I know this is an old thread, but I am just cruising the site. Now I hate to be a kill joy, but here goes.
I bought the bare minerals foundation powder, then did some research. (go me!) One thing was negative was the fact you breath in the fine powdery minerals. While they may be natural they are not meant to be inhaled. It is an irritant in the lungs, causing bronchitis and other respiratory ailments.
I have to wear make up for my job and try not to look like a circus clown, the bare minerals gives a very natural glow. Almost sun kissed look, well for me anyway I have med dark skin. I try not to breath in while applying.
