Generally, unsatisfactory appearance, over-injection, left-right asymmetry, unevenness, swelling and other unwieldy phenomena after hyaluronic acid injection can be solved by injecting hyaluronic acid lysozyme. Hyaluronic acid lysozyme is an alkaline protein that can be used to repair the failure of contouring, and its recovery period needs to be determined on a case-by-case basis. If the lump is caused by over-injection of hyaluronic acid, hyaluronidolytic enzyme can be injected within 48 hours, which is effective in 1-2 days and can be completely absorbed in about two weeks. The following points should be noted when using hyaluronic acid dissolving enzyme: 1. Hyaluronic acid enzyme should not be injected within 48 hours of the site where botulinum toxin has been injected, because hyaluronic acid enzyme can contribute to the serious spread of botulinum toxin; 2. Some people with acute and chronic diseases and those who are taking oral medication, especially those with a history of allergy, should avoid using it; 3. The interval between injecting hyaluronic acid after injecting hyaluronic enzyme and then injecting hyaluronic acid is generally a more secure interval of one week If it is urgent, the interval should be 72 hours, which is related to the absorption of drugs; 4. Choose regular institutions for hyaluronidase injection to ensure safety and reliability.
