I found a social beauty store called <a href="http://www.bloom.com/invite/60668">Bloom.com!</a> Their exclusive Best4You Beauty Finder tells you which beauty products will work best for you. You can buy the products and then interact with other beautynistas.

 

 

 

 

I also disccovered Beautylish, which was founded in February 2010 "with the goal of improving the way that everyone discovers and learns about the beauty products that they use everyday."  At this site, you can interact with other beauty product users; rate and review your favorite products; and view or upload tutorial videos. (You can link Beautylish to your Youtube account!)
