Mint Thread Lift: From the Principles of Lifting a Sagging Face to Side Effects

Mint Thread Lift is a non-incisional lifting procedure that physically pulls up sagging tissue by engraving microscopic protrusions called cogs onto PDO (polydioxanone) absorbable threads. The core mechanism is a dual structure: the cogs on the thread's surface hook onto the sagging skin and fat to pull them upward, and as the thread dissolves over time, collagen grows in its place.

Here, MINT is not just a generic term for "thread," but a specific brand name used as an acronym for 'Minimally Invasive Nonsurgical Thread,' and it is a product approved by the US FDA 510(k) and the South Korean Ministry of Food and Drug Safety. Understanding that the immediate pulling effect and the gradually building elasticity are two separate phenomena will reduce any disappointment after the procedure.

🧵 How Does Mint Thread Lift Work?

The principle is divided into two pathways. First is physical traction. The bidirectional cogs engraved on the thread hook onto the tissue, immediately moving it upward. This is why you feel the change right away in front of the mirror as soon as the procedure is finished.

Second is collagen and elastin induction. PDO is a material that has been used as a surgical suture for decades, dissolving in the body through hydrolysis over about 6 to 12 months. As the thread decomposes, the surrounding tissue reacts to produce new collagen, and this effect gradually appears between 1 to 3 months after the procedure. It has a different timeline from the immediate lifting effect.

One structural feature of the MINT thread is that the cogs are molded (press-molded) rather than made by cutting the thread's surface with a knife, explaining that this reduces the loss of tensile strength. In a procedure where pulling force is necessary, it would be problematic if the thread itself snapped or lost its strength.

📌 Key Summary: Mint Thread Lift = Immediate traction of cogs + Collagen generation during PDO decomposition. These two effects work with a time lag.

⏳ When Do the Effects Appear and How Long Do They Last?

The immediate pulling effect is felt right after the procedure, while the improvement of elasticity by collagen takes place over a period of 1 to 3 months. It is good to know in advance that the timing of these two effects is different.

The duration varies greatly by individual, but it is usually expected to last 6 to 18 months. Since the collagen created in place of the completely dissolved PDO thread supports elasticity for a while, the effect does not vanish immediately when the thread disappears.

There are many misunderstandings regarding the number of threads, but more threads do not necessarily mean better results. The count is adjusted within about 4 to 10 threads per side depending on the degree of sagging and the area, and what determines the outcome is the design of the insertion direction, layer, and fixation point, rather than the quantity.

📌 Key Summary: Immediate pulling happens right away, the collagen effect takes 1 to 3 months, and the duration is roughly 6 to 18 months. Design, not the number of threads, creates the results.

🔬 What Is the Difference Between Thread Materials? (PDO, PLLA, PCL)

Absorbable threads have different dissolving speeds and characteristics depending on the material. While Mint thread is typically represented by the PDO class, knowing the material spectrum makes consultation easier.

Just because a material lasts longer does not make it unconditionally superior. The suitable material differs depending on the facial area, skin thickness, and desired duration. When consulting for thread lifts at Onlif Clinic, this part is also tailored to the individual's skin condition.

🆚 How Is It Different from Ulthera, Thermage, and Facelift Surgery?

The lifting category is broad. Since each targets different layers and uses different methods, they serve different purposes rather than one replacing another.

Since ultrasound HIFU and radiofrequency RF like Ulthera and Thermage work on firming elasticity through thermal energy, they can complement each other at different layers when combined with the physical traction of threads. Onlif Clinic also takes an approach of combining thread lifting with HIFU and RF tailored to individual skin conditions.

A facelift is an incisional surgery that directly dissects and fixes the SMAS, showing clear effects for severe sagging, but it requires a long recovery and is invasive. Onlif is a clinic from a dermatological perspective that does not handle incisional surgeries involving knives, and we recommend approaching sagging and loss of elasticity with non-surgical treatments first. However, we honestly state that there are limits to using only threads if the sagging is too severe for the threads to withstand the weight of the tissue.

📌 Key Summary: Threads provide immediate traction, while HIFU and RF firm elasticity with heat. They are combined or chosen differently based on the degree of sagging.

⚠️ What Are the Side Effects and Points to Watch Out For?

Even if it is non-surgical, it is clearly an invasive procedure. We divide them from common reactions to rare but important ones.

• Swelling: A few days to 2 weeks / Bruising: 1 to 2 weeks / Foreign body sensation or tightness: Around 1 to 4 weeks

• Dimpling (Skin indentation): A phenomenon where the surface slightly sinks at the thread insertion site. It is among the most common and usually subsides over time.

• Asymmetry, foreign body sensation, thread exposure: These can be related to the design or insertion depth, making the operator's skill level crucial.

• Infection and granuloma: These are rare but serious side effects that require early action if they occur.

Emergency signals to particularly watch out for: If the skin color becomes pale or turns purple, it suggests potential blood vessel compression or damage, so you must contact the medical staff immediately. These symptoms should not be ignored.

There is also a pre-procedure checklist. Anticoagulant ingredients such as aspirin, warfarin, omega-3, vitamin E, and ginkgo biloba extract increase the risk of bleeding and bruising, so you must inform us in advance. If you have a keloid constitution, autoimmune disease, are taking immunosuppressants, have uncontrolled diabetes, or are pregnant/breastfeeding, the suitability of the procedure must be carefully evaluated.

📌 Key Summary: Swelling, bruising, and dimpling are common recovery reactions, while paleness or purple discoloration requires immediate contact. Prior notification of anticoagulant intake is mandatory.

🕐 What Is the Procedure and Recovery Like?

The procedure is performed under local anesthesia and takes about 30 to 60 minutes. Since the flow involves inserting threads through entry points after anesthesia, mapping the direction, pulling, and fixing them, the burden is significantly lighter compared to incisional surgery. In many cases, returning to daily life is possible on the same day or the following day.

However, care is required for about 4 weeks after the procedure. Avoid strong facial massages, saunas, intense exercise, drinking alcohol, sleeping on your stomach, or opening your mouth wide. If you overstrain before the threads settle, they might migrate or lose their holding power.

A practical tip: If you have plans for dental treatments where you need to open your mouth wide for a long time, it is better to arrange them before or well after the procedure. Conversely, you do not have to worry about MRI scans. PDO is a polymer absorbable material, not metal, so it generally does not affect MRIs.

📌 Key Summary: Local anesthesia for 30–60 minutes, return to daily routine on the same or next day. The key is to protect the time for the threads to settle for 4 weeks.

🎯 Who Is a Good Candidate, and When Should You Reconsider?

Mint Thread Lift is suitable for early to moderate sagging, or when the nasolabial folds, cheeks, and jawline start to collapse. It fits those who want natural improvement rather than major, drastic changes.

On the other hand, if sagging is severe and the weight of the tissue is substantial, the thread will have difficulty supporting that weight, rendering the effect limited. If the skin is too thin and lacks fat, the risk of the thread showing through must also be considered. Such conditions should be pre-screened during the diagnosis before the procedure.

Onlif Clinic operates on the premise that a single doctor cannot do everything perfectly, implementing a doctor-specialty system where doctors are in charge of procedures they perform best in their respective fields. Since thread lifting is a procedure where anatomical understanding and insertion design sense heavily dictate the results, we view this area with utmost care. It is not about changing the shape of the eyes, nose, or mouth, but reviving the natural impression that aging and sagging have hidden. That is the attitude Onlif holds toward lifting.

📌 Key Summary: Suitable for early to moderate sagging; separate judgment is needed for severe sagging or very thin skin. Design sense creates the results.

❓ Frequently Asked Questions (FAQ)

What is the difference between Mint Thread Lift and general thread lifts?

MINT is a specific brand name characterized by a structure that reduces the loss of tensile strength by molding bidirectional cogs. It is also distinguished from ordinary threads as a product approved by the FDA 510(k) and the Ministry of Food and Drug Safety.

How long does the effect last?

While there are individual differences, it typically lasts 6 to 18 months. Even after the PDO thread dissolves over 6 to 12 months, the formed collagen supports elasticity for a certain period.

When do the effects start to show after the procedure?

The immediate lifting from the pulling is felt right after the procedure, while the improvement in elasticity due to collagen generation appears gradually between 1 to 3 months after the procedure.

How long do swelling and bruising last?

Swelling can last from a few days to 2 weeks, bruising for 1 to 2 weeks, and tightness or a foreign body sensation for around 1 to 4 weeks. Most of these subside over time.

What should I do if dimpling (skin indentation) occurs?

This is a common occurrence at the thread insertion site and usually resolves over time. If it persists or is severe, it is advisable to consult with the treating medical staff to get it corrected.

Is it effective for severe sagging?

If the sagging is severe, the threads may not bear the weight of the tissue, resulting in limited effects. In this case, suitability must be carefully judged during pre-procedure diagnosis, and unreasonably increasing only the number of threads is not recommended.

Is it more effective when combined with Ulthera and Thermage?

Since threads provide physical traction and HIFU/RF firms up elasticity with thermal energy, they can complement each other at different layers. However, it is safe to consult with a specialist to determine the interval and order of combination based on your skin condition.

Can I get the procedure if I have an upcoming MRI scan?

PDO is a polymer absorbable material, not metal, and generally does not affect MRI scans. However, it is recommended to inform the scanning institution of your procedure history.

Is it okay to get the procedure while taking anticoagulants or aspirin?

Aspirin, warfarin, omega-3, vitamin E, and ginkgo biloba extract increase the risk of bleeding and bruising. Rather than stopping them arbitrarily, you must inform the medical staff of your medication history before the procedure to coordinate.

What should I do if I can feel the thread or if it shows outside the skin after the procedure?

There may be some foreign body sensation initially, but this usually subsides. If a thread becomes exposed outside the skin, or if discoloration or pain occurs, you should not ignore it and must contact the treating clinic immediately to have it checked.
