i think 90% of women who wear foundation don't need it. all you need is a good moisturiser and a good concealer. dab concealer on the 'trouble' spots, and blend well. maybe add some powder if necessary. looks way better than foundation, and it's way better for your skin.
i don't like the airbrushed, fake look of foundation anyway. that and i can't stand the feel of it on my face.
