Thread Lift Longevity: How Long Do PDO Threads Last?

4 days ago

9 min read

Most thread lift results last somewhere between one and three years, but the threads themselves are gone much sooner. PDO threads dissolve in roughly four to eight months, and what you keep after that depends on collagen, tissue quality and the technique used. Some people hold a subtle lift for a year or more. Others see most of the change fade within months. Here is what the research shows, what changes the outcome, and how to judge a realistic promise from an inflated one.

TL;DR

Patient-information sources from medical and plastic surgery bodies put thread lift results at roughly one to three years. Some studies report much shorter results.
PDO threads are absorbable. They soften within a month or two and are generally fully dissolved by about six to eight months.
The visible lift can outlast the thread because collagen and tissue remodelling continue, but the evidence on how much is mixed.
Skin laxity, thread type, placement technique and your own biology shape how long it lasts. More threads do not automatically mean a longer lift.
A thread lift is a modest, temporary option. A surgical facelift lasts substantially longer.

How long thread lift results last

The most common answer from clinical sources is one to three years. Cleveland Clinic describes thread lift results as temporary, usually lasting one to three years, as the body gradually dissolves and absorbs the threads. The British College of Aesthetic Medicine gives the same range and adds that it depends on the patient’s concerns and the threads used. The American Society of Plastic Surgeons also says one to three years, and notes that a surgical facelift can last substantially longer.

That range is wide on purpose. It covers different thread materials, different faces and different expectations. A 2020 evidence-based review found that reported longevity varied from months to years. It put more weight on technique and patient selection than on thread type, and it called for better long-term, standardized studies.

So treat “one to three years” as the upper part of a realistic window, not a guarantee. If you are 38 with mild early jowling, you are in a very different position from someone with significant skin laxity.

Why the numbers online disagree

If you have searched this topic, you have seen claims ranging from a few weeks to three years. Part of the gap is what is being measured:

The thread itself: how long the material remains in the tissue.
The mechanical lift: how long the thread physically holds tissue in a new position.
The overall appearance: how long you still look better than before, including the effect of collagen and swelling.

The early look right after a procedure also includes swelling, which settles. Someone who judges the result at three weeks and someone who judges it at twelve months are describing different things. A fair assessment compares photos taken in the same light, at the same angle, at set intervals.

Do PDO threads dissolve?

Yes. PDO (polydioxanone) is an absorbable material. A 2024 review in Cosmetics notes that PDO has strong tensile strength among absorbable threads and takes more than six months to dissolve. The same review describes a typical timeline: the thread softens substantially within one or two months, and it is generally completely dissolved about six to eight months after insertion.

Other sources give slightly shorter figures, which is normal because thread thickness, design and tissue all vary:

The American Society of Plastic Surgeons says PDO sutures remain in place about four to six months and then slowly dissolve, while visible results may continue for a year or more.
A 2025 randomized trial says PDO is reabsorbed through hydrolysis in about four to six months.
A rat study found PDO threads visible in tissue sections for up to six months and fully absorbed within eight. Animal data is only a guide, but it fits the human timelines.

A practical reading: by month six to eight, no thread should remain. Anything you still see in the mirror after that comes from your own tissue.

Why the result can outlast the thread

It seems contradictory that a lift can last two years when the thread is gone in under one. The explanation is the body’s response. The thread gives temporary mechanical support, while the tissue reacts to it by forming collagen and fibrous tissue, and that response may continue as the material weakens.

A few findings help here:

A 2024 prospective pilot study notes that PDO threads generally dissolve within about six months, while collagen production and tissue remodelling may support the improvement afterward. It followed patients for 24 months after combined filler and thread treatment. Its authors credited the prolonged improvement to ongoing collagen production and tissue support, not to threads that were still intact.
In the rat study, collagen formation depended on the surface area of the thread, and a cavern-type PDO thread produced more new collagen than simpler designs.

Two cautions apply. First, the evidence is mixed on how clinically meaningful the leftover effect is. A thread dissolving does not make your face change overnight, and it does not guarantee a durable lift either. Second, the 24-month pilot involved a combination of treatments, so it cannot be read as “threads alone last two years.”

When results fade faster than expected

Honest longevity advice has to include the less flattering studies.

A commentary on a 160-patient study of dissolvable threads reported that the initial lifting or contouring improvements were absent at one year. That is one study, and it contrasts with the broader one-to-three-year estimates, but it is a reminder that the low end of the range is real.
A 2025 randomized clinical trial found that early changes in volume and tissue displacement had diminished by 60 days. Using more threads did not significantly improve sustained lifting or satisfaction during the study period.
A 2021 clinical study of absorbable barbed threads found that longer 23 cm threads were slightly better than 12 cm ones. It also noted that absorbable threads generally give less durable visible lifting than non-absorbable ones.

One 2017 Japanese study of insoluble (non-absorbable) threads found the rejuvenating effect dropped in the first year and then trended upward. The authors themselves asked for multicentre confirmation, and it concerns a different type of thread, so it should not be applied to PDO.

The takeaway is not that threads do nothing. It is that the lift is subtle, that most of the gain is early, and that the more dramatic the promise, the more sceptical you should be.

What affects how long your lift lasts

The 2024 Cosmetics review ties longevity to patient selection, fixation points, material, thread thickness, cog shape and number, insertion depth, lifting vectors and expiration dates of the product. In plain terms, these are the factors that matter to you.

Your skin and tissue

Threads work best on mild to moderate sagging. Heavy skin, significant volume loss or deep folds ask more of a thread than it can give. Good candidate selection is the single most important variable, and it is the part a patient can test by asking an honest question: “Will this actually help my face, or would something else serve me better?”

Thread design and placement

Thread thickness, whether it has barbs or cogs, how deep it sits, and the direction it pulls all influence the result. This is why the injector’s training matters more than the brand name on the packet. The same principle shows up in other injectables: our piece on why technique, not brand, drives safer filler results makes the case for fillers, and it applies here too.

Number of threads

It is tempting to think more threads means a longer lift. The 2025 trial found no significant sustained benefit from adding more over the study period. Paying for volume of threads is not the same as paying for a plan.

Your lifestyle and biology

Age, sun exposure, smoking, weight changes and how your skin makes collagen all play a part. Not all of this can be controlled, and no clinic can predict it precisely. That is another reason published ranges are wide.

Combining treatments

The 2020 review observed that, in practice, combinations of treatments work over time rather than any single procedure. Threads are often one piece of a plan that may include injectables for volume, skin treatments for texture, and good daily sun protection.

Thread lift versus other options

The fair comparison is by purpose, not by which one wins.

Option	What it does best	Typical timeframe
PDO threads	Mild, subtle lift and skin support in selected areas	Threads dissolve in months; visible effect commonly cited at one to three years
Dermal filler	Restores volume and softens folds	Varies by product and area
Skin boosters and resurfacing	Improve skin quality and texture, not position	Depends on the treatment and course
Surgical facelift	Repositions deeper tissue for a larger change	Substantially longer than threads, per ASPS

The only figures in this table that come from the sources above are the thread and surgical facelift lines. For fillers, the answer depends on the product and where it goes. Our guide to non-surgical facelift options and what they cost walks through where each approach fits.

Getting the most from your threads

You cannot make a thread last longer than the material allows, but you can protect the outcome.

Follow the aftercare you are given. Our pre and post procedure guidelines set out what to do before and after treatment.
Know the recovery timeline and red flags. Swelling, tightness and minor bruising are expected early on. Our nurse practitioner’s PDO thread recovery timeline explains what is normal and what needs a call to your clinic.
Protect your skin from the sun. Collagen you have built is worth protecting, and sun damage works against it.
Judge results fairly. Take photos before, then compare at a few set intervals rather than relying on memory.
Plan the next step ahead of time. Ask whether you would repeat threads, add filler, or choose a different treatment when the effect fades.

Our perspective

We are a nurse practitioner-led clinic, and we would rather lose a sale than set the wrong expectation. When someone asks us about thread lift longevity, the honest answer is that the thread is a temporary scaffold, and the lasting part is what your own skin does in response. That response varies from person to person.

We tend to start with the face in front of us, not the treatment on the menu. For some people, threads suit a mild lifting goal. For others, volume, skin quality or a different approach will serve them better, and we say so, in line with our commitment to honest recommendations that fit your goals and your budget. We also prefer natural-looking change over a dramatic one. If a plan promises a fixed number of years, it is promising more than the research supports.

Our view is simple: choose the treatment for the result you want, understand how long it realistically lasts, and have a clear plan for maintaining it.

FAQ

How long do PDO threads last?

The threads themselves usually dissolve in about four to eight months, depending on the source and the thread design. The visible result is commonly quoted at one to three years by medical and plastic surgery bodies. Some studies report that the effect fades much sooner, so expect individual variation.

Do threads dissolve completely?

PDO threads are absorbable, and the body breaks them down by hydrolysis. Reviews describe them as generally fully dissolved around six to eight months after insertion. Any lasting change after that comes from collagen and tissue remodelling, not from the thread.

Will more threads make the lift last longer?

Not necessarily. A 2025 randomized trial found that using more PDO threads did not significantly improve sustained lifting or satisfaction during the study period. Placement, thread design and choosing the right candidate matter more than the count.

How does a thread lift compare with a facelift for longevity?

The American Society of Plastic Surgeons says a thread lift generally lasts one to three years, while a surgical facelift can last substantially longer. Threads suit people with mild sagging who want a less invasive option. If you want a larger or longer-lasting change, ask for an honest assessment of whether threads are the right tool.
