When it comes to red lipstick, you sure can’t beat MAC’s Ruby Woo. Over the years (over 20 since it launched, to be exact), the bullet lipstick has reached icon status, with everybody from Rihanna to Taylor Swift claiming to be big fans. In fact, it’s such a hit that these days, one sells every eight seconds: an impressive feat in a world where red lipsticks are a dime a dozen.
