Botox isn't just for smoothing wrinkles; it’s also a popular treatment for jaw slimming. By targeting the masseter muscles, Botox can reduce the appearance of a wide or square jawline, giving you a more contoured and youthful look.
What Is Jaw Slimming Botox?
Jaw slimming Botox involves injecting botulinum toxin into the masseter muscles, which are the main muscles used for chewing. This non-surgical procedure relaxes the muscles, gradually slimming the lower face and creating a natural V-shape.
Clinical evidence supports the effectiveness of this treatment, showing a measurable reduction in masseter muscle size and improved facial contours.
How Does Botox for Jaw Slimming Work?
Botox works by blocking nerve signals to the masseter muscles, preventing them from contracting excessively. Over time, the muscles shrink slightly, softening the jawline and producing a slimmer, more balanced appearance.
Studies confirm that repeated Botox injections safely reduce masseter thickness, resulting in noticeable aesthetic improvement without surgery.
