What changes with MINT lift? The range where thread works and where surgical facelift cannot reach

MINT lift is a procedure where barbed threads made of PDO (polydioxanone), which dissolves over time, are inserted under the skin to lift and secure sagging tissue[1][2]. Since the threads are absorbed in 6–8 months, you cannot expect the large movement or long-lasting results of a surgical facelift[3][4]. It is suited to mild to moderate sagging, and the main effect centers on adding firmness while maintaining position[3].

What are the threads made of, and how do they work?

The same material as surgical sutures. MINT lift uses purple absorbable PDO monofilament threads; the thread length is reported as 43 cm, and the diameter specification is USP 0.[1]PDO has a safety record as a suture material, is absorbed in 6–8 months, and stimulates collagen production.[3].

The role differs by presence or absence of barbs. Threads without barbs primarily increase collagen to improve skin quality, but have limited lifting power.[3]Threads with barbs catch on tissue and remain in place, allowing positional change.[3]Unlike injections or device treatments, the ability to physically lift tissue is the characteristic feature of Thread lift.[5].

How long does the effect last?

Research has confirmed results up to around 6 months. A prospective study using three-dimensional barbed PDO threads in the midface and nasolabial folds evaluated patients at 1 month, 3 months, and 6 months, reporting consistent wrinkle improvement through 6 months.[3]A report summarizing the treatment procedure for MINT lift also states that clinically the duration is approximately 8 months at most, and long-term follow-up research is needed.[6].

Caution is warranted regarding differences between advertising and research. The prospective study authors note that while advertising claims 12–18 months, another report found that sagging returned in 50% by 6 months and in 14% by 8 weeks, and that lifting effect alone fades by 6 months.[3]The clinical guidelines of the Japanese Society for Aesthetic Surgery also limit Thread lift to a weak recommendation, stating that while temporary improvement can be expected, the effect is not large and duration is short.[4].

Who is it suited for? Is a higher number of threads always better?

It is suited to mild to moderate facial sagging.[3]Thicker threads with larger barbs are suited to heavy lower-face sagging, while thinner threads with smaller barbs are suited to delicate areas like around the eyes.[5].

Increasing the number of threads does not necessarily increase satisfaction. A study of 1,500 people who underwent PDO thread lift at Japanese aesthetic surgery clinics found that 3.4% returned dissatisfied with results.[7]Higher age and greater numbers of threads more often lead to dissatisfaction; the reported threshold is age 43 and 10 threads.[7]It is more important to first determine whether the degree of sagging is within the range that threads can address, before adding more threads.

Compared to surgical facelift, what cannot be done?

Large tissue movement and fixation cannot be achieved. Textbooks define Thread lift as a less invasive method to lift facial and neck soft tissue with barbed threads.[2]Because it is less invasive, the amount of movement possible and duration are limited.[4][2].

In exchange, the burden is lighter. An expert panel on absorbable thread lift cites shorter operative time and recovery period, no need for general anesthesia, and inconspicuous scarring because skin is not cut, as advantages compared to surgical facelift.[8]A report summarizing the MINT lift procedure also states that correction for over-insertion is unnecessary.[6]Whether you want a light refinement or substantial movement determines the answer between thread and surgical approaches.

What complications can occur?

Likelihood varies by thread shape. A review of Thread lift overall reports that U-shaped threads fixed at the temples achieve visible lifting in 85–90%, but show bleeding in 15–20%, skin depressions in 12–18%, and tissue damage at thread exit sites in 5–10%.[5]I-shaped threads have fewer complications, under 5%, but produce modest lifting.[5].

These are general figures for thread shape overall, not complication rates specific to MINT lift.[5]It is worthwhile to ask beforehand what shape thread will be used on you, how many, and how depressions or bleeding will be managed if they occur.

Four things to confirm at consultation

First, whether your sagging falls within the mild to moderate range.[3]Second, the shape and number of threads to be used, and the reason for that number.[5][7]Third, how to maintain results after 6 months and how future treatment is planned.[3][6]Fourth, the difference compared to choosing a surgical facelift.[2][8].

The cause of sagging differs by person: skin laxity, fat descent, or bone loss. Based on the article alone, you cannot decide whether threads are sufficient. At consultation, have your sagging assessed in terms of layer and degree, and ask for explanation of the changes threads can achieve and their duration, alongside the surgical options.
