Quick answer: A thread lift usually lasts about one to two years, while skin tightening devices such as Ultherapy and Thermage usually last about a year per session. Threads give a stronger, immediate lift; devices build collagen gradually with less downtime. How long results last depends on your age, skin, sagging level and how you maintain them.
Key takeaways
- Threads often last one to two years; devices often about a year.
- Threads lift tissue physically; devices tighten with heat energy.
- Device results build over two to six months.
- Threads have more downtime than most devices.
- Combining both and regular maintenance can extend results.
What is a thread lift?
A thread lift uses dissolvable PDO or PLLA threads placed under the skin after numbing. Barbs or cones grip sagging tissue and lift it into a higher position, so you see a change right away. As the threads dissolve over months, collagen forms around them, which helps keep the result. Popular options in Korea include MINT Lift and Silhouette Soft.
What are skin tightening devices?
Skin tightening devices use energy to heat layers under the skin and trigger new collagen. Ultherapy uses micro-focused ultrasound to reach the deep SMAS layer. Thermage FLX uses monopolar radiofrequency to heat the dermis. Other options include HIFU devices such as Shurink and RF devices such as Oligio. Results build gradually over two to six months.
Which lasts longer?
- Thread lift: often about one to two years, depending on the thread type and number.
- Ultherapy: usually about a year from one session.
- Thermage FLX: usually about a year, sometimes longer.
- Other HIFU or RF devices: often about three to twelve months.
- Downtime: threads one to two weeks; devices usually a few days of mild redness or tenderness at most.
What affects how long results last?
Longevity is different for every person. Younger skin with more collagen holds results longer. Heavy sagging, big weight changes, smoking, strong sun exposure and poor sleep can shorten them. The number of threads, the thread material and the energy and shots used with devices also matter. Good skin care and sun protection help results last.
Which gives a stronger result?
Threads usually give a stronger, more visible lift because they physically move tissue. Devices give a more subtle change, but they improve skin firmness and texture across a wider area. Many people find devices enough for mild sagging and threads more useful for clear jowls.
Can you combine threads and devices?
Yes, and this often gives the longest-lasting result. Threads provide the immediate lift, while Ultherapy or Thermage tighten the deep layer and skin and keep building collagen. Many doctors space treatments a few weeks apart, but some can be done on the same trip.
How should you plan maintenance?
A common plan is a yearly device session, such as Ultherapy or Thermage, with threads every one to two years if needed. Lighter HIFU or RF sessions in between can help. Your doctor will suggest a schedule based on how your skin responds.
Is it safe?
Both are safe in experienced hands. Thread risks include bruising, swelling, asymmetry and visible threads. Device risks are rare and include small burns, blisters or temporary numbness. Choose genuine products and a doctor who uses them often.
How to decide
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Visitors often ask which lifting option lasts longest. The answer depends on your sagging level, recovery time and how often you can return for maintenance.
Frequently asked questions
Do threads last longer than Ultherapy?
Often yes, about one to two years versus about one year, but it varies.
Which has less downtime?
Devices usually have less downtime than threads.
Can I repeat both?
Yes. Many people repeat devices yearly and threads every one to two years.
Will results disappear suddenly?
No. Results fade gradually as the skin continues to age.
