ㅋㅂㅅ did it.. Now they are advertising it as lifetime AS for 2 million won ㅠㅠ But I really regret it.. I was happy that the swelling went down and my chin got slimmer for a few months, so it was pretty... But after a few months, I continued to eat and needed the masticatory muscles, but the nerves were blocked and my jaw muscles became stronger. Since I don't use it, the other masticatory muscles in my cheekbones and temples develop, making my face look even more uglyㅠㅜI'm going crazy... I really shouldn't do this...
