Propaganda In Advertising

In this commercial, as well as others made by Proactiv, celebrities like Justin Beiber are used to sell the idea that you can be as attractive as these people if you were to use their product.  I recall when Proactiv first aired their campaigns, they were using doctors and experts to sell their product.  Suggesting that since they were licensed practitioners, they had to know what they were talking about, and we should accept their opinions as facts. The first celebrity that I saw pushing Proactiv was Vanessa Williams. Since then I've seen P. Diddy, Lindsay Lohen, yikes! At first the product was aimed at adults, now it seems they are targeting the younger demographics
