A thread lift in Singapore places absorbable PDO, PCL or PLLA threads under the skin through small entry points under local anaesthetic. Barbed threads hold a mildly descended jowl, cheek or brow in a repositioned place while collagen forms around them. Threads do not add volume or remove skin, so suitability is decided at assessment.
Thread lift in Singapore: the short answer
A thread lift in Singapore, or face thread lift, uses absorbable PDO, PCL or PLLA barbed threads to hold mildly descended tissue in a new position. Dr Sin Yong performs it as the Bliss Lift where tissue has slid but stays firm. Where the fascia has loosened, he plans the VF Lift – Vertical Facelift or Time Freeze Laser LCLR® instead.
What a thread lift is and how it works
A thread lift places absorbable sutures into the subcutaneous layer of the face, through a blunt cannula or fine needle, under local anaesthetic. Lifting threads carry small cogs or barbs along their length. Once a thread is in position and the tissue is drawn back along its vector, the barbs engage the fibrous septae of the subcutaneous fat and hold the tissue where it has been placed. Threads sit above the SMAS and do not enter it.
Two things then happen. The first is mechanical: the barbs hold descended tissue, such as a jowl, the lower cheek or the tail of the brow, closer to where it sat before it slid. The second is biological: the body lays down a capsule of collagen around the thread, which persists for a period after the polymer is broken down by hydrolysis and contributes some support along that line. That is the whole mechanism. A thread does not heat tissue, add volume or remove skin.
Mono, screw and cog threads
- Mono threads are smooth single filaments placed in a mesh pattern. They have no barbs and no lifting capacity; their purpose is a fibrotic response directed at skin firmness.
- Screw or tornado threads are filaments wound around the carrier needle, used where a little fullness along a line is wanted.
- Cog or barbed threads carry directional barbs and are the type that repositions tissue. These are what people mean by a thread lift. Some branded threads use small absorbable cones instead of barbs; the principle is the same.
How threads compare with focused ultrasound, radiofrequency and laser is set out under face lifting treatment.
Who a thread lift suits, and who should avoid it
A thread lift works where there is tissue to grip and somewhere to put it: mild to moderate descent of the jowls, mid-face or lateral brow, with facial volume reasonably preserved and skin thick enough that the thread sits beneath it without being seen or felt. Early jowling, the soft pocket at the corner of the jawline, is the most common reason people ask. A quick test: if the tissue can be lifted back by hand and looks right in that position, a thread may be able to hold it.
| Group | What it looks like | Why |
|---|---|---|
| Tends to suit | Early jowling, a soft jawline, a cheek that has descended but kept its volume, a brow tail that has dropped | There is mobile tissue to hold and skin to cover the thread |
| Does not suit | Heavy skin excess | Moving redundant skin produces bunching rather than a lift |
| Does not suit | Very thin, sun-damaged or very lean skin | A cog thread can be visible, palpable or dimple |
| Does not suit | Volume loss mistaken for sagging | Lifting a hollow moves it rather than filling it |
| Postponed | Active acne, infection or inflammation along the planned vectors | An infected thread tract is a serious complication |
| Assessed individually | A keloid tendency, a bleeding disorder or anticoagulants, pregnancy | Each entry point is a small wound |
There is no set age: some faces in their fifties suit threads and some younger faces are better served by volume restoration or energy-based treatment. Skin thickness, laxity and the choice of thread are covered under am I suitable for a thread lift, and the lower-face assessment on jowls and lower-face sagging.
Which thread to choose: PDO, PCL or PLLA, zone by zone
Every thread Dr Sin Yong places is dissolvable. The question is which polymer, because PDO, PCL and PLLA are broken down by hydrolysis at different rates, and that changes how the lift behaves over time. The slower the polymer resorbs, the longer it remains as a scaffold for collagen.
| Material | What it is | Relative resorption | Where it tends to be chosen |
|---|---|---|---|
| PDO (polydioxanone) | The polymer of standard absorbable surgical suture; firm, with limited stretch | Fastest, so its hold tapers first while the collagen track remains | Most jowl and mid-face vectors |
| PCL (polycaprolactone) | A more flexible, slowly hydrolysed polyester | Slowest of the three | Heavier tissue, vectors needing sustained support, or re-laying vectors after an earlier PDO lift has resorbed |
| PLLA (poly-L-lactic acid) | From the same family as injectable collagen biostimulators | Between PDO and PCL | A particular zone that calls for its handling; used less often |
The zone matters as much as the material. A face thread lift is a set of vectors, each chosen for one zone, and what a thread can hold changes between them.
| Zone | Vector | What it cannot lift |
|---|---|---|
| Mid-face and cheek | Oblique, from an anchor at the temple toward the cheek fat pad | A flat or hollow cheek, which is a volume question |
| Jawline and jowl | From in front of the ear along the jaw and down to the early jowl | Heavy jowls on loose skin, or a jawline blurred by compact fat or old filler |
| Lateral brow | Short threads from within the hairline, supporting the tail of the brow | Upper-lid skin resting on the lashes, which is an eyelid matter |
| Neck | Used selectively across the submental region | Vertical platysmal bands, which are muscular, and marked loose skin |
The materials are set side by side on PDO vs PCL vs PLLA threads, with area guides on jawline threads and eyebrow lift threads. Threads on the nose are a separate application, planned on its own: see nose thread lift.
What threads cannot do, and the alternatives
A thread repositions tissue it can grip. It does not remove skin, add volume or firm the skin surface, and it does not hold heavy tissue for long. People weighing a thread lift are usually also weighing HIFU, radiofrequency and a facelift. These are different mechanisms in different planes, not a ranking.
| Option | What it does | What it cannot do | Who it tends to suit |
|---|---|---|---|
| Cog thread lift | Holds a descended jowl, cheek or brow in a repositioned place | Add volume, remove skin or lift heavy laxity | Mild to moderate descent with preserved volume |
| VF Lift – Vertical Facelift | Volnewmer monopolar radiofrequency heating the dermis and subcutaneous layer | Move tissue on the day or remove skin | A fascia that has loosened so the whole lower face hangs |
| HIFU or Ultherapy | Thermal points at the SMAS and deep dermis, which contract and remodel | Reposition tissue on the day or remove skin | Early laxity where tightening at depth is the aim |
| Thermage FLX | Monopolar radiofrequency heating the dermis in bulk | Hold descended tissue | Laxity of the skin envelope |
| Filler or a collagen biostimulator | Restores volume where hollowing, not descent, is the problem | Lift heavy descent or remove skin | Volume loss that a thread would only move |
| Surgical facelift (referred on) | Repositions the SMAS and removes excess skin | Restore volume or change skin quality on its own | Heavy skin excess and marked descent |
Thread lift or filler?
Threads reposition tissue that has descended; filler replaces volume that has been lost. Adding filler to tissue that has descended adds weight to what is already low, and lifting a hollow with a thread moves it rather than filling it. Many faces show both, so the two are often planned together. Reversibility differs: hyaluronic acid filler can be dissolved, whereas absorbable threads resorb on their own timeline. How each mechanism is matched to a pattern of descent is set out on sagging face treatment, and the limits of threads on thread lift limitations.
Thread lift alternatives without filler: where VF Lift and Time Freeze fit
If you are considering a thread lift but would rather not have threads or filler placed, the deciding question is what has moved. Threads reposition tissue mechanically and need reasonably firm tissue to anchor to. Dr Sin Yong’s two protocols place nothing under the skin.
- A fascia that has loosened so the whole lower face hangs. Threads have little to anchor to here, and Dr Sin Yong recommends the VF Lift – Vertical Facelift instead. It heats the dermis and subcutaneous layer with Volnewmer monopolar radiofrequency along vertical vectors, and its Restore mode is used to stimulate the patient’s own fat in hollow areas such as the temples and lateral cheeks.
- Tightening, or heaviness, as the real need. Time Freeze Laser LCLR® tightens the dermis at several depths with a long-pulsed 755 nm and 1064 nm laser, and its Sculpting mode is directed at compact fat along the jowl and at settled filler. No redness, no downtime.
With no threads and no injected product, there is no filler to overfill, migrate or form lumps, and nothing is left under the skin. Change builds gradually and varies between people, and the heat-related risks are set out on each protocol page.
When a thread lift is still the better fit
Neither protocol moves tissue on the day. Where tissue has slid and the skin and fascia are still reasonably firm, threads can reposition it, with PDO, PCL or PLLA chosen zone by zone. Neither protocol removes folds of skin, which are referred to a plastic surgery specialist. A muscle pulling the mouth corners down answers to botulinum toxin, and a bony deficit may need a small amount of filler. Compare the two approaches on VF Lift vs thread lift, and read the wider approach on face lifting without fillers.
Thread lift risks and side effects
These are the recognised complications in the published thread-lift literature:
- A visible or palpable thread, more likely with thin skin or superficial placement.
- Extrusion: a thread end working out through the skin at the entry point, which is trimmed or removed.
- Infection along the thread tract, which may require thread removal and antibiotics.
- Dimpling or puckering that persists beyond the settling period; a dimple that does not settle can be released at review.
- Nerve irritation: transient altered sensation or, rarely, weakness where a thread passes near a nerve branch.
- Asymmetry, bruising and, uncommonly, haematoma.
- Thread migration or loss of hold, more likely if the early precautions are not followed.
Most are managed by the doctor who placed the thread, which is one reason to keep the procedure and its review in the same hands. What each looks like when a plan goes wrong is on thread lift gone wrong.
Does a face thread lift work? What the evidence says
A face thread lift does reposition tissue, but the published evidence on how well and for how long is thinner than its popularity suggests. That gap is the main reason some plastic surgery specialists are critical of thread lifts, and it is worth knowing before you book.
What the studies found
- Limited durability in most studies. A 2018 systematic review in Plastic and Reconstructive Surgery found that little substantial evidence on how well threads work, or on their complications, had been added in the previous decade. Most included studies showed very limited durability of the lifting effect, if any, and the two positive studies were sponsored by thread manufacturers.
- Early change partly from swelling. A 2009 study of an earlier barbed-thread system found only limited short-term improvement, which the authors attributed largely to swelling and inflammation after the procedure. When threads were combined with other procedures, scores were better than with threads alone.
- Newer absorbable threads. Today's PDO, PCL and PLLA threads differ from the systems studied then, and studies of them are growing. Most are small and short, so the evidence is still developing.
Why some doctors are sceptical
The criticism is less about threads themselves than about how they are sold. Threads are often marketed as a facelift without surgery, offered to faces with heavy skin excess they cannot hold, or sold in packages before anyone has examined the face. When that happens, the result disappoints and the complications listed above become more likely. A thread repositions tissue it can grip, and that is a narrow set of faces.
How this shapes Dr Sin Yong's approach
Dr Sin Yong keeps the selection narrow. Threads are planned only where tissue has slid while the skin and fascia are still reasonably firm. Where the fascia has loosened, he plans the VF Lift – Vertical Facelift instead, and where heaviness or skin-layer laxity is the real need, Time Freeze Laser LCLR®. Nothing is injected with either, so there is no filler to migrate or form lumps. No length of effect is promised for any of these, and the plan is set from what review shows. The limits are set out in more detail on thread lift limitations.
What to expect: assessment, procedure and recovery
The assessment. Dr Sin Yong examines the face at rest and in animation, palpates the jowl and cheek to judge how mobile the tissue is and how much is fat rather than skin, checks skin thickness over the intended vectors, and notes existing asymmetry, because a lift can make it more obvious if not planned around. Bleeding tendency, medicines, previous filler or threads and scarring history are taken at the same visit. The output is a thread plan, or a decision that threads are not the right tool.
The procedure. Vectors and entry points are marked with you sitting upright, because tissue falls differently lying down. The entry points and the path of each thread are numbed with local anaesthetic. The carrier is passed along each marked vector in the subcutaneous plane, the thread released and the tissue drawn back so the barbs engage, and symmetry is checked before the final threads go in. Most people describe pressure and pulling rather than pain.
Recovery. Recovery varies. Swelling and some bruising along the vectors, tightness when opening the mouth wide, tenderness at the entry points and small surface dimples are normal early on, and minor early asymmetry is common because swelling is rarely even. Wide mouth opening, vigorous facial massage, dental work and sleeping on the treated side are avoided in the early period so the barbs are not dislodged. Increasing redness or warmth along a thread line, discharge, a visible thread end or persistent numbness warrant an earlier review. The visit is walked through on what to expect at a thread lift visit and recovery on thread lift downtime.
What decides the cost of a thread lift
The fee is set out in writing at consultation, once the plan exists. It depends on:
- the zones treated, such as jowl, mid-face, brow or neck, and how many vectors each needs;
- the number, type and material of threads the assessment calls for;
- whether threads are used alone or combined with an energy protocol or volume restoration;
- how the plan is staged, and the review it includes.
Each driver is explained on thread lift cost factors, and what a written quote contains on how we quote.
How Dr Sin Yong approaches thread lifting
Dr Sin Yong performs thread lifting as the Bliss Lift. He first assesses whether the sag is skin, descended fat pads or lost support. Vectors are planned individually and drawn on the face with you seated upright: an anchor point, a direction, and the number and type of thread for each vector. Material is chosen per vector rather than per face, and cog threads are placed in the subcutaneous plane above the SMAS through a 19–21 G cannula or needle, sometimes with smooth mono threads where skin firmness is part of the plan.
“A thread repositions tissue it can grip. It does not replace volume that is gone, and it does not remove skin that is in excess.”
Dr Sin YongOn what a cog thread can and cannot do
The deciding question is what has moved. If the tissue has slid and the skin and fascia are still reasonably firm, threads can reposition it. If the fascia itself has loosened so the whole lower face hangs, threads have nothing firm to anchor to, and he recommends the VF Lift – Vertical Facelift instead. Where tightening is the real need, Time Freeze Laser LCLR® may be considered. Many faces are assessed for both and leave with one.

WhatsApp Dr Sin YongFrequently Asked Questions
In Singapore, medical devices, which include most aesthetic lasers, energy devices and injectable fillers, must be registered with the Health Sciences Authority (HSA) before they can be supplied; only the lowest-risk class A devices are exempt. Ask which thread will be used and check it on HSA’s medical device register, and check that the clinic holds an MOH licence.
A thread face lift suits mild to moderate descent of the jowls, mid-face or lateral brow in a face that has kept its volume, with skin thick enough to cover the thread. A quick test: if the tissue can be lifted back by hand and looks right there, a thread may hold it. Heavy skin excess, very thin or lean skin, and volume loss mistaken for sagging are not suited.
Fees are not published on this site, because Singapore’s rules on medical advertising do not allow prices to be advertised. The fee for a thread lift depends on the zones treated, such as the jowl, mid-face, brow or neck, the number, type and material of the threads the plan needs, whether threads are combined with an energy protocol, and the review included. A written quote is given after Dr Sin Yong has examined your face and decided whether threads suit it.
A thread face lift can be worth it for a narrow group: tissue that has slid but kept its volume, under skin firm enough to cover a thread. It is poor value for heavy skin excess, lost volume or a loosened fascia, because a thread cannot hold or fill those. Published studies report limited durability for many thread systems, so expectations matter. Where threads do not fit, Dr Sin Yong plans the VF Lift – Vertical Facelift or Time Freeze Laser LCLR®.
Neither is better for every face, because they do different jobs. A thread lift holds descended tissue in a new position mechanically. HIFU places heat points down to the SMAS so collagen contracts and remodels gradually; a 2023 systematic review found it tightened mildly to moderately lax facial skin. Threads suit tissue that has slid; HIFU suits early laxity in a face with fat to spare. In lean faces Dr Sin Yong does not use HIFU; he directs them to the VF Lift – Vertical Facelift to restore lift instead.
Mainly because of the evidence and the way threads are sold. A 2018 systematic review found that most studies showed only very limited durability of the lift, and that the two positive studies were funded by thread makers. Threads are also marketed as a facelift without surgery to faces with skin excess they cannot hold. Used narrowly, for tissue that has slid under firm skin, threads have a place; for heavy laxity, a surgical opinion is the honest route.
Yes. The VF Lift – Vertical Facelift lifts with Volnewmer monopolar radiofrequency and is what Dr Sin Yong recommends where the fascia has loosened too much for threads to anchor. Time Freeze Laser LCLR® tightens with laser heat. Nothing is placed under the skin, so there is no filler to overfill, migrate or form lumps. Neither moves tissue on the day, which is where threads still fit.
Dissolvable threads are made of PDO, PCL or PLLA, absorbable polymers broken down by hydrolysis, and every thread Dr Sin Yong places is dissolvable. No thread lift is risk-free. Recognised complications include a visible or palpable thread, extrusion, infection along the tract, dimpling, nerve irritation and asymmetry. Risk is reduced by choosing suitable skin, placing threads in the subcutaneous plane above the SMAS, sterile technique and review by the doctor who placed them.
Korean thread lift is a marketing name rather than a separate technique. It usually describes absorbable PDO or PCL cog threads of the kind widely made and used in South Korea, sometimes sold under brand or package names. The label says nothing about the material, the vectors or who places the threads. The questions that matter are which thread, in which plane, for which descent, and who reviews you afterwards.
It depends on whether the problem is one threads can address. A thread grips tissue and repositions it, so it suits mild to moderate descent of the jowls, mid-face or lateral brow where volume is reasonably preserved and the skin is thick enough to cover the thread. It does not remove skin excess, add volume or change skin quality. Dr Sin Yong examines the face upright and in animation before deciding whether threads, energy or volume restoration fits.
There is no fixed duration. The barbs hold tissue while the thread keeps its strength, and the collagen capsule laid down around it contributes some support after the polymer has been broken down. How long the effect remains depends on the material, with PDO resorbing fastest, PLLA more slowly and PCL slowest; on how much descent there was to begin with; on skin thickness; and on the fact that the face keeps ageing around the threads. Maintenance is planned from what review shows rather than on a calendar.
The entry points and the path of each thread are infiltrated with local anaesthetic before any thread is placed, so the procedure itself is felt mainly as pressure and pulling. Afterwards, tightness on wide mouth opening, tenderness at the entry points and an awareness of the threads are expected while the tissue settles. Persistent or increasing pain is a reason for review rather than something to wait out.
PDO (polydioxanone) and PCL (polycaprolactone) are both absorbable polymers broken down by hydrolysis in the tissue. PDO is the same material as absorbable surgical suture and resorbs the fastest of the common thread materials; PCL resorbs the slowest, so it remains as a scaffold for collagen deposition for longer. Both can be made as mono, screw or cog threads. Which material suits a given zone is decided by skin thickness and the plan, not by the material alone.
No. A thread repositions tissue it can grip; it cannot remove skin. Where descent is mild to moderate and skin quality is reasonable, threads can hold a jowl or cheek in a repositioned place. Where there is heavy skin excess, moving that skin with a thread produces bunching, and a surgical facelift, which excises the excess, is the appropriate discussion. The assessment decides which category a face falls into.
Yes, and they are often planned together because they work by different mechanisms in different planes. Threads hold tissue mechanically in the subcutaneous layer. HIFU creates thermal coagulation points at the SMAS and deep dermis; monopolar radiofrequency heats the dermis in bulk. Neither energy treatment moves tissue on the day, and no thread heats it. The order and spacing of combined treatments are decided at consultation for each face.
It varies between people and zones. Swelling, bruising along the vectors and tightness on opening the mouth are common early on, so some people plan quieter time before social or work commitments while others return sooner. Wide mouth opening, facial massage, dental work and sleeping on the treated side are avoided in the early period so the barbs are not dislodged. What to expect for your plan is explained before treatment.
In the early period, yes. If a thread end extrudes at the entry point, or a tract becomes infected, the thread can be located and withdrawn or trimmed. Because the materials are absorbable, a thread that is simply no longer wanted is left to resorb by hydrolysis rather than removed. Removal later becomes harder as the fibrous capsule forms around the thread, which is one reason concerns should be raised at review rather than deferred.
