One of the most elegant features shared by many beautiful women is a defined sternocleidomastoid line — that graceful contour running from the jaw down to the collarbone.

Even if the face or arms are slimmed with liposuction, a thick neck or prominent shoulder can make the upper body appear bulky or less refined.

🧠 The Two Muscles That Shape the Neck and Shoulder Line

1. Trapezius Muscle
    A dominant trapezius can make the shoulders look broad and short. Injecting botulinum toxin into this muscle relaxes the tension, creating a more feminine slope from the neck to the shoulder.
2. Sternocleidomastoid Muscle (SCM)
    This muscle defines the elegant “neck line” just beneath the jaw. When overdeveloped, it can make the neck appear thick or tense. Botox in this area helps smooth and elongate the neck, refining the face-to-neck transition.

💉 Treatment Details

• Trapezius Botox: typically 100–300 units, depending on body size.
• SCM Botox: around 30–100 units.
  Precise injection depth and placement are crucial — too much relaxation can lead to posture imbalance or unnatural results.

💫 Synergy with Arm and Facial Liposuction

The most beautiful upper body contour comes from addressing both fat volume and muscle balance.

• Arm Liposuction: reduces outer arm bulk, emphasizing the shoulder’s natural curve.
• Facial Liposuction (cheeks/jawline): sharpens facial definition, enhancing the SCM line.

When combined with trapezius and SCM Botox, the result is a slender, elegant “swan neck” and balanced upper body.
