Quick answer: A thread lift places dissolvable threads under the skin to lift and support sagging tissue, with results visible immediately and improving as collagen forms around the threads. In Korea the main materials are PDO, PLLA and PCL, and the thread design (smooth, screw or barbed) decides whether it tightens, adds support or lifts. Results typically last six to eighteen months. Swelling settles within about a week.
How a thread lift works
A doctor inserts fine threads through a few small entry points using a needle or cannula. Barbed or cogged threads grip the tissue and pull it into a lifted position. Over the following months the body forms collagen around the threads, which helps the effect last after the threads dissolve.
Thread materials
- PDO (polydioxanone): the most common, dissolves in about six months; results often last six to twelve months
- PLLA (poly-L-lactic acid): dissolves more slowly and stimulates collagen strongly
- PCL (polycaprolactone): the longest-lasting material, often quoted at one to two years
Thread designs
- Mono or smooth threads: many fine threads for skin tightening and texture, little lift
- Screw threads: twisted threads that add support and a little volume
- Barbed or cog threads: threads with small hooks for real lifting of cheeks, jowls and the jawline
- Cone threads: threads with small cones that hold tissue, used for lifting and contour
Who is a good candidate?
- Mild to moderate sagging of the cheeks, jowls or jawline
- People in their 30s to 50s who want more lift than energy devices give, without surgery
- Those who accept a temporary result and occasional repeat treatment
Thread lifts are less suitable for heavy, loose skin, which needs a surgical facelift, or for very thin faces, where threads may be visible.
The procedure
- Consultation and marking of lift vectors
- Local anaesthetic at entry points, sometimes sedation
- Insertion of threads, usually 30 to 60 minutes
- You go home the same day
Recovery
- Swelling, bruising and tightness for three to seven days
- Mild pain when opening the mouth wide or chewing for one to two weeks
- Avoid facial massage, dental work and wide yawning for two to four weeks
- Sleep on your back for the first week if possible
Visitors should allow at least five to seven days in Seoul before flying, and ideally a follow-up check.
Possible complications
- Dimpling or puckering at entry or anchor points, usually settling within weeks
- Asymmetry
- A thread end becoming visible or poking through, which may need removal
- Infection, which is uncommon but needs prompt treatment
- Rarely, nerve irritation or prolonged pain
Choose a doctor experienced with the specific thread type and ask how complications are handled after you return home.
Price
Thread lifts are priced by thread type and number of threads, or per area. Barbed and PCL threads cost more than mono threads. See our
price guide for current KRW ranges.
Frequently asked questions
How long does a thread lift last?
Six to eighteen months, depending on thread type, your skin and lifestyle.
Can I combine threads with Ultherapy or fillers?
Yes, but timing matters. Many doctors do energy treatments before threads, or wait several weeks after.
Is a thread lift better than a facelift?
It is less invasive with shorter recovery, but the lift is smaller and temporary. For significant sagging, surgery gives a stronger, longer result.
