In 1976, sisters Jean and Jane Ford flipped a coin – heads they opened a deli, tails they opened a makeup store. It landed on tails, so they set up shop in San Francisco and launched whimsical cosmetics brand Benefit. We’ve handpicked a few of its products and it's safe to say that the POREfessional primer and They’re Real! mascara are two of our faves. Check out the brand’s high-beam highlighter too – it’s won awards, don’t you know.
