advertising raising the standards

All advertisements have people in them that society would define as good looking. I mean, if you are trying to sell a women's cosmetic product and the woman in the commerial is not one of the most beautiful women you have seen then then why would you want to buy that product. When the woman is beautiful you think, wow, that product will make me beautiful so i want it. So women will buy the product and then will look more like the model in the advertisement. Then the rest of the women who didn't buy the product are suddenly less beautiful. It is not the advertisements that raise the standard of what beautiful is... it is the competition between women. Just like men try to get more muscular, women try to become more beautiful. Advertisements don't define beauty, society does. Advertisements are only a refelction of what society sees as beautiful.
