Medical Directors note - “Jaw Botulinum Toxinis a quick, safe and effective treatment that reduces the size of the masseter muscle to give the face a slimmer V shape appearance. Jaw Botulinum Toxinalso provides relief from jaw clenching, teeth grinding and Temporomandibular Joint dysfunction.”
For many men and women, an overdeveloped jaw muscle (masseter) results in a broad and squarish face shape that appears unattractive. Jaw Botulinum Toxin, or masseter reduction with botulinum toxin, is a minimally invasive solution that can help slim the face to achieve a more refined and balanced appearance.
An overactive jaw muscle (masseter) may also lead to functional issues such as teeth grinding (bruxism), jaw tension, temporomandibular joint (TMJ) dysfunction, headaches and migraine. In this article, we’ll discuss jaw Botulinum Toxin, how it works, its benefits, and what you should expect during the treatment process.
What is Jaw Botulinum Toxin?
This is a procedure where botulinum toxin is injected into the masseter muscles, the muscles located on either side of your jaw responsible for chewing. These muscles can become overdeveloped due to genetics or habitual activities such as teeth grinding, creating a square or wide jaw appearance.
When botulinum toxin is injected into the masseter, it will temporarily reduce the masseter’s activity, relaxing the muscle over time. With relaxed muscles, the jawline appears slimmer and more contoured, relieving symptoms associated with overactive masseter muscles, such as jaw tension and teeth grinding.

Benefits of Jaw Botulinum Toxin
Jaw Botulinum Toxin Masseter Reduction is indicated for the following aims:
Facial contouring and slimming
For individuals with a square jawline and broad face, jaw Botulinum Toxin reduces the bulk of the masseter muscle which in turn slims down the lower face, creating a more oval or V-shaped contour. This reshaping effect can be particularly appealing to those who feel their facial structure is too masculine or broad. Jaw Botulinum Toxin is hence nicknamed the “face slimming injection” or “V shape face injection”
Relief from Teeth Grinding and Jaw Clenching
Bruxism, a condition in which individuals grind their teeth or clench their jaws, can lead to significant discomfort and wear and tear of teeth. Jaw Botulinum Toxin temporarily relaxes the masseter muscles, reducing the frequency and intensity of these habits. This not only protects the teeth but also alleviates related symptoms such as tension headaches and jaw pain.
TMJ Pain Relief
The temporomandibular joint (TMJ) connects the jaw to the skull and can become inflamed or strained due to overactive masseter muscles. Botulinum Toxin injections into these muscles relieve tension, helping to alleviate pain, jaw stiffness, and even clicking or popping sounds associated with TMJ disorders.
What to Expect During and After the Treatment
The jaw Botulinum Toxin procedure is straightforward, with minimal preparation or downtime. During the initial consultation, your doctor will assess your facial anatomy and masseter size and discuss your desired result. On the day of the procedure, the treated area will be cleansed, and an ice pack may be applied to enhance comfort.
The injections are administered using a fine needle and take only a few minutes to complete. Most patients only feel a slight pinching sensation during the process, but it is generally well-tolerated and not painful.
After the procedure, you can go back to doing your normal activities, although you should avoid rubbing the injection site or engaging in strenuous physical activities for at least 24 hours.
Your desired jawline transformation will unfold over several weeks, with changes becoming progressively more noticeable. Knowing what to expect at each stage can help you track your progress and appreciate the treatment's subtle yet impactful effects.
Week 1–2: Initial Effects
During the first week or two following your treatment, you may notice a reduction in muscle tension in the jaw area. Decreased muscle tension is especially beneficial for individuals with jaw discomfort, teeth grinding, or tension headaches, as the masseter muscles relax.
However, visible slimming of the jawline is usually not apparent at this stage since the muscle atrophy process has just begun.
Week 4: Visible Changes
By the fourth week, the effects of Botulinum Toxin become more pronounced. The masseter muscles, having been less active for several weeks, start to shrink, leading to noticeable jawline slimming.
Many patients find this stage exciting as the contours of their lower face begin to look softer and more balanced. Functional improvements, such as reduced grinding and clenching, are also more evident at this point.
Months 3–6: Peak Results
The most dramatic results typically occur between the third and sixth months. By this time, the masseter muscles have undergone significant atrophy, revealing a more refined and contoured jawline. This is the stage when the full aesthetic impact of the treatment is visible, often enhancing overall facial harmony and symmetry.
For those addressing functional issues, this period also represents the peak of relief from jaw pain, tension, or related symptoms.
Maintenance: Sustaining Your Results
The effects from Jaw Botulinum Toxin are temporary and need to be maintained. The botulinum toxin wears off over time, and the masseter muscles will gradually regain activity. Most patients find that the results last approximately 4–6 months.
We recommend repeat treatments to maintain the desired aesthetic and functional benefits. Regular maintenance sessions sustain the slimming effect and may also lead to longer-lasting results over time as the muscles continue to weaken with consistent treatment.
Side Effects
Jaw Botulinum Toxinis generally safe, but some potential side effects include:
Mild swelling, redness, or a little bruising at the injection site.
Rare cases of facial asymmetry from unintended diffusion of botulinum toxin to involve the muscles of facial expression
Choosing a qualified and experienced provider minimises these risks and ensures optimal results.
Does the Brand of Botulinum Toxin Matter?
The effectiveness of jaw Botulinum Toxin depends on several factors such as dosage, the precision of injection and patient factors such as masseter muscle size and expectations. In Singapore, four brands of Neurotoxins are approved for - Botulinum Toxin®, Dysport®, Nabota® and Xeomin®.
While all brands are effective, slight variations in formulation can affect diffusion, onset of results, and longevity. With repeated usage of a particular brand of botulinum toxin, neutralising antibodies may develop which affect the outcome of treatment and require a change of brand. During the treatment, your provider will discuss the subtle differences between brands and recommend the best brand for your needs, ensuring optimal results. At Bay Aesthetics Clinic, all four locally approved brands of botulinum toxin are available at the same price, ensuring that you get the treatment you need without worrying about cost.

Who is not a good candidate for masseter Botulinum Toxin?
Masseter Botulinum Toxin is unsuitable for pregnant or breastfeeding individuals, those with neuromuscular disorders, allergies to Botulinum Toxin ingredients, or someone with an unrealistic expectation.
Can I combine jaw Botulinum Toxin with other treatments?
Jaw Botulinum Toxin can be paired with treatments like dermal fillers or skin tightening procedures such as Ultherapy or Oligio RF to enhance overall facial aesthetics and symmetry.
What happens if I stop doing Jaw Botulinum Toxin?
After the Botulinum Toxin treatment loses its effect in 4-6 months, the jaw muscle gradually returns to its original size and symptoms of teeth grinding and jaw clenching may recur. There is no long-term effects from Jaw Botulinum Toxin.
Does Jaw Botulinum Toxin cause the face to sag?
This depends- for older clients (40-50 years old and above) with some skin laxity, the reduced size of the masseter muscle may make facial sagging appear to be more obvious- these individuals can consider skin tightening and face lifting treatments such as Ultherapy. For younger clients (below 40 years old) typically there is enough skin elasticity and firmness and there is no visible facial sagging after jaw Botulinum Toxin.
Does Jaw Botulinum Toxin correct facial asymmetry?
Facial asymmetry may be due to uneven size of masseter muscles or jaw bone structure- if the cause is due to a difference in the size of jaw muscles, then Jaw Botulinum Toxin may be able to help.
