What is Facial Slimming Treatment? Masseter Injections Info

In the world of aesthetic enhancements, facial slimming treatments have gained popularity for their ability to create a more refined and contoured facial appearance. But what is Facial Slimming? One such treatment that has been increasingly sought after is masseter injections.

In this article we dive into the details of this innovative procedure, its benefits, costs, and considerations.

What is Facial Slimming Treatment?

Facial slimming treatment is a non-surgical procedure aimed at reducing the width of the lower face by targeting the masseter muscles using anti-wrinkle injections such as Botox as a muscle relaxant of the facial muscles, resulting in a more V-shaped or oval facial contour.

The masseter muscles are responsible for chewing and can become enlarged due to genetics, teeth grinding, or excessive chewing.

What Injectable is Used to Slim the Masseter Muscles?

The primary injectable used for masseter muscle slimming is Botulinum toxin type A, commonly known as Botox.

Botox is only one brand of anti-wrinkle injectable, but many others exist in the market today, talk to your cosmetic injector to see what brands they have on offer.

How does Facial Slimming work?

Botox works by temporarily relaxing the masseters, leading to a reduction in muscle size and a softer jawline.

This is completely different to other injectable products like dermal fillers, which are used to shape the area using volume enhancing hyaluronic acid filler.

Benefits of Facial Slimming

Facial slimming offers several aesthetic benefits, including:

  • Enhanced facial contours and a more feminine jawline (feminine face shape)
  • Reduction in the appearance of a square jaw
  • Relief from jaw tension and teeth grinding (bruxism)
  • Improved facial symmetry

How Much Does Facial Slimming Cost?

The cost of facial slimming treatments varies depending on factors such as the practitioner's experience, the geographical location, and the number of units of Botox required.

On average, the cost can range from $349 to $900 per session.

Men generally need more units of product than women due to the size of the masseter (jaw muscles), so if you're a man you should take this into consideration.

Choosing the Number of Units for Face Slimming Injections

The number of units required for facial slimming injections depends on the individual's muscle mass and desired results. Typically, 20 to 50 units of Botox are injected into each masseter muscle.

A skilled practitioner will assess your facial structure and recommend the appropriate dosage.

If your practitioner uses an alternative brand to Botox, you may require more units, so keep this in mind if you see a cheap "per unit" price.

What Happens During the Masseter Treatment Itself?

The masseter treatment is a quick and relatively painless procedure. After cleaning the injection site, the practitioner will administer small amounts of Botox into the masseters using a fine needle.

The entire process takes about 15 to 30 minutes, and there is no downtime required.

Who is Unsuitable for Treatment of Masseters?

Individuals with neuromuscular disorders, active skin infections, or allergies to Botox ingredients may not be suitable candidates for masseter treatment.

Pregnant or breastfeeding women should also avoid this procedure.

Side Effects and Risks of Face Slimming Treatments

While generally safe, facial slimming treatments can have potential side effects, including:

  • Bruising and swelling at the injection site
  • Temporary weakness in the masseters
  • Asymmetry or uneven results
  • Rarely, spread of the toxin to nearby muscles, causing unintended effects


In conclusion, face slimming treatment (jawline slimming injections) through masseter injections offers a non-invasive solution for achieving a more refined and contoured facial appearance.

By understanding the procedure, benefits, and considerations, individuals can make informed decisions about this popular aesthetic enhancement.

It's essential to choose a qualified and experienced practitioner to minimize risks and achieve optimal results with your muscle relaxing injections.
