Barbie Botox (Trapezius Slimming Treatment)
Barbie Botox is a specialised aesthetic treatment that targets the trapezius muscles—the large muscles extending from the base of the skull down to the shoulders. In many individuals, these muscles become bulky due to genetics, stress-induced tension, poor posture, or regular resistance training. This can result in a wider, more masculine shoulder profile and contribute to chronic neck and shoulder discomfort.
By carefully injecting botulinum toxin into the trapezius muscles, Barbie Botox softens the shoulder contour, elongates the appearance of the neck, and reduces muscle tension—delivering both aesthetic and therapeutic benefits. The result is a more refined, elegant silhouette, reminiscent of the sculpted proportions commonly associated with a “Barbie” neckline.


This treatment is ideal for individuals who:
• Wish to achieve a slimmer, more feminine shoulder contour
• Desire a longer, more elegant neckline without surgery
• Experience chronic tension in the neck and shoulders from stress or posture
• Have trapezius hypertrophy due to weight training or repetitive upper body movement
• Are looking for a non-surgical body contouring option with minimal downtime
How Does the Treatment Work?
Barbie Botox works by injecting botulinum toxin into the upper trapezius muscles, blocking nerve signals that cause muscle contraction. As the muscle relaxes, it gradually reduces in size and tension.
This leads to:
• A slimmer, softer shoulder line
• A visibly elongated neck and upper body profile
• Relief from muscular tension, stiffness, or stress-related discomfort
• A postural improvement as overactive trapezius activity often contributes to rounded shoulders

Injection Points for Barbie Botox:
• Injections are placed along the bulk of the upper trapezius on both sides of the neck and shoulders
• The exact number of points and units is customised based on muscle size, strength, and treatment goals
• This procedure may be paired with jawline or neck treatments for full upper-body balance

Frequently Asked Questions
What is Barbie Botox?
Barbie Botox refers to the targeted use of botulinum toxin in the trapezius muscles (trap tox), designed to create a longer, more elegant neck, a softened shoulder profile, and improved posture. Popularised by its “Barbie-like” effect, this procedure is both cosmetic and functional, reducing muscle bulk and tension in the upper back region.
How Does Barbie Botox Work?
Botulinum toxin (a neuromodulator) blocks nerve signals to the targeted trapezius muscle, reducing overactivity. The result is muscular relaxation, which leads to visible slimming of the shoulders and elongation of the neck. Additionally, it can reduce chronic tension, headaches, or shoulder discomfort in some patients.
