Trapezius Injections
Slimmer shoulders, an elongated neck, and lasting relief from tension - in one targeted treatment.
Also known as: Trap Tox · Barbie Botox · Shoulder Slimming Injections
What are Trapezius Injections?
—— WHAT IT IS
The trapezius is a large muscle that runs from the base of the skull, across the shoulders, and down the mid-back. When this muscle becomes overactive, enlarged, or chronically tense - whether from poor posture, stress, desk work, or physical activity - it can shorten the visual line of the neck, create a heavier shoulder silhouette, and cause persistent pain, stiffness, and tension headaches.
Trapezius injections use a purified neuromodulator to gently relax the overactive fibres of this muscle, offering a dual benefit: a more refined, elegant shoulder and neck contour, alongside meaningful relief from chronic tension and discomfort. It is a treatment that works quietly and precisely - with results that speak for themselves.
A simple, gentle process
—— HOW IT WORKS
The neuromodulator is injected into specific areas of the trapezius muscle using a fine needle. By temporarily blocking the nerve signals that cause the muscle to contract, the treated fibres gradually relax and lengthen. The result is a reduction in both muscle bulk and tension — creating a longer, softer neck profile and relieving the tightness that causes day-to-day discomfort.
The treatment is precise and localised, targeting only the areas of concern while leaving surrounding muscles entirely unaffected. Effects begin within a few days and reach their peak at around two weeks.
Neuromodulator injections have been used safely for many years.

What to Expect
During:
A consultation with Dr Mildred is the first step, allowing her to assess the trapezius muscles, discuss your goals - whether aesthetic, therapeutic, or both - and confirm the treatment is appropriate for you. The injections are then administered using a fine needle into the identified areas of the trapezius. The procedure takes under 30 minutes, and most patients find it very comfortable throughout.
After:
You can return to normal daily activities immediately - there is no downtime. The neuromodulator begins to take effect within a few days, with the muscle gradually relaxing and softening over the following two weeks. Some mild tenderness at the injection sites is normal and settles quickly. Dr Mildred will provide aftercare guidance and discuss timing for any follow-up treatment.
Who is this for?
—— IS THIS RIGHT FOR YOU?
Trapezius injections suit a wide range of patients. If you spend long hours at a desk, carry tension in your neck and shoulders, or suffer from recurring tension headaches, this treatment may offer the lasting relief that massage, stretching, and other approaches haven't provided.
If you're looking to refine your upper body silhouette - creating a longer neck, softer shoulder line, and more elegant overall contour - the aesthetic benefits of this treatment are equally well established.
Many patients come for one reason and discover both benefits. During your consultation, Dr Mildred will discuss your priorities and tailor the approach to your individual goals.
Safety & Considerations
Trapezius injections use a well-established neuromodulator with a strong safety profile across both aesthetic and therapeutic applications. All treatments at Thrive are carried out by Dr Mildred, a qualified Doctor with specialist training in aesthetics. A full consultation is completed before any treatment to confirm it is appropriate for you.
Please note: treatment duration, discomfort levels, and recovery times can vary from person to person. While we provide general guidance based on clinical experience, factors such as individual pain tolerance, skin sensitivity, and the specifics of your treatment may influence your experience. A personalised consultation ensures your treatment is precisely tailored to your needs and goals.
