Jawline Slimming with Botox

Jawline slimming with Botox targets the masseter muscle — the powerful chewing muscle on each side of your jaw. When this muscle is overdeveloped (often from teeth grinding, clenching, or genetics), it creates a wider, more square-shaped lower face. Botox injections relax the masseter, allowing it to gradually slim down and create a more contoured, V-shaped jawline.

Beyond aesthetics, masseter Botox is highly effective for bruxism (teeth grinding) and TMJ-related jaw tension. Many clients seek this treatment primarily for pain relief and wake up with the cosmetic benefit as a welcome bonus. Reduced grinding also protects tooth enamel and decreases morning headaches.

The treatment involves 3 to 5 injection points on each side of the jaw, targeting the bulk of the masseter muscle. The entire procedure takes about 15 minutes. Because the masseter is a thick muscle, slightly higher doses (25 to 50 units per side) are used compared to facial wrinkle treatment.

Slimming results develop gradually over 4 to 8 weeks as the muscle mass reduces. The effect on grinding and jaw tension is often noticeable sooner — within 1 to 2 weeks. Results typically last 4 to 6 months, and many clients find the muscle naturally becomes smaller with repeated treatments, requiring less product over time.

At Templus Life we assess your facial proportions, bite alignment, and masseter muscle strength before treatment. This ensures we deliver the right amount of product to achieve a harmonious, natural result that complements your overall facial structure.
