Facial Slimming explained

What is facial slimming?

The masseter muscle is a strong muscle that contracts your jaw when chewing. It runs from your cheekbone down to your jawline, and in some people, it seems to grow more prominent than in others.

Facial slimming is an injectable treatment where botulinum toxin is injected into the masseter muscle, preventing it from contracting with full force. [1]

Is this treatment safe?

micro syringes

Little insulin microneedles to administer the treatment very safely. Such small syringes make it very safe and usually essentially pain-free. As shown in the picture adjacent, these microneedles are the same as what diabetic patients use multiple times per day, often making them painless.

How long will it last?

Just like any treatments using botulinum toxin, results vary but expect at least 3-4 months of duration before its action wanes. Many myths are circulating that factors such as heavy exercise or even diet may affect the treatment duration. This isn’t something that we have seen in our clinics to date.

Are there any other uses?


There are many other uses for botulinum toxin in the domain of muscle relaxing.  This treatment can be used for migraines as well a condition called, “Bruxism” [2].  Teeth grinding during sleep is a common medical condition that also responds well to this treatment as well as other sleep disorders. [3]

Facial slimming is a simple yet effective treatment to improve the appearance of your face.
