LIFSkin Cog is a PDO thread that tightens, lifts and smoothes wrinkles. Featuring 360-degree single barbs, this PDO filament incorporates a helical pattern twist around the thread, allowing precise insertion into the skin. The PDO thread uses a blunt 45°, W and L-type needle designed to minimise discomfort during the treatment. The package contains 10 x 19G (70mm) needle-type cog threads.
