I have been using Bare Escentuals i.d. bareMinerals for over 7 years now. I can't find anything that comes close coverage wise, but still leaves a natural look. I really like how you can layer on more where needed, like to cover acne scars or dark shadows on the face. It also has a nice opalescent shimmer to it, to distract from imperfections and give an overall glow. Works best on normal to oily skin, can get flakey on dry skin. The only downside is if you knock over the container...like I have...you end up with loosing a lot of product and staining your suitcase (navy blue with beige foundation all over it...sweeet). I like how some of the new mineral lines from other Brands have a built in shaver/grater to avoid this type of disaster.
I have yet to try the Matte version of the bareMinerals, but I will be sure to post as soon as I do.
