What is square jaw?

A wide lower face from a prominent jaw muscle or bone. Common causes include masseter muscle bulk or jaw bone shape. Because several factors are often involved at once, Gangnam clinics usually begin with a skin or facial analysis and then combine treatments rather than relying on a single procedure.

Treatments for square jaw in Gangnam

How doctors build a plan

A typical plan starts with the least invasive option that matches the cause, then adds stronger treatments if needed. Many visitors combine a device treatment with an injectable on the same day, but your doctor should confirm what can be safely combined and how far apart sessions should be.
