You fall head over heels for a $58 BB cream that leaves your skin soft, dewy and impossibly clear -- and you're quite sure there's no other product in the world that will make you look so youthful and radiant. So you do want any beauty-product-obsessed girl on a budget would do: splurge on another bottle and eat ramen for the next week. No matter how much you love a product, it can be hard to justify the price tag, especially on day six of shrink-wrapped noodles. While there truly are some magical beauty products out there for which there is no substitute, plenty of expensive department store beauty products have a drugstore doppelganger that works just as well -- and for a lot less money. We road-tested every popular beauty dupe on the market to find out which high-end beauty products are worth the splurge and which ones you may want to reconsider.
