Face Threading: Technique & Results
By AuroThread R&D Team | Updated September 2026 | 12 min read
Face threading, in the aesthetic sense, is the placement of absorbable PDO, PCL or PLLA threads beneath the skin to reposition tissue and stimulate collagen. It is a technique-driven procedure: the same thread placed in the wrong plane, along the wrong vector, or with the wrong introducer will produce a poor result or a complication, while the correct combination produces a predictable one. This article is written for professionals who want the technical picture — planes, instruments, entry points, design mapping and the timeline on which results are assessed — rather than a consumer overview. The material fundamentals sit in the complete PDO threads guide.
The term itself causes a great deal of search confusion, and it is worth dealing with that first. "Threading" in everyday language usually refers to hair removal with a twisted cotton thread, a technique with no relationship at all to aesthetic thread placement. Because the two share a word, some readers arrive at clinical material expecting something entirely different. The distinction is covered below and should be made explicit in patient-facing copy as well, both for clarity and for search intent.
The material that follows is educational and is intended for licensed, trained practitioners and for readers with a professional interest. It is not a training substitute and it is not a treatment protocol. Placement must be performed by licensed, trained practitioners working within their scope of practice, with appropriate training in facial anatomy and in the specific devices used.
What "Face Threading" Means — and What It Does Not
In aesthetic practice, face threading means inserting a sterile, absorbable thread through a fine needle or a blunt cannula into a chosen plane of the face, then withdrawing the introducer so that the thread remains in position. The thread may be smooth, twisted into a screw, cut with barbs or cogs, or configured as a mesh or multi-thread, and each configuration is suited to a different task. The procedure is minimally invasive, performed under local anaesthesia, and leaves no surgical incision.
It does not mean eyebrow threading, upper-lip threading or any other form of hair removal. Those treatments use a doubled cotton thread rolled across the skin surface to trap and remove hair, and they involve no needle, no implant and no clinical depth. The overlap in vocabulary is unfortunate but persistent, and clinics that publish educational content do well to state the difference plainly at the top of the page so that the right readers continue and the wrong ones are not misled.
Why the wording matters for search intent
The vocabulary problem is not only a curiosity; it affects how a clinic is found. A patient searching for "threading" may want hair removal, or may want a thread lift, and a page that does not distinguish the two attracts the wrong enquiries while confusing the right ones. Professional content is more useful when it states the clinical meaning early and uses the term consistently thereafter, reserving the hair-removal sense for a single clarifying sentence. The same discipline applies to "thread lift" and "face threading": the terms are related but not interchangeable, and a clinic writing for patients should decide which term it will own and then use it consistently across its content.
It is also worth separating face threading from the wider family of thread-based procedures. The face is the most common treatment area, but threads are also used at the neck, body and in other applications, and the technique differs by area. Within the face, the plane, the vector and the introducer change from zone to zone, which is why a single description of "how to thread a face" is less useful than a zonal approach. The clinical goals that drive those choices are set out in pdo thread lift face.
Planes of Dissection: Choosing Needle Versus Cannula
The plane in which a thread sits determines what it can lift, how much resistance it meets and which structures lie within reach of the introducer. Threads are placed in the subcutaneous tissue and in the supra-SMAS layer, with the exact depth chosen for the zone and the design. A thread placed too superficially may be visible or palpable; placed too deeply, it may fail to support the tissue it was intended to lift and may bring deeper structures into contact with the introducer.
The introducer is chosen to match the plane. A sharp needle cuts through tissue, which makes it efficient for fine, superficial placements where a clean track is needed, but it also means the tip will continue through whatever lies in its path. A blunt cannula separates tissue along a natural plane rather than cutting across it, which makes it more forgiving near vessels and nerves and is why heavier structural designs are supplied for cannula use only. In practice, the choice of plane and the choice of introducer are made together rather than in sequence.
Depth also interacts with the design. Fine mono threads in the 26G–30G range are supplied with a sharp needle and are designed for superficial work, while the heaviest cog design in the range, Cog 6D at USP-1, is supplied with a cannula only. The intermediate cog designs sit between the two. Deciding the plane first and then selecting the introducer that can safely reach it is the sequence that avoids most avoidable problems. The broader treatment context is covered in face lift with PDO threads.
Sharp Needle, Blunt L and W Cannula: When and Why
Three introducer types dominate face threading. The sharp needle is the workhorse for fine threads: mono, mono screw, tornado and tornado screw are all supplied with a sharp needle in gauges from 26G to 30G. The blunt L cannula has a curved tip that allows the practitioner to steer around structures after a small entry point, and the blunt W cannula uses a different tip geometry suited to other track shapes and entry angles. The third family matters most for cog designs, where the introducer must accommodate a larger structure without cutting a track wider than necessary.
The design constraints are explicit in the range. Cog 6D, at 19G and 100 mm in USP-1, is blunt-only at USP-1 and has no sharp-needle version, reflecting both the size of the structure it carries and the depth at which it is used. Lighter cog designs are USP-2 and are available with a sharp needle or with an L cannula; Cog 4D additionally offers a W cannula option, and bidirectional Cog 4D follows the same pattern. Cones cog, molding, multi, mesh, nose and eye threads are all supplied with a cannula, and double needle threads are offered with either a W or L cannula or a sharp needle at USP-2.
The comparison below summarises how the three introducers differ in practice. It describes general behaviour rather than a rule for any particular case; the selection is a clinical decision made per zone and per design.
| Aspect | Sharp needle | Blunt L cannula | Blunt W cannula |
|---|---|---|---|
| Tissue behaviour | Cuts a track through tissue | Separates tissue along a plane | Separates tissue along a plane |
| Typical designs | Mono, mono screw, tornado, tornado screw; Cog 3D/4D | Cog 3D/4D, Cog 6D, cones cog, molding, multi, mesh, nose | Cog 4D, Cog 6D, molding, eye, double needle |
| Typical gauges | 19G–30G depending on design | 18G–30G depending on design | 19G–30G depending on design |
| Point to note | Tip continues through tissue in its path, so the plane must be kept | Steerable after a small entry point; used where structures must be avoided | Tip geometry suits particular track shapes and entry angles |
Matching the introducer to the design, not the other way round
It is tempting to choose a thread first and then work out how to introduce it, but the safer sequence runs the other way. The intended plane, and the structures lying near it, determine what the introducer must be able to do, and that in turn narrows the designs that can be used. A practitioner who wants the holding power of a heavier cog must accept a cannula and the entry geometry that comes with it; a practitioner who needs the precision of a fine track must accept the smaller structure a sharp needle can carry. Working within those constraints produces a plan that can actually be executed, rather than one that has to be abandoned mid-procedure.
One practical consequence is that a stock list must match the techniques a clinic actually performs. A practitioner who uses sharp-needle fine threads and blunt-cannula cog anchors needs both families in stock; a practitioner who works exclusively with cannula-based structural designs does not. Multi thread illustrates the constraint clearly: it is supplied with an L cannula only, in ten lines at 23G or twenty lines at 21G, at USP 5-0.
Entry Points and Vectors by Facial Zone
Entry points are chosen so that the intended vector can be followed in a single pass without crossing structures that should be avoided. In the upper face, entry is commonly placed within the hairline or at the temporal region so that the track can follow an upward and outward vector toward the brow; the temple entry is also useful for the mid-face, where the vector runs upward and outward toward the temporal region, allowing the thread to support the cheek along the direction that ageing has reversed.
The lower face is approached differently. Jawline entry points are typically placed near the ear or just below it, with the vector running upward and back along the mandibular border, and nasolabial work runs upward and outward from the perioral region. The neck, when treated, is approached with an upward and back vector. In each case the entry point is positioned so that the length of thread used is spent on the area being supported rather than on the distance from the entry to that area.
Vector consistency across zones is what distinguishes a planned treatment from a sequence of local passes. The upper face, mid-face and lower face should be assessed together so that the vectors do not compete, and the entry points chosen reflect that assessment. Where several zones are treated, the resulting plan is closer to the whole-face approach described in full face PDO thread lift than to any single-area technique. Thread length availability also shapes the plan, since the range runs from 13 mm in fine mono up to 140 mm in double needle designs, and each zone needs a length that reaches its target without waste.
Mapping Thread Design to Technique
Each design family implies a technique. Mono threads at USP 6-0 or 7-0 in 26G–30G are placed in numbers, in a superficial plane, to cover an area and encourage a collagen response; the technique is repetitive and orientated around even coverage rather than load-bearing. Screw and tornado designs are used where volume and a denser local response are wanted in a small area, with the tornado screw able to "stimulate collagen twice more than normal Screw type" according to the catalogue.
Cog designs are the structural family, and the catalogue describes them as being designed to "conceive, fix and support the skin tissue in 3/4/6 directions for a long-term result and an effective and smooth anchoring." The technique changes accordingly: fewer threads, each placed deliberately, with attention to the fixation point and to the direction in which the cogs engage. Cone cog, molding, nose and eye designs each carry their own placement conventions, and the mesh thread — twelve pieces of USP 5-0 PCL twisted into one thread, available in PCL and PLLA only — is a wide-coverage design with a volume effect rather than a lifting technique in the narrow sense.
Matching design to technique is also a matter of recognising when a design is unsuitable. A practitioner who wants a structural result but has only fine threads available cannot substitute quantity for anchoring, and a practitioner working in a mobile area may find that a heavy design creates more distortion than support. The relationship between the plan and the material is discussed further under PDO facelift, and the practical expectations for patients are described in what to expect from PDO threads for the face.
Technique and Complication Avoidance
Most complications in face threading are technical rather than material. Asymmetry usually follows inconsistent vectors or uneven tension between sides; dimpling and visible or palpable threads follow placement that is too superficial or a track that has been over-tightened; infection follows breaches in aseptic technique; and injury to deeper structures follows an introducer travelling further than intended. Each of these has a technique answer, and each is reduced by working to a plan rather than improvising zone by zone.
Introducer choice is central. A sharp needle continues through tissue in the direction it is pointed, so the practitioner must maintain the intended plane throughout the pass and control depth deliberately. A blunt cannula separates along a plane and is more forgiving near vessels and nerves, which is why heavier structural designs are supplied for cannula use only at USP-1. Understanding the anatomy of the zone — what lies at the depth being used and what lies just beyond it — is the foundation on which both choices rest.
Tension is the other recurring theme. Structural threads are designed to hold, and over-tightening produces distortion that is visible and often uncomfortable. The catalogue lists discomfort for PDO as slight, for PCL as none and for PLLA as strong, which is relevant when planning a larger treatment area, but the discomfort profile of the material does not compensate for excessive tension. Post-procedure review is part of the technique as well: an early follow-up lets the practitioner confirm symmetry and address any issue while it is still correctable.
Why Product Quality Matters Alongside Technique
Good technique depends on the material behaving predictably. A thread that is not sterile, that carries heavy-metal residues or that varies in gauge from lot to lot undermines a carefully executed placement, and the practitioner has little way of detecting those problems at the point of use. This is why the specification of the product is as much a part of clinical safety as the technique itself.
The AuroThread range is EO-sterilised, heavy-metal free, CE marked, manufactured under ISO 13485 in a GMP-certified facility, supplied with a two-year shelf life and traceable by batch, and the PDO raw material is USP Class VI. For PLLA, the material is shipped nitrogen-packed, which reflects its sensitivity and should be handled according to the instructions for use. Traceability is the element most often overlooked at purchase and most valued afterwards, because it is what allows a complaint to be investigated against a specific lot.
Quality also shows up in the consistency of the range itself. A practitioner who knows that mono threads run from 26G to 30G at 13–90 mm, that cog designs are available in defined gauges and lengths, and that specific designs are cannula-only at defined USP sizes can plan a treatment around the products rather than discovering a mismatch in theatre. Instructions for use are supplied in English, Spanish, French, Arabic and Portuguese, which matters for clinics training staff across markets.
Assessing Results on a Timeline
Results after face threading are assessed on a timeline, and judging them immediately after the procedure is misleading. The early appearance is a combination of the positional change, local swelling and the tissue response to the pass, which means an initial impression is often not the final one. Practitioners who photograph the face from standardised angles before and after, and again at follow-up, are in a much better position to judge the treatment honestly.
Early review versus late review
Two review points serve different purposes and should not be conflated. An early review, within the first days, is about safety and symmetry: it is the moment to confirm that the face has settled evenly, that nothing is unduly tight and that aftercare is being followed. A later review is about the result: it compares the face with the pre-treatment photographs at a point where swelling has resolved and the collagen response has begun, and it is the point at which maintenance can sensibly be planned. Judging a result at the first review alone is a common source of unnecessary anxiety, while skipping the early review removes the chance to correct a problem while correction is still straightforward.
The material's own timing then takes over. PDO absorbs in 3-6 months, a result window of 6–9 months. PCL absorbs in more than 2 years, biodegradation at 16–24 months, a result window of 12–18 months, up to 24, and a tissue-repairing effect reported for up to two years. PLLA absorbs in 2 years or more, biodegradation at 14–18 months and a result window of 18–24 months. Collagen laid down during these periods continues to influence the result beyond the material's presence, which is why a face can remain stable after the thread itself has gone.
Assessment should therefore be structured around the review appointment rather than the day of treatment, and should compare the same views under the same lighting. Where the result is judged against the plan, the review also becomes the moment at which the next interval is set, and the material chosen will largely determine what that interval is. Documenting the designs and the plan at the time of treatment makes this review far more precise.
Training, Scope of Practice and Responsibility
This article is educational material for professionals and is not a training substitute. Face threading is an invasive procedure that requires training in facial anatomy, in plane selection, in the specific introducers and designs to be used, and in the recognition and management of complications. Reading about a technique is not the same as performing it under supervision, and neither substitutes for the demonstration, observation and supervised practice that competent training provides.
Scope of practice also varies by jurisdiction, and practitioners are responsible for working within the rules that apply to them. Some markets restrict who may place threads; some require specific qualifications; and some regulate the products that may be imported and used. Reputable suppliers make documentation available so that buyers can confirm compliance, but it remains the practitioner's responsibility to work lawfully and within their scope.
Responsibility extends to patient communication. Patients should understand what the treatment can and cannot do, how long the result is expected to last, what the aftercare involves and what the risks are. A practitioner who can explain the plane, the design and the vector in plain language is also a practitioner who is less likely to be congratulated for a result the patient did not understand in the first place. Educational content of this kind is a supplement to that conversation, never a replacement.
Sourcing Thread for Professional Use
Clinics and distributors sourcing thread for professional use need the range, the documentation and the supply terms to be predictable. AuroThread, the thread division of Auro Technology Limited, sells factory-direct to clinics and distributors in more than 30 countries. Standard stock configurations commonly start from 50 boxes (500 units) with flexible mixing across gauges and lengths, and free evaluation samples of 2–5 units are available to qualified buyers and credited toward the first bulk order, which allows a practitioner to trial designs before committing to stock.
For those building their own line, OEM and private-label options cover needle branding, sterile pouch and outer carton design, custom gauge and length, and multi-language instructions for use, with first runs typically from around 1,000 boxes. Lead time on repeat orders of standard stock is typically 7–15 days, while first-run OEM production generally runs 15–30 days. Express courier shipping takes approximately 3–7 days, European railway freight 15–20 days and sea freight 25–35 days, under FOB, CIF or DDP terms with payment by T/T or PayPal.
The full range, including PDO, PCL and PLLA materials, is catalogued by family in the PDO thread collection, and a quotation covering mixed SKUs is straightforward to obtain. Requests are answered with tiered wholesale pricing, lead time and the relevant CE / ISO documentation, typically within 24 hours. All figures given here are indicative and confirmed at quotation.
Frequently Asked Questions
Is face threading the same as eyebrow threading?
No. In everyday use, threading often refers to hair removal with a twisted cotton thread. Face threading in aesthetics refers to the placement of absorbable PDO, PCL or PLLA threads under the skin for lifting and collagen stimulation. The two are unrelated procedures that happen to share a word.
What is the difference between a sharp needle and a blunt cannula?
A sharp needle cuts through tissue, which makes it efficient for fine mono threads but requires the tip to be kept in the plane. A blunt L or W cannula separates tissue along a natural plane, which is safer near vessels and nerves. Heavier cog designs such as Cog 6D (USP-1) are supplied with a cannula only, while lighter Cog 3D and 4D (USP-2) are available with a sharp needle or a cannula.
Which plane are threads placed in?
Threads are placed in the subcutaneous and supra-SMAS planes, depending on the zone and the design. The plane of dissection determines the lift, the risk to deeper structures and the choice of needle or cannula; it is a core part of the technique and is decided per zone.
How long does a face threading procedure take?
Time depends on the number of zones and threads placed. Fine mono placement and full cog anchoring use different amounts of time, and a staged plan spreads the work across visits. The practitioner sets the schedule after assessing the face.
How are results assessed after threading?
Results are assessed on a timeline rather than immediately. Early changes include swelling and the tissue response; the material then absorbs over its characteristic window (PDO 3-6 months; PCL more than 2 years; PLLA 2 years or more) while collagen production continues. Follow-up appointments let the practitioner compare photographs and plan maintenance.
Why does product quality matter if the technique is good?
Even excellent technique depends on the material behaving predictably. AuroThread supplies PDO made from USP Class VI raw material, EO-sterilised, heavy-metal free and traceable by batch, manufactured under ISO 13485 in a GMP-certified facility and CE marked, with a two-year shelf life. Traceability also matters if a complaint has to be investigated.
Can face threading be learned from an article?
No. This article is educational material for professionals and is not a training substitute. Placement must be performed by licensed, trained practitioners, and supervised clinical training is required before treating patients. A supplier's instructions for use support correct handling but do not replace training.
