Lucky Magazine has a list of the makeup used in making Twilight.
Apparently both Robert Pattinson and Kristen Stewart were covered in Shiseido Ultimate Sun Protection Cream SPF 55, (According to a statement elsewhere, Cat say the cool new Hollywood kids are all going pale rather than orange!) and then caked with Mac Blot Powder/Pressed in Light (again, pale, of course).
Cat Marnell states that the daily rain gave them issues. “Then Van Phue discovered that SK-II AirTouch Makeup and Smashbox Limitless Lash Waterproof Mascara in Black were streakproof, and added them into the mix.”

She also tells that “both wore Benefit Silky Finish Lipstick: Kristen’s shade was Good to Go; Robert’s was–wait for it–Ms. Behavin.”

Another reveal from Ms. Cal is that on the set, Twilight stylists use Redken mousse to make our dear Rob’s hair into Edward’s hair.
