What is jaw reduction
Jaw Reduction is a tailored botulinum-toxin treatment of the masseter — the muscle that closes your jaw. When this muscle is over-developed (genetics, clenching, gum chewing), it widens the lower face. Relaxing it allows it to atrophy with disuse, narrowing the jaw without touching bone.
What to look for in a doctor
- A medical injector who palpates the masseter at clench to confirm muscle (not bone) hypertrophy.
- Dose decided in units per side based on muscle bulk, not a flat package price.
- Photographs at consultation, 4-week review and 12-week review.
- Honest counsel — if your wide face is mostly bone, a good injector will tell you a non-surgical result will be limited.
Frequently asked
- How is this different from masseter botox?
- It is the same medicine. Jaw reduction simply refers to the aesthetic goal — slimming the lower face — with dose and pattern optimised for narrowing, not just relaxation.
- Will I look hollow?
- Not at correct dose. Hollowing happens when the same patient is over-treated for years without rest periods. A good injector will adjust dose down over time.
- How much narrower will my face look?
- Most patients see 3–7 mm of width reduction per side at peak effect. Visible to you and close friends, subtle to others.
- Is it permanent?
- No. The muscle will return if untreated, but typically to a smaller baseline than before.
- Can I combine it with chin or jawline filler?
- Yes — combining muscle relaxation with chin projection often gives the most refined result. Done in the same session or staged 2 weeks apart.
