What are muscle slimming injections?

These slimming injections can effectively weaken specific muscles to obtain a slimmer appearance. They usually give legs and shoulders an aesthetically pleasing and more ‘elegant’ look. On the other hand, muscle hypertrophy can make legs and shoulders appear ‘bulky’.

This treatment can also effectively weaken masseter muscles, stopping nighttime teeth grinding. Over time, the muscles will reduce in size, making the face look slimmer and heart-shaped. Teeth grinding happens at night and is usually involuntary (without conscious efforts). Furthermore, it is detrimental to the health of the teeth and, over time, can result in large square jaws that look obvious and unnatural.

This treatment can be combined with the following procedures:

– Body Sculpting and Contouring Treatment

– Dermamelan Intimate Peel

– Laser Hair Removal

– Laser Hair Bleaching

– Ultraformer 3 HIFU

The combination of treatments can be discussed at your consultation, followed by a bespoke treatment plan to help you achieve your desired results!


Before your treatment, avoid taking blood thinners.

Additionally, it is recommended that skin treatments such as:

HIFU, Fractional Microneedling RF, IPL, Chemical Peels, etc., be received before injections to prevent interference with the treatment’s efficacy.

However, don’t worry, our specialists will give you guidance and information during a thorough consultation before the treatment!


Remember to avoid massaging or sleeping on the treated area for up to 48 hours after the treatment.

Avoid alcohol as it increases the risk of bruising.

Furthermore, you may experience mild tenderness and bruising after your treatment. Please remember that this is a normal reaction to injections.

Additionally, our specialists may recommend adopting other habits to prolong the results of your treatment. Schedule a consultation session to learn more.

How do muscle slimming injections work?

The toxin muscle slimming treatment blocks the interaction between the muscles and the nerves. This prevents the muscle from contracting, reducing the size of bulky muscles and resulting in a more slender appearance.

Legs will appear thinner, and the neck-shoulder line will have a more swan-shaped appearance.

Who is it suitable for?

Exercise and lifestyle choices can cause certain muscles to bulk up, resulting in an undesirable appearance. Sometimes, genetics play a role, and some individuals naturally have thicker shoulder lines and lower legs.

This treatment aims to reduce the size of these muscles, resulting in a slimmer appearance. Additionally, it addresses teeth grinding, which, as a side effect, leads to a slimmer jaw muscle, giving the face a more contoured shape. Some individuals may have a genetic predisposition to large, square jaws. Several studies have suggested that East Asians may have genetically more hypertrophied masseter muscles. Large, square jaws, particularly in women, can give a more masculine impression.

While large calf and shoulder muscles can be hereditary, we recommend scheduling an in-depth consultation with one of our professionals to better assess your suitability.


  • Suitable for male and female
  • No downtime
  • Only need a few sessions to achieve optimal results
  • Involves little to no discomfort
  • With maintenance, results are long-lasting!

How long does the treatment take?

The treatment lasts approximately 30 minutes. Additionally, we book a follow-up appointment 2-3 weeks later to assess whether you need further treatments.

How long will the results last?

The treatment will generally continue to have effects for 3-6 months. After this period, the muscles will slowly regain strength and become more active again. With regards to shoulders and calf muscles, especially if the patient keeps exercising these specific muscles, they will retain shape and bulk up again. At this point, it is recommended to repeat treatments.

When will I see results?

The muscles typically feel ‘hard’ and ‘strong’ at baseline. After the injection, the muscles will soften in about 2 weeks. Then, a visible reduction in muscle size can be observed from 4 weeks and will peak around 6 weeks.
