Masseter Botox in London
Masseter Botox is an injectable aesthetic treatment designed to soften a bulky or square jawline and treat Bruxism by relaxing enlarged masseter muscles. By reducing excessive muscle volume in the lower face, this treatment aims to create a slimmer, more refined jaw contour while preserving natural facial structure and expression. It is offered following structured clinical assessment to ensure suitability and balanced aesthetic outcomes. Masseter Botox is intended for subtle facial contouring rather than dramatic cosmetic change, with results that develop gradually and naturally over time.

Masseter Botox Overview
Who Is Suitable For Masseter Botox?
Masseter Botox may be suitable for individuals concerned about a wide, bulky or overly square jawline caused by enlarged jaw muscles. It is considered for those seeking subtle facial slimming, improved lower-face balance or a softer jaw contour without surgery. Suitability is determined following clinical assessment to ensure dosing, injection placement and aesthetic goals align with individual facial anatomy and proportions.
What Results Can I Expect?
Masseter Botox is designed to support gradual reduction in jaw muscle bulk rather than deliver immediate or guaranteed results. Some individuals notice a softer jaw contour and slimmer lower face over several weeks as muscle volume decreases. Results vary between individuals and are temporary, typically lasting several months. The goal is natural-looking facial refinement and improved balance, not an artificial or hollowed appearance.
