I've had expression lines since I was 7 and they were getting BAD. Its been two months exactly today and I have movement again, and I'm going again tonight so I have no movement at all. I am hoping after a year of going every three months I can go to every six months as the muscles wont be wanting to do what they want to do now. The movement I have is nothing compared to what I had two months ago though, before pics really help to see exactly what it does. I hold so much tension in my forehead that I had daily headaches. God I love it. I was reluctant to do it, but it's done in 30 seconds and I'm out of there. Easiest thing ever.
