Masseter Botox in Irvine, CA — Jaw Slimming by Dr. Sabeen Munib, MD
If you grind your teeth at night, wake with jaw tension, or want a softer, more oval facial shape — masseter Botox addresses all three. It's one of the most effective and lasting facial transformations available without surgery.
Dr. Munib performs every masseter injection personally, calibrating each side independently. Masseter hypertrophy is frequently asymmetric — treating both sides with the same dose produces a balanced result. Treating them the same regardless produces a smaller version of the same asymmetry.
Physician-Performed. Every Time.
Dr. Sabeen Munib, MD — MD with 15+ years in aesthetic medicine in Orange County.
No injections are delegated at Spectrum Skin Clinic. Dr. Munib assesses each masseter muscle independently by palpation, determines the appropriate dose per side, and performs every injection personally.
- Physician-only — every injection performed personally by Dr. Munib
- Bilateral assessment — each side evaluated and dosed independently
- Conservative starting dose with reassessment at 4–6 weeks
- Treats bruxism as a medical condition, not just a cosmetic concern
"Dr. Sabeen was extremely knowledgeable and helpful in guiding me through the best way to refresh my appearance. She thoroughly explained all options." — Denise
What Masseter Botox Can Do For You
Masseter Botox delivers two distinct benefits — and many patients come for one and discover the other.
- Jaw slimming — the lower face narrows, the jaw angle softens, facial shape shifts from square to oval over 6–8 weeks
- Bruxism relief — jaw clenching force is reduced, resolving morning jaw pain, headaches, tooth wear, and TMJ inflammation
- Asymmetry correction — independent dosing per side produces a more balanced lower face
- Long-term results — with regular maintenance, the masseter reduces progressively and results extend
Jaw Slimming & Facial Contouring
The lower face narrows, the jaw angle softens, and facial shape shifts from square to oval or heart-shaped over 6–8 weeks. One of the most visible transformations available without surgery or filler.
Bruxism & TMJ Relief
When the masseter is relaxed, it can no longer generate the full clenching force causing morning jaw pain, chronic headaches, tooth wear, and TMJ inflammation. Many patients come for aesthetics and discover significant pain relief.
Lower Face Rebalancing
Independent bilateral assessment means each side is treated according to its actual muscle mass. The result is a balanced, symmetric reduction — not a smaller version of the same asymmetry.

Masseter Botox Timeline — What to Expect
Weeks 2–4: The muscle begins to relax. Bruxism patients often notice reduced jaw tension and morning headaches improving first.
Weeks 6–8: Visible slimming becomes apparent as the masseter reduces in bulk. The lower face appears narrower.
Months 4–6: Full result visible. Facial shape shifted. Maintained with treatment every 4–6 months; interval extends with regular use.
Who May Benefit From Masseter Botox?
Masseter Botox may be appropriate if you experience jaw tension, teeth grinding, or want a slimmer lower face without surgery.
You may be a candidate if you:
- Grind your teeth or clench your jaw (bruxism)
- Experience jaw pain, tension headaches, or TMJ discomfort
- Want a slimmer, more contoured jawline

- Prefer a non-surgical approach to facial reshaping
Every treatment begins with a physician consultation to assess your jaw anatomy and create a personalized plan.
