I think the point of the add is not to accept yourself neccesarily, but to realize that the models we see in magazines and commercials are genetic oddities. And no matter how much firming lotion you use, you'll never look like them. These women are all in decent shape for normal people, AND have good looking firm legs.
It's sort of saying, why bother showing models for this skin product, when you all know that this models legs look this because of her genetics, and not any product. But with more normal sized women, their still attractive legs are achievable for most of us. Or atleast one pair of those legs will be (they show a variety of heatlhy body types, this is NOT about obesity or even weight). Maybe they look that way without any help of the product, but I guess it's just saying "if she can have legs like this, so can you".
No amount of body cream will give me the legs of a model. No amount of working out or dieting will give me those legs. Putting the image of non model bodies out there so boldly also helps us be more accepting of different shapes... just because we sit it more in a medium that is celebratory. (how media influences our perception)
Anyway, I also agree that for clothes, I do like to see it on a model body. I'm buying the clothes, not the body in that case (where as a body firming lotion, you are in a sense buying the body that is being advertised, and with a traditional model selling body lotion, it makes it look like a scam subconciously, cause you know that the model looks like that genetically).
I think i've said the same thing over and over again.
Anyway, I like the adds. It's a good idea to remind people that the traditional models body is not the ONLY type of body worth seeing.
