"Does a thread lift really work on nasolabial folds?" Verifying that question with research data
Once you start to mind your nasolabial folds, you sigh every time you look in the mirror. Many people have likely had such an experience.thread lifteven when it comes up as a candidate, many people are left with the question "how much will it actually change?" and can't quite take the first step. We are often asked in consultations, "Will it really change?", and

"I'm afraid of cutting surgery, but I want to do something about my nasolabial folds," "hyaluronic acid alone has started to feel insufficient." To such people, we convey this based on the figures of clinical research, not on impressionistic anecdotes.
The actual data on the "nasolabial-fold lift effect" shown by research
In clinical research on the effect of thread lifts, there are reported cases of improvement in midface lifting. In procedures using 3D bidirectional barbed threads, cases have been confirmed in which improvement was seen in the depth of the nasolabial groove. However, it is also reported that results vary depending on measurement conditions, subject selection criteria, and an individual's skin type and bone structure.
Unlike conventional evaluation based on "patient satisfaction" alone, research that can confirm the effect with figures is valuable, but it is important to understand that not everyone gets the same effect.
A 3D bidirectional barbed thread is a thread with a special structure that has multidirectional protrusions (barbs) on its surface. Compared with conventional unidirectional barbs, it is said to havestronger anchoring power in the tissue, and in some cases a three-dimensional lift effect can be expected.
It is reported that in some cases, after the procedure the soft tissue of the midface moves upward and a tendency toward improvement in the depth of the nasolabial folds is seen. However, it is also reported that the effect varies between individuals and that results fluctuate with age, skin type, and the degree of sagging.
Why the type of thread and insertion angle matter for "nasolabial folds"
When it comes to improving nasolabial folds, some people may picture "putting threads directly into the nasolabial fold." But in reality,the approach of indirectly making the nasolabial folds shallower by lifting the midface area of the cheek, rather than the nasolabial fold itself,is the mainstream.
What determines the effect here is the type of thread and the insertion angle.
Differences by thread type
- Barbed thread (cog thread): the protrusions catch on the tissue and lift physically. A type for which there are reported cases of nasolabial-fold improvement
- Smooth thread (thread without protrusions): mainly aimed at promoting collagen production. The lift effect is limited, and it may be insufficient for the deep grooves of nasolabial folds
- 3D bidirectional barbed thread: a type with anchoring power in multiple directions, for which an effect on nasolabial folds can be expected in some cases
The effect of insertion angle
Whether you insert the thread diagonally upward toward the cheekbone or toward the temple changes the vector of the lift (the direction and orientation of the force). To improve nasolabial folds,a vector that lifts in a direction nearly perpendicular to the nasolabial grooveis considered important.
In other words, even with the same "thread lift," the effect on nasolabial folds differs greatly depending on the thread used and the insertion design. From clinical experience, we have seen many cases where such technical factors create differences in results.
The overall effect and duration of thread lifts as seen from the evidence
Regarding the effect of thread lifts in general, a comprehensive review published in 2021 is a useful reference. This paper analyzes multiple clinical studies across the board and organizes the evidence on thread lifts.
Atiyeh et al. (2021)'s review states that thread liftsmild to moderate sagginghave reported cases of improvement for, while for severe sagging, surgicalfaceliftis still considered superior (DOI: 10.1097/PRS.0000000000007890).
There is also interesting data on duration. It varies by material and thread type, but according toAtiyeh et al. (2021)'s review,an effect generally lasting about 6 to 18 monthsis reported (DOI: 10.1097/PRS.0000000000007890). However, individual differences are large, and results vary with skin type, the degree of sagging, the number of threads, and the operator's skill.
Be cautious of procedures that claim to "last forever." Based on the current evidence, thread lifts are positioned as procedures premised on periodic maintenance.
Risks and limits you should know—the thread lift as a "double-edged sword"
While expecting the effect of thread lifts, it is also important to honestly know the risks. The comprehensive review by Tong L et al. (2019) describes thread lifts as a "double-edged suture" and analyzes both the effects and the risks (DOI: 10.1097/DSS.0000000000001921).
The main reported risks
- Thread exposure / visibility through the skin: in areas with thin skin, the thread may show through or protrude
- Left-right asymmetry: a subtle difference in insertion position or tension may cause left-right asymmetry
- Infection: although the frequency is low, the risk of bacterial infection from the insertion site is not zero
- Tightness / a feeling of discomfort: for a while after the procedure, you may feel discomfort when moving your expression
- Limits of the effect: for severe sagging or a lot of excess skin, there is a limit to improvement with threads alone
However, this review also shows thatthe frequency of serious complications is relatively low. After correctly understanding the risks, it is important to consult a doctor about whether the procedure suits the degree of your sagging.
5 checkpoints when considering a thread lift for nasolabial folds
Based on the evidence so far, we summarize the points you'll want to confirm when considering a thread lift to improve nasolabial folds.
- Is the degree of sagging mild to moderate?: if it is severe, discuss it including other options
- Confirm the type of thread used: barbed or smooth? Threads with lifting power are suited to nasolabial folds
- Receive an explanation of the insertion design: how many threads and in which direction. Is the vector design suited to improving nasolabial folds?
- Ask about the expected duration: half a year to a year and a half is typical. Judge facilities that promise "permanent" carefully
- Is the risk explanation thorough?: do they properly explain not only the effect but also the possible problems?
Whether a thread lift suits your nasolabial folds differs by each person's facial structure, skin type, and the goal they seek. We recommend not judging by internet information alone but receiving an in-person examination.

Summary — make a realistic choice based on research data
It has been confirmed, through research and comprehensive reviews, that there are certain reported cases of nasolabial-fold improvement from thread lifts. In particular, studies using barbed threads have reported cases in which improvement was seen in the depth of nasolabial folds.
On the other hand, it is also a fact shown by the evidence that results differ greatly depending on the type of thread, the insertion angle, and the degree of sagging, and that the duration is limited and varies between individuals.
Not over-expecting the effect, and aiming for realistic improvement—that is the key to raising satisfaction after the procedure.
