The field of aesthetic medicine has witnessed significant advancements over the years, with PDO threads emerging as one of the key non-surgical options for skin rejuvenation. This article seeks to demystify the world of PDO threads, explaining what they are, how they function, and the various types available in the market.

Introduction: What Are PDO Threads?

The term ‘PDO thread’ stands for Polydioxanone thread. PDO threads are synthetic absorbable surgical sutures that are widely accepted for their safety in various medical procedures, such as suturing during surgeries. In the realm of cosmetic treatments, they have been repurposed for their capacity to lift, tighten, and rejuvenate the skin.

How Do PDO Threads Work?

Understanding how PDO threads work is crucial to appreciating their efficacy in aesthetic medicine. Once introduced into the skin, they provide an immediate lifting effect. But that’s just the beginning. As these threads get absorbed over time, they stimulate collagen production, a natural protein that keeps our skin supple and youthful. Thus, beyond their immediate effect, PDO threads encourage the body’s rejuvenating processes, leading to natural-looking results lasting several months to a year.

The Different Types of PDO Threads

While all PDO threads serve the primary purpose of rejuvenation and lift, there are different types, each tailored for specific needs and results.

Mono Threads: These are smooth threads without barbs. They are placed in a mesh-like pattern into the skin to provide a foundation for new collagen production. While they don’t give an immediate lift, they are excellent for general skin tightening over time.

Cog Threads: Characterized by barbs along the threads, these are designed to latch onto sagging skin to provide an immediate lift. The barbs form a support structure that lifts the sagging tissue. Over time, as the skin gradually produces collagen, the areas treated with cog threads benefit from additional tightening and rejuvenation.

Screw Threads: These consist of one or two intertwined threads, ideal for adding volume to the treated areas. Screw threads are often used to improve the look of the face’s recessed areas like the cheeks or under-eye area.

Mesh Threads: These threads create a net or mesh under the skin, which is a foundation for collagen production. They are ideal for areas that require subtle tightening without a pronounced lift.

What Is the Best Type of PDO Thread?

Determining the best type of PDO thread depends largely on the specific needs and goals of the individual. There’s no one-size-fits-all answer, as the different types of PDO threads are designed to address various concerns.

• Monofilament Threads: Best for those seeking subtle skin rejuvenation and collagen stimulation. Their smooth texture makes them ideal for areas that require gentle enhancement.
• Screw Threads: Suitable for individuals looking to add volume to certain areas of the face or body. The intertwined design provides a more substantial effect.
• Barbed Threads: Ideal for significant lifting and reshaping, particularly in areas with more pronounced sagging. The tiny barbs grab the tissue, allowing for a dramatic lifting effect.

The choice between these types of threads should be made in consultation with a qualified medical professional with expertise in PDO thread procedures. They will assess the individual’s skin type, areas of concern, and desired outcomes to recommend the most appropriate type of PDO thread.

Therefore, the best type of PDO thread is one that is aligned with the unique needs and expectations of the patient. The collaboration between patient and practitioner in understanding these factors ensures a successful and satisfying result.

What Is the Strongest PDO Thread?

In the context of PDO threads, the term “strongest” often refers to the ability of the thread to provide significant lifting or support. Barbed threads are typically considered the strongest among the different types of PDO threads.

Barbed threads are designed with tiny barbs or cogs that latch onto the underlying tissue. This unique design enables the threads to grip and lift the skin more effectively, making them particularly suitable for areas with substantial sagging or where a more pronounced lifting effect is desired.

The strength of the barbed threads is attributed to both the material’s inherent qualities and the way they are constructed. The barbs are strategically oriented to support the tissue in the desired direction, providing a firm hold and a lasting lifting effect.

However, it should be noted that the choice of the thread must be carefully matched with the patient’s specific needs and the area being treated, and professional consultation is essential to determine the most appropriate option.

What Are the Longest Lasting PDO Threads?

The longevity of PDO threads depends on various factors, including the type of thread used, the area treated, and the individual’s skin condition. Certain characteristics may contribute to longer-lasting effects among the different types of PDO threads.

• Barbed Threads: Often considered to provide the longest-lasting results, barbed threads are designed to grip the tissue firmly. Depending on individual factors, this allows for a more noticeable lifting effect, lasting anywhere from 12 to 18 months.
• Screw Threads: While screw threads may not last as long as barbed threads, their unique design does provide volume, and the effects can be seen for around 9 to 12 months.
• Monofilament Threads: Monofilament threads generally have the shortest duration, with effects lasting between 6 to 9 months.

It’s essential to note that the longevity of PDO threads also relies on the skill of the practitioner and the quality of the threads used. Proper aftercare and maintenance, such as following a good skincare routine and avoiding excessive sun exposure, can also contribute to longer-lasting results.

While barbed threads are often considered the longest-lasting type of PDO threads, the specific duration may vary widely depending on individual circumstances, practitioner skill, and the quality of the materials used. 

Advantages of Using PDO Threads

Beyond their primary function, PDO threads offer several advantages:

Minimally Invasive: PDO thread treatments require no extensive cuts, unlike surgical facelifts. Small needles are used to introduce the threads, reducing recovery time and potential complications.

Short Treatment Time: A typical session may last between 30 minutes to an hour, making it possible to undergo the procedure even during a lunch break.

Natural Results: Since PDO threads stimulate the body’s collagen production, the results look and feel natural.

Dissolvable and Safe: Being made of Polydioxanone, the threads are safely absorbed by the body over time, leaving no foreign material behind.

Risks and Considerations

Before opting for PDO thread treatment, it’s essential to consider potential risks, such as:

• Infection
• Bruising or swelling
• Thread migration or breakage
• Mild discomfort

Consulting with a qualified medical professional experienced in PDO thread procedures can mitigate these risks.

Conclusion

PDO threads represent a remarkable convergence of surgical wisdom with aesthetic ambition. They offer a non-invasive route to younger, firmer skin and are a testament to how far non-surgical aesthetic treatments have come. Whether you are a patient curious about the procedure or a practitioner looking to offer the latest skin rejuvenation, understanding the different types of PDO threads and their functions is crucial. As with any medical procedure, it’s essential to consult a certified professional to determine the best approach for individual needs.
