Botox or botulinum toxin is best known for its wrinkle removal effects but did you know that it can also be used for body contouring? Besides slimming the jaw and calf muscles, shoulder botox injections or trapezius muscle botox is used to slim and sharpen bulky shoulder muscles. The result of trapezius botox or shoulder botox injections is reduced neck and shoulder tension and a slimmer and more feminine silhouette for females.

 

The trapezius muscle is a large muscle that extends from the back of the head and neck to the shoulders. When the trapezius muscle is enlarged or hypertrophic, the shoulders look bulky and more masculine. Hypertrophic trapezius muscles also have the effect of making the neck look shorter and face wider.

 

One way to treat hypertrophic trapezius is with Botox/ botulinum toxin injections. Trapezius botox injections help to correct and contour big shoulder and collarbone muscles for a slimmer silhouette. Trapezius botox or shoulder botox injections started getting popular 4-5 years ago in South Korea and China. In Singapore, I’m noticing an increasing interest in botox injections for slim arms/ shoulders. This review will examine contouring of the shoulder and collarbone muscles with trapezius botox injections and safety issues surrounding it.

What does trapezius botox treat?

The trapezius muscle is a large flat muscle that extends from the back of the head and neck to the shoulders sideways. The function of the trapezius muscle is to pull the shoulders upwards (shrugging) and backwards and neck extension and turning.

 

Enlarged trapezius muscles can occur in people who have overactive trapezius muscles. Overactive trapezius muscles can become hypertrophic. The enlarged trapezius muscles makes the shoulder and muscles above the collarbone look bigger. The neck also looks shorter and the face looks wider in comparison. The overall appearance is more masculine and stockier. For females, this masculine appearance can be obvious, especially when shoulder-baring outfits are worn.

 

Overactive trapezius muscles can occur in non-body builders. In a condition known as upper crossed syndrome, poor posture strains the trapezius muscle, causing pain, stiffness and aches in the upper back and neck.

 

Upper cross syndrome is seen in people who bend their backs and necks forward, similar to a hunched posture or slouching. This posture is also commonly seen in people who hunch their backs and neck while working at their desks. The constant overactivity of the muscles causes the trapezius to become overdeveloped. So while you’re reading this blogpost- remember to stretch!

 

Trapezius botox injections are one way of treating overactive or overdeveloped or hypertrophic trapezius muscles. Botulinum toxin is injected into the trigger points of the muscles to relax the trapezius muscles. The trapezius muscle slims down over weeks and the shoulders and collarbones look slimmer and more feminine.

How does trapezius botox work?

Botox or botulinum toxin is a neurotoxin that relaxes muscles. Botulinum toxins acts at neuromuscular junctions to relax muscle. When used in the face, botox relaxes the facial muscles to remove wrinkles. When injected into the masseter muscles, botox relaxes the jaw muscles to reduce teeth grinding and slim down the face shape.

 

Similarly, when botulinum toxin is injected safely into the trapezius muscles, the muscles can be relaxed without affecting normal movement of the arm, shoulder joint, back and neck. As the overactivity of the trapezius muscle is curbed, the hypertrophic trapezius muscles lose their bulk and size. This is akin to a bodybuilder who stops working out and loses his muscle mass over weeks.

 

Over a few weeks, the bulky hypertrophic muscles slim down for a slimmer and more elegant neckline. The results of trapezius botox lasts for 4-6 months.

   

How is trapezius botox for shoulder contouring done in Singapore?

 

Botulinum toxin is injected into the upper shoulder (trapezius muscle) directly. These injections are placed at the points of the nerve that supplies the trapezius muscle. 4-5 injections points are required on average. The entire treatment will take approximately 5-10 minutes.

 

Are trapezius botox injections safe? What are the side effects of shoulder contouring with botulinum toxin?

 

Botulinum toxin has been used for medical treatments for decades in various specialities including neurology and dermatology. The safety issues surrounding Botulinum toxin have been discussed in this blogpost Is Botox Deadly?

 

The use of botulinum toxin for shoulder contouring is an off-label indication. There are a few studies on trapezius botox injections for pain and contouring. These studies show that trapezius botox injections are generally safe and side effects that occur are temporary.

The dosages of Botulinum toxin used for trapezius muscle injections is relatively small. With any injections, there may be muscle aches and soreness related to the injections rather than botulinum toxin. Some of the specific risks related to botox trapezius injections are neck and shoulder weaknesses and imbalances in sizes of both shoulders.

   

 

What are the alternatives to trapezius botox injections for shoulder contouring?

 

The alternative to trapezius botox injections to slim down large shoulder muscles is surgery. (e.g. skeletonisation and defatting of the large muscles and tissues). The advantage of surgery is that the results are longer lasting than trapezius botox. One disadvantage of surgery for shoulder contouring is that the shoulders look hollowed out and the neck- shoulder contours look unnatural.

 

How long do the results of trapezius botox for shoulder contouring last?

The results of botulinum toxin injections last 4-6 months.

How soon can the results of trapezius botox for shoulder contouring be seen?

It takes approximately 4-6 weeks for the shoulder muscles to slim down after trapezius botox injections.

 

How many units of Botox are required for trapezius botox injections for shoulder contouring?

40-50 units of Botox are used for trapezius botox for shoulder contouring on each side.

 

Am I suitable for shoulder conoturing? What are the pitfalls or limitations of trapezius botox injections?

Trapezius botox injections for shoulder contouring are effective for overactive or hypertrophic shoulder muscles. If your shoulders are enlarged due to other reasons, trapezius botox injections may not be effective in slimming down the shoulders.

 

If you have previous injuries or surgeries to your shoulder, arms, necks- please inform your doctor. You may not be suitable for botox injections to the shoulders.

Trapezius botox injections is also one of the treatments for aches and pains due to overactive trapezius muscles.
