Usually fake tans, the kind in a bottle that you spread/spray all over your body - some of them do this on their face as well, others find a matching foundation (and I do mean matching; they're very particular!).
One thing, rebekah, is that they usually fake tan/paint in their natural lipline as well, and the white lipstick goes on top in a smaller, more "kissy face" sort of shape. Kind of like Clara Bow, LOL. The example pic you posted shows the lips quite clearly, if you're planning to copy that part. Also, I can't tell if it's just the bad lighting in your photos, but the edges of your white eye make-up look blended in and blurry - Ganguro girls usually like the lines sharp and contrast obvious.
Of course, this is your interpretation of the look, and if you like your version better, go for it.
