Mono threads are single, smooth threads composed of a material called PDO, polydioxanone. PDO is an absorbable polymer that has been used for many years as suture material in surgical (including cardiac) procedures and wound closure. PDO threads are absorbed by hydrolysis over a 6-month period. Mono threads most be anchored to a point on the face.
