I've used Bare Escentuals for 2 years. However, it would look great when I put it on but by the end of the day my face looked awful! It never really lasted on me. I then tried using Physician's formula, Neutrogena, Loreal, and Emani mineral foundations and I found those to be less natural and didn't feel the same as BE. I later found Everyday Minerals intense and won't go back to any other mineral makeup. It's a lot cheaper than BE, just as pure, contains only 4 different ingredients, and offers more coverage since I purchase the intense version. The containers are also a lot cuter! you can even get free samples online!
At one point, I ran out of mineral make up so I had to go back to using standard MAC liquid foundation for a day ( I had some left over). I felt like I was putting a bunch of artificial chemicals on my face and it felt too heavy. My face felt dirty. It had good coverage, but it just felt different. Now I dont think I can ever go back to anything but mineral foundation. The only non-mineral make up that I do use is anything that goes on my eyes or lips.
