Auro PDO Cog 3D Lifting Threads 19G 21G L Cannula

The balanced 3D radial distribution provides smooth tissue gliding and natural contouring, making it ideal for moderate descent and fine-angle lifting:

• Lateral Eyebrow & Temporal Fox-Eye Lift: 21G 60mm (L-Cannula) or 23G 60mm (Sharp) (Recommended: 2–3 threads per side) — Elevates sagging brow tails and opens lateral eye contours with minimal swelling.
• Mid-Face & Malar Cheek Elevation: 19G 100mm or 21G 100mm (L-Cannula) (Recommended: 3–4 threads per side) — Gently lifts descended cheek volume to soften moderate nasolabial folds.
• Jawline & Lower Cheek Definition: 19G 100mm or 21G 100mm (L-Cannula) (Recommended: 3–5 threads per side) — Pulls loose skin along the jawline upward toward the pre-auricular anchor.
• Marionette Line Perimeter: 21G 60mm / 100mm (L-Cannula) (Recommended: 2–4 threads per side) — Relieves soft tissue sagging at the oral commissures.
• Neck Laxity & Submental Tightening: 21G 100mm (L-Cannula) (Recommended: 2–4 threads per vector) — Tightens loose skin under the chin and along upper neck planes.

• CE Certified Medical Device: Manufactured under strict cleanroom standards, ensuring verified tensile retention and full tissue biocompatibility.
• 100% EO Gas Sterilized: Every blister pouch is individually treated with medical Ethylene Oxide (EO) gas for zero microbial contamination.
• 2-Year Sterile Shelf Life: Every pack is clearly stamped with a dedicated LOT number, manufacturing date, and 2-year expiration date.
• Protective Medical Aluminum Foil: High-barrier multi-layer foil pouches shield sensitive PDO polymers from ambient humidity and UV degradation during international transit.
• Completely Bioresorbable: Ultra-pure polydioxanone decomposes completely into water and carbon dioxide with zero synthetic residue or granuloma risk.

Q1: Why is Cog 3D specifically recommended over Cog 4D for the temporal Fox-Eye and lateral brow vectors?
A: The temporal and lateral orbital areas have extremely thin subcutaneous tissue with minimal superficial fat padding. Cog 4D's four-quadrant barbs can project directly upward toward the dermis in these thin zones, creating visible skin puckering or surface irregularities. Cog 3D’s 120° radial spacing allows barbs to nest flatly along the deep temporal fascia planes, providing crisp diagonal lateral traction without the risk of visible surface ridges or contour dimpling.

Q2: How does the 120° radial barb spacing reduce the risk of post-procedure skin dimpling (puckering)?
A: Surface dimpling occurs when a vertical barb catches the superficial reticular dermis too tightly. Cog 3D distributes tensile anchoring across three balanced 120-degree vectors, meaning barbs naturally grip the deeper fibrous septa laterally rather than catching the skin vertically. If minor skin puckering occurs immediately post-insertion, a gentle upward manual massage along the vector will instantly release the superficial dermal catch while preserving the deep fascia anchor.

Q3: What should practitioners do if the patient feels sharp tenderness or a "pinching" sensation when smiling?
A: In dynamic mid-face zones (such as the zygomaticus muscle border), patients may feel localized pinching during the first 5 to 7 days due to muscle contraction against the newly engaged barbs. This is completely normal and indicates active mechanical fixation. Practitioners should advise patients to limit exaggerated facial expressions; the sharp sensation naturally softens as tissue relaxes around the 3D barbs within 10 to 14 days.

Q4: Why choose a 21G L-Cannula instead of a 19G cannula for patient profile refinement?
A: While 19G is designed for dense, heavy jowls, a 21G L-Cannula requires a much smaller insertion entry point and generates significantly less shear resistance through fine facial planes. It allows seamless, atraumatic gliding around the infraorbital margin and lower cheeks, leaving almost invisible entry points at the hairline with virtually zero social downtime.

Q5: Can Cog 3D be safely adjusted or repositioned if tension is uneven during the procedure?
A: Yes, but only before cutting the distal suture tail. Before trimming, assess facial symmetry in a seated position. If slight over-correction or asymmetry is present, gentle retrograde skin smoothing toward the insertion point will release excess barb tension. Once symmetrical lift is confirmed, trim the suture tail under slight skin depression so the cut end retracts securely beneath the dermis.
