With age, our face begins to descend and the oval of the face begins to deteriorate. PDO (polydiaxanone) threads are often used to reverse this effect. These threads are made of the same material as the threads used in surgery and have fine notches on them. These are placed under the skin with special apparatus called cannula. The ends of the threads are pulled upwards and the suspending is done upwards on the skin. While the threads placed under the skin are melted by the body within months, the suspension period created on the skin lasts up to 1 year. Although the melting time of some threads is much longer, the suspension times on the leather are the same as PDO threads. The application time is about 15-20 minutes. When local anesthesia is applied before the application, the feeling of pain is low.
