I've just borrowed this...
Anti-Aging Bible
I know all the products mentioned / rated were tested by women 35+, but my question is how did they select which products to test? Did the companies pay them to test and report about them, or is it the authors real choices. I think what I'm really asking is how much can I trust the list of top products or is it a subtle form of advertising as most of the top products are pricey?
