It usually takes about 2 days for hyaluronic acid to dissolve by lysozyme, and it varies from person to person. Hyaluronic acid dissolving enzyme is a hyaluronic acid decomposition factor that can react with hyaluronic acid to make it dissolve and is mainly used to repair the failure of contouring. Generally, the dissolution can be observed in about 30 minutes, but the dissolution time may vary due to the different quality of hyaluronic acid in the market, and sometimes it cannot be completely dissolved at one time and needs to be dissolved by multiple injections of lysozyme. The elimination rate of lumps caused by hyaluronic acid over-injection can reach 90%, and the dissolution effect is usually more obvious around 2 days, and the remaining small amount of hyaluronic acid needs to be absorbed by the body, which can be completely absorbed around 2 weeks. After the injection of lysozyme, patients need to pay attention to avoid contact for a day to avoid deformation and not to apply cold or hot compresses. In addition, strenuous exercise should be avoided and it is not advisable to go to places with high temperature.
