What are jaw slimming injections?
Jaw slimming injections use a prescription muscle-relaxing treatment to reduce the activity of the masseter muscles on each side of the jaw. When these muscles are overactive or hypertrophic — often from teeth grinding, jaw clenching, or simply genetics — they can give the face a more squared, heavy appearance. By gently reducing masseter activity, the face naturally adopts a softer, more tapered contour over several weeks.
Benefits
Non-surgical — no anaesthesia, no incisions, no recovery period. A clinic appointment with immediate return to daily activities.
Minimal downtime — patients typically resume their normal routine the same day.
Natural-looking results — the aim is subtle refinement, not a dramatic change. Results develop gradually over 4–6 weeks as the muscle softens.
The procedure
The treatment takes approximately 15–30 minutes from start to finish. Following a consultation to assess your anatomy, muscle activity and desired outcome, small, precise amounts of the muscle-relaxing treatment are administered into the masseter muscles using a very fine needle. Most patients find the procedure comfortable and well-tolerated.
Results typically become visible from 4–6 weeks and last 4–6 months, with the muscle gradually returning to its previous state if treatment is not maintained.
Is it right for me?
Jaw slimming treatment is suitable for patients who experience a wider or more squared lower face due to masseter hypertrophy, teeth grinding (bruxism), or jaw clenching. It can also provide relief from associated jaw tension and discomfort. A full consultation is required before treatment.
