All In One Natural Mineral Face Powder
($19.95, comes with stick foundation)
If you hesitate to wear foundation because it takes too much time or effort, or if you have sensitive or breakout-prone skin that reacts to most liquid or cream makeup, loose mineral powders like this one from Jerome Alexander are a great alternative. In the loose mineral makeup category, there are several brands to choose from, and they all have roughly the same ingredients in a slightly different order:

Bare Minerals from Bare Escentuals: mica, iron oxides, micronized titanium dioxide, bismuth oxychloride
Jerome Alexander: mica, bismuth oxychloride, titanium dioxide and iron oxides
La Bella Donna: micronized titanium dioxide, bismuth oxychloride, zinc oxide, iron oxide
Youngblood: titanium dioxide, bismuth oxychloride, mica, iron oxides

For most people, these are ingredients that don't clog pores or irritate sensitive skin. I've tried several brands myself, including Youngblood, La Bella Donna, Origins, and Philosophy, and I like Jerome Alexander the best. It has very little shine, does not cake or settle into fine lines, and I think it feels the lightest on my skin. Surprisingly, I also found the best color match for me with JA - and it comes in only three colors (light, medium and dark). I can apply it with a loose powder brush for soft, light to medium coverage, and use the enclosed sponge to add a little extra to areas that need more attention. All in all, this is a great product at a great price.

You can find Jerome Alexander products online on the Home Shopping Network. You can also find this foundation for around $10 on occasion at firstauction.com, which is where I got mine.
