The Kinetics of Reversible Hyaluronic Acid Filler Injection Treated With Hyaluronidase

BACKGROUNDHyaluronidase is an enzyme capable of dissolution of hyaluronic acid (HA). There is a lack of evidence-based research defining time- and concentration-dependent reversal of HA filler using hyaluronidase.OBJECTIVETo explore the efficacy of different concentrations of hyaluronidase in digest
