Traptox, or trapezius Botox, typically costs $960 to $1,440 per session at InjectCo when 80 to 120 total Botox units are used. Members would pay $720 to $1,080 at the $9-per-unit rate. Your exact total depends on muscle size, symmetry, cosmetic goals, and the unit count recommended after assessment.
These prices are planning examples, not fixed treatment recommendations. Some patients may need fewer or more units based on their anatomy and treatment plan.

The price of Traptox depends primarily on the number of Botox units used. Because the trapezius is larger than most facial muscles, treating both shoulders generally requires more units than a smaller facial area.
Traptox at InjectCo involves injecting Botox into the trapezius muscles, which extend across the neck, shoulders, and upper back. The injections temporarily reduce activity in targeted parts of the muscle.
For cosmetic treatment, this may gradually soften the appearance of prominent trapezius muscles and create a more tapered shoulder line. Some patients also report less muscle tension, but this is not a guaranteed result.
Using Botox specifically for cosmetic shoulder slimming is off-label. Your provider should explain what that means, along with the potential risks and alternatives, before treatment.
As of August 2026, InjectCo charges $12 per Botox unit at the standard rate and $9 per unit for members. Most planning examples use 80 to 120 total units across both shoulders.
Your provider will determine how many Botox units you need after assessing your muscle size, strength, symmetry, and cosmetic goals.
Published clinic prices across the wider market currently range from about $500 per session to $2,500 per session. However, those broad ranges do not tell you what you will pay at InjectCo.
| Planning Example | Total Botox Units | Standard Price at $12 Per Unit | Member Price at $9 Per Unit | Typical Sessions Per Year |
|---|---|---|---|---|
| Lighter build or desk-related tension | 80 | $960 | $720 | Two to three |
| Moderate trapezius development | 100 | $1,200 | $900 | Two to three |
| Larger or highly developed trapezius muscles | 120 | $1,440 | $1,080 | Two to three |
These figures are planning examples, not treatment packages. Your recommended unit count may fall outside these examples.
The table applies only to Botox pricing. Units from Dysport, Xeomin, and other botulinum toxin products are not directly interchangeable with Botox units.
Get Your Own Unit Count and Total in Writing
A nurse injector will assess your trapezius, confirm the unit count, and give you the exact self-pay total before anything is booked.
Several factors can change your final trapezius Botox cost:
Ask for a detailed estimate that states the product, total units, per-unit price, and expected treatment schedule.

For cosmetic shoulder slimming, Traptox is not billed to insurance. InjectCo does not bill insurance, and Traptox appointments at InjectCo are self-pay cosmetic services.
Botulinum toxin may also be used through a medical pathway for certain diagnosed conditions. For example, the official BOTOX prescribing information lists cervical dystonia as an approved medical indication in adults.
That medical use is separate from cosmetic Traptox. It requires evaluation, diagnosis, and treatment planning by an appropriate physician. A cosmetic med spa appointment cannot substitute for that process.
InjectCo cannot diagnose cervical dystonia, chronic migraine, or another medical condition to help someone obtain coverage. It also cannot arrange insurance reimbursement for cosmetic trapezius Botox.
If neck or shoulder pain is your main reason for considering treatment, speak with a physician first. Your symptoms may need medical evaluation, physical therapy, or another form of care before you consider a cosmetic service.
Many patients schedule two to three Traptox appointments per year because the effects are temporary. Your actual schedule may differ based on your response and cosmetic goals.
| Units Per Session | Standard Annual Cost for Two to Three Sessions | Member Annual Cost for Two to Three Sessions |
|---|---|---|
| 80 | $1,920 to $2,880 | $1,440 to $2,160 |
| 100 | $2,400 to $3,600 | $1,800 to $2,700 |
| 120 | $2,880 to $4,320 | $2,160 to $3,240 |
Review InjectCo’s transparent pricing when planning your budget. Every estimate should begin with your unit count rather than a broad national range.
If tension or pain is your main concern, massage or physical therapy may cost less per visit. These options serve a different purpose and may be more appropriate after medical evaluation.

Meet with a nurse injector to review your anatomy, cosmetic goals, expected unit count, and complete treatment cost.
Traptox is temporary. Its effects commonly last three to six months before muscle activity gradually returns.
Longevity varies based on the unit count, muscle activity, metabolism, and individual response. Some patients schedule two appointments per year, while others may prefer three.
Individual results and treatment intervals vary.
You will not see the full effect immediately. The trapezius muscles may begin relaxing within five to seven days, with the initial effect becoming easier to assess around two weeks.
Visible changes to the shoulder contour may continue developing as the treated muscles respond. Some patients also report less tension in the upper back or neck, but InjectCo does not present pain relief as an expected cosmetic outcome.
The effects are not permanent. Maintaining a cosmetic result requires reassessment and additional treatment when appropriate.

Traptox uses the same Botox product used for many facial treatments, but the treatment area, unit requirements, goals, and cost differ.
“Barbie Botox” is a popular name for botulinum toxin injections placed in the trapezius muscles. In many clinics, Barbie Botox and Traptox describe the same basic treatment.
However, Barbie Botox is not a standardized medical protocol. Some providers may use the term for a broader contouring plan that includes other treatment areas.
Ask which muscles will be treated, which product will be used, and how many units are included. Do not assume the nickname means fewer units or a lower price.
The main difference is the size of the muscle being treated. A small cosmetic facial area may use about 10 to 30 Botox units, while trapezius treatment may use 80 to 120 total units across both shoulders.
Because Traptox generally requires more units, its total cost is often higher than Botox for one facial area. Unit recommendations still depend on individual anatomy and should not be treated as fixed amounts.
Traptox may be worth considering if shoulder slimming is an important cosmetic goal and the ongoing cost fits your budget. The decision should account for the first treatment and possible maintenance appointments.
Before deciding, ask yourself:
During your consultation, one of our nurse injectors will review your medical history, trapezius anatomy, shoulder symmetry, and cosmetic goals.
You should receive a clear explanation of:
The consultation may also determine that Traptox is not the right option for your anatomy or concern. You should have enough information to make the decision without rushing.

Review your goals, expected Botox units, self-pay cost, and treatment schedule with an experienced InjectCo nurse injector.
Many patients report less neck or shoulder tension after Traptox. However, cosmetic Traptox is not a treatment for diagnosed pain conditions. If pain is your primary concern, speak with a physician before booking.
Traptox temporarily reduces activity in targeted parts of the trapezius muscle. Many patients report feeling less tension, but the response varies. InjectCo does not guarantee tension or pain relief from cosmetic treatment.
Treatment often uses 40 to 60 Botox units per shoulder, or 80 to 120 units total. Your anatomy, muscle strength, symmetry, and cosmetic goal determine the final recommendation.
InjectCo offers Traptox as a cosmetic service for shoulder and neckline contouring. Some patients report less tension, but this is not guaranteed and should not replace medical evaluation for pain.
InjectCo cannot predict or promise pain relief from cosmetic Traptox. Patients who report less tension may notice it changing as Botox wears off, commonly within three to six months.
The trapezius muscles are larger than the small muscles commonly treated for facial lines. As a result, trapezius treatment generally requires more Botox units and has a higher total cost.
InjectCo does not bill insurance for Traptox. Cosmetic trapezius Botox at InjectCo is a self-pay service. Medical botulinum toxin treatment for a diagnosed condition follows a separate physician-led pathway.
Many Traptox plans use 80 to 120 total Botox units across both shoulders. Your provider must assess your anatomy, muscle activity, symmetry, and cosmetic goals before recommending an amount.
Traptox may be worth considering if you want a slimmer shoulder contour and understand that the results are temporary. However, treatment should only move forward after a qualified provider evaluates your anatomy, muscle activity, and overall suitability.
An InjectCo nurse injector can explain the expected results, potential risks, and maintenance involved so you can make an informed decision without pressure.

Meet with an InjectCo nurse injector for a personalized assessment based on your anatomy and cosmetic goals.
