Hi. Have you tried skin b5? It's from Australia. You can get it as a tablet or a powder. It's excellent, I can't recommend it enough.
And if you're looking for a natural foundation that feels great, really light like you haven't got any on but still gives good coverage I'd recommend one from Avon called "Personal Match Smooth Mineral Make-up" You dust it on with a powder brush, it's great, I love it.
