V-Shaped Face & Jaw Slimming Treatment with Botulinum Toxin in Singapore
Achieve a Sharper, More Sculpted Jawline—Without Surgery
A slim, V-shaped face is often associated with youth, elegance, and femininity. For individuals with a squarer or wider jawline, this ideal facial shape can be masked by bulky masseter muscles or a recessed chin.
At our clinic, we offer a personalised, non-surgical approach to facial contouring using botulinum toxin injections for jaw slimming and chin dermal fillers for structural enhancement. This dual-modality treatment helps to reduce the width of the lower face, improve chin projection, and restore balance to your facial profile—with minimal discomfort and downtime.
How the V-Shape Treatment Works
Jaw Slimming with Botulinum Toxin (Masseter Reduction) Botulinum toxin is carefully injected into the masseter muscles—the chewing muscles along the sides of the jaw. As these muscles relax and shrink over time, the jawline softens, creating a slimmer, more contoured appearance. This treatment can also help relieve symptoms of bruxism (teeth grinding) and jaw tension.
Chin Enhancement with Dermal Fillers Chin fillers are used to subtly enhance chin projection and lengthen the lower face, improving overall facial proportions. This creates a more defined and harmonious V-shaped contour.
What Is Jaw Slimming with Botulinum Toxin?
Jaw slimming with botulinum toxin—also known as masseter reduction or face slimming—is a non-surgical aesthetic procedure that helps to create a more tapered, V-shaped facial appearance.
The treatment involves precise injections of botulinum toxin into the masseter muscles, which are located at the sides of the jaw and responsible for chewing. In individuals with strong or bulky masseters, this can cause a wider, more square-shaped face. By relaxing these muscles, their activity and size gradually reduce over time, resulting in a softer, slimmer jawline.
This treatment has grown in popularity, especially in response to beauty trends that emphasise a more delicate and contoured lower face, as often seen in Korean and East Asian aesthetics. It is also commonly referred to as masseter botulinum toxin, V-face slimming, or jaw reduction treatment.
Benefits of Jaw Slimming with Botulinum Toxin
This non-surgical treatment offers both aesthetic enhancement and functional relief. Patients commonly experience the following benefits:
Aesthetic Benefits:
A slimmer, more contoured lower face
A sharper, more defined jawline
A V-shaped facial silhouette
A softer, less squarish appearance
Enhanced facial balance and symmetry
Functional Benefits:
Reduction in teeth grinding (bruxism)
Relief from jaw tension or discomfort
Potential improvement in tension headaches or TMJ-related pain
How Does Jaw Slimming with Botulinum Toxin Work?
Jaw slimming treatment works by targeting the masseter muscles, which are located on both sides of the jaw and are primarily responsible for chewing.
During the procedure, small amounts of botulinum toxin are carefully injected into these muscles. The neurotoxin relaxes the muscle over time, reducing its activity and strength.
As the masseter becomes less active, it gradually decreases in size—a process known as muscle atrophy. This reduction typically becomes noticeable within 3 to 4 weeks and contributes to a slimmer, more V shaped lower face.
The slimming effect is especially significant in individuals with strong squarish jaw muscles, often due to genetics or habitual teeth grinding (bruxism). Many patients also experience functional relief, such as reduced jaw tension or fewer episodes of clenching.
What to Expect During Jaw Slimming Treatment in Singapore
The jaw slimming treatment with botulinum toxin is a quick, comfortable, and non-surgical procedure. It’s performed in-clinic with minimal downtime, making it a popular choice for patients seeking a more contoured lower face.
Here’s what you can expect during and after your session:
🧊 Preparation
To ensure comfort and reduce the risk of bruising, ice packs are applied to the skin before treatment. This helps to numb the area naturally, so most patients experience little to no discomfort.
💉 Injection Process
Dr. Edwin will perform 3 to 4 precise injections into each masseter muscle using a fine needle. The goal is even distribution of the botulinum toxin, ensuring a natural slimming effect without affecting your ability to chew or speak.
Most patients describe the sensation as mild pinching or tiny ant bites—quick and very tolerable.
⏱ Duration of Treatment
The entire session takes under 10 minutes, making it convenient even for those with busy schedules.
⌛ Recovery & Results Timeline
You can return to normal activities immediately after treatment.
Some patients may experience mild aching, soreness, or tightness in the jaw over the next few days. This usually resolves on its own and is a normal part of the muscle’s response.
Jaw slimming effects typically begin to show in 2 to 4 weeks, with peak results around 4 to 6 weeks.
As the masseter muscles gradually shrink over time, the lower face appears slimmer, less squarish, and more V-shaped—creating a softer jawline.
🔁 Follow-Up & Maintenance
Around 4 to 6 weeks after treatment, patients may schedule an optional follow-up if they feel additional slimming is desired. During this review, Dr. Edwin will assess the results and determine if a touch-up is necessary to achieve optimal symmetry and contour.
To maintain your slimmer jawline, repeat treatments are typically recommended every 4 to 6 months, depending on how your body responds.
Jaw Botulinum Toxin for Bruxism and Teeth Grinding
Botulinum toxin is increasingly recognised as a safe and effective treatment for bruxism (teeth grinding) and jaw clenching—conditions that can lead to chronic jaw pain, headaches, and long-term dental damage.
Here’s how it works and how it can help:
🔹 Muscle Relaxation and Reduced Jaw Clenching
Botulinum toxin is injected into the masseter muscles, which are responsible for chewing and clenching. By partially relaxing these muscles, the treatment reduces their strength and overactivity. This decreases the force and frequency of grinding, especially during sleep, without affecting your ability to eat or speak normally.
🔹 Relief from Jaw Pain and Headaches
Chronic bruxism often causes tension in the jaw, headaches, and soreness along the temples or sides of the face. By limiting excessive muscle contractions, botulinum toxin can alleviate pain, jaw tightness, and fatigue, improving overall comfort.
🔹 Prevention of Tooth Wear and Damage
Long-term grinding can result in worn enamel, increased sensitivity, cracked teeth, or dental work failure. By controlling the underlying muscle activity, this treatment helps protect your teeth and may reduce the need for future dental repairs.
Is TMJ Botulinum Toxin the Same as Jaw Botulinum Toxin?
While the terms are often used interchangeably, TMJ botulinum toxin and jaw botulinum toxin technically refer to slightly different treatment goals.
TMJ refers to the temporomandibular joint, which connects your jawbone to your skull. In TMJ-related botulinum toxin treatment, the injections are still placed into the masseter muscles—not directly into the joint itself.
The difference lies in the intent:
TMJ botulinum toxin is typically used to relieve jaw tension, clenching, bruxism (teeth grinding), and other symptoms of TMJ disorders.
Jaw botulinum toxin (or masseter botulinum toxin) is primarily performed for aesthetic purposes, such as slimming a wide or square jawline.
That said, both treatments use the same technique and injection sites. Many patients benefit from both functional relief and aesthetic improvement after treatment.
Can TMJ or Jaw Botulinum Toxin Help with Headaches and Migraines?
Yes—botulinum toxin injections into the jaw muscles can help reduce tension headaches and migraines, especially when these symptoms are linked to jaw clenching or bruxism.
By relaxing the masseter muscles, botulinum toxin makes it more difficult to grind or clench the teeth. This reduces pressure on the temporomandibular joint (TMJ) and surrounding muscles, which can help alleviate headaches caused by chronic tension in the jaw.
In some cases, forehead tension or overactivity in the glabellar (frown) muscles may also contribute to migraines. When appropriate, additional botulinum toxin injections in these areas can complement jaw treatment and provide more comprehensive relief.
Post-Treatment Care After Jaw Slimming Botulinum Toxin Injections
While jaw botulinum toxin is a quick procedure with minimal downtime, following a few simple aftercare steps can help minimise side effects and support the best results.
Recommended Aftercare:
Avoid rubbing or massaging the treated area for at least 24 hours.
Refrain from strenuous exercise or intense facial movement (e.g. chewing gum, clenching) on the same day.
Apply a cold compress for 5–10 minutes post-treatment if needed to reduce redness or swelling.
Use an intensive recovery cream, as recommended by Dr. Edwin, to soothe the skin and support faster healing of any minor bruising or injection marks.
Stay upright for at least 4 hours after the procedure—avoid lying down flat immediately afterward.
These steps are simple but important in helping the botulinum toxin settle properly within the targeted muscles, while also minimising any unnecessary irritation.
Risks and Side Effects of Jaw Botulinum Toxin
When administered by an experienced and qualified doctor, jaw slimming with botulinum toxin is a safe and effective non-surgical procedure. However, like all medical treatments, there are potential side effects to be aware of.
Potential Side Effects:
Temporary Smile Asymmetry If the botulinum toxin is injected too close to the front of the jaw, it may affect the risorius muscle, which helps control facial expressions such as smiling. This can result in temporary asymmetry or weakness of the smile, which typically resolves as the effects wear off.
Mild Hollowing of the Cheeks In patients with leaner facial structures, injecting botulinum toxin too high on the masseter muscle may lead to a slightly hollow appearance in the mid-cheek area due to reduced muscle bulk. Proper placement helps avoid this.
Mild Jowling or Skin Laxity (in Select Patients) In rare cases, individuals with pre-existing skin laxity or minimal facial fat may notice mild sagging or jowling after the masseter muscle shrinks. This occurs when the facial structure lacks support following muscle reduction.
During consultation, Dr. Edwin will carefully assess your facial anatomy to determine your suitability for jaw slimming. If needed, complementary treatments such as non-surgical face lifting and tightening procedures like HIFU, or strategic use ofChinandJawline fillers, may be recommended to support a lifted, contoured appearance and minimise the risk of jowling.
Choosing an experienced injector is essential for safe results and balanced facial aesthetics. Dr. Edwin customises every treatment plan to minimise risks and enhance natural-looking outcomes.
Combining Jaw Slimming and Chin Fillers for a V-Shaped Face
While jaw slimming with botulinum toxin reduces the width of the lower face by relaxing the masseter muscles, chin fillers play a crucial complementary role by enhancing chin projection and length.
Together, these treatments create a more defined, contoured, and harmonious V-shaped facial profile.
What Are Chin Fillers?
Chin fillers are a type of dermal filler treatment used to sculpt and define the chin area. A gel-like substance—most commonly hyaluronic acid (HA)—is injected beneath the skin to increase volume, improve projection, and elongate the lower face.
Hyaluronic acid is a naturally occurring compound in the body that retains moisture and adds structural support. When precisely placed in the chin, it helps to:
Improve facial symmetry and balance
Enhance chin definition and length
Create a more proportionate and V-shaped appearance
This non-surgical procedure is especially beneficial for individuals with a recessed or under-projected chin, or for those seeking a more refined jawline without surgery.
What to Expect During Chin Filler Treatment in Singapore
🧑⚕️ Consultation and Planning
Dr. Edwin will first assess your facial proportions and discuss your aesthetic goals. Based on your individual anatomy, he will determine the ideal injection points to enhance chin projection and length while maintaining natural balance with the rest of your features.
❄️ Preparation
To minimise discomfort and reduce the risk of bruising, a cold compress is applied before each injection. This helps numb the area and improve comfort.
💉 Injection Process
The filler is injected using a fine needle or cannula at strategic points along the chin. Most patients describe the sensation as a small pinch or ant bite. The entire procedure is typically well tolerated and quick.
✨ Immediate Results
Results are visible immediately after treatment. The chin appears more projected and the lower face more elongated. While some mild swelling or bruising may occur, this usually resolves within a few days. Dr. Edwin may recommend a recovery cream to help support healing and reduce downtime.
⏱ Duration
The procedure takes approximately 15 to 30 minutes, making it a convenient option even for those with busy schedules.
How Long Do Chin Fillers Last?
Most hyaluronic acid (HA) chin fillers typically last between 9 to 18 months, depending on factors such as:
The specific filler product used
The degree of HA cross-linking (more cross-linked = longer-lasting)
Your body’s metabolism and how quickly it breaks down the filler
Lifestyle factors like exercise, sun exposure, and skincare habits
Repeat treatments are usually recommended once the effects begin to wear off, helping to maintain your desired profile and contour over time.
What Are the Possible Chin Filler Side Effects?
Chin filler treatment is generally well tolerated and safe when performed by an experienced medical professional. However, as with any injectable treatment, some temporary side effects may occur:
Mild swelling or bruising at the injection sites
Slight tenderness or pressure sensation in the chin area
Redness which usually resolve within 3 to 5 days
To aid healing, Dr. Edwin may recommend applying an intensive recovery cream to the treated area and avoiding pressure or massage for the first 24 to 72 hours.
If you experience any prolonged or concerning symptoms, you should contact the clinic for a prompt review.
Frequently Asked Questions (FAQ)
How Painful Are Jaw Slimming Botulinum Toxin Injections?
Most patients find the procedure very tolerable. The Botox injections are administered using fine needles, and a cold compress is applied beforehand to reduce discomfort. Most describe the sensation as a series of light pinches. Botox is well-tolerated and minimally invasive, with discomfort typically lasting only seconds.
When Will I See Results From Jaw Slimming Botulinum Toxin Injections?
Visible results typically appear between 2 to 4 weeks after the treatment, with optimal facial slimming effects seen around 4 to 6 weeks. Botox gradually reduces the size of the masseter muscles, leading to a more defined jawline.
How Long Do Chin Fillers Last?
Chin fillers typically last between 9 to 18 months. Duration varies depending on the type of filler used, the individual's metabolic rate, and lifestyle factors such as physical activity levels.
Can I Combine Jaw Slimming Botulinum Toxin With Chin Fillers?
Yes, combining Botox with chin fillers is a common approach to enhance facial proportions and contour. While Botox reduces jaw width by relaxing the masseter muscles, chin fillers project and elongate the lower face, helping to create a balanced V-shaped profile.
Will I Still Be Able To Chew Normally After Jaw Slimming Botulinum Toxin Injections?
Yes, normal chewing and speaking functions remain unaffected. Botox is used to relax overactive masseter muscles but does not interfere with essential jaw movements or daily function.
What Are The Side Effects Of Jaw Slimming Botulinum Toxin Or Chin Fillers?
Mild side effects such as bruising, swelling, or tenderness at the injection site may occur and usually subside within a few days. Botox and fillers are generally well tolerated, and adverse effects are rare when performed by an experienced medical injector.
Is There Downtime After Jaw Slimming Botulinum Toxin Injections Or Chin Fillers?
There is minimal to no downtime. Most patients resume work and daily activities immediately after the procedure. We advise avoiding strenuous activity and facial massages for the first 24 hours.
How Often Should I Repeat Jaw Slimming Botulinum Toxin Treatments?
Most patients repeat Botox treatments every 4 to 6 months to maintain results. With consistent sessions, the masseter muscles may shrink over time, allowing for longer intervals between treatments in the future.
Who Is A Suitable Candidate For Jaw Slimming Botulinum Toxin?
Jaw slimming with Botox is ideal for individuals with strong or bulky masseter muscles—commonly due to teeth grinding (bruxism), jaw clenching, or natural facial anatomy. A detailed facial assessment is essential to determine if this treatment is appropriate.
How Much Do Jaw Slimming Or Chin Filler Treatments Cost In Singapore?
The total cost depends on the number of Botox units or volume of filler required, based on individual muscle strength and facial goals. A personalised quote will be provided during your consultation.
What Is the Difference Between Jaw Slimming Botulinum Toxin and Jaw Surgery?
Jaw slimming with Botox is a non-surgical procedure that reduces the size of the masseter muscles to create a slimmer, V-shaped face. In contrast, jaw surgery (orthognathic surgery) involves bone reshaping and is typically reserved for structural issues or severe asymmetry. Botox offers a safe, quick, and reversible alternative with no downtime.
Can Jaw Slimming Botulinum Toxin Help With Teeth Grinding or Jaw Tension?
Yes. Botox is commonly used to treat bruxism (teeth grinding) and jaw clenching. By relaxing the masseter muscles, Botox can reduce jaw tension, prevent dental wear, and alleviate related headaches or jaw pain — while also providing aesthetic contouring benefits.
How Many Units of Botulinum Toxin Are Needed for Jaw Slimming?
The number of Botox units required varies based on individual masseter muscle size and strength. On average, patients may need between 20 to 40 units per side. A facial assessment is essential to determine the appropriate dose for optimal slimming and functional relief.
Can Men Undergo Jaw Slimming Botulinum Toxin Treatments?
Yes. Jaw slimming with Botox is suitable for both men and women. For male patients, the goal is often to reduce excessive jaw bulk while maintaining a defined and masculine contour. Treatment is tailored to individual aesthetic goals and facial structure.
How Do I Find the Best V-Shaped Face Treatment in Singapore?
Choosing the right clinic for jaw slimming or chin enhancement treatments is essential for achieving safe, natural-looking results.
When searching for the best V-shaped face treatment in Singapore, consider the following:
The clinic should be experienced in performing botulinum toxin and filler injections, with a strong understanding of facial anatomy and aesthetics.
Look for a doctor who offers customised treatment plans, rather than a one-size-fits-all approach.
A reputable clinic will take time to assess your facial structure, discuss your aesthetic goals, and explain the differences between options such as masseter botulinum toxin, chin fillers, and non-surgical lifting treatments like HIFU.
Ensure the clinic provides transparent information, proper aftercare instructions, and maintains a track record of safe outcomes.
At our clinic, Dr. Edwin personally assesses and performs all injectable treatments to ensure precision, safety, and natural results tailored to your unique facial profile.
