When people think of ways to correct tear troughs, they often think of surgery, autologous fat or hyaluronic acid fillers. However, with advances in surgical techniques and material science, a new treatment for tear troughs has been created! That’s the threaded filler method! In short, a special medical wire is embedded in the sunken area of the tear trough, exchanging the “flesh and blood” of the wire for the rejuvenation of your face. Before starting the procedure, the doctor will first mark the area of the tear trough, as well as the location and direction of the wires. After your face is sterilized, a local anesthetic is injected into the area where the threads are placed. This is the only time you will feel any pain, and then the procedure and recovery afterward will be easy and enjoyable! The principle of the action of burying the thread to fill the tear trough is that, on the one hand, the volume of the wire itself has a physical filling effect, on the other hand, in the process of degradation of the wire, it can stimulate the proliferation of collagen fibers and elastic fibers of the surrounding tissues, and indirectly play a filling effect. Under these two mechanisms of action, the theoretical maintenance time up to about 2 years.
