Auro PLLA Cog 3D Lifting Threads 19G 21G Cannula

The balanced 120° radial grip and progressive collagen-induction action of PLLA Cog 3D are optimized for thin-skinned planes and moderate gravitational descent:

• Lateral Eyebrow & Temporal Fox-Eye Lift: 21G 60mm (L-Cannula) or 23G 60mm (Sharp) (Recommended: 2–3 threads per side) — Elevates sagging brow tails with smooth fascial gliding and zero visible ridges.
• Mid-Face & Malar Cheek Restoration: 19G 100mm or 21G 100mm (L-Cannula) (Recommended: 3–4 threads per side) — Restores flattened cheek fullness through mechanical elevation combined with ongoing collagen volumizing.
• Jawline Refinement & Mild Jowls: 19G 100mm or 21G 100mm (L-Cannula) (Recommended: 3–5 threads per side) — Defines mandibular contours while gradually firming overlying lax skin.
• Nasolabial Fold Perimeter: 21G 100mm (L-Cannula) (Recommended: 2–4 threads per side) — Relieves soft tissue sagging above smile lines without over-pulling facial expressions.
• Submental Tightening & Neck Laxity: 21G 100mm (L-Cannula) (Recommended: 2–4 threads per vector) — Tightens mild under-chin skin redundancy and thickens delicate neck tissue.

• CE Certified Medical Device: Precision-manufactured under cleanroom standards, ensuring strict tensile consistency and 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 moisture-sensitive PLLA polymers from ambient humidity and UV degradation during international transit.
• Bioresorbable Biopolymer: 100% metabolized via natural Krebs cycle pathways into lactic acid, water (H2O), and carbon dioxide (CO2), leaving zero synthetic residue or permanent foreign bodies.

Q1: Why choose PLLA Cog 3D instead of PLLA Cog 6D for the temporal brow and upper cheek areas?
A: The temporal, lateral eye, and upper cheek areas have very thin subcutaneous fat padding. Cog 6D has barbs protruding in 6 dense planes, which can create visible skin ridges or dimpling in thin tissue. Cog 3D spaces its barbs across 3 balanced planes (120° apart), allowing the suture to nest smoothly along the deep temporal fascia. It delivers crisp lateral vector elevation with significantly lower insertion resistance and zero risk of surface irregularity.

Q2: How does PLLA Cog 3D differ in feel and longevity compared to PDO Cog 3D?
A: PDO Cog 3D provides strong immediate mechanical grip but hydrolyzes within 6–8 months, with aesthetic effects softening around 1 year. PLLA is a stiffer, crystalline polymer that functions as a continuous biostimulator. While both share the same 3D barb geometry, PLLA Cog 3D triggers active Type-1 collagen synthesis over 12–18 months as it dissolves, meaning tissue fullness and firmness continue to peak at months 3 to 6 and last for 18–24+ months.

Q3: How can practitioners prevent surface puckering or dimpling with PLLA 3D barbs?
A: Because PLLA is a firmer material than PDO, ensuring placement strictly in the deep subcutaneous/pre-fascial plane is essential. If a single barb catches the superficial reticular dermis upon cannula withdrawal, do not pull or cut the suture. Immediately apply firm thumb pressure over the dimpled point and perform a sweeping manual stroke backward toward the insertion point. This gently frees the superficial barb while leaving the deep fascia anchors firmly locked.

Q4: What should patients expect regarding immediate lift versus progressive volume improvement?
A:
• Day 1 to 30 (Immediate Mechanical Repositioning): The 3D barbs provide immediate diagonal suspension of descended skin vectors.
• Month 2 to 6+ (Autologous Collagen Ingrowth): PLLA micro-hydrolysis actively recruits fibroblasts, creating a thick sheath of new collagen around the 3D suture tract. This restores natural dermal thickness and subtle youthful plumpness to the cheek and temple apex.

Q5: Which needle delivery configuration should be chosen: 19G Cannula, 21G Cannula, or 23G Sharp?
A:
• 23G Sharp (60mm / 90mm): Best for delicate temporal entry points and direct fibrous anchoring where ultra-fine puncture marks are required.
• 21G L-Cannula (60mm / 100mm): The gold standard for brow tails and upper cheeks, providing smooth, atraumatic passage around facial nerves with minimal bruising.
• 19G L-Cannula (100mm): Indicated for heavier lower-face vectors and thicker mid-cheek skin requiring maximum structural support.
