Okay, for the blush the higher you apply the blush the younger you're going to look. So the trick is just kind of getting, staying with the apple of the cheek is, it's the hard bone. Her's is right here. Starting, and in circular motions kind of work your way back and blend it. For the dewy look just put some highlighter on top of the cheek bone, like so, and blend it down. Streak it through the blush. For a nighttime look, if she wanted to make a more contour look she could do that by using bronzer. And putting the bronzer in the hollows of her cheeks. Do you like that, without feeling too silly? Her's would be right there and just kind of take it and work your way up. I would just do that for a nighttime look otherwise it will look too dramatic. Also, take a little right where your face would naturally get too much sun: your forehead, cheekbones, bridge of your nose, your chin.
