What is Masseter Botox?
Masseter Botox is a refined, non-surgical treatment that involves precise injections of botulinum toxin type A into the masseter muscles along the jawline, responsible for chewing and clenching.
By temporarily relaxing these muscles, the treatment softens their activity, reduces tension, and gradually refines the lower face. The result is a smoother, more contoured jawline and relief from discomfort associated with jaw tightness or grinding.
Masseter Botox is best suited for those who:
- Experience jaw tension, clenching, or bruxism (teeth grinding) that causes discomfort or muscle fatigue.
- Notice a wider or square jawline caused by enlarged masseter muscles and desire a more slim, V-shaped contour.
- Have facial asymmetry linked to uneven muscle activity.
- Prefer a non-surgical solution to achieve a more balanced and refined lower face.

FAQs
How does Masseter Botox slim the jawline?
Masseter Botox slims the jawline by reducing the activity and size of the masseter muscles. As these powerful jaw muscles shrink over time, the lower face appears narrower and more contoured, transforming a square jaw into a softer, more refined profile without surgery.
How quickly will I see results from Masseter Botox?
Most patients begin noticing reduced jaw tension and subtle jawline slimming within 2 weeks, with full cosmetic and therapeutic effects developing by 4 to 6 weeks post-treatment. These results continue to improve gradually during this period.
How long do the effects of Masseter Botox last?
The slimming and therapeutic effects of Masseter Botox usually become visible within 2 weeks and last about 3–6 months. With continued treatments, the muscles can become progressively smaller, leading to longer-lasting jawline contouring and sustained relief from teeth grinding and jaw tension.
Is the treatment painful?
No, Masseter Botox is generally well-tolerated and considered minimally painful, as the injections use very fine needles and take only a few minutes. Most patients describe the sensation as a slight pinch or pressure, and clinics often apply a numbing cream to maximize comfort during the procedure.
Is Masseter Botox safe?
Masseter Botox is considered a very safe, well-tolerated treatment when performed by experienced medical professionals. Side effects are typically mild, such as temporary swelling or redness at the injection site, and serious complications are rare. Choosing a GMC-registered doctor ensures the safest, most effective results.
