Slimmer jawline, reduced clenching, restored comfort.
Masseter Botox is one of the most effective treatments for clients who struggle with jaw clenching, teeth grinding or a wider, more square-looking jawline. The masseter muscles sit on either side of the jaw and are responsible for chewing, but when they become overactive they can bulk up in size and create tension, headaches and facial discomfort. Masseter Botox offers a simple, targeted solution that softens muscle activity and creates both aesthetic and functional benefits.
What Is the Masseter Muscle?
The masseter is a strong, powerful muscle located at the angle of the jaw. When it becomes enlarged due to clenching, grinding or habitual tension, it can change the shape of the lower face, making the jaw appear wider and more masculine. Many clients also report waking with jaw pain, headaches or noticing damage to their teeth caused by long-term bruxism.
How Masseter Botox Works
A small amount of Botox is injected directly into the masseter muscle to relax excessive contractions. This helps reduce tension and gradually slims the appearance of the lower face as the muscle reduces in size over time. The treatment is quick, precise and requires no downtime. Most clients start to feel relief within a few days, with aesthetic results continuing to improve over the following weeks.
Key Benefits
• Slimmer, more contoured jawline
• Reduced teeth grinding and jaw clenching
• Relief from tension headaches and facial discomfort
• Softer, more feminine facial shape where desired
• Protects teeth from long-term grinding damage
How Long Does It Last?
Results typically last between three and six months depending on how strong the muscle is and how quickly your body metabolises the toxin. For clients who clench heavily, a couple of initial appointments may be needed to reach the ideal level of relaxation. With regular maintenance, the muscle becomes less active over time, leading to longer-lasting results.
Who Is This Treatment For?
Masseter Botox is suitable for anyone experiencing:
• A square or heavy-set jawline
• Teeth grinding or clenching (bruxism)
• Jaw tension, pain or stress-related clenching
• Headaches linked to jaw muscle overuse
It is also an excellent option for clients looking to create a more refined, V-shaped facial profile without surgery.
What to Expect
The treatment usually takes around 10–15 minutes and feels like a few small pinpricks. You can return to your normal routine straight away, although avoiding chewing gum and heavy workouts immediately afterwards is recommended.
