Polyoxidanon and polylactic acid threads, which are used in the process of facial rejuvenation with thread hanger, melt over time. Therefore, the effect of the procedure is not permanent. However, polyoxidanone and polylactic acid threads have the feature of renewing and strengthening the skin. As it melts, it activates the collagen bonds in the area where it is located. Therefore, after the threads melt, the skin continues to renew itself for a while and maintain its tight structure. After the facial rejuvenation application with a thread lift, the skin has a bright, youthful and flexible appearance for a long time. The melting time of the threads varies according to the application area and the skin structure of the person. If the application is made to the moving areas where the use of mimics is common, the permanence period may be a little short. Generally speaking; We can say that the effect of facial rejuvenation with a rope hanger continues for 1-2 years. This period may be even longer in some people, as the effect continues after the hangers melt.
