Bare escentauls are fab on my slightly oily skin.
It takes seconds to apply, a quick dab with my finger to cover any blemishes and under eye bags, then a few swooshes with the full coverage brushes - a swoosh of blush, a swoosh of sheer radiance and a dab on eye brow bone quick swoosh to blend it all, then lippy and mascara and I'm done.
It is important to get the right application brush - I use the full coverage one, but the medium coverage would be good for people with good skins.
I really like the way the blemishes cover over so easily, without the need for a concealer. You can also use the blush pigments under a colourless lip balm for matching lippy (if you are that way inclined.
A little goes a very very long way - I am still on my first tub of foundation which I bought in the US last July and have used it daily since then.
