Product Overview
The Auro PDO Mono Thread 26G is a sterile, single-use polydioxanone (PDO) monofilament suture designed for subcutaneous implantation to stimulate collagen synthesis and progressive skin tightening. Unlike PDO cog threads engineered for mechanical lifting, this smooth, barb-free filament relies on a bio-stimulatory mechanism: once placed in the subdermal plane, it triggers fibroblast activation and de novo collagen production over 8–12 weeks.
Manufactured under ISO 13485 QMS in a GMP-certified facility, every unit carries CE marking, batch-level traceability, and EO sterilization documentation. Available for wholesale evaluation with free samples and OEM private-label options.

Key Features & Benefits
Clinical Performance
Collagen Bio-Stimulation
PDO filament triggers controlled fibroblast response, driving Type I/III collagen deposition over 8–12 weeks. Results develop progressively and naturally.
26G Precision Profile
0.45 mm OD with siliconized needle surface reduces tissue drag, enabling accurate subdermal navigation in thin-skinned zones (periorbital, perioral).
Complete Hydrolysis
PDO breaks down into H₂O and CO₂ within ~6 months. Collagen scaffolding persists 12–18 months post-absorption.
Violet-Dyed Visibility
D&C Violet No. 2 dye enables clear intraoperative visualization, reducing overlap risk and enabling precise placement verification.
Supply Chain Reliability
Batch Traceability
Unique lot ID links to raw material certificate, EO cycle log, and QC report — retrievable for regulatory audits.
Lot-to-Lot Consistency
Needle-thread junction tensile strength tested per USP <871> at every batch. Clinicians experience zero handling deviation between shipments.
Aseptic Packaging
Individual blister/foil pouch enables sterile transfer to operative field without compromising unused units.
Multi-Language IFU
Available in English, Spanish, French, Arabic, Portuguese. Regulatory dossier support for new-market registration.
Quality Certifications
ISO 13485 CE Marked ISO 10993 Biocompatible
Clinical Applications
- Periorbital Rejuvenation — Fine rhytides and creping in the infraorbital and lateral canthal regions. 26G enables precise placement in thin dermis.
- Nasolabial Fold Softening — Fanning or mesh-pattern implantation stimulates local collagen, reducing fold depth over 8–12 weeks.
- Midface Volumization — Grid-pattern placement across the malar region complements PDO cog thread lifting at the SMAS plane.
- Marionette Lines & Perioral Rhytides — Vertical insertion delivers targeted collagen reinforcement for early-stage tissue laxity.
- Neck & Decolletage — Horizontal threading at 10–15 mm intervals addresses crepey skin where lifting threads are contraindicated.
Safety Compliance: PDO mono threads are prescription medical devices for use by licensed professionals trained in thread-lifting techniques. Contraindications: active infection, known PDO hypersensitivity, autoimmune conditions, pregnancy/lactation. Adverse events (transient erythema, edema, bruising) should be discussed during informed consent. Full prescribing information in IFU.

Frequently Asked Questions
What is a PDO mono thread 26G and how does it differ from cog threads?
A PDO mono thread 26G is a smooth, barb-free polydioxanone monofilament that stimulates collagen through bio-stimulation rather than mechanical lifting. Cog threads use barbs for immediate tissue suspension; mono threads rely on fibroblast activation and neocollagenesis over 8–12 weeks for progressive, natural-looking tightening.
How long do PDO mono thread 26G results last?
The PDO filament hydrolyzes completely within ~6 months. However, the collagen scaffolding deposited during the remodeling phase persists for 12–18 months. Maintenance sessions at 12-month intervals are typically recommended.
What is the minimum order quantity for PDO mono thread 26G wholesale?
Wholesale MOQ: 50 boxes (500 units), with flexible gauge/length mixing. OEM private-label: typically 1,000 boxes for first-run, negotiable for existing Auro distribution partners. Contact
amanda@aurocn.com for a tailored quote.
Is the PDO mono thread 26G CE certified for Europe?
Yes. CE-marked under MDD 93/42/EEC. Each shipment includes CE-labeled packaging, Declaration of Conformity, and multilingual IFU. Auro's regulatory team can assist with EU Authorized Representative designation.
Which gauge of PDO mono thread is best for periorbital treatment?
The 26G (0.45 mm OD) is the largest commonly used mono gauge, preferred for nasolabial folds, marionette lines, and cheek volumization. For ultra-thin periorbital zones, 29G–30G threads minimize insertion trauma. Auro's full gauge range is available in the
PDO thread collection.
How should PDO mono thread 26G be stored?
Store at 5–30 °C in a dry environment, away from UV and humidity. Do not freeze. 24-month shelf life from sterilization date (printed on each pouch). Use immediately once pouch is opened; do not re-sterilize.
