Description
N-Fix Thread 21G/100mm is a premium inner cog PDO lifting thread from N-Finders that uses micro-punching sculpting technology to create dense, dual-cut barbs along a thicker polydioxanone thread. The design delivers strong tissue grasping and a stack-nesting fixation effect within the SMAS and subdermal planes, allowing effective lifting and repositioning of facial tissues such as the cheeks and jawline, as well as selected body areas, while stimulating collagen production with minimal trauma when inserted through a fine cannula.
Bnefits
Premium inner cog PDO thread with multiple dual-cut barbs for strong tissue grasping and fixation.
Micro-punching sculpting technology creates dense inner cogs that promote a stack-nesting effect and stable tissue support.
Thicker PDO thread in a thin cannula provides powerful lifting capacity for midface, jawline and body indications.
Minimally invasive procedure with small puncture points and no large incisions, designed to reduce downtime compared with surgical lifting.
Stimulates neocollagenesis and elastin production, improving skin firmness, texture and elasticity over time.
Completely biodegradable PDO material that is gradually absorbed by the body while leaving a collagen scaffold.
CE-marked medical device manufactured to high quality standards for aesthetic thread lifting.
Pack of 6 sterile threads, convenient for facial lifting protocols and combination treatments with other PDO configurations.
Indications
Non-surgical facial lifting and contouring using PDO cog threads.
Lifting and repositioning of midface and cheek tissues.
Jawline definition and lower-face contour improvement.
Support and tightening of mild to moderate facial laxity, including jowl areas.
Adjunctive lifting and support for body treatments in suitable areas (for example abdomen, thighs, buttocks, upper arms) as per practitioner protocol.
Combination use with other PDO thread types (such as N-Cog or mono threads) for comprehensive lifting and skin rejuvenation strategies.
Use in adult patients seeking minimally invasive lifting and tightening, carried out by trained medical professionals.
Each thread supplied individually packed in a sterile sachet or blister inside the box.
Outer carton clearly labelled with product name, configuration (21G/100mm), lot number, expiry date, CE mark and manufacturer details.
In larger manufacturer cartons, N-Fix may also be supplied as multiple inner pouches (for example, up to 60 threads per case) depending on distributor packaging.
Usage
For use only by trained, qualified and appropriately insured medical or aesthetic professionals experienced in PDO thread lifting techniques.
Perform a full medical history, facial or body assessment and photographic documentation before treatment; obtain informed consent including discussion of risks, benefits and alternatives.
Cleanse and disinfect the treatment area thoroughly with an appropriate skin antiseptic and maintain aseptic technique throughout the procedure.
Mark vector lines and entry/exit points according to the planned lifting pattern (for example, cheek and jawline vectors for lower-face lifting).
Administer local anaesthesia at planned entry and, if required, exit points following local protocols and product labelling.
Insert the 21G/100 mm cannula or needle along the marked vector in the correct plane (typically subdermal or SMAS level) while avoiding vital structures; confirm smooth passage without excessive resistance.
Deploy the N-Fix PDO cog thread by advancing the cannula and then withdrawing while holding tension on the thread, ensuring the cogs engage the tissue along the vector.
After insertion, gently compress and mold tissues along the vector to optimise cog engagement and the final lifting effect.
Trim excess thread at the entry point as needed and apply sterile dressings or small adhesive strips if indicated.
Advise the patient to avoid exaggerated facial movements, pressure, massage, dental work, intense exercise, saunas and tanning beds for a period specified in your protocol (often 1–2 weeks) to allow stable integration of the threads.
Monitor the patient for early complications such as dimpling, asymmetry, visible threads, pain or signs of infection, and manage promptly according to established complication-management guidelines.
Do not reuse threads or needles; dispose of all used materials as clinical sharps waste according to local regulations.
Always follow the latest official N-Finders and local PDO thread guidelines and adapt technique to the specific anatomy and indication.
Contraindications
Known hypersensitivity or allergy to polydioxanone (PDO) or any materials used in the device.
Active infection, inflammation, acne, dermatitis or herpetic lesions at or near the intended treatment area.
Tendency to develop keloids or hypertrophic scarring, or history of abnormal scar formation in areas to be treated.
Severe coagulation disorders, uncontrolled anticoagulant therapy or significant bleeding diathesis that cannot be adequately managed.
Severe systemic illness, uncontrolled diabetes, severe autoimmune disease or significant immunosuppression unless the treating physician determines the benefit clearly outweighs the risk.
Pregnancy or breastfeeding, due to lack of safety data for PDO thread lifting in these populations.
Unrealistic expectations or inability to comply with post-procedure care instructions.
Previous permanent fillers, implants or foreign bodies in the planned vector path unless managed by clinicians with specific advanced experience and risk mitigation.
Any additional contraindications or restrictions specified in the official N-Finders or distributor instructions for use for PDO threads.
Adverse Effects
Transient pain, tenderness or discomfort along the insertion paths or at entry points.
Bruising, swelling and erythema in the treated area, usually resolving within days to a couple of weeks.
Skin dimpling, puckering or irregularity along the thread vector, often improvable with massage or minor corrective techniques.
Palpable or occasionally visible threads, particularly in thin skin or if threads are placed superficially.
Asymmetry or insufficient/over-lifting requiring adjustment, additional threads or, rarely, removal.
Infection, including cellulitis or abscess formation, particularly if aseptic technique is compromised.
Hematoma or bleeding along the tunnelled path.
Nerve irritation or transient sensory changes in the treated area if threads are placed near superficial nerves.
Thread migration, breakage or extrusion in rare cases, possibly requiring intervention.
Rare but serious complications such as vascular compromise or tissue necrosis if placed improperly or combined with other procedures in high-risk zones.
Any other adverse reactions described in the PDO thread lifting literature or the specific N-Fix / N-Finders usage guidelines should be discussed with the patient before treatment.
Storage Conditions
Store in a clean, dry environment at a stable room temperature as specified on the packaging (commonly around 15–25 °C); avoid extremes of heat and cold.
Keep threads in their original sterile pouches and outer carton until use to maintain sterility and protect from physical damage and light.
Do not use if the sterile barrier is damaged, wet, punctured or opened, or if there is any visible sign of compromise to the packaging.
Do not use after the expiry date printed on the packaging.
Protect from direct sunlight, moisture and contamination in clinical storage areas.
Duration
The PDO thread itself typically undergoes hydrolytic absorption over approximately 6\u20138 months, while the lifting and collagen-stimulating effects can persist for around 12\u201318 months depending on the patient\u2019s age, skin quality, lifestyle, treatment area and number of threads used.
Onset
Mechanical lifting and contour improvement are usually visible immediately after placement, with progressive enhancement of skin firmness, texture and elasticity over the following 2\u20133 months as new collagen and elastin are produced around the threads.
