seven different types of Intraline PDO Threads

The world of cosmetic surgery is constantly advancing and industry innovation is making it easier than ever for patients to improve their appearance without having to go under the knife. While surgical procedures were once the only way to lift and tighten the face, alternatives like Botox and Intraline PDO Threads are now a leading pain-free non-surgical option for face lifting.

What Are PDO Threads?

PDO Threads are threads made of polydioxanone that lift and tighten tired and aging skin tissues. This cosmetic technique not only provides visible improvement to the skin with immediate lifting effects, but also improves the skin network over time by stimulating collagen production.

During this cosmetic procedure, PDO threads are implanted into the subcutaneous tissue in the face, creating a vectorial network that offers increased support to the skin. While there are some visible effects immediately following the 30 to 90 minute procedure, optimal results will not be seen until six months after. This is due to enzymatic absorption, where the threads are absorbed by the skin and leave newly produced collagen in their place. In addition to being li fted, the patient’s skin will feel healthier after the procedure and the skin will look brighter, more elastic, and fully rejuvenated. Results last on average for one to two years.

Intraline PDO Threads come in Mono, Spiral, Triple, and Cog Dimension 360 packaging. Intraline guarantees that each product has:

  • CE-certified PDO that is safe to use
  • Quality auditing to ensure high manufacturing production standards
  • Specially designed needles and stoppers to enable accurate insertion and thread stability
  • High-quality threads that provide excellent dermal traction and long-lasting results
  • Correct thread temperature storage to prevent snapping


Intraline Mono Threads contain the smallest gauge needle in their product line. It features a simple filament that contains no twist or barbs. They are the most basic, but also the most common, thread treatment for lifting.


Intraline Spiral Threads, or screw type, are similar to the Mono line. However, Spiral Threads also have a filament wound around the needle or cannula. The filament helps produce greater amounts of collagen, though this thread type is similar in size to the Mono line.


Intraline Triple Threads remain small but produce more collagen growth and skin rejuvenating stimulation. They have increased lifting and holding capabilities compared to the Mono and Spiral lines. Made of three PDO filaments twisted together and held in place by a unique stopper, they are smaller than the Cog Threads. 

Cog Dimension 360

Intraline Cog Dimension 360 Threads are the premiere line of threads. They are the strongest of the Intraline Thread products and provide maximum hold. It contains a filament that is barbed in a spiral shape, giving maximum traction upon implantation. This design results in increased lifting and hold over the other thread lines.

What is Polydioxanone (PDO)?

Polydioxane is a material that has been used in the medical field for many years. It is extremely safe and is often used during heart surgery to encourage cell cohesion. PDO is a sterile thread that is absorbed by the skin and produces fibrosis in the implantation area. This gives rise to the creation of new type I and II collagen. PDO is produced through a process of polymerization of p-dioxanone. Polydioxane does not cause any allergic reactions, is well tolerated by the skin, and does not results in any adverse effects.

What is PDO Thread Treatment?

During treatment, threads are implanted just under the skin, where the PDO is able to help the body produce its own stores of collagen, elastin, and hyaluronic acid, which the skin loses as it ages. In addition to leaving the skin firmer, PDO Threads improve overall quality, brightness, and smoothness by stimulating new blood vessel development and improving lymphatic drainage. The results of PDO Thread Treatment are two-fold: the initial lifting and tightening produced by implantation, and the secondary stimulation of important nutrients within the skin.

Collagen, elastin, and hyaluronic acid are all necessary substances for keeping the skin firm and smooth. Collagen creates tension and firmness, which lifts the skin tissue and tightens the surface, reducing lies and wrinkles. Elastin increases elasticity, bringing a youthful suppleness to the skin. Hyaluronic acid provides and retains moisture, increasing hydration and creating healthy plumpness. When all these forces work together, it produces an overall effect of younger, healthier, rejuvenated skin.

There are several different Intraline PDO Threads, each with their own treatment. Each Intraline Thread is made of the highest quality PDO manufactured with strict standards. The treatment style is determined by trained practitioners who assess each individual patient’s concerns.

How to Get Trained in PDO Thread Treatment

Intraline offers their own PDO Thread training courses based on their white paper study that featured 40 patients observed over a 12-month period. In the course, clinicians are taught safe and effective PDO Thread treatment techniques, enabling them to provide patients with optimal results. Highly trained clinicians teach a three-stage process that covers the theory, practicality, and safety behind effective Intraline PDO Thread treatment.


Patients no longer must undergo intense and painful surgical procedures to achieve firmer, more youthful looking skin. Intraline’s thread lines are made of safe and effective polydioxanone that not only lift the skin upon implantation but stimulates the production of key nutrients upon absorption. This dual process ensures that healthier skin starts on a cellular level, leaving the patient looking and feeling great.
