Tear troughs can be filled by hyaluronic acid injection, combined eye bag surgery, and autologous fat grafting. 1. Hyaluronic acid injection: If the patient’s tear trough is mild, it can be filled by injecting hyaluronic acid under the guidance of the doctor. 2. Combined eye bag surgery: If the patient’s tear trough is moderate or severe, the tear trough can be filled by combined eye bag surgery under the doctor’s guidance, in which the appropriate amount of orbital septum fat will be released through the internal and external approaches, and fixed in the area of the tear trough to improve the appearance. 3. Autologous Fat Transfer: Fat is extracted from fatty areas of our body, purified and injected into the tear trough area to fill it. Patients who want to fill the tear trough should go to a regular hospital to choose a professional doctor to fill the tear trough, and choose the right filling method for themselves under the doctor’s guidance, as any method of filling the tear trough involves risks and should be considered carefully.
