This will probably change, but favorite 3 right now:
1. Nyx Matte Setting Spray
2. Smashbox Brow Tech & Cream Eyeliner Palette
3. Extra Virgin Minerals Foundation Brush
Although if I had to pick only 3 products that I could wear, it would probably be a concealer, lipstick (Stila Color Balm - definitely #4 for the list if I kept going), and mascara.
*Oh, and by "best ever" I mean "most life-changing when I discovered them." Wow.
