Contains hyaluronidase with posology: 1500 IU dry extract powder/vials to be mixed with 10mL saline solution. Hyaluronidase is an enzyme that catalyze the hydrolysis of certain complex carbohydrates and depolymerize hyaluronic acid leading to its natural breakdown, therefore hyaluronidase is often used In aesthetic medicine, in fact in certain cases the body may consider injected hyaluronic acid, or some impurities of it, as a foreign molecule, so it could induce an immune reaction, such as the formation of granuloma; endogenous hyaluronidase that naturally present in the dermis will sometimes have no access to the ‘HA’ foreign body, so the product will be slowly eliminated through inflammatory reaction and phage cells.
