What are PDO Threads?

Updated: Jun 21, 2022

PDO threads are threads made from a colourless polyester that breaks down in your body after about 6 months, and are one of the three types of sutures commonly used in thread lift procedures. PDO threads have been in use for surgeries since the 1980s and have lasted the test of time.

The presence of these sutures in your skin triggers cells in your body called fibroblasts to produce more collagen. Collagen is the protein that gives your skin its shape and elasticity. Loss of collagen over time is one of the main causes of aging skin, and restoration of collagen will revert these changes.


PDO threads can be further divided into these three categories:

  • Mono threads. Smooth sutures that help rejuvenate your skin by stimulating collagen production.

  • Screw threads. Made up of one or two intertwined threads, these are used to help restore volume to sunken parts of your skin. These are useful for lifting procedures.

  • Cog threads. These threads have barbs that latch into your skin like small fishhooks, to provide support and lift parts of your face. Good for lifting procedures.


PDO thread lifts have a significantly lower risk than surgical procedures and facelifts. There’s less risk of bruising, scarring, or bleeding when performed by a trained professional. Minor complications happen in about 15 to 20 percent of procedures but are usually easily corrected.
