Botox for Facial Slimming in Busan, Korea Slim a wide, square jaw by relaxing the masseter muscle, from ₩15,000
If your face looks wide at the jaw because of a strong chewing muscle, Botox can soften that line over the following weeks. At JRYN Seomyeon, the doctor first checks whether muscle is really the cause , then confirms the brand and dose with you.

How does Botox slim the face?
Facial slimming Botox is injected into the masseter, the chewing muscle at the angle of the jaw. When that muscle is large, it pushes the lower face outward and makes it look square. Botox relaxes the muscle, and as it is used less it gradually becomes smaller, so the jawline looks softer and the face more oval. The change builds over several weeks rather than overnight.
At JRYN Seomyeon, square-jaw Botox is ₩15,000 with Korean toxin (Newlux) , ₩35,000 with Coretox , ₩90,000 with Dysport and ₩139,000 with Allergan 50U . The doctor confirms the brand, dose and total before injecting.
