Hello, I'm Dr. Wangjin Lee, Director of Boost Clinic Cheongdam.
A common question: once the threads dissolve, does the lifting effect disappear along with them?
The short answer
Thread lifting works by using threads to hook and reposition sagging fat and tissue. The visible lifting effect varies by person, but it's generally understood to start gradually decreasing around the 6-month mark, as the threads begin to dissolve.
How the threads actually lift tissue
Threads come in PDO, PLLA, and PCL — all absorbable materials that dissolve gradually inside the body.
Thread types include cog threads, with tiny barbs along the surface, cone threads, with cone-shaped structures attached along the thread, and smooth mono threads and spiral threads, which have no barbs at all.
Cog and cone threads are placed just under the skin, in the shallow subcutaneous fat layer, hooking sagging tissue and fat like a grappling hook and repositioning it upward. Cone threads, in particular, have a somewhat higher reported likelihood of causing visible dimpling, so matching thread thickness and depth carefully matters.
Mono and spiral threads aren't primarily for lifting — their purpose is stimulating collagen production in thin skin. Once placed, firm tissue gradually forms around the thread over time, helping anchor the lifted position in place.
Does the lift disappear when the threads dissolve?
The lift you see immediately after treatment comes from the mechanical pulling force of the thread itself on the tissue. So as the thread dissolves, that force naturally decreases, and the visible effect gradually fades along with it.
In simpler terms: the thread acts as scaffolding for the cheek for the first several months, then is slowly absorbed while contributing to collagen formation in the surrounding tissue.
The visible lifting effect is generally understood to gradually decrease starting around the 6-month mark, as the threads begin dissolving.
That said, even after the thread has fully dissolved, the firm tissue that formed around it partially remains and continues to help hold the repositioned area in place.
Reported maintenance periods by material, which vary with individual skin thickness and fat volume, are as follows:
| Material | Reported duration | Characteristics |
|---|---|---|
| PDO | ~6–8 months | Absorbs relatively quickly; suited to an initial lift and a lower-commitment first treatment |
| PLLA | ~12–18 months | An earlier-generation collagen-booster material, used before PCL; specialized for gradual, self-generated collagen renewal |
| PCL | ~18–24 months | Breaks down most slowly of the three; high flexibility with long-term collagen stimulation and retention |
Given this, repeat treatment is generally planned no sooner than 6 months out, with a check-in at that point to assess how much effect remains.
Where it's used, and how the nasolabial area is approached
The primary treatment area is the deep cheek fat pad.
Threads are anchored near the cheekbone and designed to run toward the corner of the mouth. For the nasolabial fold area specifically, where volume has already decreased significantly, threads alone tend to have real limits — filler is generally considered alongside them.
Pulling the thread too aggressively can cause dimpling, an uneven contour, or asymmetry between the two sides — so controlling and distributing the tension carefully matters.
Who it suits, and aftercare
Thread lifting is generally understood to suit patients in their 30s–50s, at the early stages of visible aging, with reasonably thick skin and sufficient fat. If skin is very thin or fat volume is low, results may be underwhelming, or discomfort more likely.
After treatment, patients are generally advised to avoid exaggerated facial expressions for about 1–2 weeks, and to avoid saunas, intense exercise, or massage for about a month.
No treatment guarantees an identical result for everyone, and individual variation is expected.
Key takeaways
Thread lifting hooks and repositions subcutaneous fat using threads; the visible lift gradually decreases starting around the 6-month mark, as threads begin to dissolve. By material, reported durations are roughly PDO 6–8 months, PLLA 12–18 months, and PCL 18–24 months. The primary treatment area is the deep cheek, and the nasolabial fold is generally treated alongside filler.
FAQ
How long does thread lift actually last? By material, reported durations are roughly PDO 6–8 months, PLLA 12–18 months, and PCL 18–24 months. The visible lifting effect is generally understood to start decreasing around 6 months, as threads begin dissolving, and individual variation applies.
Does the lift disappear once the thread dissolves? The lift right after treatment comes from the thread's direct pulling force, so yes, it gradually decreases as the thread dissolves — but not all at once. It's generally described as fading gradually from around the 6-month mark, and the firm tissue that forms around the thread continues to help somewhat afterward.
What's the difference between cone and cog threads? Cog threads use tiny barbs on the surface; cone threads use cone-shaped structures along the thread — both hook sagging tissue and fat to lift it. Cone threads have a somewhat higher reported rate of dimpling, so thread thickness and placement depth matter.
Does thread lift treat the nasolabial fold too? If volume there has already decreased significantly, threads alone tend to have real limits, and filler is generally considered together with the thread lift. Over-tightening can cause dimpling or an uneven contour.
