A wide or square jawline can sometimes be a source of aesthetic concern for many. Often, this broader facial structure is due to overdeveloped masseter muscles, the powerful muscles used for chewing. This can result in a square face shape that some individuals find less than ideal for their appearance.
Beyond aesthetics, overactive masseter muscles may also cause functional issues like teeth grinding (bruxism), jaw tension, and even headaches. Fortunately, jaw botox offers a non-surgical solution to help achieve a slimmer jawline and address issues related to overactive masseter muscles, promoting both enhanced facial harmony and improved well-being.
What Is Jaw Botox?
Jaw botox involves injecting Botulinum Toxin directly into the masseter muscles located in the jaw. While Botox is a well-known brand name for Botulinum Toxin, the term “jaw botox” is commonly used to refer to this type of treatment regardless of the specific brand of Botulinum Toxin used.
It’s important to understand that this treatment is distinct from dermal fillers, which add volume, or facial slimming surgery, a more invasive procedure. Botox for jaw reduction works by temporarily blocking the nerve signals that cause the masseter muscles to contract. Over time, this reduced activity leads to a natural relaxation and, potentially, subsequent slimming of the muscle. This results in a softer, more V-shaped jawline.
Jaw Botox Overview
Considering masseter reduction with jaw-slimming botox? Here’s a quick look at what to generally expect:
- Average Sessions Required: 2 -3 initial sessions
- Duration of Results: 4-6 months
- Average Cost: SGD$600-$2,400
- Session Duration: 30 minutes
- Downtime: Minimal to none
Please note that the above information represents averages and will vary depending on individual conditions, the degree of muscle hypertrophy, and desired outcomes. A personalised consultation is essential for accurate expectations.
Why Consider Jaw Botox?
As mentioned above, there are many reasons why people choose to undergo jaw botox. Here’s more about the aesthetic and functional benefits that jawline botox may be helpful for:
Aesthetics & Facial Slimming
For individuals seeking a more refined facial contour, jaw botox may be a highly effective treatment. By relaxing the bulky masseter muscles, the treatment potentially subtly narrows the lower face, creating a more elegant and balanced V-shaped jawline. This enhanced facial symmetry can significantly boost confidence and self-esteem, helping individuals feel more comfortable and satisfied with their appearance.
Reduce Teeth Grinding & Jaw Clenching
Jawline botox may provide relief for individuals suffering from teeth grinding (bruxism) and jaw clenching. A study published by the National Library of Medicine suggests that botulinum toxin injections decreased muscle spasms and pain symptoms associated with nocturnal bruxism for up to approximately three months.
By weakening the masseter muscles, the intensity of these involuntary actions is reduced. This could lead to improved oral health by preventing tooth damage, alleviating jaw pain and tension, contributing to better sleep quality, and enhancing overall comfort.
Alleviate TMJ Dysfunction Symptoms
Temporomandibular joint (TMJ) dysfunction encompasses a range of conditions causing pain and impaired movement of the jaw joint and surrounding muscles. Jaw botox may help alleviate various TMJ dysfunction symptoms by relaxing the overactive masseter muscles that contribute to the problem.
A study published by the National Library of Medicine concluded that treatment can help alleviate joint clicking noise, headaches, pain when opening the mouth, and difficulty chewing to varying degrees. The extent of improvement can vary from person to person.
How Long Does It Last?
Understanding the longevity of jawline botox results is important for managing expectations. Typically, the effects of the treatment become apparent within two weeks following the injections and may last for approximately 4 to 6 months. This duration is influenced by various factors, including an individual’s metabolism, the initial strength and size of their masseter muscles, the dosage of botulinum toxin used, and their lifestyle habits.
It’s important to remember that jaw botox is not a permanent solution, as the muscles will gradually regain their original size and strength as the effects of the botulinum toxin wear off. To maintain the desired slimming effect, regular maintenance treatments are recommended.
However, for some individuals, repeated injections could cause the muscle to progressively shrink over time, potentially leading to a longer-lasting altered appearance if treatments are prolonged. Of course, this depends on the individual’s situation and needs, and consulting a medical professional is crucial to determine if this is a viable approach for your specific condition.
Is Jaw Botox Safe?
Jaw botox is considered a safe and potentially effective treatment for both cosmetic masseter reduction and functional purposes when performed correctly.
Brand & Administration by Medical Professional
The safety of jaw botox as a treatment for cosmetic and functional purposes is largely dependent on it being administered by a qualified and experienced medical professional. Therefore, it is of utmost importance to choose a licensed aesthetics medical clinic in Singapore or a reputable aesthetic doctor.
Botulinum toxin for the jaw is injected by a trained medical professional at V Medical Aesthetics. Furthermore, V Medical Aesthetics uses only HSA-approved botulinum toxin brands, Botox, Nabota, and Dysport, ensuring high standards of safety and efficacy for your jawline botox treatment.
Common Side Effects
The complication rate associated with jaw botox is low, especially when the procedure is performed by experienced aesthetic doctors. Common mild side effects include:
- Slight chewing weakness (temporary)
- Bruising (resolves in a few days)
- Redness
Note: Jaw Botox is not suitable for:
- Pregnant or breastfeeding women
- Individuals with neuromuscular disorders (e.g. myasthenia gravis, ALS)
Always consult a qualified medical professional to determine if this treatment is appropriate for you.

What to Expect During & After Jaw Botox
Before undergoing jaw-slimming botox, it’s helpful to know what to expect during the process and in the recovery period.
Pre-Assessment
During your pre-assessment at our aesthetics medical clinic, our experienced medical doctor will conduct a thorough muscle assessment, which may involve palpation of your masseter muscles while you clench your jaw. They will also discuss your cosmetic and medical goals to understand your desired outcome.
Jaw botox typically does not require anaesthesia. However, our experienced consultations will offer you the option of a topical numbing cream for added comfort, should you prefer it.
During Process
The injections are administered into the masseter muscles on each side of your jaw using a fine needle. Most patients report feeling only a mild stinging or pinching sensation during the injections, and the overall process is relatively quick and well-tolerated.
Aftercare
Following your masseter reduction treatment with jaw botox, it’s important to avoid massaging or applying pressure to the area for at least 24 hours to prevent the spread of the botulinum toxin to other muscles.
You should also avoid strenuous exercise and other facial treatments for the same period. Our medical doctors at V Medical Aesthetics will provide you with more detailed aftercare instructions and schedule a follow-up appointment to address any concerns you may have.
Jaw Botox vs. Jaw Surgery
When considering options for masseter reduction and jawline slimming, it’s important to understand the differences between jaw botox and jaw surgery. Jaw surgery is a more invasive procedure typically reserved for individuals with significant skeletal misalignments causing severe functional problems, such as difficulty chewing or speaking, or for major structural changes to the jawline. It involves surgically altering the bone structure of the jaw and requires significant downtime and recovery.
In contrast, jaw botox is a non-surgical, minimally invasive treatment that specifically addresses the masseter muscles. It is primarily chosen for aesthetic jaw slimming and for managing functional issues related to muscle hyperactivity, such as teeth grinding and mild TMJ symptoms. The recovery is usually minimal, and the results are temporary.
Ultimately, the best approach depends on the individual’s specific concerns, the underlying cause of a wide jawline, and their desired outcomes. It’s always advised to consult with a qualified professional who can assess your facial structure, goals, and recommend the most appropriate treatment.
