Hongdae Trapezius Botox, if you have hesitated to wear clothes that reveal your neckline

September 29, 2026

Hello.

I am Dr. Dong-young Kim, Director of Cleor Clinic Hongdae Branch.

On days when you carry a heavy bag all day,

you may notice your shoulders looking particularly raised when you stand in front of a mirror in the evening.

Even after putting the bag down and trying to relax your shoulders, they seem to return to the same position shortly after,

and you may even feel as if your shoulders are being pulled up when you turn your neck from side to side.

These concerns often arise when choosing clothes.

This is because when you wear clothes that reveal your neckline, the shoulder line is the first thing that catches the eye.

If your shoulders look raised, it can give the impression of a shorter neck, even if your actual neck length is the same.

This is a concern that you may face more often if you spend long hours sitting and frequently look down at screens.

Today, I will explain what the Hongdae Trapezius Botox is, why the muscles on your shoulders remain in a state of constant tension,

and how the toxin works at that point, step by step.

What is Hongdae Trapezius Botox

👉 Hongdae Trapezius Botox is a treatment that aims to lower the constant tension in the upper part of the trapezius muscle, which lifts the shoulders,

thereby addressing both the shoulder line and the neckline.

The trapezius is a triangular muscle that spreads widely from the back of the neck, across the shoulders, and down to the upper back.

It is largely divided into upper, middle, and lower fibers, each with different functions.

The upper fibers are responsible for shrugging the shoulders and supporting the neck,

while the middle and lower fibers are used to pull the shoulder blades inward or downward.

The area most closely related to the impression of your shoulder line is the upper fibers.

This is the thick part you can feel where the neck and shoulders meet,

and this is the range covered by the Hongdae Trapezius Botox.

However, there is not just one reason why shoulders may look broad or high.

The shape of the skeletal structure, muscle tension and volume, and posture habits all play a role in varying degrees,

and the part that toxin-based treatments address is the muscle component.

Toxin is a protein derived from botulinum toxin that acts on the process

where acetylcholine, a substance that transmits contraction commands from nerve endings to muscles, is released.

When the amount of transmitted commands is reduced, the degree to which the muscle pulls itself also decreases,

which is the basis for using this property when treating the muscles on the shoulders.

Strengths of Hongdae Trapezius Botox

👉 The greatest strength of Hongdae Trapezius Botox lies in targeting postural tension that never fully relaxes.

First, it directly addresses the state where you cannot relax even if you try.

The trapezius muscle on the shoulders is always supporting the weight of the arms,

so it does not fully rest even when you are standing still.

When you add carrying a bag or looking down at a screen,

the muscle remains in a state of continuous low-level contraction.

This is why your shoulders rise again a few seconds after you consciously lower them.

Toxin works by reducing the commands from the nerves to the muscles, thereby relieving this constant tension.While stretching or massage is an approach that relaxes muscles from the outside,

this is an approach that lowers the intensity at the stage where the commands are received.

Second, it involves a distribution logic that divides the range and depth.

The trapezius is much larger and thicker than facial muscles and is layered,

so a method of focusing on a single point is not appropriate.

We divide the section from where the neck and shoulders meet to the outer shoulder,

and adjust the depth of the treatment according to the muscle thickness.

There is one more condition: the upper fibers of the trapezius

also have the function of rotating the shoulder blades when lifting the arms above the head.

Since this function is necessary for daily movements, it must be preserved,

so we select and target the area that most significantly affects the impression of the shoulder line.This is why the distribution is not the same for every shoulder concern.

Third, it aims for a visual change where the neckline appears longer without actually changing the neck length.

The standard people use to perceive neck length

is the distance from under the chin to the shoulder line.

When the shoulder line is lowered, this distance is perceived as longer even if the neck bone length remains the same,

and the angle where the neck and shoulders meet becomes gentler, changing the impression to a continuous line.

This is also why we often hear that the difference is most noticeable when wearing clothes that reveal the neckline.

Working Principle of Hongdae Trapezius Botox

👉 The principle of Hongdae Trapezius Botox is to lower the tension maintained by continuous contraction at the signal stage,

leading to changes in usage and volume.

First, there is the process where continuous contraction hardens into tension.

The longer a muscle is used, the longer it takes to return to a resting state.

If the habit of supporting the weight of a bag with your shoulders and looking down at a screen is repeated every day,the upper trapezius maintains a low level of contraction without any period of complete relaxation.

Once this state becomes the default,

even if you think you have relaxed, a certain level of tension actually remains.

Next is the stage where the signal is reduced.

For muscle fibers to receive a contraction command, acetylcholine must be released from the nerve endings,

and the toxin acts on the proteins involved in this release process to reduce the amount transmitted.

When the amount of commands is reduced, the tension the muscle maintained itself also decreases,

creating time for relaxation in areas that were not fully relaxing.

Finally, when usage decreases, changes in volume follow.

Since muscle is a tissue that maintains its thickness as much as it is used,

if the period of low usage continues, it is reported that the volume and tension of the thick area change.

This change tends to appear over time rather than being completed within a few days,

and the degree of feeling it varies depending on muscle thickness, posture habits, and daily activity levels.

Who is Hongdae Trapezius Botox suitable for?

Those who feel their neck looks short because their shoulders are always raised

Those who have continuous shoulder tension due to heavy bags or long hours of desk workThose who are concerned about their shoulder line when wearing clothes that reveal the neckline

Those who feel a firm, thick area when touching the top of their shoulders

Those who feel that stretching or massage only provides temporary relief

Types of Hongdae Botox

👉 Toxin treatments are approached differently depending on the size and function of the muscle being treated,

and the trapezius belongs to the category of large muscles where both volume and tension are considered.

The appropriate range depends on muscle thickness, left-right balance, and posture habits,

so we determine the direction after checking during the consultation.

Side effects and things to know in advance about Hongdae Trapezius Botox

👉 Most things to know in advance about Hongdae Trapezius Botox are temporary reactions, and it is reported that they often subside over time.

If you frequently lift heavy objects or do exercises that use your shoulders a lot,

it is better to mention it during your consultation.

The distribution direction will be adjusted according to your usage patterns.

  • ⚠️ Precautions before and after Hongdae Trapezius Botox

  • ❓ Frequently Asked Questions (FAQ)

  • Q. How is Hongdae Trapezius Botox different from massage or stretching?

  • A. Massage and stretching are approaches that relax already contracted muscles from the outside.

  • Toxin is a method that lowers the amount of contraction commands sent from the nerves to the muscles,

so it differs in that it lowers tension at the stage where the command is received.

Q. Is there any difficulty in lifting my arms after receiving Hongdae Trapezius Botox?

A. The upper trapezius also has the function of rotating the shoulder blades when lifting the arms above the head, so we plan the treatment to preserve this function.

You may feel less strength initially, but it usually returns to its original sensation over time.

Q. Can people who do weight training receive Hongdae Trapezius Botox?

A. If you do exercises that use your shoulders a lot, we first check your usage patterns.

Since the sensation can vary depending on the amount of muscle usage,

it is easier to plan the distribution if you tell us the type and frequency of your exercise during the consultation.

Q. Does Hongdae Trapezius Botox also change forward head posture?

A. It is not a treatment that changes the posture itself.

Since it is involved in lowering the tension of the muscles on the shoulders, it is recommended to continue managing lifestyle habits such as screen height or bag weight.

Q. Does the neckline really look different after Hongdae Trapezius Botox?

A. Since neck length is perceived as the distance from under the chin to the shoulder line,

lowering the shoulder line leads to an impression of a longer neck even if the length is the same.

However, neck wrinkles or skin conditions are different areas, so they are examined separately.

Q. Is Hongdae Trapezius Botox the same method as facial Botox?

A. The working principle is the same, but the approach differs because the size and thickness of the muscles treated are different.

Since the trapezius is a large, layered muscle, the distribution is planned by dividing the range and depth.

Hongdae Trapezius Botox is a treatment that lowers the tension that the muscles on the shoulders could not fully release, at the stage of commands from the nerves to the muscles.

It is an option for those who have felt that external relaxation methods only provided temporary relief and are looking for a different approach.

Because the trapezius is a large and thick muscle, the distribution is planned by dividing the range and depth, and the function of lifting the arms is preserved.

At Cleor Clinic Hongdae Branch, we check the muscle thickness, left-right balance, and posture habits during the consultation to determine if it is a suitable direction for you.

If you are also considering other muscle areas like calf Botox or body Botox, we may plan the treatment by dividing the ranges.

If you felt that your shoulders remained raised even after putting your bag down,
