PDO, PCL and cog structure — how to choose a thread

01Choosing Between PDO and PCL Threads

When deciding on a thread lift, many patients inquire about the differences between PDO (Polydioxanone) and PCL (Polycaprolactone). Both materials are biocompatible and absorbable, but they differ in their absorption times and how long their effects last.

PDO is the material used in the Pailin cog thread. The polydioxanone is absorbed by the body over roughly 6 to 8 months.

It is worth being precise about where the lift comes from, because this is the most common misunderstanding. The change you see immediately after the procedure is mechanical — the barbs along the thread engage the tissue and hold it in position.

Collagen forms around the thread over the following weeks. That is a separate, later effect, and it is not what produces the lift on day one.

PCL is the material used in the Tourmaline cog thread. Polycaprolactone is absorbed over roughly 24 to 36 months — considerably slower than PDO.

A slower-absorbing material does not automatically mean a longer-lasting result. How long the material takes to disappear is a property of the polymer; how long the visible lift holds is assessed by the physician for each patient and depends on tissue quality and how many threads were placed.

The two are routinely conflated and they are not the same number. Each programme states its own expected duration — the Onyx V-Shape programme, for instance, is typically maintained for 12 to 18 months.

02Considering Gauge and Barb Structure

Another critical factor in choosing the right thread is its gauge (thickness) and barb structure. The Grand Diamond Thread Lift uses a range of gauges and barb structures tailored to different areas of the face — thicker threads where more pronounced lifting is needed, finer threads for subtle adjustment.

Which material a given programme uses is confirmed with you at consultation.

The Onyx V-Shape Thread Lift uses cog threads placed to contour the lower jawline and define a V-shape silhouette. These threads typically feature barbs that anchor into the skin to provide stable support for reshaping the chin and jaw contours.

The physician will determine the appropriate gauge and structure based on your individual needs during consultation.

03Understanding Treatment Options

The Grand Diamond Thread Lift is our comprehensive facial lifting procedure, designed to address multiple areas including the temples, cheekbones, jawline, and neck. This treatment involves customizing threads according to your unique bone structure to achieve a natural-looking lift without over-tightening.

The session duration ranges from 60 to 90 minutes, with minimal recovery time—mild bruising may persist for up to three days.

The Onyx V-Shape Thread Lift focuses on reshaping the lower jawline and enhancing the chin angle. Placing threads strategically along the jawline helps create a more defined V-shape contour.

The treatment lasts approximately 45 minutes with no or minimal downtime, making it a convenient option for those seeking subtle improvements.

For patients looking to maintain a youthful appearance without dramatic changes, the Ruby No.5 Baby-Face is an excellent choice. This procedure combines single-thread hydration and subtle volumizing effects to restore softness and fullness to the skin.

The session takes around 45 minutes with no downtime required. It is the shortest-lasting of the thread programmes — typically 6 to 9 months — because mono threads resorb faster.

04Conclusion

Ultimately, the decision between PDO and PCL threads depends on your specific goals and preferences. Consultation with a physician at Waleerat Clinic will help determine which material, gauge, and barb structure is most suitable for you.

Remember that individual outcomes vary based on factors such as skin condition and lifestyle habits.
