I love the dewey look too, a la Jennifer Lopez. She always has that healthy glow. The thing with her is she, I know she uses the DIOR pray foundation. I think Studio Powder Plus works best because it will absorb the best into oil skin if that happens to be your skin type What I so is I apply the Studio Fix Liquid with a foundation brush. Then I take a big powder brush and set it with the Studio Fix Powder plus. Then you can highlight key parts of your face with the MAC Irridescent Powder in Golden ( highlight like your cheeks, forehead, chin and nose) Not a lot just enough. Then Apply like a bit of highlight in your inner tear duct making your eyes look brighter and the whites of your eyes whiter. And a simple lipgloss will set it off. The object is to look....EFFORTLESS.....SWEETFACED....AND AWAKE.

And dont forget to prime your face.
