Thread lift longevity varies this much depending on the type of thread

The maintenance period of thread lifting is usually around 6 months to 2 years. However, there are quite a few variables to lump into this one number. The actual experienced duration varies greatly depending on which thread is used, what the thread structure is like, and what the skin condition is. The biggest turning point is the type of thread. PDO lasts 6 to 12 months, PLLA lasts 12 to 24 months, and PCL can last from 18 months to as long as 4 years.

There is one thing that must be pointed out here: the period during which the thread dissolves and the period during which the lifting effect is maintained are separate. Just because the thread has been completely absorbed does not mean the effect disappears on that day. This is because the collagen produced while the thread stimulates the inside of the skin holds onto elasticity for a while even after the thread disappears.

🧵 What is thread lifting, and why does the maintenance period differ for each thread?

Thread lifting is a procedure in which specially processed medical threads are inserted into the skin to lift sagging tissue and stimulate collagen production through that stimulation. A major advantage is that there is no incision and recovery is fast.

The effect comes in two ways. One is the immediate traction effect of the thread physically pulling the tissue, and the other is the improvement of elasticity by collagen and elastin produced as fibroblasts are activated around the thread. Thanks to this second mechanism, the effect gradually decreases even after the thread dissolves, rather than cutting off abruptly.

The reason why the maintenance period is different for each thread is, after all, this: how long the thread can endure in the body and continue to stimulate collagen. Absorbable threads are hydrolytically decomposed into water and carbon dioxide, a material that has been thoroughly proven as a suture for a long time. However, the decomposition rate varies depending on the component, resulting in a difference in retention.

📌 Key Summary: The period during which the thread dissolves and the period during which the effect is maintained are separate, and collagen holds onto elasticity for a certain period even after the thread disappears.

📊 Comparison of retention by thread type: PDO, PLLA, and PCL

Absorbable threads used in thread lifting are largely divided into three components. This difference is the key to determining the maintenance period.

PDO is the most widely used component. It has less burden and is relatively acceptable, so those who are new to thread lifting encounter it often. Instead, the maintenance period is relatively short.

PLLA pushes collagen production more strongly than PDO. As such, the elasticity improvement effect remains for a long time. PCL has the slowest decomposition rate, so it has the longest maintenance period. It also has less foreign body sensation, so its preference has been rising recently.

However, make no mistake. PCL is not always the correct answer. The appropriate thread varies depending on the degree of sagging, skin thickness, desired naturalness, and budget.

📌 Key Summary: The maintenance period gets longer in the order of PDO < PLLA < PCL, but a thread that lasts unconditionally long is not necessarily good; a thread that fits your condition is a good thread.

🔩 Thread structure also dominates the maintenance period — Cog Threads vs. Mono Threads

Just as much as the component, the 'appearance' of the thread is also important. Even for the same PDO, if the structure is different, the job it does is different.

• Cog Thread: There are protrusions/barbs on the surface of the thread to physically catch and pull the tissue. Because it is a structure specialized for lifting, its traction is strong, and the lifting maintenance period is generally longer than that of mono threads.

• Cone Thread: A form with improved fixing and pulling power using cone-shaped structures. It is used together with cog threads in areas requiring pulling.

• Mono Thread: This is a smooth thread. Rather than pulling strongly, it is closer to improving skin texture and elasticity by inducing collagen. The lifting maintenance period is on the shorter side.

So, blindly increasing the number of threads does not proportionally lengthen the maintenance period. The results will improve only when the type of thread, structure, insertion depth, and design fit together comprehensively. This is a design issue of reading the facial structure and the direction of sagging, which is also a point where the practitioner's judgment plays a major role.

For reference, non-absorbable threads such as gold threads used in the past do not dissolve and remain in the body for a long time. Just because they remain does not mean the effect is semi-permanent, and their use is limited nowadays due to safety issues.

📌 Key Summary: Cog and cone threads are strong in pulling, while mono threads are closer to improving elasticity; the combination of type, structure, and design determines the maintenance period rather than the number of threads.

⏳ When does the post-procedure effect become the best?

Thread lifting is not at its peak immediately after insertion. Rather, it flows like this.

1. Immediately after procedure: The thread pulls the tissue, showing an immediate physical lifting. It may be slightly unnatural due to swelling.

2. 2–4 weeks later: The swelling subsides and the lines settle naturally.

3. Months 2–3: Experience the most stable and natural effect as collagen production is maximized.

In other words, it is correct to see that the real effect is completed two or three months later. It is better not to rush judgment just by looking at the appearance immediately after the procedure.

📌 Key Summary: The thread lifting effect is completed most stably in the 2nd to 3rd month when collagen fills up, not immediately after the procedure.

🌿 Management methods to extend the maintenance period and factors that reduce it

Even if the same thread is inserted, the experienced maintenance period varies depending on how you manage it.

Things to avoid for a month after the procedure

• Strong facial stimulation such as aesthetic deep-tissue massages

• Opening mouth wide, chewing hard food

• Sauna, steam room

• Sleeping face down

In particular, it is good to be careful during the first 1 to 2 weeks after the procedure as this is the period when the threads settle. If excessive stimulation is applied before the fixing power of the thread stabilizes, the maintenance period may be shortened.

Conversely, the representative factors that eat away at the maintenance period are also clear. Rapid weight change, smoking, and excessive UV exposure encourage collagen loss, accelerating the decline of the effect. Age, skin thickness, original elasticity, and degree of sagging also naturally have an effect.

Improving the skin's collagen environment itself by parallelizing procedures such as skin boosters can also help carry the thread lifting effect a little longer.

📌 Key Summary: Avoiding strong stimulation for a month after the procedure, combined with smoking cessation, UV protection, and weight management, is advantageous in preserving the maintenance period.

🔍 Comparison with HIFU, Thermage, Fillers, and Surgery

Thread lifting is not the only lifting procedure. We have summarized those that are frequently compared.

One thing to be careful about here. Heat energy procedures such as HIFU or Thermage can prematurely dissolve threads that have already been inserted. Therefore, when proceeding together, it is safe to do so before thread lifting or coordinate the order with sufficient time apart.

Fillers are of a different nature. Since it is a procedure to fill in lost volume rather than pull sagging, combination with thread lifting is considered when sagging and volume problems overlap, such as with nasolabial folds.

A facelift has the longest maintenance period but is an incision surgery. Considerations such as recovery burden and scarring follow. Onlif Clinic addresses aging and elasticity concerns with non-surgical procedures from a dermatological perspective, rather than cosmetic surgery involving a knife. Therefore, even for severe sagging, we first look at how far it can be improved with non-surgical methods such as All-Tight Lifting, thread lifting, and HIFU/RF. We recommend referring to surgery for informational purposes only.

📌 Key Summary: HIFU/Thermage heat procedures can quickly dissolve threads, requiring order coordination, and Onlif prioritizes improving sagging with non-surgical skin procedures.

⚠️ Reactions such as dimples and swelling, and the timing of re-treatment

After thread lifting, bruising, swelling, and dimple phenomena, where the skin appears slightly indented or uneven, may occur. Most of these alleviate over time, but if they persist for a long time or if asymmetry/thread protrusion is felt, it is good to get checked at the place where you received the procedure.

Re-treatment is usually talked about in 1 to 2-year cycles, but the correct answer is not fixed. Since it is a procedure where the effect gradually decreases, you can decide based on your condition when you feel your satisfaction has dropped.

📌 Key Summary: Dimples and swelling generally alleviate during the recovery process, and re-treatment is adjusted based on personal satisfaction, using 1 to 2 years as a standard.

💬 How Onlif views thread lifting

Onlif Clinic is a clinic in Gangnam focused on skin aesthetic procedures. We address aging and elasticity concerns with non-surgical procedures such as All-Tight Lifting, HIFU/RF, skin boosters, and fillers, as well as thread lifting.

What we aim for is not changing the shape of the face, but removing the sagging and loss of elasticity that obscure the inherent impression. Therefore, we do not recommend threads that last unconditionally long or unconditionally many threads. We consider it more important to read the facial structure and skin condition, and design the results without excessiveness.

We believe that one person cannot do all procedures well. Therefore, we operate in a way where each person takes charge of the procedure they do best by field. In the end, what governs the thread lifting maintenance period is not just the type of thread, but the design that fits my face and the management after that.

❓ Frequently Asked Questions

Does the effect disappear immediately when the thread is completely dissolved?

No. Collagen produced while the thread is being absorbed maintains elasticity for a certain period even after the thread disappears. The effect does not cut off abruptly one day but decreases gradually.

Does it maintain longer if more threads are inserted?

It is not proportional. Rather than the number of threads, the type, structure, insertion depth, and design of the threads work comprehensively. Inserting unreasonably many threads does not extend the maintenance period.

Should I choose PDO threads or PCL threads?

PDO has a maintenance period of 6 to 12 months, which has less burden and is popular, while PCL lasts the longest at 18 months to 4 years. However, since the appropriate thread varies depending on the degree of sagging, skin thickness, and desired naturalness, it is good to decide according to the condition.

When is the point when the thread lifting effect becomes the best?

It is not immediately after the procedure, but in the 2nd to 3rd month when collagen production is maximized. Immediately after the procedure, it may be somewhat unnatural due to swelling, and it becomes natural as the swelling subsides 2 to 4 weeks later.

Can I do Ulthera (HIFU) or Thermage together with thread lifting?

Combination is possible, but order coordination is necessary. Since heat energy-based procedures can prematurely dissolve inserted threads, we recommend doing them before thread lifting or proceeding with sufficient time apart.

When is it good to receive a thread lifting re-treatment?

Generally, a cycle of 1 to 2 years is used as a standard, but it is adjusted according to individual satisfaction and skin condition. You can check the condition and decide when you feel the effect has dropped.
