The most frequent question in nasolabial fold consultations is, "Is Filler better, or is Juvelook better?"
The two are not related in that they produce the same results with different values. Their modes of operation are entirely different.
Therefore, instead of asking which is better, you should consider which one is suitable for your condition.
Please take just one minute to read this.
What the Two Methods Do
Filler directly fills in sunken areas by injecting a substance. Since the shape changes the moment it is injected, the change is immediately visible.
Collagen stimulation methods are different. The substance itself does not create volume; instead, it stimulates the tissue to produce collagen on its own. Therefore, changes appear gradually over time.
In Summary
| Immediate Filling Method | Collagen Stimulation Method | |
|---|---|---|
| Time of Change | Immediately after procedure | Gradually over several weeks |
| Source of Volume | Injected substance | Collagen produced by tissue |
| Reversibility | Relatively possible | Absorbs over time |
| Best Suited For | Distinctly sunken specific areas | Overall thinning and loss of elasticity |
Why Filler for Nasolabial Folds Requires Careful Consideration
The area around the nasolabial folds is close to where blood vessels pass. The results can vary greatly depending on which layer and how much is injected, and injecting too much can lead to an unnatural appearance.
Also, the cause of deep nasolabial folds is often not just the hollowness of that area. If the deepness of the fold is due to the weight of the cheek area descending and creating a crease, then an approach that only fills along the line may be misdirected.
In such cases, it may be necessary to consider addressing the layer where the weight is concentrated.
Collagen Stimulation Methods Also Have Side Effects
It cannot be definitively stated that methods that gradually create volume are completely safe.
Swelling, bruising, and nodule formation may occur due to the injection itself, and the surface may feel uneven depending on which layer and how much was injected.
The degree and duration of these effects can vary from person to person, and it is safest to consult with medical staff before proceeding.
Three Factors That Determine the Choice
First, timing. If a specific event is approaching, the method that shows immediate changes may be more suitable.
Second, the extent of the hollowness. This depends on whether a specific area is distinctly sunken or if there is an overall loss of elasticity.
Third, the layer of the cause. If the issue is due to the crease line itself, or if it's a result of the weight from above descending, a filling approach alone may not be sufficient.
When Both Are Performed Together
The two methods can also be used together, either on the same day or in sequence.
However, rather than simply adding them indiscriminately, they are combined after determining what is lacking in which area. Overlapping multiple methods in the same area can lead to excessive volume or an uneven surface.

Frequently Asked Questions
Which one looks more natural?
It depends more on the design than the method. The immediate filling method can look natural if the appropriate amount is maintained, and the collagen stimulation method can look unnatural if overdone.
When do results from the collagen stimulation method become visible?
They do not appear immediately. Changes occur gradually over several weeks, so it is too early to judge during that period.
Isn't it enough to just fill in nasolabial folds?
That is true if the cause is hollowness in that area. However, if the deepness of the line is due to the upper tissue descending, simply filling it may be the wrong approach.
Can side effects be reversed?
It depends on the method. In some cases, there is an option to reverse it, while in others, it may be necessary to wait for it to absorb over time.
What should I confirm during a consultation?
Confirming three things—where and how much hollowness there is, whether the weight from above is also a contributing factor, and when your schedule is—can help determine the direction.
