Masseter Botox

Jaw Slimming & Teeth Grinding Treatment in London

Masseter Botox relaxes the jaw muscle to help slim the lower face and relieve tension caused by teeth grinding or jaw clenching. By reducing the strength of the masseter muscle, the treatment can soften a square jawline, relieve discomfort associated with TMJ, and create a more balanced facial contour.

Over time, the muscle gradually becomes less bulky, helping to achieve a slimmer and more refined jawline while also reducing symptoms such as jaw tension, headaches, and grinding.

Please note that results develop gradually over 4–6 weeks as the muscle relaxes and reduces in size.

What is Masseter Botox?

Masseter Botox is a non-surgical treatment that relaxes the masseter muscle, the powerful chewing muscle located at the angle of the jaw. When this muscle becomes enlarged due to clenching or grinding, it can create a wider, square jawline and contribute to symptoms of TMJ discomfort, headaches, and jaw tension.

By carefully injecting anti-wrinkle treatment into the masseter muscle, the muscle gradually relaxes and reduces in size over time. This results in a slimmer jawline, softer facial contours, and relief from jaw tension or teeth grinding.

At M&K Aesthetics in London, masseter Botox is performed by experienced medical practitioners using advanced injection techniques to ensure natural-looking results.

Benefits of Masseter Botox

Masseter Botox can provide both cosmetic and therapeutic benefits, including:

  • Slimming and contouring the jawline
  • Softening a square or bulky lower face
  • Reducing teeth grinding (bruxism)
  • Relieving jaw tension and TMJ discomfort
  • Helping reduce tension headaches caused by clenching
  • Creating a more balanced facial profile

Many patients choose this treatment to achieve a more V-shaped facial contour while also improving jaw comfort.

Who is a Good Candidate?

Masseter Botox may be suitable if you:

  • Have a square or wide jawline caused by strong jaw muscles
  • Experience jaw clenching or teeth grinding
  • Suffer from TMJ discomfort or jaw tension
  • Want a non-surgical jaw slimming treatment

A consultation at M&K Aesthetics London will determine whether this treatment is suitable for you.

How the Treatment Works

The treatment involves a series of small injections placed directly into the masseter muscle on both sides of the jaw.

The procedure is quick and minimally uncomfortable. Most patients describe the injections as a small pinch.

Once the muscle relaxes, it gradually reduces in size, resulting in a slimmer and more refined jawline over time.

Results and Longevity

Initial effects appear within 1–2 weeks, with full slimming and muscle relaxation developing gradually over 4–6 weeks.
Results typically last 4–5 months depending on muscle strength.

What to Expect After Treatment

  • Mild tenderness at injection points may occur
  • Normal activities can usually be resumed immediately
  • Full jaw slimming results develop gradually over 4–6 weeks

The experience I had was nothing short of fabulous; the welcome from Marie and Elanda was perfect, they were great, beautiful, and super prepared to give you the best advice on how to resolve or mitigate the small aesthetic issues you want to improve! I trusted them to improve my situation with dark circles, and I must say that the result speaks for itself! Another magnificent thing was their availability to accommodate my schedule! In summary, a 5-star experience out of 5!! I highly recommend it!

I recently started my Morpheus& treatment plan here, and my beautician, Ellie, has been absolutely wonderful. She is incredibly patient and took the time to answer all my questions. The procedure itself was smoothly guided, and I felt truly looked after. I also received excellent skincare advice, which I found very helpful. I would definitely recommend M&K Aesthetics!

Marie and her team are not only welcoming and accommodating to everyone's needs but extremely professional and knowledgeable. I see elanda on a regular basis for skin boosters, Botox and filler. She is an incredibly qualified nurse who makes you feel at ease and keeps you informed throughout the whole process. Of course the best part is how easy it is to get along with her! I cannot recommend M&K enough! Thank you for always putting the client first!

I visited M&K Aesthetics this January and currently completing my IPL course with Lumecca. Marie is an excellent practitioner and my results are incredible so far. Wouldn't go anywhere else for my treatments.
