Here's the Dove Real Woman campaign for Japan:

According to this ad, all Japanese women are thin with perfectly flat stomachs. Maybe they are, I don't have a lot of knowledge about Japanese women, but it doesn't seem to reflect differences in women.
For an ad campaign that is supposed to promote real beauty, and these women are supposed to portray that beauty, then why do they need to use Dove's products at all? In theory, they shouldn't require any special products.
