Understanding PDO Threads: Mechanism, Types, and Clinical Outcomes

A concise clinical overview of mono, screw, and cog PDO threads, including mechanism of action, lifting behavior, and practical treatment planning considerations.

How the treatment works

PDO threads are absorbable sutures placed in the subdermal plane to support soft tissue repositioning while stimulating fibroblast activity and collagen remodeling over time.

Clinical effect comes from two overlapping mechanisms: an immediate mechanical support effect after insertion, and a delayed biostimulatory response as the thread gradually hydrolyzes and the tissue remodels.

Thread selection should follow anatomy, skin quality, vector design, and patient expectation. Strong lifting indications require more than product knowledge alone; insertion depth and tension balance matter just as much.

Clinical planning

Better outcomes usually come from matching thread architecture to the treatment objective rather than overcorrecting with higher-tension placement.
