Autologous lipofilling of the tear trough provides longer lasting results, gives fuller eyes and enhances the elasticity of the skin around the eyes. However, if not done properly, conditions such as fat embolization may occur. Autologous fat filling of tear trough is to inject fat from fat-rich parts of the body, such as abdomen, buttocks, thighs, etc. into the tear trough after liposuction and processing, so as to achieve the effect of filling the tear trough and increasing the three-dimensional sense of the face. Autologous fat is the best filler material, with high surgical safety and natural and beautiful postoperative results. After the surgery, the result is natural and beautiful. Moreover, the fat will be permanent and effective after survival, and the surgery is low in pain and does not leave any scar. However, if the fat is injected into blood vessels, it can cause fat embolism, which can cause local pain and swelling, and in severe cases, it can cause blindness. If the amount of fat filling is too much, it may also cause localized facial bulging, resulting in bilateral eye asymmetry. Therefore, it is recommended to go to the hospital for consultation and examination, and perform the surgery under the operation of professional doctors.
