What It Is
Trapezius Botox, Explained
Your trapezius is the broad muscle that runs from the base of your skull, across the tops of your shoulders, and down your upper back. When it's chronically overworked, from desk posture, stress, heavy training, or simply carrying your tension up high, it stays contracted, which drives shoulder tightness, neck stiffness, and headaches, and can build a bulky, elevated shoulder line.
Trap Tox relaxes that muscle with precisely placed Botox or Dysport. It does two things at once: it releases the chronic tension (real, physical relief), and, as the muscle softens, it visually lengthens the neck and sculpts the shoulder line. That aesthetic result is why the treatment went viral as “Barbie Botox.” Most patients come for one benefit and are happy to get both.
Why Patients Book It
Relief You Feel. A Line You See.
Relieves shoulder & neck tension
Relaxes a chronically tight, overworked trapezius, the desk-and-stress tension so many people carry in their upper back and shoulders.
Eases tension headaches
When tight traps are driving headaches that start at the base of the skull, relaxing the muscle can reduce their frequency and intensity.
Longer, more elegant neckline
Softening a bulky or raised shoulder line visually lengthens the neck and sculpts the shoulder silhouette, the look behind “Barbie Botox.”
Built for desk workers & lifters
A favorite of two groups: people who live with shoulder tension at a desk, and gym-goers whose traps have overdeveloped. We dose to your goals.

Trap Tox FAQ
Questions About Trap Tox
Trap Tox (also called trapezius Botox or “Barbie Botox”) is the injection of Botox or Dysport into the trapezius, the large muscle running from the base of your skull across your shoulders and down your upper back. It relaxes chronic tension, can ease tension headaches, and softens a bulky or raised shoulder line for a longer, more elegant neck.
“Barbie Botox” is the viral nickname for Trap Tox used for its aesthetic effect, slimming and relaxing the trapezius to create a longer neckline and more sculpted shoulders. It is the exact same treatment; only the goal (aesthetic vs. tension relief) differs, and most patients get both.
At Banyan & Bamboo, injectables are priced per unit, $14.50 per unit for Botox and $5.50 per unit for Dysport, so your total depends on your unit count. Trap Tox typically uses 15–30 units per side. Brittany gives you an exact unit count and price before anything is injected, so there are no surprises.
Typically 15–30 units per side, depending on the size and strength of your trapezius and your goals. Larger, more developed muscles need more. We assess your anatomy in person and dose conservatively.
About 3–5 months. With repeat treatment the muscle tends to calm down over time, so many patients find they need fewer units and less frequent visits.
You’ll usually start to feel the muscle relax within 5–7 days, with the full effect settling over about two weeks. Aesthetic changes to the shoulder line develop gradually over several weeks.
It can. By easing the constant upward pull of an overactive trapezius, many patients feel their shoulders sit more relaxed and their posture improve. It supports better posture rather than forcing it.
It relaxes the muscle’s resting tension, not your ability to train. Most patients continue their normal workouts and simply notice less constant traps-up tension. If you’re a serious lifter, tell us your goals and we’ll dose accordingly so you keep function while getting relief.
