I actually tried Sheer Cover! Unfortunately I didnt have a great experience...it just seemed VERY chalky...and I used it a lot. It was only with the foundation/powder/mineral cover stuff that sucked for me, I loved everything else! Except the brush....I still use it if or blush only because I dont have any other face brush, but it sheds tremendously and isnt very soft. But I absolutely LOVED the moistuizer, face wash, and concealer! They were just awesome...the moisturizer was great, and I often mixed it with the mineral powder to make a tinted moisturizer. But by far my favorite was the concealer. It was two shades, lasted all damn day on me, and matched my skin perfectly. I will sorely miss it! Also, the refillable powder/brush thing is horrible...You cant really control the release of the powder so it is very messy.
I think one of the main reasons I didnt like the makeup was because i *think* the shade was a little light. But I could see it settle into my pores and build up tons no matter how much or how little I applied. Also their copy of "mineral veil" sucked...seemed like normal translucent face powder to me. I like the system though overall, a very good idea. They say to wash then moisturize your face til it absorbs. Then, apply concealer anywhere you need it. Then buff the foundation on and follow with the finishing stuff. They also say that you can mix the moisturizer with the foundation...wait, I already mentioned that! Rambling, sorry. Anyway like I said the concept was awesome and so were all the products BESIDES the foundation. Sorry to say that my first experience with mineral makeup was a bad one but I hope soon to try Bare Minerals. Actually I'm more excited to try aromaleigh products. They have very affordable samples you can order, contain no bismuth and contain small amounts of non glittery mica...not too expensive and the site is very friendly. I'll try them out before I try Bare Minerals I think (the final frontier lol!). Hope this helped some!
