In shoulder line consultations, there is a particularly wide variation in reviews.
"Definitely changed" and "not so good" are attached to the same procedure name.
This is because even if the shoulder concerns appear to be the same, the causes are divided into two.
Please take just 1 minute to read.
Two Causes
| Cause | How it Appears | Approach |
|---|---|---|
| Lack of volume at the shoulder tip | The line from the collarbone to the shoulder is flat | Adding volume |
| Developed trapezius muscle | The line from the neck to the shoulder is raised | Reducing muscle volume |
The two causes differ in the areas and methods of approach.
If there is a lack of volume and only the muscle is reduced, the shoulders may look narrower and weaker, and if the trapezius muscle is thick and only volume is added, the whole may look bulkier.
This is the first point where satisfaction varies.

Often Mixed Cases
In reality, it is common for both to occur together.
The trapezius muscle may be developed while there is a lack of volume at the shoulder tip.
In this case, the order is important.
It is natural to first reduce muscle volume to create a baseline for the line, and then add volume to the remaining empty space.
If done in reverse, as the muscle shrinks, the previously filled volume may appear misplaced.
(※ Effects and reactions may vary depending on the individual's skin condition, and suitability for the procedure is determined through consultation with medical staff.)

How to Estimate Yourself
While an accurate judgment is made during consultation, there are signs to refer to.
- If the side of the neck is raised even when the shoulders are relaxed, it's more about muscle.
- If the shoulder tip appears sunken inward when the arms are down, it's more about volume.
- If bag straps slide off easily, it's more about volume.
- If the shoulders are often stiff and sore, it's more about muscle.
If two or three of these overlap, you can consider it a mixed case.

Location Determines the Result
Especially for adding volume, where it is injected determines the line.
Even with the same volume, if the location is too far inward, the shoulders may not look wide, and if it's too far outward, it may look unnatural.
The same applies to the muscle area; the results vary depending on the area and depth.
You can check if the consultation explains where and how to divide the injection points.


Frequently Asked Questions
Why do reviews for shoulder line procedures vary so much?
Satisfaction varies greatly because the same procedure is sometimes applied to different causes, such as lack of volume and developed trapezius muscle.
Do I need to receive both?
It is common for both to be present. However, there is an order, and it is natural to first address muscle volume and then add volume.
How can I estimate my cause?
You can refer to whether the side of your neck is raised when relaxed, whether your shoulder tip appears sunken when your arms are down, or if bag straps slide off.
Is location that important?
Even with the same volume, the line changes if the injection point is different. You can check if the consultation explains where and how to divide the injection points.
What are the reactions after the procedure?
Temporary swelling, bruising, and soreness may occur. The degree and duration vary from person to person.
Recovery and Downtime: Area Characteristics
Since the shoulders are an area pressed by bags or clothes, it is advisable to reduce pressure for a few days.
For muscle-related procedures, it takes time for changes to appear, and for volume-related procedures, the shape becomes visible after the swelling subsides.
If both procedures were performed together, an accurate assessment of the progress can be made a few weeks later.
How is the Cost Structured?
The cost is not determined by volume or units alone.
It varies depending on which of the two procedures is performed, whether they are combined, and the extent of the area treated.
An accurate cost will be provided after a consultation to confirm the cause.
