Been thinking about trying this stuff, but at $150 a pop..wanted to ask you ladies first. Plus when I was checking it out at Macys yesterday, I discovered there are a few different kinds. The original, an eye, a hand, and some thermal kind. So, if you please...experiences, stories? Was hoping to help crows feet, smile lines, I get botox for my frown and forehead. Any insight is greatly appreciated, thanks!
