Quick answer: A thread lift uses dissolvable threads placed under the skin to lift sagging tissue and stimulate collagen. PDO threads dissolve in about 6 months, while PCL threads last longer, often 12 to 18 months. Expect swelling, tightness and possible bruising for about a week, so thread lifts suit longer stays better than quick trips.
How thread lifting works
Threads are inserted with a fine needle or cannula. Barbed or cog threads grip tissue and pull it upward for an immediate lift, while smooth mono threads mainly stimulate collagen and improve texture. As threads dissolve, new collagen helps maintain firmness.
PDO vs PCL threads
- PDO (polydioxanone): most common, dissolves in around 6 months, results often last 6 to 12 months.
- PCL (polycaprolactone): dissolves more slowly, stimulates collagen longer, results commonly 12 to 18 months.
- PLA/PLLA threads: also longer-lasting with strong collagen stimulation.
Cog vs mono threads
- Cog threads: for lifting jowls, cheeks and the jawline.
- Mono threads: for fine lines, skin tightening and texture.
Who is a good candidate?
People with mild to moderate sagging and reasonable skin thickness, usually in their 30s to 50s. Severe laxity responds better to surgery.
Recovery timeline
- Days 1 to 3: swelling, tightness, possible dimpling.
- Days 4 to 7: most swelling and bruising settles.
- 2 to 4 weeks: tightness fades and results look natural.
Risks
- Dimpling or puckering, usually temporary.
- Asymmetry or visible thread ends.
- Infection, which needs prompt treatment.
- Rarely, thread migration or nerve irritation.
Aftercare
- Avoid wide mouth opening, facial massage and dental work for 2 weeks.
- Sleep on your back for a few nights.
- Skip saunas and intense exercise for a week.
How many threads are used?
The number of threads depends on the type and the area. A lower-face lift with barbed (cog) threads may use several threads per side, while mono threads for skin texture can involve many fine threads placed in a mesh pattern. Your doctor should explain how many of each type will be used and why, because this affects both the result and the price.
Thread lift prices in Busan
Thread lifts in Busan typically cost about ₩300,000 to ₩2,000,000 per session in 2026, depending on the thread material, brand and number of threads. PCL and PLA threads usually cost more than PDO because they last longer.
Common treatment areas
- Jowls and jawline for a sharper lower face.
- Mid-cheeks to soften nasolabial folds.
- Brows for a subtle lift.
- Neck for mild laxity.
- Nose bridge, using specialised threads.
Thread lifts vs HIFU and fillers
HIFU builds collagen gradually without repositioning tissue, while fillers restore volume. Threads physically lift tissue for an immediate visible change. Many clinics combine HIFU or RF with threads and a small amount of filler for a balanced, longer-lasting result.
When to contact the clinic
Mild pain, tightness and dimpling are normal. Contact the clinic promptly if you notice increasing pain, redness, warmth, discharge, a thread end poking through the skin, or marked asymmetry after swelling settles.
Planning a thread lift during a trip to Busan
Plan for about a week of visible swelling, tightness and possible bruising, and avoid wide mouth opening and facial massage for two weeks. Most people need one session; a follow-up visit a few days later is common. Most international visitors stay in Seomyeon, the city's largest clinic district and a central subway hub, or in Haeundae and Centum City near the beach. Seomyeon is about 35 minutes from Gimhae International Airport by light rail and subway and about 12 minutes from Busan Station (KTX) on Line 1, while Haeundae is about 30 to 40 minutes further east on Line 2. Book your consultation before you arrive, share your travel dates with the clinic, and leave at least one buffer day before your flight in case you want a follow-up check.
Questions to ask at your consultation
- Which thread type and how many threads will you use?
- How long should I expect the result to last?
- What should I avoid while the threads settle?
- Is the clinic registered with HIRA, and who will perform the treatment?
- Does the written quote include VAT, numbing cream and any follow-up visit?
- How can I contact the clinic with questions after I return home?
How to choose a clinic for thread lifting in Busan
Busan has roughly 1,000 registered clinics across dermatology, plastic surgery and other specialties, so it is worth comparing a few before you book. Start by checking that the clinic is listed with Korea's Health Insurance Review and Assessment Service (HIRA), then look at the doctor's specialty and experience with thread lifting. In Korea, a clinic name that includes "Dermatology" (피부과) or "Plastic Surgery" (성형외과) indicates the director is a board-certified specialist in that field. During consultation, a good clinic will explain realistic results, side effects and alternatives, give you a written quote, and never pressure you into same-day packages. Read recent patient reviews with a critical eye, and favour clinics that provide English aftercare instructions and a clear way to contact them after you leave Korea.
