Shortly after wrinkle creams first came on the market, informative reviews were written about them, for the benefit of potential buyers. Over time the reviews became more and more biased by selling tactics of the vendors.
The first wrinkle cream reviews were of a factual nature. They were written by scientists whose aim was to analyze the properties of the cream, their manufacture, effectiveness and detrimental affects (these were common among early wrinkle creams).
Typically, such reviewers had a full scientific education to post-graduate level, and had worked in similar fields for several years previously. At that time there was much competition for jobs in scientific research fields, so obtaining the appropriately qualified staff was not a problem.
