PDO Thread Lift also known as the "lunch time face-lift" can be done in as little as an hour. Using micro-fine needles, tiny threads are inserted into the skin to form a mesh that stimulates collagen production. The threads are made from an absorbable compound called Polydioxanone (PDO) that dissolves around six months, leaving a path of collagen in its place. PDO Threads are excellent for sagging neck, jowls, cheek enhancement, and mid face lift.
