Creating a Beautiful Neck–Shoulder–Arm Line: The Medical Approach Behind SANA’s Silhouette2026.02.27
A beautifully defined upper body is not created by arm shape alone.
The neck–shoulder–arm line depends on bone position, muscle balance, and surgical design.
This is exactly why SANA’s upper body looks so elegant.
■ The key lies in the position of the shoulder blade
For women, the ideal scapula position is:
- Not elevated upward (×)
- But drawn inward toward the spine (✓)
Two muscles determine this:
1. Levator scapulae (red)
Pulls the scapula upward → creates bulky shoulders and a thick-looking neck.
2. Rhomboids (blue)
Pull the scapula inward → creates a slimmer, feminine shoulder line.

■ Why arm liposuction alone is not enough
Even if the arms become thinner, the upper body will not look elegant if:
- The levator scapulae is overactive
- The scapula is lifted upward
- The shoulder frame looks wide
To achieve a truly beautiful line,
arm contour + shoulder position must be corrected together.
■ The AVAN TOKYO approach to a truly refined upper body
① Full upper arm liposuction
Creates a clean, sharp line from every angle—front, side, and back.

② Botox to the levator scapulae
- Reduces unnecessary shoulder bulk
- Makes the neck look longer
- Improves the clavicle and décolleté line
- Creates the “slim shoulder” effect
③ Training to activate the rhomboids
Improves posture and brings the scapula inward for long-term maintenance.
By combining these three elements, we can reproduce a slim and elegant upper body like SANA’s.
■ For anyone who wants slimmer arms and a clean upper body line
If you experience:
- Thick-looking upper arms
- Bulky shoulders
- A short-looking neck
- Difficulty achieving a “slim” silhouette
Then a combined approach—
arm liposuction + levator scapulae Botox + posture correction
can dramatically change your appearance.
■ Conclusion: A beautiful upper body is designed, not guessed
True beauty comes from understanding:
- Which fat to remove
- Which muscle to relax
- Which muscle to activate
