Thanks for the insight, James. In response to the "Who are you guys kidding?" comment—I'm not sure who that's directed at, but as I'm not a scientist or MD, I have no inside knowledge of how these machines work. I'm just a member of the "gullible" public that you're referring to, giving my two cents on the free trial I was offered by a medispa here in Toronto.

I get what you are saying about doing your research on this stuff, but as you can imagine, it's incredibly difficult to find unbiased voices in the cosmetic enhancements field.... and most women (including me!) would have absolutely zero idea of what "optical spectroscopy" even means! :-)
