Seen by whom? You could start by asking them. Conceptions of sexual and aesthetic beauty vary among people and cultures, and are often just different expressions of the same value. For example, the love of creamy light skin and the love of chocolatey dark skin share a common value in the appearance of smooth, pristine flawlessness, which is embodied in the best examples of each.
There's a lot of quazi-political hubbub going around about what "society thinks," but it seems most of it is based in the content of drugstore gossip magazines and the like, which are constructed to appeal to the lowest common denominator to make money, and aren't truly representative of what is most valued by the influential members of a society, let alone representative of what is truly valuable. I think we should be careful not to take those things too seriously.
