the mineralize skinfinish natural isn't a foundation, it's a sheer to medium coverage powder. it contains 77 minerals, so unless you are allergic to any of them, you could give it a try. it won't, however, give you alot of coverage if that is what you are looking for.
if you are wanting a mineral foundation, there is a loose powder mineral foundation coming out on april 24th. it is medium to full coverage, and also has 77 minerals. it also has spf, which the msf natural does not. it contains wheat germ, which conditions the skin, making it great for dry skin (i've heard that BE can show flakes on dry skin), and is also soothing for sensitive skin.
depending on what you are looking for, give these a try. hth!
