The Skiin Approach
Jaw tension, clenching and teeth grinding — often felt in and around the TMJ, the jaw joint — is driven by an overactive masseter muscle, the powerful chewing muscle at the angle of the jaw. Night guards protect your teeth, but they don't treat the muscle doing the damage.
Masseter Botox does. Precise injections into the masseter relax the overactive muscle — easing clenching and grinding, softening tension headaches, and gently slimming a square lower face over time as the muscle rests.
Because the masseters frame the lower face, your doctor assesses your facial structure as well as your symptoms, so the treatment relieves tension while keeping your face in balance.
The Result
Results typically last 3–4 months, often longer with repeat treatment as the muscle becomes less active over time.
Signs we treat
Tension headaches and morning jaw pain are classic signs of overnight clenching — the masseter works while you sleep.
Grinding progressively wears the teeth. Relaxing the muscle protects them from further damage.
A jaw that feels tight, tired or locked by the end of the day — often around the TMJ joint — responds as the overactive muscle is allowed to rest.
Enlarged masseters widen the lower face. Treating them gently slims a square jawline over time — a change your doctor plans for in advance.
The Journey
Step 1
Doctor's assessment
Your doctor examines your masseter muscles, reviews your symptoms and facial structure, and prescribes a tailored dose.
Step 2
Treatment
Precise injections into the masseter muscle — quick, comfortable and with no downtime.
Weeks 1–2
The muscle relaxes
Clenching and grinding reduce as the muscle rests, and tension headaches and jaw ache begin to ease.
Ongoing
Maintenance
Results typically last 3–4 months. Your doctor will advise when a repeat treatment would keep the muscle — and your jaw — comfortable.

FAQs
They're closely linked. TMJ is the temporomandibular joint — the jaw joint — and pain or tension there is often called TMD. Clenching and grinding overload the joint and the masseter muscle, which is why jaw tension, TMJ pain and tension headaches often travel together. Masseter Botox treats the muscle driving the strain.
Precise injections into the masseter — the large chewing muscle at the angle of the jaw. Relaxing the overactive muscle eases clenching and grinding, softens tension headaches, and gently slims a square lower face over time.
Common signs are waking with jaw ache or headaches, worn-down teeth, tension in the jaw, or a widening lower face. Many people grind at night without realising — a doctor's assessment confirms whether the masseter muscle is overactive.
Typically 3–4 months for first treatments, and often longer with repeat treatment as the muscle becomes less active over time. Results vary between individuals.
If your masseters are enlarged from clenching, relaxing them gently slims a square lower face over time. Your doctor assesses your facial structure first so the change is harmonious, never drastic.
It relaxes the overactive muscle so clenching and grinding are significantly reduced — easing jaw ache, tension headaches and tooth wear. Your doctor will set realistic expectations at your consultation.
Yes, when prescribed and administered by a qualified doctor. At Skiin, treatment is doctor-led from assessment through to review, with the dose tailored to your muscle strength and goals.
Cost depends on the dose your doctor prescribes, which is determined by the size and strength of your masseter muscles. Everything is discussed transparently at consultation before you commit to anything.
