What the treatment can do

Short neck? Bulky shoulders? Muscular traps? Overdeveloped trapezius muscles can masculinise your neck, creating a ‘hulking’ effect. It can also have an ageing effect, by making you look hunched, and create tension and discomfort.

Whether through genetics or weight training, muscle slimming injections can safely slim down large trapezius muscles. This gives your neck and shoulders a contoured, elegant appearance.

During your consultation, our experienced medical professionals can guide you on your options. We will work with you to design a personalised treatment to achieve a slimmer neck and shoulders.


Experience the benefits of trapezius neck slimming injections done by experts at Cosmetic Connection:

  • Reduces bulky, overdeveloped trapezius muscles
  • Gives your neck a slimmer, longer appearance
  • Reduces neck and shoulder tension by relaxing the trapezius muscles
  • Can improve headaches caused by tension in your trapezius muscles
  • Non-invasive and no downtime treatment


Large shoulders and a short neck caused by enlarged trapezius muscles can be quickly and conveniently treated with trapezius slimming injections.


To ensure your trapezius slimming treatment goes to plan, follow our preparation guidelines:

  • Avoid consuming excessive alcohol within 24 hours of your appointment
  • Refrain from intense exercise immediately before your appointment
  • Be conscious of the clothing your wear, as we will need to assess the top of your shoulders and neck


After your trapezius neck slimming treatment, proper aftercare is crucial for optimal healing and results:

  • Mild tenderness is to be expected
  • A slight reduction in should/neck strength may be noticed
  • The trapezius muscle will gradually slim down over a 4-6 week period
  • Avoid excessive alcohol and intense exercise until the following day
  • Refrain from applying pressure to the treated areas for 4 hours
  • Gently apply a wrapped ice pack to the injection sites to minimise swelling and bruising


Experience slimmer neck and shoulder contours just 6 weeks after your treatment. Your result will emerge gradually as your trapezius muscles reduce in size.

Your result depends on the size and strength of your trapezius muscles, and the amount of muscle slimming product injected. We can achieve more pronounced results with additional slimming treatments when appropriate.

Expect to maintain your new, slim neck every 6-9 months. Regular maintenance can make your results last even longer.

    There are a number of ways to reduce large trapezius muscles.

    Avoiding activities that place strain on your trapezius muscles can reduce their strength causing them to reduce in size.

    We can use trapezius neck slimming injections relax the muscles, reducing their size.

    You can reduce your big trapezius muscles by:

    • Reducing strenuous activity that requires the use of the trapezius muscles.
    • Having trapezius neck slimming injections.

    Strenuous activities cause your trapezius muscles to enlarge.

    Some people are prone to developing large trapezius muscles with normal levels of physical activity.

    Women with large breasts may also have overdeveloped trapezius muscles that provide support to their shoulders and upper back.

    An overdeveloped trapezius muscle can make your neck look wider and more muscular.

    A large, bulky trapezius muscle can make your neck look shorter. This is cause it widens your lower neck and elevates the top of your shoulders.

    Trapezius neck slimming injections involve the precise placement of muscle relaxing product into the trapezius muscles.

    Generally, we place 5 injections on each size with tiny needles.

    When performed with fine needles and a gentle technique, trapezius neck slimming injections have minimal discomfort.

    At a minimum, most people need 50 units of muscle relaxant per side to slim their trapezius.

    We can use fewer units when treating trapezius muscle tension.

    You’ll notice a reduction in your trapezius strength 2 weeks after your injections. The slimming effect gradually occurs over 6 weeks from the day of your treatment.

    Most people repeat their trapezius neck slimming injections every 6-9 months.

    To prepare for trapezius neck slimming injections you should avoid alcohol and intense exercise before your appointment.

    After trapezius neck slimming injections, avoid intense exercise and alcohol for 1-2 days. You should also avoid applying any pressure to the injection sites for 6 hours to avoid dispersing the product.

    When performed by an appropriately qualified cosmetic practitioner trapezius neck slimming injections are a low risk treatment.

    The most common side effects are temporary redness and tenderness at the injection sites.

    Rare risks include neck and shoulder weakness. This is usually mild and will resolve on its own as the treatment wears off.
