Facial Slimming with Masseter Botox: A Non-surgical Option
Do you feel like your face looks too square or wide? Do you grind your teeth or clench your jaw, especially when stressed? You may have enlarged masseter muscles. Masseter Botox is a safe, non-surgical treatment that relaxes these muscles and creates a slimmer, more contoured jawline.
What Is Masseter Botox?
Masseter Botox involves injecting small amounts of botulinum toxin into the masseter muscles, located at the angle of the jaw. These muscles are responsible for chewing and can become enlarged from habits like clenching, grinding (bruxism), or frequent gum chewing. Over time, this muscle growth can change your facial shape and cause symptoms like jaw tension or headaches.
Botox works by temporarily relaxing the masseter muscles. As the muscles shrink from decreased use, the lower face becomes softer and more V-shaped. This is especially popular among patients looking for facial slimming or relief from jaw discomfort.
Who Is a Good Candidate?
Masseter Botox is ideal for:
• Patients with a square or bulky jawline from muscle, not bone
• Those experiencing jaw tension, teeth grinding, or TMJ discomfort
• Anyone wanting facial contouring without surgery
• People seeking a more feminine or heart-shaped facial profile
This treatment is safe for both men and women. Results are customized based on your anatomy and goals.
What to Expect
Procedure: The treatment takes about 10 to 15 minutes. No numbing is needed. Most people find it very tolerable.
Downtime: None. You can return to work or normal activities right away.
Results: Subtle changes begin around 2 to 4 weeks. Maximum slimming is seen by 8 to 12 weeks. Results typically last 4 to 6 months, sometimes longer with repeat treatments.
Maintenance: Many patients return twice a year to maintain their results.

Common Questions
Will it affect my ability to chew?
No. The goal is to reduce muscle bulk, not stop normal function. You may feel mild fatigue when chewing tough foods at first, but this usually resolves quickly.
How many units will I need?
It varies depending on the strength and size of your masseter muscles. On average, 20 to 40 units per side are used. Your provider will assess your anatomy and recommend a tailored dose.
Is it safe?
Yes, when performed by an experienced, board-certified dermatologist. Side effects are rare and usually mild, such as tenderness or minor bruising at the injection site.
