PCL fish bone cog threads are innovative sutures designed for lifting sagging skin and restoring younger faces, primarily using polycaprolactone (PCL) material, which means longer-lasting effects than PDO threads. Their unique fish bone structure enhances tissue lifting and provides optimal support, making them effective for contouring and tightening the skin. These threads offer long-lasting results while minimizing scarring. Diaminy PCL fish bone cog threads has outstanding shape and better lifting effects, which is our best-selling products among all face lifting threads.
