Description
Jaw slimming treatment is a non-surgical procedure designed to contour the jawline and create a slimmer, more defined lower face. The treatment targets the masseter muscles, which can become enlarged due to habits such as teeth grinding (bruxism), jaw clenching, or heavy chewing.
When these muscles become overactive, they may create a square or bulky jawline and can also contribute to jaw tension, headaches, or TMJ discomfort.
At AesthetiCare Clinic in Moorgate, Central London, jaw slimming treatments are performed in a doctor-led clinical setting, ensuring treatment is tailored to each patient’s facial anatomy and functional concerns.
This treatment can improve both facial aesthetics and jaw tension symptoms, creating a more balanced and comfortable lower face.
Jaw slimming treatment may be suitable for patients who:
• Feel their jawline appears wide or square
• Experience jaw clenching or teeth grinding (bruxism)
• Have symptoms of TMJ discomfort or jaw tension
• Would like a more tapered or V-shaped lower face
How Jaw Slimming Treatment Works
The procedure involves precise injections into the masseter muscles on both sides of the jaw.
These injections temporarily relax the muscle, reducing its strength and activity.
Over time:
• The masseter muscle gradually reduces in size
• The jawline becomes slimmer and more contoured
• Facial balance improves
• Jaw tension and clenching may decrease
Because the treatment specifically targets the masseter muscle, normal facial expressions and chewing function remain unaffected.
The slimming effect develops gradually as the muscle becomes less active, creating a natural and subtle transformation of the lower face.
