Beauty appeal is often used in cosmetic product advertising; it forces the viewer to consider a purchase because the fact that a beautiful man/woman is used indicates that the product has made them that way. Beauty Appeal in advertising can, in some ways, relate to the Promise of benefit advertising technique.
I think this advertisement appeals quite well to it's target audience because, women after a better image are gullible enough to try anything, so, making an advertisement containing Eva Longorea will make every middle aged woman rush to the shops for whatever product it is.
