Real Beauty, and getting old

Find the differences. I First spotted this tic-tac-toe ad on a street billboard in Copenhagen, and then in major media publications in the U.S. (before hitting the major markets, the agency behind it probably wanted to test the water with the Nordics first, recognizing their penchant for bear skin and resistance to pain.) What is it selling? Diesel jeans, of course, or rather, Diesel genes. A culmination of desire embedded in fabric. A bored adolescent (of unknown gender, but probably a male) is getting flogged by two half naked women, all in the name of a fun game of tic-tac-toe. One of the women has already taken her turn in being whipped, and lost a round of this wonderful game. The players seem happy to inflict pain upon themselves, and the colors in the background give the entire scene a hellish look. The message: buy diesel jeans and you too can blur the lines between pain and gain; when you've got it all, all you need is a little pain to spice things up.
The second ad, in contrast, started flooding the media a few weeks ago as part of Dove's campaign for real beauty. Real women have real curves, they tell us, with the hope to sell more soap. For the longest time ads have shown us the 'unreal', building up the economy of desire. It's time for a change, and Dove has commissioned real women, to show real beauty. These two ads are not new. The same moves have been pursued before. Benetton is famous for incorporating the uncanny into its marketing campaign (including images of children with Down syndrome, and dying HIV/AIDS patients. The campaign for milk has gone a transition in the opposite direction (from being a 'milk does the body good' necessity to being an object of 'got milk' desire, bordering profanity when drawing mustaches on the likes of glitterati like Brooke Shields and by alluding to milk's physical similarity to other bodily fluids). But what I find striking about these two campaigns is the extreme they go to in the segregation of their audiences, on one hand, but the reliance on the same psychological move of identification on the other hand. The Diesel ad caters to the young and frivolous. The Dove ad caters to 'real' people. It seems as if there is nothing in common between these two crowds, and yet, the entire campaign (like most marketing campaigns) is built on the viewer identifying with the object in the ad.
So this is the question. When in the cocoon of life do the young and frivolous become real? When does the beautiful butterfly become a real larva once again?
