QTL and QTLs Thread Lift: How This Technique Differs

Medically reviewed by Dr. SuHyun Kim, Medical Director, Aube Clinic

If you have been researching non-surgical facial lifting in Korea, you may have come across the names QTL and QTLs among the many thread systems now offered in Seoul clinics. These are two of the thread options used at Aube Clinic in Yongsan-gu, and prospective patients understandably want to know what actually sets them apart from the more familiar thread names. The honest answer is that the differences between thread systems are usually a matter of thread structure, insertion approach, and how a physician plans the treatment, rather than one system being universally superior to another. This guide explains how the QTL and QTLs technique works, how it compares to thread lifting in general, why it is not the same thing as a surgical facelift, and what a realistic outcome looks like.

What Are QTL and QTLs Threads?

QTL and QTLs are absorbable thread systems used in non-surgical thread lifting. Like other threads in this category, they are fine, dissolvable sutures inserted beneath the skin to reposition mildly sagging soft tissue and to encourage the skin's own collagen response along the path of the thread. As a category, absorbable thread lifting relies on the same broad principle: the thread provides a temporary mechanical scaffold, and over the following months the material is gradually broken down and absorbed by the body while a mild tissue-repair response develops around it.

It is worth being precise here. QTL and QTLs are marketed primarily within the Korean aesthetic market, and there is no established United States regulatory documentation specific to these named systems. For that reason, this article describes them at the level of the underlying technique rather than making device-specific claims. When a clinic or website makes a strong assertion about a proprietary thread doing something no other thread can, that claim should be read with healthy skepticism, because the published evidence base for thread lifting is broadly about the method itself rather than about any single brand outperforming all others.

How Thread Lifting Works: The Basic Mechanism

To understand what QTL and QTLs offer, it helps to understand thread lifting in general. In a thread lift, a physician uses a fine needle or cannula to place absorbable threads into a specific plane beneath the skin. Many lifting threads carry small barbs, cones, or textured segments that gently grip the underlying tissue, which allows the physician to reposition lax skin slightly upward and hold it in a more favorable position. According to the American Society of Plastic Surgeons, a thread lift uses temporary sutures to produce a subtle but visible lift, suspending the skin rather than surgically removing it.

There are two effects at work. The first is immediate and mechanical: the threads physically reposition tissue, which can create a modest lift you may notice soon after the procedure. The second is gradual and biological: as absorbable threads such as polydioxanone (PDO) dissolve through hydrolysis over roughly four to six months, they stimulate a localized collagen response that can contribute to firmness and skin quality. Peer-reviewed work on polydioxanone threads describes them as a non-surgical option that provides subtle lifting of sagging tissue while promoting collagen synthesis. This dual action, mechanical plus biological, is common to well-designed absorbable thread systems, including the general category into which QTL and QTLs fall.

What Makes the QTL and QTLs Technique Different

When comparing thread systems, the meaningful differences usually come down to a few practical variables rather than a single headline feature. These include the thread's structure and gripping design, the flexibility and tensile behavior of the material, the insertion pattern the physician uses, and how the system is matched to a particular area of the face. A thread designed with a certain barb or anchoring pattern may lend itself to a particular vector of lift or a particular tissue depth, which is why experienced physicians often keep several thread systems available rather than using one product for every patient and every concern.

At Aube Clinic, thread selection is treated as the result of an individualized assessment rather than a fixed default. The clinic's positioning centers on personalized non-surgical facial lifting, with one patient per time slot and a consultation conducted directly by Dr. SuHyun Kim. Dr. Kim's background is focused specifically on facial lifting and non-surgical aesthetic procedures, and the clinic reports a cumulative volume exceeding 20,000 lifting cases across its full range of thread systems. In that context, the value of having QTL and QTLs available is less about the name on the box and more about widening the range of options a physician can draw on when tailoring a plan to your anatomy, your degree of laxity, and your goals. Dr. Kim also holds designations such as President of the International Thread Lifting Research Association; these are professional and society designations rather than specialty board certifications, and they should be understood in that light.

QTL and QTLs Are Not a Facelift

This is one of the most important points for anyone considering the treatment, and it is easy to lose sight of when marketing language uses the word "lift." A surgical facelift is a distinct operation in which a surgeon makes incisions, repositions deeper structural layers, and removes excess skin, typically producing a more dramatic and longer-lasting change. Thread lifting does none of that. It repositions tissue by a few millimeters and stimulates collagen, and it is best understood as a minimally invasive option for people with mild to moderate laxity rather than as a replacement for surgery.

The American Society of Plastic Surgeons is direct about this distinction, noting that thread lifts generally lift the face only slightly and create a more subtle, natural-looking result than a facelift, which makes them best suited to patients with mild to moderate signs of skin laxity. If your sagging is advanced, no thread system, including QTL or QTLs, will reproduce a surgical outcome. A responsible consultation should tell you honestly when your goals point toward surgery rather than toward threads, and Aube Clinic's single-doctor, no-pressure consultation model is intended to support exactly that kind of candid conversation. You can read more about the clinic's approach and philosophy on the Aube Clinic about-us page.

Regulatory Status: What US Patients Should Know

For patients based in the United States, regulatory context matters. QTL and QTLs are used within the Korean market, and there is no verified United States Food and Drug Administration clearance specific to these named thread systems. In plain terms, QTL and QTLs should not be described as US-FDA-cleared, and any page that does so is overstating what is documented. Thread lifting procedures performed at Aube Clinic are carried out in Seoul under the applicable Korean regulatory framework, not under US authorization.

This does not mean the technique is unstudied. The broad method of absorbable thread lifting has a substantial and growing body of peer-reviewed literature covering its mechanism, its outcomes, and its complications. What it does mean is that you should evaluate the physician's experience and the honesty of the consultation, rather than relying on a regulatory label that does not apply to these specific products in the US. If a clearer regulatory statement is important to your decision, ask the clinic directly and expect a straight answer.

Who Might Be a Candidate

Thread lifting in general, including QTL and QTLs, tends to suit adults with mild to moderate sagging along the cheeks, jawline, or lower face who want a non-surgical option with limited downtime and are comfortable with a subtle, gradual result. It is generally less suitable for people with significant skin laxity, very thin or fragile skin, active skin infection in the treatment area, or certain medical conditions that affect healing. Pregnancy and some medications may also make treatment inappropriate. Because candidacy depends on your individual anatomy and health history, it can only be confirmed in a consultation, not from an online description.

What to Expect: Results, Downtime, and Longevity

Realistic expectations are essential. Any lift produced by threads is modest, and results vary considerably from person to person depending on skin quality, the degree of laxity, the area treated, and how your body responds. Absorbable threads are temporary by design; because the material dissolves over months, the mechanical effect is not permanent, though the collagen-stimulating component may contribute to skin quality for a time after the threads themselves are gone. Nobody can guarantee a specific outcome or a specific duration.

Common, usually temporary effects after thread lifting include swelling, bruising, tenderness, and mild tightness or dimpling that typically settles as the area heals. Less common issues, described in the clinical literature, include visible dimpling, thread extrusion, asymmetry, or infection, which is one reason the procedure should be performed by an experienced physician who can plan carefully and manage any problem that arises. Aube Clinic performs procedures on a fully reserved, one-patient-per-slot basis with Dr. Kim personally performing treatment, and it offers follow-up care for issues such as asymmetry or thread-related side effects. If you are weighing your options or want to ask about candidacy, you can reach the clinic through the Aube Clinic contact page.

How Aube Clinic Approaches Thread Selection

Rather than promoting a single thread as the answer for everyone, Aube Clinic frames QTL and QTLs as two entries within a broader menu of thread systems that a physician can select from based on the specific face in front of them. The consultation is designed to assess facial proportions, the pattern and degree of sagging, and skin characteristics before any recommendation is made, and to set expectations honestly about what a non-surgical approach can and cannot achieve. That individualized, physician-led method, rather than any one product name, is the differentiator the clinic emphasizes.

The Bottom Line

• QTL and QTLs are absorbable thread systems used for non-surgical facial lifting; they work by mechanically repositioning tissue and stimulating a collagen response as the threads dissolve.
• Differences between thread systems mainly reflect thread structure, insertion approach, and physician planning, not one product being universally superior.
• QTL and QTLs are Korean-market systems with no verified US-FDA clearance, so they should not be described as FDA-cleared; treatment is performed in Seoul under Korean regulation.
• Thread lifting is not a facelift; it produces a subtle, temporary lift best suited to mild to moderate laxity, and results vary between individuals.
• At Aube Clinic, thread selection follows an individualized consultation with Dr. SuHyun Kim, who personally performs each procedure on a one-patient-per-slot basis.

Frequently Asked Questions

Are QTL and QTLs threads FDA-cleared in the United States?

No. QTL and QTLs are used within the Korean aesthetic market, and there is no verified United States FDA clearance specific to these named thread systems. Procedures at Aube Clinic are performed in Seoul under the applicable Korean regulatory framework. If regulatory status is important to your decision, ask the clinic directly.

How is a QTL or QTLs thread lift different from a facelift?

A facelift is surgery that involves incisions, repositioning of deeper structures, and removal of excess skin, producing a more dramatic and longer-lasting result. Thread lifting is minimally invasive and repositions tissue by only a few millimeters while stimulating collagen. It suits mild to moderate laxity and is not a substitute for surgery.

How long do the results last?

Absorbable threads are temporary because the material dissolves over several months, so the mechanical lift is not permanent. The collagen-stimulating effect may support skin quality for a time afterward, but longevity varies widely by individual, area treated, and skin condition. No specific duration can be guaranteed.

Is the procedure painful, and is there downtime?

Thread lifting is typically performed using local numbing, and many patients describe manageable discomfort during the procedure. Temporary swelling, bruising, and tenderness are common afterward and usually settle over days. Your individual experience and recovery guidance are best reviewed during your consultation.

Who is not a good candidate for thread lifting?

People with significant skin laxity, very thin or fragile skin, active infection in the treatment area, certain healing-related medical conditions, or pregnancy may not be suitable candidates. Candidacy depends on your individual anatomy and health history, which can only be assessed in person by the treating physician.

What are the possible side effects?

Common temporary effects include swelling, bruising, tenderness, and mild tightness. Less common issues reported in the medical literature include dimpling, thread extrusion, asymmetry, or infection. Choosing an experienced physician who can plan carefully and manage complications reduces these risks.
