I just wrapped it and got it once, and it felt a little stiff. After 2 weeks, there was a noticeable change. My jaw line became smooth. It's been about 3 months now, but I continued to use it while eating, so it seems to have come back, but I still have stiffness only on the right side.. If I get a little tired or eat something tough... I'm scared, so it comes back again. I don’t think that’s right ㅜㅜ
