I have really been nuts over mineral makeup lately. I keep seeing more and more of it in the stores and I keep buying it! Recently I tried another drugstore brand with pretty good results. Jane Mineral Be Pure Makeup is very reasonably priced. I believe I paid around $6 for mine at Osco. Further, unlike some of the other drugstore brands, this one is talc free. It is also oil free, wax free, and fragrance free. I could not verify though whether it contains bismuth. An ingredient list does not seem to be available online. [update: Based on search results that were not available when I first published this, apparently it does contain bismuth]
I purchased the fair shade and was quite happy with its coverage. Tapping it on with a kabuki brush, I found that it covered a couple of my light melasma spots better than the other drugstore brands I have tried. As with most mineral powder makeup, tapping it on helps it cover better, while brushing it on makes it work more like a regular powder. As for staying power, it was OK. It isn't going to cover or last the way Jane Iredale or Bare Essentuals do, but I am finding that when it comes to mineral makeup, you often get what you pay for. With that in mind, Jane seems to be a very good value for the price.
Jane Be Pure Minerals are packaged in a jar with a sponge type applicator. I wasn't crazy about the sponge and highly recommend the purchase of a kabuki brush for putting on mineral makeup. If you want a quality cheap one and live near a CVS pharmacy, take a look at the essence of beauty brush. That is a great line of inexpensive, good value brushes and I have been happy with their kabuki brush. Also, the jar is a bit small for dipping a brush in. I would prefer to see a design where the jar is a bit larger and there is a plastic shaker screen for rubbing a brush on. But aside from nit picking a few packaging decisions, I really like this mineral powder as an inexpensive, good value product.
Update: Jane is getting very hard to find and I suspect that it has been discontinued. for other mineral makeup options, see the comparison shopping link below.
