PDO Threads are absorbable Polydioxanone (PDO) sutures that have been used in surgical procedures for over 30 years. They are frequently used in cardiothoracic, trauma, and gynecological surgeries. PDO is a FDA approved suture material for tissue approximation for the entire body. The suture material is broken down over 4-6 months via hydrolysis and stimulates collagen production in the skin due to the body’s natural healing process. It works like many other aesthetic treatments by creating a “controlled damage zone,” in the affected area.
There are 4 types of PDO threads:
- Smooth threads are used to create structure through a mesh technique. These tend to be 29 gauge (the higher the gauge number the smaller the thread diameter, just like needles) or 31 gauge. We create a sort of “basket weave” effect to give the skin a more structured, tightened, and smooth appearance. This technique combats crepiness and results appear approximately 4-6 weeks post treatment.
- Twist threads are used to produce a more voluminous appearance. These are used in the lips and in deeper lines like the nasolabial folds and marionette lines adjacent to the corners of the mouth. Results appear immediately and get better over time.
- Barbed threads create the most dramatic effect. The sutures have tiny barbs that provide a gripping effect in the tissue. Appropriate planning and placement followed by tensioning of the thread provides a dramatic and immediate lifting effect to the facial skin. Results can last approximately 12 months.
- Infinity Threads, or molded PDO threads are the newest and most innovative products in the non-surgical lift category. The dual-angle cut of the Barb5 is created to be slightly shallower allowing a thicker thread with increased tensile strength, resulting in the use of less threads to achieve optimal results.
