Masseter Botox | Treatment, Benefits, and Risks

Botox is a drug from a toxin generated by the Clostridium botulinum bacterium. The same toxin also brings on a potentially fatal food sickness called botulism. Doctors employ it in low doses to treat various health issues. From erasing wrinkles and fine lines to alleviating chronic medical conditions, the profound impact of Botox reaches far beyond the surface. Masseter Botox, commonly referred to as jawline slimming or jawline contouring, is one such technique that has grown in popularity. Masseter Botox has emerged as a transformative technique for redefining facial aesthetics and addressing concerns related to jaw muscle hypertrophy.

The following article will thoroughly examine every facet of this Botox procedure.

What is Masseter Botox and How Does it Work?

Masseter Botox, also known as jawline Botox or masseter reduction treatment, is a cosmetic procedure involving injecting botulinum toxin, a neuromodulator that temporarily inhibits muscle contractions into the masseter muscles of the jaw. These muscles control eating and jaw clenching, and when they become overactive, they can lead to a prominent and square-shaped jawline, often referred to as “jawline hypertrophy.” Masseter Botox temporarily relaxes these muscles, resulting in a slimmer, more contoured jawline appearance. It is minimally invasive and typically requires a series of injections over a few weeks to achieve the desired results.

What Are Masseter Muscles?

The masseter muscles are a pair of powerful muscles located on each side of the jaw, near the back of the lower jawbone (mandible). These muscles play a crucial role in chewing and grinding food by moving the lower jaw up and down. The masseter muscles are among the strongest muscles in the human body and are responsible for exerting the force needed to bite, chew, and clench the jaw. The masseter muscles originate from the zygomatic arch (cheekbone) and attach to the outer surface of the mandible.

When these muscles contract, they close the jaw by pulling the mandible upwards, allowing the teeth to come together for chewing and grinding. Apart from their functional role in chewing, the masseter muscles also contribute to the overall shape of the face and jawline. Overactivity or hypertrophy (enlargement) of these muscles can result in a more prominent and square-shaped jawline, which some individuals may seek to address through cosmetic procedures such as Masseter Botox to achieve a slimmer and more contoured facial appearance.

What Can be Treated by this Botox?

Masseter Botox, or jawline Botox, can effectively treat several aesthetic and medical conditions related to the masseter muscles. Some of the common issues that can be addressed using Masseter Botox include:

ConditionDescriptionTreatment Benefits
Jawline ContouringAchieve a refined, balanced jawlineReduction in masseter muscle activity leads to a slimmer and more appealing jawline appearance.
Jawline HypertrophyOverdeveloped masseter muscle causing square jawlineBotox relaxes and slims the muscle, resulting in a harmonious and softened facial profile.
Teeth Grinding (Bruxism)Involuntary grinding or clenching of teethBotox reduces muscle clenching, decreasing discomfort and potential damage from teeth grinding.
TMJ (Temporomandibular Joint) PainJaw pain, headaches, TMJ disorderMasseter Botox relaxes muscles, easing pressure on the jaw joint and providing relief from related symptoms.
Facial AsymmetryImbalance due to one larger or more active masseter muscleMasseter equalizes muscle activity, improving facial symmetry.
Migraine ReliefMigraines triggered by jaw muscle tensionBotox decreases muscle tension, potentially reducing frequency and severity of migraine headaches.

The Procedure of Botox for Masseter

The procedure for administering Botox for the masseter muscles involves several steps, from consultation to post-treatment care. Here’s a comprehensive guide to the typical process:

1. Pre-Procedure Plan:

  1. Consultation: Make an appointment for a consultation with a licensed physician specializing in cosmetic procedures. Discuss your concerns, goals, medical history, and expectations for the Masseter Botox treatment. The practitioner will assess your facial structure, muscle activity, and suitability for the procedure.
  2. Treatment Plan: Based on the assessment, the practitioner will create a personalized treatment plan. The plan outlines the recommended dosage of Botox, injection sites, and anticipated outcomes. Follow any specific guidelines provided by the practitioner before the treatment.
  3. Numbing or Cooling: On the day of the procedure, the practitioner may apply a numbing cream or provide a cold compress to minimize discomfort during the injections.

2. During the Procedure:

The treatment area will be cleaned thoroughly to ensure it’s free from makeup, oils, and debris. The dermatologist will inject Botox into targeted points within the masseter muscles using a fine needle. Your unique facial anatomy and treatment goals will determine the number of injections and specific locations.

Treatment Aftercare:

  • After the surgical procedure, you can get back to your regular activities. Avoid touching or massaging the treated area to prevent the unintended spread of Botox to other muscles.
  • The common side effects of mild bruising, redness, or inflammation at the injection sites subside within a few days.
  • It may take several days to a couple of weeks for the Botox effects to become noticeable. The masseter muscles will gradually relax, leading to a reduction in muscle size and improved jawline contour.
  • Schedule a follow-up appointment as the practitioner recommends to assess the results and determine if any adjustments are needed. 
  • To maximize the durability of the implications, maintain a good skin care regimen and shield your skin from the sun.

How Many Units of Botox for Masseter are Enough?

The quantity of units of Botox required for Masseter Botox treatment might differ greatly depending on aspects such as the individual’s anatomy, size of the masseter muscles, desired outcome, and the practitioner’s approach. On average, Masseter Botox treatment may require anywhere from 25 to 50 units per side (for a total of 50 to 100 units for both sides).

However, it’s important to note that Masseter Botox has no standard “one-size-fits-all” dosage. The exact dosage will be determined during the consultation. The practitioner will assess your unique facial structure, muscle activity, and treatment goals to determine the appropriate amount of Botox needed to achieve the desired results.

How Long Does This Botox Last?

The duration of the effects of Masseter Botox can vary from individual to individual, but on average, the results typically last around 3 to 6 months. After the initial treatment, you may notice muscle activity and jawline contour changes within a few days to a few weeks. The masseter muscles gradually relax over time, reducing muscle size and improving facial appearance.

The following variables can affect how long Botox for masseter therapy lasts:

  • Individuals with faster metabolisms may see the effects wear off more quickly.
  • The amount of Botox administered can impact how long the results last.
  • Each person’s response to Botox can differ due to genetics and other factors.
  • The duration of Botox effects can vary depending on lifestyle choices like smoking, sun exposure, and stress.
  • Regular follow-up treatments help maintain the results over time.

You can also choose the PDO threads technique in which threads are gently placed in target areas, such as the jowls, cheeks, jawline, and neck, help improve facial contours, tighten sagging skin, and restore volume.

What is Masseter Botox Cost?

The cost of Masseter Botox can vary significantly based on several factors, including the clinic’s location, the professional’s expertise, the clinic’s reputation, and the number of units of Botox required for your specific treatment. The average price per session can be anything from $400 to $1,200 or more. Since Masseter Botox involves a unique dosage for everyone, the total cost will depend on the number of units administered.
