I know a few people who feel that the beauty industry is silly or that women who wear make-up should be more natural, and I always find this amusing as I know first hand how powerful it is. I've seen many husbands and boyfriends change their minds on the topic once they've seen how their wife or girlfriend has been transformed. Just take a look at any make-over show on TV and you'll know what I'm saying.
There's nothing wrong with being barefaced, however, in general how we groom ourselves does say a lot about who we are and how we feel about ourselves. I don't care what anyone says, the moment any man or woman stops caring about their looks or taking care of themselves, they've given up. Period.
I found these two amazing videos done by the beautiful Make-up Artist Lisa Eldridge. Madeleine Marsh wrote a book about the history of make-up from the Victorian Era straight through to the 1970's. Once you see the history behind it, and how it's tied into everything that we do, and how the trends are directly linked to what's going on in the world (for example war-time, baby-boomers) you'll have a whole new appriciation on the topic.
