Concern > Square jaw

People with a slim face shape due to their angular faces are always the object of envy.

After making some effort with dieting, my more angular face looks even more prominent and bothers me every time I look in the mirror.

Then I learned about square jaw Botox, but since it's unfamiliar, I'm 고민이 되네요.

I was only thinking about wrinkles with Botox, but now there's jawline Botox—how effective is it really, and are there any side effects? I'm just full of questions again.

Is there anyone who has done it?
