How Long Do Thread Lifts Last? A Plain Guide to PDO, PLLA, and PCL
The thread dissolves long before the result does — which is the part most explanations skip.
A thread lift does two things: it physically repositions soft tissue for an immediate lift, and it stimulates new collagen as the thread dissolves, so part of the result outlasts the material itself. The three common threads differ mainly in how long they last. PDO threads dissolve fastest — material gone in roughly 6–8 months, with visible lift often lasting around a year. PLLA threads last longer and stimulate more collagen, with results commonly around two years. PCL threads last longest, often two to three years. All figures are ranges — longevity varies with the individual, the number of threads, and technique, and your clinic advises what suits you.
Thread lifts are one of the most searched-for treatments in Korean aesthetics, and also one of the most misunderstood. The confusion usually comes down to a single question that sounds simple: how long does it last?
The honest answer has two parts, because a thread lift does two different things — and they don’t last the same amount of time.
What does a thread lift actually do?
Two things at once.
First, the mechanical lift. Fine threads, usually with tiny barbs or cogs, are placed under the skin to physically catch and reposition soft tissue — along the jawline, cheeks, or neck. That’s the immediate result you see on the day.
Second, and more quietly, collagen stimulation. As the thread slowly dissolves over months, it prompts a controlled response in the skin that stimulates new collagen where the thread sat. This is the part people miss: the thread is temporary, but the collagen it leaves behind is what makes the result outlast the material. So a thread lift isn’t really “a thread holding your face up.” It’s a lift plus a gradual firming that continues after the thread is gone.
So how long does each type last?
This is where the three common thread materials differ — and it’s the difference worth understanding before you choose.
- PDO (polydioxanone) dissolves fastest. The material is typically gone in around 6–8 months, though the visible lift often persists somewhat longer — commonly cited at about a year — thanks to the collagen it leaves behind. It’s the gentlest collagen stimulator of the three.
- PLLA (poly-L-lactic acid) lasts longer and stimulates more collagen. The thread persists around 12–18 months, and results are commonly described as lasting about two years.
- PCL (polycaprolactone) lasts longest. It sustains and stimulates collagen over roughly 24 months or more, with results often cited at two to three years.
A fair word of caution on all of these numbers: they’re ranges, not promises. How long your result lasts depends on your skin, your age, how many threads are used and where, and the skill of the placement. Which is exactly why the right thread for you is a conversation with the clinic, not a number from an article.
What does recovery really look like?
Gentler than most people expect — this is much of the appeal.
Mild swelling, some bruising, or a tight, slightly pulled feeling is normal for the first several days. Most people are back to ordinary social life within two to three days. Clinics generally suggest avoiding strenuous exercise, big or exaggerated facial expressions, and sleeping on your side for around two weeks, so the threads settle undisturbed. Your clinic will tailor the aftercare to you.
Because the downtime is measured in days, thread lifts sit well inside a normal Korea trip — which is part of why they belong to The Lift in our curations, and why they’re worth planning early in your visit rather than the day before you fly. (How Many Days Should You Stay in Korea for Treatment? goes into the sequencing.)
The one expectation that matters most
If there’s a single thing that decides whether someone is happy with a thread lift, it isn’t the thread type. It’s the expectation.
A thread lift is a refinement — a subtle lift and a firming, with little downtime. It is not a facelift, and it won’t do what surgery does. Understood on its own terms, it’s one of the most rewarding non-surgical treatments there is. Expecting it to replace surgery is where disappointment begins.
If you’re weighing whether a thread lift suits your face and your goal — or whether something else fits better — that’s the kind of honest, un-pushy read we’re glad to give you, among the clinics we know well. Just ask.

Frequently asked
How long does a thread lift last?
It depends on the thread. PDO threads: the material dissolves in about 6–8 months, with visible lift often lasting around a year. PLLA threads: results commonly last around two years. PCL threads: often two to three years. These are ranges — how long yours lasts depends on your skin, the number and placement of threads, and the technique, so your clinic's assessment matters more than any single number.
How does a thread lift work if the thread dissolves?
Two effects. First, the barbed threads mechanically lift and reposition soft tissue, giving an immediate result. Second, as the thread slowly dissolves, it triggers a controlled response that stimulates new collagen — so the skin firms gradually, and part of the benefit remains after the thread itself is gone. The collagen effect is why the result outlasts the material.
What's the downtime after a thread lift?
Low. Mild swelling, bruising, or a tight feeling is common for the first several days, and most people return to normal social life within two to three days. Clinics generally advise avoiding strenuous exercise, exaggerated facial movements, and sleeping on your side for around two weeks. Your clinic will give aftercare specific to you.
Is a thread lift the same as a facelift?
No. A thread lift is a non-surgical refinement — it lifts and firms modestly and its effect is temporary. A surgical facelift is a larger, longer-lasting operation with real downtime. Threads suit people who want a subtle lift with little recovery, not those seeking the scale of surgery. Matching your expectation to the treatment is the most important step.
