Another use for anti-wrinkle injections this time to slim the face

Masseter Botox is a unique treatment that not only addresses facial aesthetics but is also a remedy for some common jaw-related discomforts.

Masseter Botox involves the use of anti-wrinkle injections, a well-known muscle relaxer, into the masseter muscles, which are important muscles located near the cheekbones that help you chew. By blocking nerve signals in the masseter, the muscle becomes temporarily paralyzed, offering a host of benefits including changing face shape and managing facial pain.

Understanding the Masseter Muscle and Botox

The masseter muscle, located on the side of your face, extends from your cheekbone to your lower jawbone and plays a vital role in the chewing process. It is one of the strongest muscles in the body and is activated every time you bite into your favourite meal or grind your teeth in concentration.

But, what happens when this muscle becomes overactive, leading to discomfort or a square jaw appearance? This is where anti-wrinkle injections come into play. Anti-wrinkle injections are neurotoxins that are widely known for their use in smoothing wrinkles and fine lines. It functions as a muscle relaxer, temporarily paralyzing the target muscles by blocking the nerve signals that cause them to contract.

When anti-wrinkle injections are placed into the masseter muscle, a treatment known as Masseter Botox or Jaw Botox, it eases the muscle's constant activity. Unable to contract fully, the muscle relaxes, leading to a softening of the jawline and a decrease in discomfort related to overactivity.

Uses of Masseter Botox: Beyond Aesthetics

The allure of Masseter Botox lies not only in its capacity to transform one's facial aesthetics but also in its therapeutic benefits.

Reduces Teeth Grinding

Teeth grinding, also known as bruxism, can lead to a tight jaw, facial pain, tooth sensitivity, headaches, and even tooth damage. Traditional treatments typically involve mouthguards and lifestyle changes, but these might not be effective for severe cases. Masseter injections offer a more potent solution. As the toxin weakens the masseter muscle, it relaxes the jaw, reducing involuntary clenching and grinding.

Reduces Symptoms of Temporomandibular Joint Disorder (TMD)

Temporomandibular Joint Disorder, or TMD, is a condition that affects the hinge connecting your lower jawbone to your skull. It often coexists with bruxism and can cause symptoms such as jaw pain, poor range of motion in the jaw, headaches, and jaw locking. Masseter injections can help relieve these symptoms by relaxing the masseter muscle, thus alleviating the strain on the Temporomandibular Joint.

Facial Contouring

For those seeking a cosmetic benefit, anti-wrinkle injections offer a non-surgical approach to facial contouring. Overly active masseter muscles can give the face a square shape. By reducing the size of the masseter muscle a slimmer, more V-shaped jawline is formed, adding a soft, feminine touch to the face.

What to Expect During Your Jaw Botox

The thought of any medical procedure can be intimidating, but understanding the steps involved in Masseter anti-wrinkle injections can ease any apprehensions and prepare you for what to expect.

Before the Procedure

The journey to Masseter injections starts with a consultation with a medical professional. This step is crucial as it allows the practitioner to understand your goals and concerns, and assess your jaw and face. This information will guide them in determining the injection site and the number of units needed. It is important to note that the actual procedure takes place in a doctor's office; no hospital visit is required.

During the Procedure

The procedure itself is relatively straightforward and quick. Here's what you can expect:

  • A medical professional will clean your skin to reduce the risk of infection. They may also apply a topical anesthetic to numb the area.
  • They will then prepare a syringe with the neurotoxin. The syringe will have a very thin needle to minimize discomfort.
  • The needle is inserted into your masseter muscle, and the toxin is slowly injected as the needle is withdrawn.
  • Depending on the treatment plan, the procedure may be repeated on the other side of your face.

The entire procedure typically lasts only about 15 minutes.

After the Procedure

One of the advantages of anti-wrinkle injections in general is the minimal recovery time. You can return to your usual activities right after the procedure. However, for the first 24 hours post-treatment, you should avoid:

  • Rubbing the treated area
  • Placing pressure on the treated area
  • Engaging in vigorous exercise

These precautions are necessary to prevent the toxin from spreading to other parts of your face. 

It typically takes about a week to see the full results, but some people may start noticing changes within 1 to 3 days. Keep in mind that the effects of anti-wrinkle injections are temporary, usually lasting between 3 to 4 months. If you wish to maintain the results, the procedure will need to be repeated.

Potential Risks and Side Effects of Masseter Botox

Despite the many benefits of Masseter Botox, it is important to be aware of its potential risks and side effects. Like any medical procedure, it is not without potential complications, although these are generally rare and mild.

The most common side effects include:

  • Pain or swelling at the site of injection
  • Bruising
  • Headache
  • Flu-like symptoms

Less commonly, some people may experience a crooked smile or drooling, which is only temporary.

It's also important to note that anti-wrinkle injections should be avoided by certain individuals, such as those who are pregnant or breastfeeding. Always disclose your full medical history to your doctor before undergoing any treatment.
