High-Tensile Medical PDO Threads

Deenora® Medical PDO Threads are safe, bioabsorbable lifting and tightening threads made from 100% pure Polydioxanone. Designed for professional aesthetic clinics, medspas, and doctors, our threads provide an immediate lifting effect while naturally stimulating your skin’s own collagen production. Over 6 to 8 months, the threads safely dissolve inside the body, leaving behind a firm, natural collagen structure that keeps the skin lifted and youthful for 12 to 18 months.

1. How to Choose the Right PDO Thread (By Treatment Area & Goal)

Different areas of the face require different thread structures. Here is how to quickly select the right Deenora PDO thread for your patient’s specific needs:

• Face Lift, Jowls & Jawline (For Sagging Skin & V-Line Contouring)

• Best Choice: Cog Barbed Threads (3D/4D/6D) or Molding Cog Threads
• Recommended Sizes: 18G, 19G, 21G (Lengths: 60mm, 100mm) with Blunt L-Type Cannula.
• Why It Works: Barbed threads have tiny hooks around the thread that grab and physically lift sagging tissue around the cheeks, jawline, and double chin. For heavier skin, Molding Cog offers the strongest hold to prevent slipping or dropping.

• Fox Eye & Eyebrow Lift (For Lateral Eye & Brow Elevation)

• Best Choice: Fox Eye Series / 21G Cog Threads
• Recommended Sizes: 21G (60mm) with Blunt Cannula.
• Why It Works: Designed to lift the outer tail of the eyebrow and create the trendy almond/fox-eye look. The blunt tip glides smoothly under the skin without damaging blood vessels, minimizing bruising and recovery time.

• Non-Surgical Nose Lift (Hiko Nose Bridge & Tip Definition)

• Best Choice: Hiko Nose Threads
• Recommended Sizes: 19G, 21G (38mm for Nose Tip / 50mm for Nose Bridge).
• Why It Works: Nose threads have a thicker, stiffer core to push up the nasal tip and create a straighter, higher nose bridge without the risk of filler migration or vascular blockage.

• Neck Lines, Forehead & Under Eyes (For Fine Wrinkles & Skin Firming)

• Best Choice: Mono (Smooth) Threads
• Recommended Sizes: 29G, 30G (Lengths: 25mm, 38mm).
• Why It Works: Ultra-thin smooth threads are inserted like a mesh under delicate skin. They don't lift heavy tissue, but they build thick, new collagen to smooth out fine lines, tighten crepey neck skin, and brighten dark under-eye areas without lumps.

• Smile Lines & Deep Folds (For Volume & Crease Filling)

• Best Choice: Screw / Tornado Threads
• Recommended Sizes: 26G, 29G (Lengths: 38mm, 50mm).
• Why It Works: The coiled spiral shape gives extra volume and creates more collagen surface area, making it ideal for plumping deep smile lines (nasolabial folds) and marionette lines around the mouth.

2. Molding Cog vs. Regular Cut Cog: Why Molding Threads Hold Better

Many practitioners ask why some PDO threads lose their lift after just a few weeks. The secret is in how the barbs are made:

• Traditional Cut Barbed Threads: The barbs are cut into the thread with a blade. This cuts away up to 30% of the thread’s core, making the thread weaker and prone to snapping or peeling under facial expression.
• Deenora® Molding Cog Threads: The barbs are molded under high pressure without cutting into the thread core. The solid core stays 100% intact, making the thread almost 3 times stronger. It holds heavy sagging skin firmly in place without slipping, snapping, or losing lift.

3. Material Guide: PDO vs. PCL vs. PLLA at a Glance

• PDO (Polydioxanone): The most popular and versatile choice. Lasts 12 to 18 months (dissolves in 6–8 months). Best for all-around facial lifting, sharp jawlines, and collagen building.
• PLLA (Poly-L-Lactic Acid): Focuses heavily on collagen production and volume restoration. Dissolves in 12 to 18 months, best for hollow cheeks and deep folds.
• PCL (Polycaprolactone): The longest-lasting material. Dissolves over 18 to 24 months. Highly flexible and soft, ideal for areas with constant facial movement.

5. FAQS

Q1: What is the difference between Sharp Needles, L-Type Cannulas, and W-Type Cannulas?

• Sharp Needles (26G–30G): Designed for Mono and Screw threads placed just under the skin. The sharp bevel allows effortless skin puncturing for quick, superficial wrinkle treatments.
• L-Type Blunt Cannulas (18G–23G): Feature a smooth, rounded closed tip with a side opening. Best for standard Cog and Molding thread lifting. It gently pushes blood vessels and nerves aside without cutting them, which drastically reduces bruising, prevents bleeding, and ensures a safer procedure.
• W-Type Cannulas (18G–21G): Feature a specially tapered, slightly pointed blunt tip. Designed for dense, fibrous, or previously treated tissue planes. It glides through tough subcutaneous layers with less push resistance than an L-type, while still protecting major blood vessels from trauma.

Q2: How many PDO threads are typically needed per treatment area?

• Full Face & Jawline Lift: Usually requires 8 to 12 Cog or Molding threads (4 to 6 threads per side) to lift the cheeks, jowls, and lower face.
• Fox Eye & Eyebrow Lift: Typically uses 2 to 4 Cog threads per side (4 to 8 threads total) placed into the temporal hairline.
• Non-Surgical Hiko Nose Lift: Generally uses 4 to 8 Nose threads (1 to 2 for the columella tip and 3 to 6 along the nasal bridge).
• Neck Lines & Double Chin: Commonly uses 20 to 30 Mono or Screw threads placed in a cross-hatch grid for collagen tightening.
• Under-Eye Tear Troughs: Typically uses 10 to 20 ultra-fine Mono threads (5 to 10 per eye) to thicken thin under-eye skin.

Q3: How long does it take to see results, and what is the typical recovery downtime?

• Immediate vs. Long-Term Results: Patients see an immediate mechanical lift right after the procedure. Over the next 2 to 3 months, natural collagen production peaks, resulting in tighter skin, smoother texture, and a more defined contour that lasts 12 to 18 months.
• Downtime: Because PDO thread lifting is minimally invasive, recovery is fast. Most patients experience only mild swelling or pinpoint bruising for 2 to 5 days, and can return to daily activities immediately.

Q4: How can practitioners prevent skin puckering, dimpling, or visible thread lines?

• Correct Depth is Key: Never place barbed Cog threads too superficially in the dermis. Cog and Molding threads must be placed strictly in the subcutaneous fat layer (pre-SMAS plane).
• Release Surface Tension: If mild skin dimpling occurs at the entry point after pulling the thread, gently massage the skin in the opposite direction or release the subcutaneous tethering with a cannula to ensure a smooth, natural surface before trimming the thread end.
