Square Face Shape

Description

A "square face shape," often called a boxy jawline or enlarged jaw, typically results from hypertrophic—or overdeveloped—masseter muscles along the sides of the lower face. This appearance, sometimes described as a "broad jaw" or "box-shaped face," can create a strong, masculine look and make the face appear wider or less balanced. Because the masseter muscles play a key role in chewing, repetitive actions like teeth grinding or habitual clenching can cause them to enlarge over time, leading to visible changes such as a square-edged lower face or even facial asymmetry. Many people seeking a softer, more V-shaped face or "V-line" contour look for solutions to reduce the size of these muscles and achieve a slimmer, more refined jawline. Treatments such as Masseter Botox are increasingly popular in Korea for non-surgical jawline slimming, helping to address both cosmetic concerns and related issues like jaw tension or teeth grinding. Whether you’re searching for "jaw slimming," "masseter reduction," or "square face contouring," understanding the roots of a square face shape is the first step toward finding the right treatment and enhancing your natural beauty.
