I bought a foundation brush but find that, when it comes right down to it, using my fingers gives me the most even and comfortable coverage. I've had instruction in using the brush, but even so, I still prefer the old-fashioned way (smearing it on

).
Something I can't live without right now at age 43 is Anastasia's brow powder duo! Seriously...it's amazing. I've definitely begun losing the outer third of my lashes, and there are graying/missing spots at the inside of the browline. I bought this from Sephora:

I also bought a very dense, small brow brush at Sephora with which I apply the powder. I can't tell you what a difference it makes to have darker brows! And unlike a brow pencil, which always looked unnatural, the brow powder has a very natural look. Great product!
