PDO threads are often grouped into three configurations: smooth or mono threads, twisted or screw threads, and barbed or cog threads. These names describe their design—not three interchangeable ways to achieve the same result.
The main distinction is between encouraging a tissue response and physically engaging tissue for support. Smooth threads have little mechanical lifting ability. Barbed threads can engage tissue to provide temporary support and repositioning. Screw threads have a coiled design, but should not be viewed as a predictable replacement for facial volume treatments.
At Elite Laser Center & Med Spa in Stony Brook, a consultation helps determine whether PDO threads, another treatment, or no procedure is the best fit for your goals.
What Are PDO Threads?
PDO stands for polydioxanone, an absorbable material used in medical sutures. Aesthetic threads are placed beneath the skin, where they gradually break down.
Placement can produce a healing response, including collagen formation around the material. That biological response is different from the mechanical support provided by a lifting thread.
Neither process guarantees a particular cosmetic result. PDO threads cannot remove excess skin or reproduce a surgical facelift.
The Three Common Types of PDO Threads
Smooth or Mono Threads
Mono threads are smooth filaments without the barbs used to grip tissue. They are generally discussed for skin-quality concerns rather than substantial lifting.
A provider may consider them when the goal is a modest change in skin support or texture. However, thin or crepey skin does not automatically make someone a suitable candidate.
Ask what improvement is realistic for the proposed area and what evidence supports that recommendation. “Collagen stimulation” should not be treated as a promise of a visible lift.
Screw or Twisted Threads
Screw threads use a coiled configuration, sometimes incorporating intertwined filaments. They are described in clinical guidance for localized support or subtle fullness.
Claims about volume need careful interpretation. A coiled thread is not equivalent to a measured amount of filler, and a hollow cheek or temple should not automatically be treated with threads.
If volume loss is your main concern, ask your provider to compare threads with other options. The anatomy of the area, the specific product, and the limits of the evidence matter.
Barbed or Cog Threads
Cog threads have projections designed to engage tissue. They are used when the proposed goal is temporary support or repositioning rather than skin-quality improvement alone.
They may be considered for selected patients with early tissue descent, but the amount of change depends on much more than the presence of barbs.
Ask which product and design your provider recommends, why it suits your anatomy, and how the expected result compares with alternatives.
Mono, Screw and Cog Threads at a Glance
| Thread configuration | Main design feature | General treatment discussion | Important limitation |
|---|---|---|---|
| Smooth / mono | Unbarbed filament | Skin-quality response and subtle support | Little mechanical lifting ability |
| Screw / twisted | Coiled filament design | Localized support or subtle fullness | Not a predictable substitute for filler |
| Barbed / cog | Projections that engage tissue | Temporary support and repositioning | Cannot remove excess skin or match a facelift |
These are broad categories, not a treatment menu for every patient. Confirm which configurations are available and appropriate at your consultation.
Is Skin Laxity the Same as Volume Loss?
A softer jawline, hollow cheek, and rough skin texture can look like parts of the same problem, but they may call for different approaches.
Threads are generally discussed for tissue support. Dermal fillers and other injectable treatments may be considered for different concerns, including volume loss or expression lines. Skin-tightening treatments work differently again.
Start by explaining what bothers you rather than choosing a device or product first. A useful consultation compares the available options and their risks.
Who May Be a Candidate for PDO Threads?
Elite's PDO thread treatment page describes treatment for selected adults seeking improvement in mild to moderate laxity.
Significant excess skin or a desire for a dramatic lift may lead to a different recommendation, including a surgical consultation.
Bring details of your medical history, medications, supplements, previous procedures, and any permanent or absorbable implants in the proposed area. Explain your history of infections, reactions, or healing problems.
Do not stop prescribed medication on your own. Ask your treating provider whether preparation requires coordination with your usual clinician.
What Does Treatment Involve?
The appointment begins with assessment and discussion of the proposed plan. The area is prepared, and local anesthetic may be used. Threads are placed beneath the skin using needles or cannulas, depending on the product and technique.
Pressure, pulling, or discomfort may occur despite numbing. Treatment duration varies, so ask how much time to reserve.
Before proceeding, confirm the product name, intended treatment area, expected benefit, recovery plan, total price, and arrangements for follow-up.
Recovery: Plan for Visible Healing
A thread procedure involves less recovery than a surgical facelift, but it is not a no-downtime promise.
Swelling, bruising, tenderness, tightness, and temporary contour irregularities can occur. Early swelling may also affect how much improvement you think you see.
Ask for written instructions about sleeping position, pressure on the area, skincare, exercise, facial movements, and other treatments. Follow the guidance for your actual procedure rather than a universal online timeline.
Allow flexibility around important events. Do not assume you will be ready for photographs or strenuous activity immediately afterward.
Risks Worth Discussing Before Treatment
Thread-lifting studies report complications including swelling, bruising, dimpling, visible or palpable threads, altered sensation, infection, and extrusion through the skin. Asymmetry or dissatisfaction may also require follow-up.
Published complication rates vary with the products, techniques, patients, and definitions used. A percentage pooled across studies is not your personal risk estimate or Elite's complication rate.
Ask how the provider evaluates and manages problems. Contact them promptly for worsening pain, increasing redness or swelling, drainage, fever, or a thread becoming exposed. Do not pull, trim, or try to reposition a thread yourself.
How Long Do PDO Thread Results Last?
The material's absorption time and the duration of a visible result are different questions. Both depend on the product and treatment circumstances.
No fixed duration should be promised. Research on long-term benefits remains limited, and more threads do not necessarily mean a better or longer-lasting outcome.
A small randomized clinical trial published in 2025 found that increasing thread quantity did not significantly improve sustained lifting or satisfaction during its follow-up. That study does not settle every question, but it supports asking for evidence rather than assuming a larger treatment plan is better.
Can PDO Threads Be Combined With Other Treatments?
Sometimes different procedures are considered within a broader plan, but combining them requires individual assessment.
Tell every treating provider about existing threads before arranging fillers, RF treatments, or other facial procedures. Do not assume a combination is appropriate or that it can be performed at the same visit.
Ask which concern each procedure addresses, what additional benefit is expected, and whether the extra treatment introduces additional risk.

Who will assess a complication, and are follow-up costs included?
Frequently Asked Questions
Which PDO thread is best?
There is no single best configuration. The recommendation depends on the treatment goal, anatomy, product, and provider's assessment.
Do smooth threads lift the face?
Smooth threads do not engage tissue like barbed threads. They should not be presented as producing the same mechanical lifting effect.
Can screw threads replace filler?
Not reliably. They are different products with different mechanisms, and major volume loss requires its own assessment.
Are PDO threads permanent?
No. PDO is absorbable, and cosmetic effects are temporary. A provider should explain product-specific expectations without guaranteeing longevity.
Are all PDO thread products cleared for the same uses?
No blanket claim should be made. Ask about the exact product, its labeling, and the proposed use rather than assuming that the material name establishes regulatory clearance.
