Masseter Botox, also known as jaw reduction or masseter reduction, often requires 40+ units per jaw. Given the size of the investment, clients are often curious how long Masseter Botox treatments last. In this post, we'll explore the longevity of Botox for masseters, the factors that influence its duration, and how you can maintain your results.

Masseter Botox Treatment Area For 40 Units Lasts 3 To 6 Months

First, let's Understand Masseter Botox

What Is Masseter Botox?

The masseter muscles are the prominent muscles located at the angle of your jaw that are responsible for chewing and clenching. Enlarged masseter muscles can lead to a square-shaped jawline, which some people may find aesthetically undesirable. Botox injections can help relax these muscles, resulting in a softer, more tapered jawline and relief from clenching and grinding. Enlarged masseter muscles can be caused by genetic factors, habitual teeth grinding (bruxism), or excessive chewing. This condition can contribute to a bulky jawline and can also cause discomfort or pain in the jaw area.

How does Botox for Masseters Works?

Botox temporarily relaxes the muscles it is injected into. When injected into the masseter muscles, Botox relaxes these muscles, reducing their size and activity. This results in a slimmer jawline and can also alleviate symptoms of bruxism and TMJ disorder. The injection process for masseter Botox is quick and minimally invasive. Your provider will use a fine needle to inject Botox into specific points in the masseter muscles. The entire procedure typically takes just a few minutes and is relatively painless.

Next, let's discuss Masseter Botox Longevity

Initial Masseter Tox Results and Peak Effect

  • Initial improvements may be noticeable after 2-3 days for some clients
  • More commonly, results become visible after about 7-10 days
  • The full effects usually develop over 2-4 weeks
  • Peak effect is typically reached around the 12-week (3 month) mark

Average Duration For Masseter Botox

  • On average, masseter Botox lasts 3-6 months
  • Most patients need re-treatment after 4-6 months to maintain results

Factors Affecting Duration

  • Number of Tox units injected - higher doses tend to last longer
  • Client metabolism and muscle strength
  • Frequency of treatments - effects may last longer with repeated treatments over time

Lastly, Here's Tips To Maximize Treatment Longevity

Follow Post-Treatment Instructions

Following your provider’s post-treatment care instructions is crucial for maximizing the longevity of your Botox results. This may include avoiding strenuous activity, not rubbing the treated area, and staying upright for a few hours after the injection.

Maintain a Consistent Treatment Schedule

Scheduling regular Botox treatments every 4 to 6 months can help maintain your results and prevent the return of a bulky jawline or symptoms of bruxism. Over time, consistent treatments can even lead to longer-lasting effects as the muscle becomes conditioned to remain relaxed.

Healthy Lifestyle Choices

Adopting healthy lifestyle habits can also contribute to longer-lasting Botox results. These include:

  • Avoiding Excessive Chewing: Limiting activities that overwork the masseter muscles, such as chewing gum or tough foods, can help maintain results.
  • Stress Management: Reducing stress can decrease habits like teeth grinding, which contributes to masseter hypertrophy.
  • Proper Oral Care: Using night guards or other dental devices as recommended by your dentist can help manage bruxism.

Use of Complementary Treatments

Combining Botox with other treatments can enhance and prolong your results. For instance, using dental devices to manage bruxism or other cosmetic treatments for overall facial aesthetics can complement the effects of Botox.

Is Botox for Masseters Right for You?

Determine Your Goals

To determine if this treatment is right for for you, you should determine your goals (e.g. cosmetic or paid reduction), share with your qualified provider and receive a full consult.

Consult With a Qualified Professional

During your consultation, your provider will evaluate your facial anatomy, discuss your aesthetic goals, and determine the appropriate number of Botox units for your specific needs. This is also a good time to address any concerns or questions you may have about the procedure.

Address Any Tox Safety Concerns

Botox is an FDA approved treatment which is generally a safe and effective treatment for most people looking to reduce the size of their masseter muscles and achieve a slimmer jawline. However, it’s important to have a thorough consultation with a qualified provider to ensure it’s the right option for you, especially if you have any underlying health conditions or are taking certain medications.
