Temptu Pro Setting PowderOne of the most important product in a makeup artists' bag? A super-sheer, yet buildable, finishing powder — and Hollis swears that this pick is the absolute best. "If you're using anything on your face that's liquid or creamy, set it with this powder —it has the silkiest-ever finish, and it'll last through anything," he says.
