Masseteric Hypertrophy

Jawline slimming & facial balance

The masseter muscles are the powerful muscles located at the sides of the jaw and are responsible for chewing and jaw movement.

In some people, these muscles can become enlarged or overactive - known as Masseteric Hypertrophy - which may contribute to a wider or more square-shaped jawline.

How does it work?

The Masseter muscles play an important role in chewing, jaw movement and clenching.

Over time, repeated muscle activity from habits such as jaw clenching or teeth grinding (bruxism) can cause these muscles to become stronger and more prominent.

Unlike treatments that focus on softening lines and wrinkles, masseter treatment targets an overactive facial muscle.

Carefully placed anti-wrinkle injections help relax excessive muscle activity, gradually reducing the strength and prominence of the masseter muscles.

For suitable patients, this can help soften the appearance of a wider jawline and create a more balanced facial shape.

Treatment may also help those who experience jaw tension associated with clenching or grinding.

Every treatment plan is personalised based on your facial structure, muscle activity and desired outcome.

The aim is to enhance facial balance while keeping your results natural.
