Quick answer: How long do PDO thread lift results last? PDO threads usually dissolve within about six months, but the collagen they stimulate helps the lift last longer. Many people see results for around 6 to 12 months, and sometimes longer. Age, skin quality, the number and type of threads, and lifestyle all affect how long a PDO thread lift lasts.
Key takeaways
- PDO threads typically dissolve within about six months.
- Collagen formed around the threads helps maintain the lift.
- Results often last around 6 to 12 months, sometimes longer.
- PLLA and PCL threads dissolve more slowly and may last longer.
- Combining threads with other treatments can extend results.
What is a PDO thread lift?
PDO stands for polydioxanone, a dissolvable material that has been used in surgical sutures for many years. In a PDO thread lift, thin threads are placed under the skin through small entry points. Barbed or coned PDO threads hold and lift sagging tissue, while smooth PDO threads, sometimes called mono threads, mainly stimulate collagen and improve skin firmness. Popular PDO thread brands in Korea include Mint Lift and others approved by the Ministry of Food and Drug Safety.
Why do results outlast the threads?
As PDO threads dissolve, the body forms new collagen and fibrous tissue along the thread paths. This acts as a natural support structure that helps keep tissue lifted after the threads are gone. The immediate mechanical lift comes from the barbs, while the longer-lasting effect comes from this collagen response.
What is the typical PDO thread lift timeline?
- Right after treatment: immediate lift, with swelling and tightness.
- Weeks 2 to 4: swelling settles and the lift looks natural.
- Months 1 to 3: collagen formation is active around the threads.
- Around month 6: PDO threads are mostly dissolved.
- Months 6 to 12 and beyond: collagen support continues, gradually softening over time.
How do PDO threads compare with PLLA and PCL threads?
- PDO: dissolves in about six months; results often last around 6 to 12 months.
- PLLA (for example, Silhouette Soft): dissolves more slowly and stimulates collagen strongly; results may last around 12 to 18 months.
- PCL: dissolves the slowest; results may last longer still.
Your doctor will choose the thread type based on your sagging, skin thickness and goals. Some plans combine different threads.
What affects how long results last?
- Age and skin quality: thicker, healthier skin often holds results longer.
- Degree of sagging: heavier sagging may relax sooner.
- Number and type of threads: more supportive plans may last longer.
- Facial movement: very expressive areas may relax faster.
- Lifestyle: sun exposure, smoking and big weight changes shorten results.
How can you make results last longer?
Protect your skin from the sun every day, avoid smoking and keep a stable weight. Follow aftercare carefully in the first weeks, avoiding facial massage and wide mouth opening, so threads anchor well. Many people combine thread lifts with Ultherapy or Thermage, skin boosters or Botox to maintain the overall result.
When should you repeat a PDO thread lift?
Many people repeat a PDO thread lift around once a year, depending on how their result fades. Some prefer to alternate thread lifts with energy-based lifting treatments. Your doctor will check how much support remains before planning more threads.
Is a PDO thread lift worth it?
A PDO thread lift offers a visible, immediate lift without surgery and with short recovery. For people with mild to moderate sagging who want quick results, it can be a good option. For heavier sagging, longer-lasting threads, combination plans or surgery may be more suitable.
Planning thread lifts as a visitor
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Thread lifts are a popular choice for visitors. Plan a few days in Seoul after treatment for swelling to settle before flying home.
