What are PDO threads?

PDO threads, also known as a Polydioxanone thread lift is simply a procedure that uses a dissolvable suture to lift and tighten the skin. Typically, PDO threads can be performed within just 45 minutes and are a lot less invasive than a traditional facelift which requires surgery.

PDO thread lifts are designed using a unique biodegradable polyester suture, which eventually is broken-down by the skin. It is important to understand that there are different types of PDO threads, and whilst some are best suited to rejuvenating the skin, some are specifically designed to lift sagging skin. 

What are PDO Threads used for?

Made of Polydioxanone, PDO threads are one of three types of sutures commonly used in thread lift procedures. The other two types are PLA, made from polylactic acid and PCA made from polycaprolactone.

Out of the three, PDO threads have been around the longest. PDO threads have actually been used by surgeons in surgery since the 1980s. 

The materials used in PDO threads are naturally broken down by the body in around 6 months. Made from a colourless polyester, PDO threads used within the skin, trigger fibroblasts to encourage collagen production. Collagen is a naturally occurring protein found within the body that allows the skin to retain its structure and elasticity. 

There are three different types of PDO threads, and each one is designed specifically for its intended purpose. The three types are:

PDO cog threads – small barbs, like fishhooks are designed to latch the skin and provide significant hold and lift to the face. 

PDO screw threads – used to restore volume to sunken areas of the face, screw threads are made up of one, or two intertwined threads.

PDO mono threads – smooth sutures designed to rejuvenate the skin and stimulate collagen production.

When deciding which PDO thread is best for your patient, you should always analyse the skin, and the patients’ individual concerns before selecting a thread. The type of PDO thread you select will be determined by the desired outcome. 

Where can PDO Threads be used?

As the procedure is non-invasive, PDO thread lifts can be used to treat most areas of the face that are showing signs of ageing, including:

  • Eyes
  • Cheeks
  • Neck 
  • Jaw
  • Neck 

The results of PDO thread lifts are not as drastic as that of a surgical facelift, therefore they work effectively alongside other antiaging procedures such as dermal fillers.
