What Products Do We Discuss?
It depends on what you ask about, but pretty much anything you put on your body is fair game.

• What you can really expect the product to do (or not do)
• How the product does what it does.
• How the product is made.
• How the product is (or isn't) different from similar products.
• What the advertising behind the products really mean.
