Reading Time: <1 minute Petit cosmetic surgery using hyaluronic acid is becoming more common. Easy, quick, painless transformation... In fact, rhinoplasty, tear bag surgery, lip surgery, and chin surgery using hyaluronic acid are widely performed and many patients are satisfied with them. This is one of the reasons why cosmetic medicine has become more commonplace compared to the past when only cosmetic surgery was available. However, if a doctor who has not thoroughly studied basic anatomy such as the course of blood vessels and the properties of hyaluronic acid suddenly becomes the director of a cosmetic surgery clinic and performs treatments on many patients, there will be cases where risks cannot be avoided. It is common sense to understand the course of arteries, but in the case of a procedure such as injecting hyaluronic acid anywhere without understanding it, there is a high risk of necrosis of the area controlled by the nutrient blood vessels due to arterial embolism, and if the nutrient blood vessels to the optic nerve are embolized, the worst case scenario of blindness will occur. In fact, there have been reported cases of blindness in cases of petit cosmetic surgery using hyaluronic acid both overseas and domestically. Most of these cases are due to the doctor's lack of experience as a cosmetic surgeon and sloppy treatment when they are busy. Although petit cosmetic surgery is simple and brings great benefits, we recommend that you have the procedure performed by a cosmetic surgeon with a wealth of experience who can perform the procedure carefully and carefully.
