Masseter (Square Jaw) Botox in Nampo, Busan
Slims a square jaw by relaxing an overdeveloped chewing muscle, for a softer V-line over weeks.
What is Masseter (Square Jaw) Botox?
Square-jaw Botox is one of the most popular Korean face-slimming treatments.
How it works
Toxin is injected into the masseter muscle. As the muscle relaxes and shrinks with less use, the lower face looks slimmer. The doctor checks muscle size by touch first.
Korean name: 사각턱 보톡스
