PDO thread lifts use absorbable polydioxanone sutures to mechanically elevate sagging tissue and stimulate collagen remodeling. Placed subdermally or in the subcutaneous plane via needle or cannula, the barbed or smooth threads anchor to deeper fascia, creating immediate lift. Over 6–12 months, the sutures dissolve while triggering a foreign-body inflammatory response that promotes fibroblast activity and neocollagenesis. The result is a combination of mechanical support and biological remodeling—though the mechanical component fades as the threads absorb.
