The approach

A softer, more refined lower face

Muscle-relaxing injections are placed into the masseter — the large chewing muscle at the angle of the jaw. Over a few weeks the muscle relaxes and gradually reduces in size, softening a square or heavy jawline and creating a slimmer, more balanced lower face.

The same treatment can ease teeth grinding (bruxism), jaw clenching and the tension and headaches that come with them. Placement is precise and conservative, tailored to your anatomy and goals.

Slimming develops gradually over 2–6 weeks and commonly lasts around 4–6 months, varying between individuals.

Is there downtime?

Downtime is generally minimal. Any specific aftercare will be explained at your appointment.
