I use both the Jane Iredale Pure Pressed Base in Bisque, and the Estee Lauder Lucidity loose powder.
The EL powder is what I use for everyday wear. I usually apply a little concealer under my eyes (dark circles) before applying. I use the puff to apply, then brush off excess with my brush. I love this powder, and think it is wonderful.
Occasionally, for special occasions or if I am traveling (because it's less messy), I use the Jane Iredale Pure Pressed Base. I apply it with a brush. It looks very natural, but definitely provides more of a "foundation" coverage than the EL powder.
Either one of these powders is a winner!
