About the procedure
When jaw width comes from muscle—not bone
Frequent chewing, clenching, or teeth grinding can make the masseter muscles at the sides of the jaw more prominent. Jaw Botox temporarily reduces their activity so the lower face can look less bulky as muscle volume gradually settles.
The procedure is more than matching injections on both sides. Careful planning considers muscle asymmetry, facial proportions, and areas prone to hollowing before the dose and injection points are selected.

FAQ
Frequently asked questions
Find out whether your jawline is muscle-dominant
Book a Jaw Botox consultation ↓
01When will my jawline start to look slimmer?+
Jaw Botox works by gradually reducing muscle activity and volume, so the contour change is not immediate. Timing and degree of change vary with your starting muscle size and daily habits.
02Is Jaw Botox painful?+
Most discomfort is a brief pinching sensation as the needle enters. Cooling anesthesia can be used, and you can discuss additional comfort needs during consultation.
03Can Jaw Botox cause hollow cheeks?+
Hollowing can occur when too much product is placed high in the masseter or close to the cheek. This is why the muscle boundary, facial anatomy, injection points, and dosage are assessed before treatment.
