I use CO and olive oil and occasionally, my skin feels kind of dry/tight afterwards, so I just rub a couple drops of oil between my hands and pat it on. I threw a couple drops of lavender EO in there as well to scent it lightly. Next go round I'm using mint or something, just to see.

I use the same castor oil/olive oil mix with my mineral foundation (aromaleigh) and it works awesome-I've used that blend for several months, and it doesn't cause breakouts, smooths on nice and even, and doesn't leave my skin feeling dry. Makes it last longer as well. Never tried it with BE or anything-bareminerals made me break out something fierce.
