Bare Minerals is a makeup line that I have seen advertised a number of times on television. On their website, they say:
This extraordinary beauty innovation is made of only crushed minerals from the earth, free of preservatives, talc, oil, fragrance and other potential skin irritants. It provides feather-light, adjustable coverage for all skin types and conditions with the look and feel of beautiful, bare skin.
They also list the only 5 ingredients they use in the FAQ section of their site. It's nice to see a company being clear about what they are putting in the things WE use.
I personally haven't tried it, but it seems interesting. A lot of foundations tend to be cakey and thick. It is on the pricey side, but if you use makeup on a regular basis, it seems to be a good investment.
