Jawline slimming and teeth grinding treatments use therapeutic injectable treatment, commonly known as Botox, to reduce excessive activity in the masseter muscles. These muscles sit at the angle of the jaw and play a key role in chewing and clenching. When overactive, they can contribute to jaw tension, teeth grinding and a wider or heavier lower face.
At JB Aesthetics, jawline slimming and bruxism treatments are delivered by qualified doctors using a precise, anatomy-led approach. Treatment is tailored to address both functional concerns and facial balance, ensuring natural proportions are maintained.

What Is Jawline Slimming?
Jawline slimming focuses on reducing the bulk of the masseter muscles using therapeutic injectable treatment. Repetitive clenching or grinding can cause these muscles to enlarge over time, leading to a wider or more square appearance of the lower face.
By gently reducing excessive muscle activity, the jawline becomes softer and more contoured. Normal chewing function is preserved, and changes develop gradually for a balanced and natural-looking outcome.

Reduces clenching and grinding associated with bruxism.

Refines Lower Face Contour

Jawline Slimming for Men & Women
This treatment is suitable for both men and women, although treatment goals may differ.
For women, treatment often focuses on reducing jaw bulk while maintaining a smooth and balanced contour.
For men, treatment may prioritise relief from clenching and grinding while preserving a strong and masculine jawline. Dosage and placement are carefully adjusted to suit individual anatomy.
