Rejuvenation vs Cog PDO Threads: Key Differences & When to Use Each
Meta Description
Learn the difference between rejuvenation PDO threads and cog threads, when to use each, and how they impact lifting, skin quality, and treatment outcomes.
Introduction
PDO thread treatments continue to grow in popularity as more practitioners adopt the technology worldwide. However, with so many thread types available, it can be difficult to know which to use—and when.
At a high level, PDO thread treatments fall into two main categories: Rejuvenation Threads and Lifting Threads (Cog Threads). Understanding the difference between the two is key to achieving the right outcome for your patient.
Rejuvenation PDO Threads: Improving Skin Quality
Rejuvenation PDO threads are designed to enhance overall skin quality rather than create dramatic lift. They stimulate collagen production, improve circulation, and support tissue quality over time, resulting in firmer, more hydrated skin.
Types of Rejuvenation Threads
Mono, Double, Triple, Spiral (Screw), and Double Spiral threads each offer different levels of support and volumization.
When to Use Rejuvenation Threads
Ideal for improving texture, mild laxity, and early aging in areas such as the jawline, neck, and under-eye area. Typically 10–20 threads are used per treatment area.
Cog PDO Threads: Creating Lift and Structure
Cog threads are designed for lifting. Their barbs anchor into tissue, allowing repositioning and immediate lift.
How Cog Threads Work
They provide an immediate mechanical lift and longer-term collagen stimulation as the thread dissolves.
When to Use Cog Threads
Used for lifting cheeks, jawline, neck, and for non-surgical rhinoplasty. Typically 1–5 threads per area.
Intraline Cog Thread Technology
Intraline offers Dimension 360 and Dimension 720 threads. The 720 uses molded technology for improved strength and structural integrity.
Choosing the Right Approach
Rejuvenation threads improve skin quality while cog threads lift tissue. Often, both are used together for optimal results.
Final Thoughts
Understanding the differences between thread types allows practitioners to deliver more predictable and natural-looking outcomes.
