✨ What is Masseter Botox? ✨
Masseter Botox is a treatment that relaxes the masseter muscles — the strong jaw muscles on each side of your face. These muscles can become enlarged from clenching, grinding, stress, or genetics.
When Botox is placed into the masseters, it softens the muscle activity so you can still chew normally, but without the constant over-tightening.

💆♀️ What It Helps With:
• Jaw clenching / teeth grinding (TMJ symptoms)
• A bulky or square jawline
• Facial slimming
• Tension headaches
• Night-time grinding
⸻
🔬 How It Works:
Botox temporarily blocks the signals that tell the masseter muscle to contract. Over the next 2–4 weeks, the muscle relaxes and reduces in size. This creates a softer jawline and decreases tension.
⸻
⏱ How Long It Lasts:
Results typically last 4–6 months. With consistent treatments, the muscle shrinks and holds results longer.

💡 Bonus: Zero downtime. You can go right back to your day!
