ok, so i used to buy bare minerals make up in the states when i was still there and recently self ridges just started selling it in london. i've always liked it, but don't think it's particularly better than prescriptives brand foundation/concealer and stuff...but it does the job and looks great in pictures.
my favorite is their blush in 'true' and the mineral veil. the spf foundation powder and the different shades aren't the greatest but i do use them. also, if you're not careful with the primer it can look caked on...but i'm sure you make sure to remove your make up better than i do sometimes. i've found that kabuki brushes leave a better finish.
