“Masseter injections provide dual benefits. By relaxing overworked jaw muscles, patients get dramatic relief from TMJ soreness and teeth grinding, while naturally slimming the lower face contour over 4 to 6 weeks.”

Therapeutic & Aesthetic Benefits

The masseter muscle is one of the primary muscles used for chewing. Hyperactive masseter muscles caused by stress or nighttime clenching can result in chronic jaw pain, tension headaches, and an overly square jawline. Injecting Botox or Xeomin relaxes the muscle, reducing painful tension and slimming the lower third of the face over time.

Dosage and Timeline

Masseter treatment requires larger dosages than delicate facial areas, typically 20 to 30 units per side (40 to 60 units total). Pain relief often begins within 1 to 2 weeks, while visual jaw slimming manifests between 4 to 8 weeks as the muscle decreases in bulk. Results last approximately 4 to 6 months.
