18 Classic Beauty Products Our Editors Will Buy Over and Over

"My mom first showed me this magical concealer ($70) when I was a teenager, and at first I chastised her for spending that much money on a beauty product. Then I used it. The formula is buttery and thick; a little goes a long way, and it's so easy to throw into your bag for quick touch-ups. Now I can't go back to just any old concealer; nothing else comes close. This is the one makeup product I know I'll wear forever." — India Yaffe, editorial assistant, Shop
