I'm an announcer and weather caster trainee! (I have YouTube experience) I'm thin and have no double chin, but I thought my jawline looked blurry in front of the camera. Then I saw Hwanyeon Go00's YouTube channel and went to get it done right away since it was close to my house! I got it domestically instead of imported and it was cheap! It's not as dramatic as Hwanyeon Yeocheolbun's effects, but I'm satisfied :)
