Masseter Botox® is a treatment that targets the masseter (chewing) muscle to create a more aesthetically-pleasing jawline contour.

Botox is popularly known as a wrinkle-smoothing injectable, often used to minimize the appearance of crow’s feet and forehead lines. It works by limiting activity in active facial muscles, smoothing away wrinkles caused by muscle contractions. Botox in masseter muscle also softens the look of a square jawline to produce a slimmer, more refined face shape.

100% of Laser & Skin Surgery Center of New York’s treatments are performed by board-certified dermatologists who have extensive experience with injectables, including Botox. When you come to us for cosmetic care, you can be confident that you can safely achieve a perfectly natural look.

The masseter muscle is a powerful facial muscle that wraps around the jawbone, connecting your lower jaw to your cheek. Its job is to help open and close the jaw while you’re chewing and talking. 

When this muscle becomes enlarged – typically in individuals who habitually clench and grind their teeth – it can transform an oval face shape into one that is square and masculine. It may also cause one side of the jaw to appear more prominent than the other, causing facial asymmetry. 

When Botox is injected into the masseter muscle, it will temporarily block nerve signals to the muscle. The muscle relaxes and shrinks, changing the shape of an overly square face into a more feminine V-shape. 

In addition to contouring the jawline, masseter Botox may reduce discomfort caused by persistent grinding and clenching. This will benefit those who suffer from headaches and other symptoms due to an overactive masseter muscle.

Masseter Botox treatments are generally considered safe. However, temporary side effects can occur, such as:

• Bruising
• Swelling at the injection site
• Headaches
• A crooked smile
• Uneven appearance

You can significantly reduce your risk for side effects and ensure optimal results by working with an experienced, board-certified dermatologist.

Masseter Botox injections to the jawline require no downtime. After your treatment, you can resume your usual activities. 

It is recommended to avoid the following for the first 24 hours following treatment:

• Rubbing or placing pressure on the injection sites
• Bending or lying down (for the first 4 hours)
• Exercising or other strenuous activities 

These activities might promote swelling or bruising. They can also lead to Botox migration to other parts of the face. It is best to allow the injectable to settle for the first day to ensure an optimal outcome.

Some people start seeing results within 1 to 3 days, and you can expect to see full results in about 1-2 weeks.

The actual masseter Botox cost varies depending on factors like where you live, how much Botox you need, and your injector’s qualifications. You can determine the total cost of your treatment during your consultation. Keep in mind that you can’t put a price on experience and expertise, so always seek treatments from the most qualified injectors to ensure a safe and successful procedure.

Botox Cosmetic treatments are considered elective procedures that are ineligible for insurance coverage.
