Hyaluronic acid is an inherent component of human skin. Its function is to retain water, moisturize, and maintain skin hydration. There is no harm in itself. However, in clinical work, patients who seek treatment after injection of hyaluronic acid are often encountered. The main reasons are as follows: 1. Vascular embolism, the most serious complication of hyaluronic acid injection is vascular embolism. The principle is that in the process of injecting hyaluronic acid, it is accidentally injected into a blood vessel. If it is injected into a small blood vessel, the skin of the blood supply site will gradually turn black, and the patient will Feeling pain, if injected into a large blood vessel, the consequences will be more serious, such as the ophthalmic artery, the patient will be blinded immediately; 2. Infection, although the needle hole for hyaluronic acid injection is very thin, it is possible for bacteria and viruses to pass through the needle hole to the subcutaneous, if the patient is resistant At lower levels, bacteria and viruses can gradually spread at the injection site and, if accidentally entered into the bloodstream, can cause a systemic infection.
