Auro PCL Fish Bone Cog Thread

The Fish Bone Cog Thread features a bidirectional barb structure that anchors into tissue immediately upon insertion, delivering mechanical lifting while simultaneously stimulating collagen regeneration — so results build over time.

Where It's Used and amp

• Common treatment areas: Mid-face (sagging cheeks), nasolabial folds, marionette lines, jawline laxity, drooping mouth corners, mild neck sagging.
  
• Expected results: Visible contour lift immediately post-treatment; progressive collagen renewal over 3–6 months for improved skin support; natural-looking outcome without altering facial structure.
  
• Model guide: Fish Bone L has wider barb spacing for broad-area lifting. Fish Bone W has denser barbs for stronger anchoring and precise local lifting. 
  

PDO VS PCL VS PLLA

• Compared to smooth/mono PDO threads: Fish Bone provides mechanical lift, not just collagen stimulation. 
  
• Compared to PLLA threads: PCL has a longer absorption cycle (~12–18 months) for more sustained results. 
  
• Compared to standard PDO cog threads: the bidirectional fish bone barb pattern distributes tension more evenly and resists displacement.
  

Who It's For

Use the following to quickly assess whether this thread suits your current skin condition:

• Skin condition: Mild to moderate skin laxity — facial contours beginning to soften, but not yet requiring surgical intervention
  
• Age range: Generally 30–60 years old; particularly suited to those aged 35–55 experiencing early sagging, deepening nasolabial folds, or an undefined jawline
  
• Anti-aging goals: Seeking a natural lift without changing facial expression or structure; looking for a non-surgical option or a maintenance solution between other treatments
  

Not recommended if: There is active infection in the treatment area, uncontrolled autoimmune conditions, known allergy to absorbable suture materials.

Safety

PCL (Polycaprolactone) is a biocompatible, fully absorbable medical-grade material with a well-established clinical track record. It breaks down naturally in the body with no removal required.

• Individually sterile-packaged to medical device manufacturing standards
  
• Gradual absorption over approximately 12–18 months — no sudden degradation risk
