I got chin botox twice, two months apart. The first time was with the domestic product, and the second time was with the German product, but I didn't feel much of an effect ㅠ Especially, the first one didn't have any effect at all , and when I got the German product, people around me said I looked like I lost weight (even though they didn't know I got it), so I was surprised, but it didn't get dramatically smaller ㅠ I have a big bone structure to begin with... I'm thinking about getting it again!
