Tear trough lines are usually not harmful to the body and there is usually no need to remove them. If you feel that the tear trough lines affect your beauty, you can take local injection of hyaluronic acid and autologous fat transplantation as prescribed by your doctor to remove them. 1. Hyaluronic acid injection: local injection of hyaluronic acid can fill the skin, so that the skin in the tear trough area can be lifted, tightened and flattened. 2. Autologous fat transplantation: Autologous fat transplantation can be performed according to the doctor’s prescription, where fat is extracted from other parts of the body and filled into the tear trough area to flatten the sunken tear troughs, thus removing the tear trough lines. It is recommended that patients who want to remove tear trough lines go to a regular hospital and choose the appropriate treatment under the guidance of a professional doctor.
