What Is Masseter/Jawline Slimming ?

Our clinic offers Masseter/Jawline Slimming facial aesthetic treatment to help you achieve a more defined and balanced jawline.

This non-surgical procedure involves injecting a neuromodulator into the masseter muscles, reducing their size and relaxing their activity.

By slimming the masseter muscles, we can enhance the contours of your jawline, creating a more aesthetically pleasing facial profile. The benefits of Masseter/Jawline Slimming treatment extend beyond cosmetic improvements.

This treatment can alleviate symptoms associated with jaw clenching or teeth grinding, providing relief from temporomandibular joint (TMJ) disorders. Additionally, it can enhance facial symmetry, improve facial proportions, and boost self-confidence.

Meet The Aesthetics Team


I have now visited Twoth on three different occasion... The first time was to take my son (8 years old) to see Dr Counihan for a braces consultation and my son absolutely loved the entire experience from start to finish. In fact, he was so excited and relaxed about it all he wanted to get started immediately.

The second time around, I went to see Dr Counihan myself for a second opinion and found the experience just as good as my son did

Before I found Dr Neil Counihan I had a long history of dental trauma and sadly I repeatedly was subjected to very poor dentistry. I was scared to let anybody near my mouth and teeth. I had lost hope!

Dr Counihan made me the promise, with the right care I can keep my mouth healthy and definitely keep my teeth for the rest of my life.

And most importantly he made me feel safe and listened to
