Neo Thread Mono PDO is a polydioxanone threads used for the thread lifting of face and neck. Polydioxanone (PDO) is a flexible polymer, which remains intact in the injection point up to 6 months. Threads created based on PDO exhibit multiple effects: their subcutaneous injection initiates skin self-regeneration by increasing collagen synthesis and improving blood microcirculation. As a result of the application of polydioxanone threads the significant lifting effect is observed accompanied by wrinkles elimination, small skin imperfections diminishment, as well as elasticity improvement.

One PDO filament, coiled rather than straight
NEO Screw Single Thread is a single polydioxanone filament wound into a spiral around its needle, rather than lying straight as a mono thread does.
The coil is the entire difference, and it is a geometric one rather than a material one. Winding a filament into a spiral fits more thread length into the same track — so a coiled thread delivers more PDO, and therefore more collagen stimulus, per insertion than a straight filament of the same gauge and length. It also distributes that material through the tissue column rather than along a single line.
It does not lift. The surface is smooth; coiling changes the shape, not the grip. Repositioning tissue requires barbs, which this product does not have.
A spiral packs more filament length into a given insertion than a straight strand does.
The coil distributes material through the tissue column rather than along a flat line.
The full gauge range, 23G down to 31G — matching the mono line size for size.

Why practitioners stock NEO Screw Single Thread
The coil fits more filament into the same track, so you get a greater collagen response without an extra needle pass.
More material than a mono, less bulk than two parallel filaments. Useful where a mono mesh under-delivers but twin threads would be too much.
Twenty-three combinations from 23G × 60 mm down to 31G × 12 mm — the same spread as the mono line, so you can switch format without changing size.
Priced alongside the mono line, so the extra material per pass costs nothing in unit price.
Treatment areas
Areas commonly treated with coiled PDO threads. All are skin-quality applications — a smooth filament cannot reposition tissue, whatever shape it is wound into.
Where you want a strong collagen response in a defined area rather than light coverage across a broad one. This is what the coil format is best suited to, and the clearest reason to choose it over a mono.
Building dermal thickness where skin has thinned, using fewer placements than a mono mesh would require. The 26G and 27G sizes cover this zone.
Crepey texture and loss of density, where the longer 25G needles cover more ground per pass. Skin here is thin — place deeper than you would on the cheek.
Fine lines around the mouth, treated with the 30G and 31G short needles. Very superficial work in thin skin, where the coil’s extra bulk needs respecting.
PDO threads are sterile implantable medical devices. Which applications are permitted, and what training is required, is determined by the regulatory framework where you practise. Korea Filler Experts supplies the product; nothing here is a recommendation to treat any medical condition, and nothing here substitutes for hands-on training in thread technique.

Checking the pack
- The model code matches your order. Screw codes begin with S; mono codes begin with M and are otherwise identical, so check the first letter.
- Each blister is intact and dry. A breached sterile barrier makes that unit waste.
- The expiry date is clear. PDO hydrolyses with moisture.
- The pack holds 20 pieces.
The coil is pre-formed. Do not attempt to straighten or re-wind it — the spiral is what you are buying.
What each component does
Screw versus mono — choosing between them
These two products share a size range, a price point and a mechanism. The only difference is whether the filament is coiled or straight, and it has two practical consequences.
- More material per track. A spiral fits more filament length into a given insertion, so the collagen stimulus along that track is greater.
- Different distribution. A straight thread deposits material along a line; a coil spreads it through the surrounding tissue column.
So: mono when you want an even, fine mesh built from many light placements, or when the skin is thin enough that bulk matters. Screw when you want more response from the same number of passes, or when the target is a defined zone rather than a broad sheet.
Many practitioners stock both and use them together — mono to cover area, screw to concentrate response where it is most needed.
Reading the specifications
- 23G to 31G — needle diameter; higher number means thinner. 31G is the finest in the range.
- Needle vs thread length — the filament extends beyond the needle so it stays in tissue as it withdraws. A 60 mm needle carries 90 mm of thread, and the coil means more of it occupies that track than a straight strand would.
- USP 3-0 to 7-0 — filament thickness on the standard suture scale, where more zeros means thinner. Roughly 0.05–0.07 mm at 7-0 and 0.20–0.25 mm at 3-0 on the USP range for synthetic absorbable sutures.
How to use NEO Screw Single Thread
Reference information for trained practitioners. Thread insertion requires specific training in facial anatomy and technique; this is not a procedure to attempt from a product page.
Step by step
-
Plan placement with the patient upright
Mark the treatment zone before they lie down. Plan fewer placements than you would with mono threads — each coil carries more material.
-
Prepare the field
Cleanse and disinfect thoroughly. Threads are implanted and remain in situ for months, so antisepsis matters more than for an injectable that disperses.
-
Anaesthetise as needed
Topical anaesthetic is usually sufficient at the finer gauges; entry points for 23G and 25G needles may warrant a small amount of local.
-
Insert along the planned track
Enter at a shallow angle and advance in the correct plane — dermal or immediately subdermal depending on zone. A coiled thread occupies more space than a straight one, so err slightly deeper.
-
Withdraw the needle, leave the thread
Hold the thread hub steady and withdraw the needle along the same track. The filament stays behind, retaining its coil.
-
Trim and palpate
Trim any protruding thread flush at skin level, then palpate the track for ridging before the next pass.
Administration notes
Place fewer than you would mono threads. The coil delivers more material per insertion, so a mono-density mesh of screw threads over-treats the area. This is the usual error when practitioners switch format.
Go slightly deeper than with a mono. A coiled filament has more bulk, so the depth that sits invisibly for a straight strand can ridge with a spiral — particularly in thin skin.
- Single use. Never re-sterilise or reuse a thread or its needle.
- Do not place across active infection, inflamed skin, or recently placed filler.
- Keep clear of major vessels and nerves — a sharp needle gives no tactile warning.
- Dispose of needles into a sharps container per local clinical waste requirements.
After treatment
- Mild bruising, swelling and tenderness along the tracks are expected and usually settle within a week
- Avoid extreme facial expression and vigorous massage for about two weeks
- No saunas, steam rooms or strenuous exercise for 48 hours
- Sleep on the back where practical for the first few nights
- Defer dental work and facial treatments for two weeks
- Any spreading redness, increasing pain or discharge needs reviewing promptly
Storing and handling NEO Screw Single Thread
Store at room temperature in a dry place, away from direct sunlight. No refrigeration and no cold chain.
Each thread is individually sealed and sterile. Do not use any unit whose blister is open, torn, damp or damaged. Never re-sterilise — autoclaving destroys PDO.
The spiral is formed during manufacture. Do not straighten or re-wind it, and avoid dragging the thread against packaging — a disturbed coil no longer distributes material as designed.
Single use only. Do not reuse, re-sterilise or repackage. Dispose of used needles into a sharps container and unused product as clinical waste in line with local requirements.
What's included
Each pack contains one size only — threads are not mixed within a pack. Screw codes begin with S; the equivalent mono codes begin with M. Antiseptic, anaesthetic, marking pen and sharps disposal are not supplied.
NEO Screw Single Thread — frequently asked questions
What is a screw thread?
A single polydioxanone filament wound into a spiral around its needle, rather than lying straight. The surface is smooth — the coil is a shape, not a texture, and there are no barbs.
How is it different from your mono thread?
Only in that the filament is coiled rather than straight. Same material, same mechanism, same size range and the same price.
The coil fits more filament length into a given track, so you get more collagen stimulus per insertion, distributed through the tissue column rather than along a line.
Which should I choose — mono or screw?
Mono for an even fine mesh built from many light placements, or where skin is thin enough that bulk matters. Screw where you want more response from the same number of passes, or where the target is a defined zone rather than a broad sheet.
Many clinics stock both — mono to cover area, screw to concentrate response where it is most needed.
Will a screw thread lift?
No. Coiling changes the thread’s shape, not its grip — the surface is still smooth, so there is nothing to engage tissue with.
This is worth saying plainly because “screw” sounds like an anchoring mechanism and is often marketed as one. It is not. Repositioning requires barbs, which means our Cog Cannula or Combi Cog.
How many should I place?
Fewer than you would mono threads — the coil delivers more material per insertion, so a mono-density mesh over-treats. Reducing your usual mono count by about a third is a reasonable starting point.
Which gauge should I choose?
Match the needle to the tissue. The 30G and 31G short needles suit periorbital and perioral skin; 27G to 29G covers most general facial work; 25G and 26G with longer needles suit the neck and jawline; 23G is for body work or dense tissue where a fine needle would deflect.
What does "USP 5-0" mean?
It is the filament’s thickness on the standard suture scale, and it runs backwards from what you might expect: more zeros means thinner. A 7-0 thread is much finer than a 3-0.
It is separate from the needle gauge, though the two generally track together — a fine needle carries a fine thread.
How long does the effect last?
The PDO hydrolyses over roughly six months. The collagen laid down around it persists beyond that, so the clinical effect outlasts the material.
Duration varies by patient, density and skin condition. Review at six to nine months and plan from what you see rather than promising a figure.
Do they need refrigeration?
No. Room temperature, dry, out of direct sunlight — no cold chain to manage, which makes threads much simpler to stock than injectables.
Who can buy and use these?
Threads are sterile implantable medical devices for use by trained healthcare professionals. Insertion requires specific training in facial anatomy and thread technique. We supply to practitioners qualified to perform the procedure in their jurisdiction, and do not sell to consumers.
