PDO (polydioxanone) threads are dissolvable sutures used to create a nonsurgical PDO thread lift or stimulate your body's natural collagen production. These sutures, used for decades in surgeries, have made their way into the aesthetics field... and rightfully so. When strategically placed, the face can be lifted and held in placed by the sutures. While the sutures are dissolving, the body's repair response is triggered and generating new collagen and elastin around the thread to act as scaffolding once the sutures are dissolved.
