I bought it last summer ('08) and never unpacked it until 5 days ago. In these 5 days, I have noticed an excellent improvement! My "jowls" are at least 40% smaller, my overall face seems tighter, the smallest lines I can't even see, and generally speaking, it's great!
I have not noticed the same firming on my neck, so I am going to spend 3 minutes on my neck alone and see what happens. It's not the moisturizer, since I am using my same one - it's the wand. I am going to try it on cellulite and see what happens.
