PDO Screw (Twisted) Thread Series
PDO Screw (Twisted) Threads is a PDO smooth thread coiled around a needle for extra collagen stimulation boost and volume following each thread insertion. This will effectively increase the threads' contact area with a subcutaneous fat layer by adding more fibrous connective tissues to develop. PDO Screw Thread sutures for greater pushing up and volumizing of tissues compared with basic smooth (monofilament) threads. These threads are very popular due to their versatility and ability to support tissues while increasing collagen volume in deficit tissues.
In combination, PDO screw (twisted) thread sutures are used to support tissues and can be placed in a mesh pattern to reinforce barbed (cog) thread placement while enhancing the overall effect of treatment. The main advantage of using screw PDO threads is it reduces the amount of smooth (monofilament-type) needed for differing aesthetic applications.
PDO screw (twisted) thread sutures are to be placed into the subcutaneous fat layer of the skin to promote the production of collagenous connective tissues around the inserted threads.

PDO Glossary of Terms
What are PDO threads?
PDO, or polydioxanone, is a biocompatible product commonly used in surgery as an absorbable suture. PDO are not permanent when placed under the skin and will be reabsorbed over about 4 to 8 months. PDO sutures eventually are broken down in the body ultimately ending up as water and carbon dioxide.
There are two (2) basic types of PDO threads – monos (smooth threads) and cogs (barbed sutures).
Monofilament threads (monos or smooth threads) are thin lengths of PDO that are preloaded onto a thin needle which are inserted into the skin. The needle can hold single flat threads, threads wound in a spiral (screw, twisted, tornado) or multiple threads braided together (mesh). The more PDO material in the thread, the more collagenesis is created and biostimulation expected. Mono threads are usually completely absorbed within 4-6 months.
Cog (barbed) threads are thicker lengths of PDO that are loaded onto a cannula which is then inserted into the skin. These threads have little cogs or barbs which will engage the skin and can lift up sagging skin in different areas of the face and body (cheek, jowl, arms, knees, or brow etc.) when the thread is pulled upwards. As they are stronger than mono threads, cogs (barbed threads) can obtain more lifting and contouring. Cog threads are also fully absorbed between 6-9 months.
How do PDO Threads work?
PDO, or polydioxanone, has been shown to stimulate new collagen within the skin. The newer technologies utilizing free floating (no fixation points) PDO Threads allows for much less risk of complications such as scars and nodules that are seen with the older threads that were either permanent or fixed under the skin.
Common treatments such as lasers, peels, RF, or even PRP treatments, cause a wound healing response and a stimulus for new collagen at one point in time. In contrast, PDO threads have an advantage as they can stimulate collagen over a longer period of time (at least 12-18 months).
What can PDO threads do for patients?
A PDO thread lift treatment can help improve skin quality (smooths and rejuvenates), create tissue integrity, and tighten sagging skin on the face, neck and body (arms, abdomen and buttocks). Depending on the indication to be corrected you will use monos (smooth threads), cogs (barbed threads) or combinations of threads.
As a general rule, mono (smooth) threads are suitable for younger patients who are not yet experiencing sagging skin, loss of skin volume, and want to maintain their skin quality. Mono (smooth) threads may help tighten the skin in some areas or to prepare the skin to receive cog threads in the future.
Cog (barbed) threads are generally suitable once there are signs of sagging skin, such as the cheeks or chin area and typically for patients in their 30s onwards. All types of PDO Threads stimulate collagen under the skin where they are placed including the Mono (smooth) or COG (barbed) threads.
Which anatomical areas are most requested by patients concerning thread lift procedures?
The face is the most popular and requested area for treatment. Most patients request lifting around the jawline since the aging process in the face tends to accumulate additional fat around this area and we lose that youthful “V-Shape” to the face. By the age of 40+ the effects of gravity start showing within the face as fat in the cheeks will descend resulting in a flatter, upper part of the face.
Eyebrows are also very popular as well with females as they prefer that the eyebrow be at least 1cm above. Most patients want to fix their eyebrows because they are lower than the desired look. Similarly, as we grow older, it is one of the first noticeable parts of the face that begins to sag and lower. Even as you reach 30+ years of age, your lateral eyebrows will already start to droop and who opt to lift their eyebrows.
Other facial areas for threads include the neck area as well as narrowing the tip of the nose and correct the tip of the nose creating a high nose bridge. It is a 30-minute procedure with zero downtime and very good results.
Which is contraindicated concerning thread lift procedures?
There are both relative and absolute contraindications for the thread lift procedures, though the following illustration may seem like there are many contraindications it is very safe in most of your patients:
Treatments
PDO (Polydioxanone) threads generally last about 6-8 months for its full biodegradation after insertion and upon insertion stimulates collagen production during that period of time. The result from this collagen stimulation may last up to 12-24 months depending upon the patient and indication corrected.
Topical anesthesia is strongly recommended for patient comfort during the treatment. Swelling and edema may last 3-5 days after treatment and transient bruising may occur but varies and is different for each patient, technique, and treatment indication.
Popular Indications for Facial and Body Treatments
- Eye Hollows (Tear Trough)
- Acne Scarring (remodeling)
- Lateral Canthal Rhytids
- Enhanced Vermillion Border
- Jawline Folds or Depressions
- Infraorbital Rhytids
- Smoker Lines (Perioral Area)
- Malar Cheek Augmentation
