyaluronic acid, which is the active ingredient in some facial fillers
Hyaluronidase is used to dissolve hyaluronic acid fillers that have been placed incorrectly, excessively, or unevenly. It is injected into the same locations that the filler already is. It does not remove all of the filler entirely.
Because, like the fillers themselves, this treatment uses a naturally occurring bodily material, this treatment is very safe. However, there is a small risk of an allergic reaction to the hyaluronidase injected.
