Masseter Hypertrophy
Masseter Botox & Jawline Slimming
Targeted relief. Refined aesthetics. Trusted care on Harley Street.
At Youth Encore, we offer advanced Botox treatments for masseter hypertrophy — a condition where the jaw muscles become enlarged due to tension, grinding or overuse. This can cause both discomfort and an overly square jawline. Our masseter Botox treatment provides a safe, non-surgical solution to relieve symptoms of bruxism, reshape the lower face, and enhance jawline definition.
We work regularly with clients from Bond Street, Marylebone, and across London. Whether you’re seeking relief from TMJ discomfort or simply looking to refine your facial shape, our experienced team on Harley Street is here to help.
What Is Masseter Botox?
The masseter is one of the strongest muscles in your face — essential for chewing, but often overworked. In people who suffer from teeth grinding (bruxism) or TMJ dysfunction, the muscle can become enlarged, leading to:
• Facial tension or discomfort
• Jaw clicking or soreness
• Headaches and disrupted sleep
• A square or overly broad jawline
Botox works by relaxing the overactive masseter muscle, which eases the physical symptoms and gradually reduces the size of the muscle for a softer, more balanced facial contour.
Your Treatment at Youth Encore
At our Harley Street clinic, your treatment begins with a consultation to assess your facial structure, concerns, and goals. The procedure involves precise Botox injections delivered directly to the masseter using a fine needle.
What to expect:
• Quick, minimally invasive procedure (approx. 15–20 minutes)
• No downtime — most clients return to daily activities immediately
• Gradual jawline slimming over several weeks
• Symptom relief from bruxism and TMJ dysfunction
• Long-lasting results — typically 4–6 months, with longer duration after repeated sessions
Who Is This Treatment For?
You may be a good candidate for masseter Botox if you:
• Experience chronic teeth grinding, jaw tension or discomfort
• Have been diagnosed with TMJ (TMD) or bruxism
• Want to achieve non-surgical jawline slimming
• Prefer a softer, V-shaped facial contour
• Are seeking relief without invasive procedures or downtime
Our team treats each case individually, taking into account your health, facial anatomy and expectations.

FAQs
It is Botox that is specifically injected into the masseter muscle.
Botox that is carried out by an experienced professional is generally not painful. Some people do experience slight discomfort at the injection site, but this soon passes.
In general, we advise that Botox takes around two weeks to fully see the results from the injections. However, some people start to see changes within the first few days and a gradual ongoing improvement over the two weeks.
The number of injections that you have will depend on how large your masseter muscle is, or how severe your bruxism is. We are all unique, and we always treat each client as an individual.
Our experienced team will be able to assess the optimum amount of Botox needed for your enlarged masseter muscle to create the desired effect.
You should wait 3 to 4 months between Botox injections, but we will discuss your treatment plan with you when you come to our experienced team here at Youth Encore.
