Is there a difference betweeen different mineral make up?

I have heard that Bare Minerals is really great make up. I have been using mineral make up but it is from Mineral Glitters. I also have heard of Sheer Cover.





Are all of these basically the same, or are there real differences in quality?Is there a difference betweeen different mineral make up?
Contrary to popular belief, there is not one lab that produces all mineral makeup. What makes mineral makeup different is the quality of the raw materials along with the recipe. Too much of one ingredient can make the formula too shiny or too heavy, which will make it appear cakey on the skin.Is there a difference betweeen different mineral make up?
