Shoulder Slimming / Trap Tox
Trap Tox, also called Barbie Botox or trapezius Botox, is the injection of Botox into the upper trapezius muscles. By relaxing and softening those muscles, the neck appears longer, the shoulders sit lower, and the chronic tension carried by desk work, stress, and screens is meaningfully reduced.
The trapezius is a large, kite-shaped muscle that spans from the base of the skull, across the top of the shoulder, and down between the shoulder blades. The upper portion, the part that sits between the neck and the shoulder, is the part that bulks up with stress, posture, and heavy lifting, and the part that produces the “hunched-up,” tense look so many patients describe.
Trap Tox, the popular name for trapezius Botox, uses targeted injections of Botox (botulinum toxin type A) placed into the upper trapezius. Over several weeks, the muscle relaxes and reduces in bulk. The neck-to-shoulder transition becomes more graceful, the shoulders drop into a more natural position, and the chronic, low-grade tension that radiates up into the base of the skull eases.
Patients seek Trap Tox for two reasons that almost always overlap. The cosmetic motivation is the look the treatment is named for: a longer, more elegant neckline and a softer shoulder slope, the look popularly called Barbie Botox. The functional motivation is relief from chronic upper-trap tension, tension headaches that start at the base of the skull, shoulder stiffness from desk work and phone use, and jaw clenching that travels into the neck.
In practice, most patients report the functional change first, less tightness, easier sleep, fewer afternoon headaches, before the cosmetic change becomes obvious. The visual change is real, but it is gradual. Expect early relief in feeling, with visible refinement of the contour over four to six weeks.
The trapezius is a large, deep muscle, and a Trap Tox treatment uses substantially more units than a typical facial Botox visit. Dr. Boxrud uses Botox exclusively for Trap Tox, the most extensively studied neuromodulator with the longest track record at the larger doses this region requires.
The trapezius is palpated, the bulkiest part of the muscle is mapped, and dosing is calibrated to the actual muscle, not to a default unit count copied from social media. Conservative, anatomic dosing produces the look without compromising shoulder function. Patients across Los Angeles, Santa Monica, and Beverly Hills see her for the carefully dosed version of this very-popular treatment.

Is Trap Tox really the same as Barbie Botox?
Yes. Trap Tox, Barbie Botox, trapezius Botox, shoulder Botox, and shoulder slimming are different names for the same treatment, the injection of botulinum toxin into the upper trapezius. The “Barbie” nickname comes from the long-necked, narrow-shouldered look it produces.
How long until I see results?
Most patients feel relief from tension within 1 to 2 weeks. Visible contour change, the slimmer shoulder line and longer neck, becomes apparent at 4 to 6 weeks and continues to refine through 2 to 3 months.
How long does Trap Tox last?
Trap Tox results typically last 3 to 4 months in the trapezius. Because the dose here is larger than facial treatment, many patients find a steady three-times-a-year rhythm comfortable, with the visible contour often holding slightly longer between visits as treatments continue.
Does Trap Tox help with tension headaches?
Often, yes. Tension-type headaches that begin at the base of the skull and radiate up are strongly associated with chronic upper-trap tightness. Relaxing the trapezius commonly relieves them. It is not a substitute for evaluation of migraine or cervical spine disease, which are different problems.
Will I lose strength in my shoulders?
Not in normal daily activity, when dosing is conservative and anatomic. Patients who lift heavy weights or train at a high level should discuss the timing of treatment around competition or peak training; very high doses are not appropriate for serious upper-body athletes.
Are there any side effects?
The most common are mild bruising at injection sites and brief soreness for a day or two. Rarely, patients describe a transient sense of fatigue in the shoulders during the first weeks. Serious adverse events are uncommon with appropriate dosing and placement.
Can it be combined with other Botox treatments?
Yes. Trap Tox is often combined in the same visit with upper-face Botox, a Nefertiti lift along the jawline and neck, or masseter Botox for jaw slimming, so that the neck, shoulders, and face all read in proportion.
