The reviews seemed to be limited to a few product lines; I had no sense that exhaustive testing had taken place. Funny, the authors seemed to favor the products of the guest reviewers! Advice contradicted itself; for example, on one page it said to apply SPF before moisturizer, while on the next it said the exact opposite.The $50 of free samples I'd value at closer to $10 and not the stuff you'd be wanting to try. The whole effort screams product promotion and not legitimate recommendations.
