Hyaluronic acid has long been popular worldwide as a cosmetic filler and is one of the most important non-surgical methods for facial rejuvenation and contour change. Objectively speaking, there are always pros and cons to things. Due to individual differences (e.g. easy bleeding, allergies, etc.) or the varying standards of doctors, local unevenness, redness and swelling after hyaluronic acid injections may also occur occasionally, causing pain to the candidates. But don’t worry, there is a regret medicine available for hyaluronic acid injection, which is hyaluronidase. Hyaluronidase is a catalyst that can accelerate the metabolism of hyaluronic acid at a rate of tens of thousands of times, which means that hyaluronic acid that normally takes 1 year to disappear after metabolizing in the body can theoretically be completely metabolized in a few minutes after being catalyzed by hyaluronidase. There are several other issues that need to be explained to you before applying hyaluronidase to dissolve hyaluronic acid: 1. Since hyaluronidase is extracted from animal testes, it should be tested for sensitivity before use. 2. The maximum metabolism time of hyaluronidase in the body is 2 weeks, so it is necessary to inject hyaluronic acid again at least 2 weeks later to ensure that the newly injected hyaluronic acid is not dissolved. 3.Since hyaluronic acid will fuse with tissues 1 month after injection, the amount of hyaluronidase is on the high side when dissolving the old hyaluronic acid in order to have an effect. 4.While dissolving exogenous hyaluronic acid, hyaluronic acid in the autologous skin will also be dissolved, but don’t worry, the body’s own hyaluronic acid metabolic cycle is 24 to 48 hours, so the loss of its own hyaluronic acid caused by hyaluronidase will be fully recovered within 48 hours, at the latest within 2 weeks. The use of hyaluronidase requires the doctor to have rich clinical experience, and how to dissolve the injected hyaluronic acid efficiently and appropriately is a highly technical job, in which the fine adjustment of the bump is more important to the doctor’s professionalism.
