Masseter Muscle Reduction
Masseter muscle reduction is a highly effective procedure performed sought both for aesthetic purposes – creating a softer, more proportionate facial contour – and therapeutic benefits – alleviating jaw tension, teeth grinding (bruxism), headaches and migraines.
It involves injecting neurotoxin into the masseter muscles, temporarily relaxing them to reduce overactivity.
How It Works
The injection of precise amounts of neurotoxin into the masseter muscles temporarily reduces muscle activity. This relaxes the muscles responsible for chewing and jaw clenching, providing relief from muscular pain, headaches, or jaw tension associated with overactive masseter muscles.
As the muscle activity decreases, the masseter muscles gradually reduce in size, creating a slimmer, more defined jawline. The aesthetic effect develops over 4–8 weeks, though sometimes repeated sessions may be needed if the muscles are particularly bulky to begin with.

FAQs
Am I suitable for masseter muscle reduction?
You may be an ideal candidate if you are seeking jawline slimming, facial balance, or relief from related symptoms such as teeth grinding, jaw tension, or headaches/migraines. Dr Shabri assesses each patient’s anatomy and aesthetic goals to create a tailored treatment plan.
Will this treatment affect my ability to chew or smile?
No. The treatment reduces muscle overactivity but does not eliminate normal function. You’ll still be able to eat and smile normally, but with less tension and grinding.
Is masseter muscle reduction safe?
Yes. When performed by Dr Shabri, this procedure is very safe. Established protocols and a thorough consultation ensure suitability and minimise risk.
Is the treatment painful?
The injections involve minimal discomfort, similar to other neurotoxin treatments. Most patients tolerate the procedure very well without anaesthetic.
How often will I need treatment?
Most patients achieve their desired results with one treatment session. However, if the masseter muscles are particularly bulky or overdeveloped, additional sessions may be recommended for optimal slimming.
Are there any side effects?
Mild tenderness or bruising at injection sites is common and usually resolves quickly. Rarely, temporary asymmetry of the smile may occur, which is discussed in detail during consultation.
