Hello, this is Relieve Clinic.

Among the procedures performed in dermatology, filler treatments are a representative option when it comes to changing facial impressions in a short period of time.

Without surgery, they can improve facial contours and restore lost volume, which is why they are highly satisfying procedures.

In particular, as fuller lips have become more preferred recently, more and more people are considering lip filler treatment.

At this point, one of the most frequently asked questions is, “How long do lip fillers last?”

It is only natural to wonder how long the effect will last from the moment you decide to get lip fillers, and how the shape will change over time.

In general, lip fillers last about 6 to 12 months.

Of course, this can vary depending on individual skin condition, the type of filler used, and lifestyle habits.

Among these, the factor with the greatest influence is the filler’s “formulation.”

Lip filler duration: differences in formulation?

Depending on the formulation, fillers differ in the treatment areas and the roles they play.

For example, fillers used to improve fine lines around the eyes and mouth need to be thin and soft so they can spread widely.

On the other hand, lip fillers need to create volume, so a firmer formulation is used.

In particular, the lips are an area that moves continuously due to eating and facial expressions, so it is important to choose a filler that does not spread easily and can maintain its shape.

However, although firmer fillers last longer and make volume adjustment easier, they may look unnatural if they are not injected into the correct position.

To achieve a natural and harmonious result, there are several points that need to be considered.

For lip fillers, naturalness comes first.

If you ask what the most important thing is when performing lip filler treatment,

I usually answer, “naturalness.”

And to achieve a natural result, detailed design is essential above all else.

Lip filler treatment is one of the more difficult procedures.

That is because the area moves a lot, and if the design is excessive or the filler is injected too much, asymmetry can become more severe or there is a risk that the filler will migrate.

Therefore, the most important factor determining the outcome of lip fillers is setting the appropriate amount.

Because the lips have a three-dimensional structure, volume must be precisely adjusted from various angles to achieve a natural result without looking overdone.

In particular, unlike the relatively flat forehead, the lips are small and protruding, so both the front and side views must be considered.

In areas like the forehead where the injection area is broad, a small error may not have a major impact, but in the lips even a slight change is easily visible.

So if even a small error occurs, it can easily give an artificial impression.

Finding the right amount is by no means a simple process.

In other words, there is no room for luck in filler treatment.

So then, what should you look for when choosing a medical provider to get lip fillers properly?

Lip filler duration, results shaped by differences in detail

What I emphasize again is that filler treatment requires detailed design with the medical staff.

During the duration of lip fillers, many people surprisingly choose to dissolve the filler.

Most often, this is because of issues such as “asymmetry in the corners of the mouth” or an “unnatural mouth shape.”

To prevent these problems, a customized design should be planned while considering the following factors.

  1. Overall harmony of the lower face

  2. Horizontal and vertical lip volume

  3. Direction of the corners of the mouth

  4. Degree of asymmetry

  5. Balance with the eyes and nose

Especially, the overall impression can change greatly depending on the ratio between the upper and lower lips.

The most ideal ratio is about 1:1.5 to 1:1.7, and generally it looks more stable and harmonious when the lower lip has slightly more volume than the upper lip.

Many medical professionals design lip fillers according to this standard.

However, this ratio does not apply uniformly to everyone.

That is because slight adjustments may be made depending on the individual’s facial shape and lip structure.

For example, for people whose face is longer vertically than it is wide, injecting the lip line in a thinner and longer shape may look more harmonious.

On the other hand, for people with a generally round face, emphasizing the volume of the lower lip can help create a fuller look.

In addition, the ratio is adjusted while sufficiently considering each customer’s desired treatment direction.

Sometimes customers directly find and show the design they want.

It may depend on the medical professional, but if you clearly present the direction you want for the procedure in this way, it can certainly help with the design.

However, excessive design may not be good for long-term satisfaction after the procedure, so caution is needed.

One more thing to add: to carefully examine all of these aspects, the time each medical professional must devote to each customer inevitably becomes longer.

In other words, this is a process that is difficult to carry out in so-called “factory-style dermatology clinics,” where procedures are performed by securing as many customers as possible in a limited amount of time.

Once a filler procedure is performed, it generally takes an average of 6 to 12 months for all of the active ingredients in the body to be absorbed.

Since the results maintained during that period are something you must fully accept yourself, please make a careful decision.

So far, I have summarized information that may be helpful for those preparing for lip fillers, including how long lip fillers last.

In addition to the points discussed in today’s post, I will finish by attaching an article that reflects my treatment philosophy and goes into more detail about the criteria for choosing a dermatology clinic for lip fillers.

I hope this post was helpful to those considering filler treatment. Thank you for reading this long post.
