Is airbrushing unethical in advertising?

At present, exposure to heavily airbrushed images of people in advertising is inevitable. The idea that these unrealistic depictions have a negative affect on the way people view themselves is one that has been around for some time, particularly with regards to women. Companies in recent years have begun to produce campaigns which focus on "real women." By appealing to "real women" with real flaws, (the entire un-airbrushed population) they are attracting a large audience... to come and buy there ethical products. Cause being ethical is fashionable? And makes you feel good inside!

Here is a Dove Evolution advert which shows exactly what goes on behind the scenes on a beauty shoot.
