Injection of hyaluronic acid, injection site to eliminate swelling factors, the effect is not ideal, lysozyme can be injected at any time, it can dissolve the injected hyaluronic acid, not limited by the site. However, if there is abscess or infection in the relevant parts after injection, it is necessary to delay the injection, treat the abscess first, and then inject lysozyme after recovery. Lysozyme can eliminate the filling effect of hyaluronic acid by decomposing crosslinking agent. Lysozyme can make the injected hyaluronic acid lose cross-linking and become countless small molecules of hyaluronic acid, which are then naturally absorbed by the human body. The action time of lysozyme also depends on the concentration. If the concentration of lysozyme is high, it will dissolve in a few hours, but it will not be used clinically, so it usually takes about two days to dissolve.
