PDO (Polydioxanone) threads are one of the most popular options for non-surgical facelifts and skin rejuvenation. These threads can deliver impressive results by tightening, lifting, and contouring the skin through collagen stimulation. However, not all PDO threads are created equal—each type serves a unique purpose and is designed for specific aesthetic needs. In this article, we’ll explore the different types of PDO threads available and help you understand which might be the best option for your treatment goals.
What Are PDO Threads?
PDO threads are made from a biodegradable polymer known as polydioxanone, which is widely used in surgical sutures due to its safety and biocompatibility. When PDO threads are inserted into the skin, they act as a support structure, encouraging collagen production as they gradually dissolve over 6 to 12 months. This process leaves a new matrix of collagen and elastin in the treated area, providing a lasting lift and skin improvement that can persist for up to 18 months or more.
Types of PDO Threads
Understanding the types of PDO threads and their specific applications is essential for achieving optimal results. Each type of thread is designed for a unique purpose, offering targeted benefits for lifting, volumizing, and rejuvenating various areas of the face and neck.
1. Mono Threads
Ideal for Skin Rejuvenation and Firming
Mono threads are smooth threads without barbs and are used primarily for skin rejuvenation rather than lifting. They are typically inserted into the skin in a mesh pattern, where they stimulate collagen production and enhance skin firmness over time.
Applications:
- Face, neck, and under-eye areas.
- Suitable for patients with mild skin laxity looking to improve texture and elasticity without a significant lift.
Benefits: Mono threads are a great option for people who want subtle, natural-looking improvements in skin firmness and smoothness. The increased collagen production helps to firm and revitalize the skin, giving a more youthful appearance.
2. Cog Threads
Ideal for Lifting and Contouring
Cog threads are similar to mono threads but are equipped with barbs or “cogs” that latch onto skin tissue, creating a lifting effect. These threads are excellent for patients looking to address sagging skin or to enhance facial contours.
Applications:
- Cheeks, jawline, and jowls.
- Commonly used to lift sagging skin in the mid-face and lower face.
Benefits: Cog threads provide a noticeable lift that can mimic the effects of a facelift, with the added benefit of collagen stimulation. This lifting effect is immediate and continues to improve over the following months as collagen production increases.
3. Screw Threads
Ideal for Adding Volume
Screw threads are designed to add volume and are an excellent choice for areas of the face that appear sunken or hollow. These threads are created by twisting one or more threads together, forming a screw shape that gives a fuller look.
Applications:
- Mid-face, nasolabial folds, and under-eye area.
- Useful for patients needing volume restoration and skin elasticity enhancement.
Benefits: Screw threads provide a subtle lift and are particularly beneficial for volume-deficient areas. They add fullness while also stimulating collagen, which results in firmer and plumper skin.
4. Tornado Threads
Ideal for Lifting and Adding Volume
Tornado threads, also known as “multi-screw threads,” consist of two intertwined threads that offer both volume and lifting effects. These threads are stronger than traditional mono or screw threads and provide more support.
Applications:
- Cheeks, jawline, and neck.
- Perfect for patients looking for a combination of lifting and volumizing effects.
Benefits: Tornado threads are versatile and can provide both structural support and added fullness. They are particularly effective in areas with moderate skin laxity, delivering a more lifted and rejuvenated look.
5. Double Screw Threads
Ideal for Enhanced Volume and Structure
Double screw threads are composed of two threads twisted around each other, giving them a thicker, stronger structure. These threads provide an enhanced volumizing effect, which makes them ideal for areas that need extra fullness and support.
Applications:
- Cheeks and temples.
- Suitable for patients with significant volume loss or for enhancing facial contours.
Benefits: These threads provide a noticeable boost in volume and are ideal for filling sunken areas. Double screw threads offer a unique combination of lifting, filling, and collagen stimulation for a comprehensive aesthetic improvement.
6. Barbed Threads (Molding Threads)
Ideal for Maximum Lifting Effect
Barbed threads, also known as molding threads, have the strongest lifting capabilities due to their advanced barbed design. Unlike cog threads, barbed threads are shaped to mold and hold tissues securely, providing an immediate and long-lasting lifting effect.
Applications:
- Cheeks, jawline, neck, and other areas needing significant lift.
- Popular among patients seeking a non-surgical facelift or noticeable lifting results.
Benefits: Barbed threads offer the most dramatic results among PDO threads, providing a robust and lasting lift that improves over time with collagen stimulation. These threads are ideal for people who want visible facial contouring and lifting without surgery.
How to Choose the Right PDO Thread
The choice of PDO thread type depends on various factors, including your skin’s needs, the area being treated, and your aesthetic goals. Here’s a quick guide:
- For Mild Skin Laxity and Rejuvenation: Mono threads are a great starting point, providing subtle firmness and texture improvements.
- For Sagging Skin and Lift: Cog threads or barbed threads are best for those who need lifting and contouring.
- For Volume Enhancement: Screw, tornado, and double screw threads work well in areas needing more fullness, such as cheeks and nasolabial folds.
- For Comprehensive Lifting and Volume: Combination treatments with various threads may deliver the best results, allowing for a tailored approach to each individual’s facial structure and skin condition.
Final Thoughts
PDO threads are a fantastic non-surgical option for anyone seeking skin rejuvenation, lifting, and contouring without the downtime of a traditional facelift. By choosing the right type of PDO thread—or a combination of them—you can achieve a youthful, rejuvenated appearance that lasts.
If you’re interested in PDO thread treatments, consulting with a qualified professional will help ensure that you receive the most effective type of thread and application for your unique needs. Whether you’re looking for subtle skin rejuvenation or a significant lift, PDO threads can be tailored to help you reach your beauty goals.
