Autologous fat augmentation of the eyebrow arch is the best alternative to prosthesis and biologics in recent years. Autologous fat is completely taken from our own tissues, which makes the surgery safer and does not cause any adverse reactions caused by the material after the surgery. It can guarantee the activity of fat cells to the greatest extent and effectively guarantee the survival rate of fat transplantation. After the surgery, the eyebrows have a natural shape, smooth lines, minimally invasive and scarless, and recovery is fast. However, since fat has a certain absorption rate, it usually requires about 2 injections. In addition, for those who need a particularly clear sense of arch contour, the effect is not as good as that of prosthesis. Autologous active fat transplantation is used to extract fat particles from fatty areas of the body and extract highly active fat cells through purification, and then inject them into the flat and sunken arch area in layers through precise injection techniques, thus making the arch area clear and three-dimensional, and achieving a lasting effect of eyebrow augmentation. Complications such as pain, edema, bruising, hematoma and infection may occur in the early postoperative period, i.e. 1-7 days after surgery, and pigmentation, too much or not enough grafting, and nodules in the grafted area may occur 1-3 months after surgery. Excessive amount of fat or over-concentration of fat injection and large amount of fat accumulation will lead to fat necrosis, dissolution and absorption due to insufficient blood supply, which will easily lead to infection and sequelae such as fibrosis or calcification and fat necrosis. Also, special attention should be paid to the possibility of fat embolism during fat grafting, which can cause sudden blindness, shock or hemiplegia, or even death. However, as long as the procedure is done strictly and skillfully, complications rarely occur.
