Both are used to raise and refine the nose without surgery, and they behave very differently. Dr Sin Yong at IN Eternity Clinic on Orchard Road compares how each works, its risks, and who each suits.
WhatsApp to Enquire →Key facts ↓A nose thread lift places absorbable PDO threads along the bridge and sometimes into the tip, adding a defined line and some tip support. Nose filler adds volume on the bone and cartilage to raise a flat bridge or project the tip. Threads suit definition; filler suits height. Many noses need one, some both, and neither narrows the nose.
Both treatments are sold as “non-surgical rhinoplasty”, and both can make a nose look higher and more defined in profile. That is where the similarity ends. Threads add a structural line and support. Filler adds material. The question is not which is better in general, but which does what your nose needs.
At IN Eternity Clinic, Dr Sin Yong starts with the nose rather than the product: how high the bridge sits between the eyes, how thick the skin is, how well the tip is supported, whether the nose is straight, and whether there has been surgery or earlier injections. The answers usually point clearly to threads, filler, both, or neither.
Many East Asian noses share a few features that shape this choice: a low bridge between the eyes, a tip with softer cartilage support, and skin that is thicker over the tip than over the bridge. A low upper bridge is mainly a height problem, which filler addresses. A soft, droopy tip is mainly a support problem, which threads address. Thick tip skin can hide the definition threads create, while thin bridge skin can show a thread or an edge of filler. Reading those details is what turns a general comparison into a plan for one nose.
A nose thread lift uses fine polydioxanone (PDO) threads, the same absorbable material used for surgical sutures. After numbing, the threads are passed through a small entry point, usually at the tip, and laid along the bridge in a plane close to the underlying support. Barbed threads can also be placed vertically through the columella towards the tip to give it more projection.
The threads support the soft tissue from the moment they are placed, which gives a sharper, straighter line along the bridge and a slightly lifted tip. Over the next six to eight months the PDO is absorbed, and a thin layer of collagen forms along each track. What lasts is that tissue response, not the thread itself, so the effect softens over months and is often maintained with a top-up.
Published series combining PDO threads with filler in the nose describe threads as most useful for tip support and definition, with filler providing height where needed. The nose thread lift page sets out how it is done at IN Eternity Clinic, and the HIKO nose thread lift article explains that branded technique.
“Threads give a line. Filler gives height. I decide which your nose needs before deciding how much.”
Nose filler raises the bridge or projects the tip by adding volume. It is placed deep, on the bone of the upper bridge and close to the cartilage lower down, in small amounts so that the profile changes without widening the nose. The result is visible at once, although swelling can blur it for a few days.
The product matters. Soft hyaluronic acid (HA) fillers can spread sideways on a mobile, thin-skinned structure and are dissolvable, which is their main advantage. Firmer collagen-stimulating fillers such as calcium hydroxylapatite and polycaprolactone hold projection with less spread, and studies of calcium hydroxylapatite for nasal contouring have reported durable profile changes. At IN Eternity Clinic, Dr Sin Yong usually uses calcium hydroxylapatite or polycaprolactone for the nose; HA remains an option where reversibility is the priority.
More detail on technique and products is on the nose filler page and in the nose filler guide.
| Nose thread lift | Nose filler | |
|---|---|---|
| What it adds | A defined line and tip support | Height and projection |
| Suits | Thin to medium skin, soft tip, modest height wanted | Low bridge, flat profile, small dips or a bump to camouflage |
| How long | Threads absorb over months; effect often softens within a year | Varies by product; collagen stimulators usually last longer than HA |
| Can it be undone? | A thread can usually be removed | HA can be dissolved; CaHA and PCL cannot |
| Key risk | Visible thread, extrusion, infection | Vascular blockage, skin damage, rarely vision loss |
In practice the two are often combined. Threads can give the tip support that filler alone tends to lack, while a small amount of filler on the upper bridge gives height that threads cannot. Combining them can mean less of each, which is part of the reason for doing it.
The most serious risk in the nose belongs to filler. The arteries of the nose connect with those that supply the eye, and filler that enters or compresses a vessel can starve the skin of blood or, rarely, travel towards the eye. Reviews of filler-related blindness consistently list the nose among the highest-risk areas. Risk is reduced by placing product deep on the bone, injecting small amounts slowly, and being ready to act immediately if the skin blanches or the patient reports pain or visual change.
Thread risks are different. The commonest are a thread that can be felt or seen under thin skin, a thread end that works its way out at the tip, infection along the track, and a slight sideways drift of the bridge. Most are managed by removing the thread and letting the tissue settle. Thread risks rise with too many threads, thin or tight skin, and a tip that has had surgery.
For both, a nose that has had surgical rhinoplasty, especially with an implant, needs particular caution, because scar tissue and an altered blood supply change how the tissue behaves. Sometimes the honest advice is to see a rhinoplasty specialist instead.
Both are done under numbing, and both leave the nose swollen and tender for a few days. Threads tend to cause more tip tenderness and a stiff feeling when smiling; filler causes more pressure along the bridge. Glasses resting on the bridge, firm pressure, saunas and strenuous exercise are avoided for the first week or two. The final shape is judged after about two weeks, once swelling has gone.
Threads usually suit someone with reasonable bridge height who wants a crisper line and a lifted tip, and who accepts that the effect is temporary. Filler usually suits someone whose main complaint is a low bridge or flat profile. Neither suits someone who wants a narrower or shorter nose, or whose concern is breathing; for those, surgery is the appropriate route. The non-surgical rhinoplasty guide covers this in more depth.
Whichever you choose, a review at about two weeks is part of the plan. Swelling hides small asymmetries at first, and a modest adjustment, such as a little more filler at one point or removing a thread that can be felt, is easier to decide once the tissue has settled. If filler from elsewhere is already present, an ultrasound assessment on the filler correction page explains how its type and position are checked before anything is added.
Collagen-stimulating fillers such as calcium hydroxylapatite and polycaprolactone usually last longer than a nose thread lift. PDO threads are absorbed over six to eight months, and the supporting effect often softens within a year. Hyaluronic acid filler in the nose varies. How long any result lasts also depends on skin thickness and how much the nose moves.
They carry different risks. Filler in the nose carries a rare but serious risk of blocking a blood vessel, which can damage skin and, very rarely, affect vision. Threads avoid most of that risk but can become visible, work their way out at the tip or become infected. Both are done only after the anatomy has been assessed and the risks discussed.
Yes, and they are often combined. Threads give tip support and a defined line, and a small amount of filler on the upper bridge adds height. Combining them can mean using less of each. Whether to do both on the same day or in stages depends on your anatomy and how much change you want.
Sometimes, but with caution. Previous surgery, especially with an implant, changes the blood supply and leaves scar tissue, which raises the risk of infection, extrusion and vascular problems. Dr Sin Yong reviews what was done and examines the nose before advising, and in some cases recommends returning to a rhinoplasty specialist instead.
No. Both add height and definition rather than taking anything away. A higher bridge can make the nose look slimmer from the front, but neither treatment reduces the width of the bones or nostrils, shortens a long nose or removes a large hump. Those changes need surgical rhinoplasty.
Hyaluronic acid filler can be dissolved with hyaluronidase, a prescription medicine. Calcium hydroxylapatite and polycaprolactone cannot be dissolved this way, which is why the amount used is conservative and the plan is discussed carefully first. If you do not know which filler you had before, an ultrasound scan can help identify it.
The cost depends on the number of threads or the amount and type of filler, whether the bridge and tip are both treated, and whether the treatments are combined or staged.
