I got a contour injection around June and I didn't see the effect, so I got contour 2 + chin botox elsewhere, but my chin is short and round, so I tend to have a double chin. It came and I ended up exhaling.. If you have a face shape like me, worry more, honestly, you might think it's easy because it's petite, but this is a kind of treatment and it has side effects ㅠㅠ I was really stressed because of my sagging.
