Silhouette InstaLift® sutures and suture cones are made from glycolide/L-lactide (PLGA), a polymer often used in medical devices and with a proven record of being well tolerated by the body’s systems. The sutures and cones, which are eventually absorbed into the body, work by lifting the internal skin and adding volume. The bi-directional cones also help hold the sutures and subdermal skin in their new elevated position.
