Trap Botox at InjectCo is priced at $7.77 per unit with the InjectCo membership ($24.99/month), or $12 per unit without it, so your total depends on how many units your injector recommends. As an example, 60 units is $720 and 100 units is $1,200. Cosmetic trapezius Botox is off-label and is not billed to insurance.

Medical disclaimer: This article is for education only and does not replace medical advice. Individual results vary. Cosmetic trapezius Botox is an off-label use of botulinum toxin. If you have blurred vision, drooping eyelids, trouble swallowing, trouble breathing, muscle weakness, or other severe symptoms after an injection, seek urgent medical care.
Traptox at InjectCo is priced by the unit: Botox $7.77 per unit with membership ($24.99/month), or $12 per unit without it. Because the trapezius is a large muscle, treating both shoulders takes more units than most facial areas, so the total is higher.
| Total Botox units (both shoulders) | Cost at $12 per unit |
|---|---|
| 60 | $720 |
| 80 | $960 |
| 100 | $1,200 |
These are arithmetic examples, not treatment plans. Your nurse injector recommends a unit count after assessing your muscle size, strength, symmetry, and goals, and you’ll see the total before anything is injected.
Using Botox to slim the trapezius is off-label. The BOTOX prescribing information lists cervical dystonia, a neck muscle disorder, as a medical use, but cosmetic shoulder contouring has no labeled dose. The closest guide is what published studies used:
| Study | Product and dose | Cost of that dose in Botox at $7.77 per unit with the InjectCo membership ($24.99/month), or $12 per unit without it |
|---|---|---|
| J Orthop Surg Res, 2021: 20 women | Botox, 50 units per side (100 total), five points per side, ultrasound-guided | $1,200 |
| J Cutan Aesthet Surg, 2022: 20 volunteers | 30 units per side, Botox on one shoulder and Xeomin on the other | $720 for 60 Botox units |
| Aesthetic Plast Surg, 2026: 20 women | 40 or 80 units of letibotulinumtoxinA, a different product, at 10 injection points | Not convertible |
In the 2026 trial, the 40-unit and 80-unit groups showed no difference in results. That’s one small study, but it’s a useful reminder that more units don’t automatically mean a better outcome.
Units from Xeomin, Dysport, and Letybo are not interchangeable with Botox units, so a dose from one product can’t be priced as Botox. For how trapezius dosing compares with other areas, see Botox units by area.
Ask for an estimate that states the product, total units, per-unit price, and total.
See your unit count before treatment.

Cosmetic trap Botox for shoulder slimming is not billed to insurance. InjectCo does not bill insurance, and Traptox appointments are self-pay cosmetic services.
Botulinum toxin does have a separate medical pathway for certain diagnosed conditions. The BOTOX prescribing information lists cervical dystonia in adults as an approved use. That treatment requires evaluation, diagnosis, and treatment planning by an appropriate physician, and a cosmetic med spa appointment can’t substitute for it.
Neck and shoulder pain on their own usually don’t qualify. Aetna’s published botulinum toxin policy, for example, lists chronic neck pain and shoulder pain as experimental, investigational, or unproven uses.
If pain is your main reason for considering treatment, see a physician first. You may need medical evaluation, physical therapy, or other care before a cosmetic service makes sense.
Results are temporary, but the studies suggest they can last longer in the trapezius than many people expect:
These were small studies with set doses and ultrasound guidance, so your timeline may differ. Your nurse injector will reassess the muscle before recommending another session.
The BOTOX prescribing information carries a boxed warning: the toxin’s effect can spread beyond the injection site, causing symptoms such as generalized muscle weakness, double vision, drooping eyelids, trouble swallowing or speaking, or breathing problems. These can be life-threatening. Swallowing and breathing problems are a particular concern with injections in the neck area.
Seek urgent care if you notice trouble swallowing, breathing, or speaking, or new weakness after treatment. Tell your nurse injector before treatment about any neuromuscular condition, such as myasthenia gravis.
Your consultation should cover your medical history, the proposed unit count, the total cost, possible side effects, and alternatives.
“Barbie Botox” is a social media name for botulinum toxin injected into the trapezius. At many clinics, Barbie Botox and Traptox describe the same treatment. Neither is a standardized protocol, and some providers use the nickname for a broader contouring plan that includes other areas.
Ask which muscles will be treated, which product will be used, and how many units are included. The name doesn’t tell you the dose or the price. For more on the treatment itself, read what Traptox is and how it works.
At InjectCo, Botox is $7.77 per unit with the InjectCo membership ($24.99/month), or $12 per unit without it, so your total depends on the units used. For example, 60 units is $720, 80 units is $960, and 100 units is $1,200.
Published studies used about 30 to 50 units of Botox per side, or 60 to 100 total. There’s no labeled dose for cosmetic use, so your nurse injector sets the amount after an assessment.
Not for cosmetic shoulder slimming. InjectCo does not bill insurance. Botulinum toxin for a diagnosed condition like cervical dystonia follows a separate, physician-led pathway.
It’s temporary. In one study, muscle thickness was still reduced at 44 weeks after Botox; in another, the Botox effect was measurable at 60 days but no longer significant at one year.
Often, yes. Both names usually describe botulinum toxin in the trapezius, but neither is standardized, so ask what’s included.
Some people report less tension, but InjectCo offers Traptox as a cosmetic service and doesn’t promise pain relief. If pain is your main concern, see a physician first.
Trap Botox costs $7.77 per unit with the InjectCo membership ($24.99/month), or $12 per unit without it, at InjectCo, and published studies used about 30 to 50 units per shoulder. It’s cosmetic, off-label, and self-pay, and results are temporary, so plan for repeat visits.
An InjectCo nurse injector will assess your trapezius, confirm the unit count, and give you the total before you commit.
Know the total before booking treatment.
