Gradual Refinement
What Is Jawline Slimming?
Jawline slimming is a non-surgical treatment that targets the masseter muscles - the strong chewing muscles at the sides of the jaw.
​
When these muscles are enlarged or overactive, they can create a wider, heavier, or more square lower-face shape.
​
Anti-wrinkle injections relax the masseter muscles, reducing their activity and allowing the lower face to appear softer and slimmer over time.
