Is Jaw Tension or Facial Slimming Your Concern? Exploring BTX for Masseter Management
In Singapore’s fast-paced, high-stress environment, it’s not uncommon for individuals to experience jaw tension, clenching, or even subconscious teeth grinding—particularly at night. These habits, often linked to stress or sleep posture, can lead to jaw discomfort, tension headaches, and even a visibly wider jawline due to enlarged masseter muscles.
At Asimont Clinic, we often consult with individuals seeking relief from these symptoms—or those looking to achieve a slimmer facial contour. In such cases, Botulinum Toxin (BTX) injections into the masseter muscles may be considered as a clinically guided, non-invasive solution.
Understanding the Masseter Muscle
The masseter is a powerful muscle responsible for chewing. It’s located at the back of the jaw, near the angle of the mandible. When overused, either through clenching or grinding (also known as bruxism), this muscle can enlarge over time, leading to:
- A bulky lower face or square jawline
- Jaw discomfort or fatigue
- Facial asymmetry
- Tension headaches
What Is BTX for Masseter Reduction?
BTX (Botulinum Toxin) works by temporarily relaxing the masseter muscle, reducing its activity. When injected with precision, this allows the muscle to gradually slim down over weeks, without compromising your ability to chew or speak.
BTX can be applied for two primary goals:
- Medical – To relieve symptoms of clenching, grinding, or tension
- Aesthetic – To soften a square jawline and achieve a more tapered or V-shaped facial profile
Common Signs You May Benefit from Masseter BTX
- Tightness or soreness at the jaw
- Audible teeth grinding during sleep
- Enlargement or squareness of the lower face
- Frequent tension headaches or ear discomfort
- Difficulty relaxing the jaw even when at rest
The Procedure: What to Expect
- Consultation & Assessment: We assess your jawline, facial structure, muscle bulk, and any functional symptoms.
- Treatment Planning: Dosage is customised depending on muscle strength and your aesthetic or medical concerns.
- Injection: A few small injections are administered directly into each masseter muscle using a fine needle. The procedure takes about 10–15 minutes.
- Aftercare: Minimal downtime. You may return to normal activities shortly after.
How Soon Are Results Visible?
- Functional relief from tension or clenching may begin within 1–2 weeks
- Aesthetic slimming generally becomes noticeable within 4–6 weeks, with continued refinement up to 8 weeks
Results typically last 4–6 months, with many patients returning for maintenance 2–3 times a year.
Can BTX Be Combined with Other Facial Treatments?
Yes. At Asimont Clinic, jawline slimming is often integrated into broader aesthetic plans that may include:
- Light-based therapy (BBL) to refine skin tone and reduce redness
- Hydrating skin treatments like RT Booster to improve texture and plumpness
- Chin or neck contouring using non-surgical modalities
These are planned according to your facial structure, lifestyle, and treatment goals.
Is the Procedure Painful?
Most patients report only minimal discomfort, likening the sensation to a light pinch. A numbing agent may be applied beforehand to enhance comfort.
Who Should Avoid Masseter BTX?
BTX may not be suitable if you:
- Are pregnant or breastfeeding
- Have a known neuromuscular condition
