A hyaluronic acid (HA) filling treatment performed by an inexperienced specialist can often end up with complications such as asymmetry or lump formation. The acid may also move in the skin after the procedure. Fortunately, it is possible to dissolve unnecessary hyaluronic acid using hyaluronidase.Hyaluronidase containing substances depolymerize hyaluronic acid, commonly used as a filler in aesthetic medicine. Hyaluronidase locally degrades hyaluronic acid, which is later naturally excreted from the body.
