[Botox] Botox + Contour Injection Review

It's been a little over a month now since I got it hahaha. But my chin is sore, whether I got it wrong or something, and it doesn't go away. It was my first time getting contouring injections, and I was so happy because it felt like I was seeing a whole new world haha. But it doesn't seem to be as effective as when I got it for the first time. Do you know that Botox is effective and lasts a long time? Please share some ㅠㅠㅠㅠ
