Shoulder (Trapezius) Botox in Myeongdong, Seoul
A bulky upper trapezius makes the neck look shorter and the shoulders sloped. Relaxing it lets the muscle slim down for a longer, more graceful neck line, and often less shoulder tension.
Quick answer
Shoulder Botox, also called trapezius or ‘Barbie’ Botox, relaxes the upper trapezius between the neck and shoulder. The muscle gradually slims, so the neck looks longer and the shoulder line straighter, and many people feel less tension. A treatment often uses about 25–50 units per side, results appear over 4–8 weeks and last about 4–6 months.
What is shoulder Botox?
The upper trapezius lifts and braces the shoulders. Desk work, stress and carrying bags can make it thick and tense. When it relaxes, it shrinks slowly, which changes the outline between neck and shoulder. It is a contour treatment, not a cure for neck pain, although tension often feels lighter.
Who is it for?
- A short-looking neck or sloped, bulky upper shoulders.
- Shoulder tightness from desk work or stress.
- Less suitable for people doing heavy overhead lifting or competitive sport.
