The collagen production from inserting PDO threads starts almost immediately and provides an instant lift. The threads fully absorb after 6-12 months. As the threads naturally resorb into biological fluids, they stimulate the production of procollagen molecules and induces reactive fibrosis (creates collagen). This process maintains the lifting outcomes beyond their resorption. Dermal fillers are an adjunctive procedure to PDO threading.  PDO threads create a slimmer facial effect, cellular renewal and tighter firmer skin.
