Hyaluronic acid dermal fillers can be reversed with an injection of hyaluronidase.
Hyaluronidase is an enzyme that catalyses the breakdown of hyaluronic acid. It is used to reduce excess filler, uneven filler or incorrectly placed filler. Note that hyaluronidase does not work on permanent or semi-permanent dermal fillers. Its action is very quick and will work immediately after injection.
