Transcript for Makeup Wars

A woman's face is a blank canvas until there is makeup. But how much do you really have to spend to get a great look that will last? To find out, we brought three models all the way from mobile, alabama to new york city. There is nothing wrong with your eyes. The grave sisters are identical triplets. We put together three sets of makeup with three wildly different price points. Christie's makeup is unbelievably cheap using pencils shadows and mascara almost all of which costs 99 cents each. Lindssy's is made up of drugstore brands costing $10 or less. Whitney is wearing luxury brand. Foundation $80. Lipstick $60. But is it really worth the investment? Can you tell the difference? Here in central park you would be shocked at how many people couldn't tell which face is the most expensive. They're gorgeous. I'd have to say probably number two?

Finally a tear and then another. All three ladies are wearing water proof mascara. How did unbelievably cheap do? Immediately a see smujing here with the eye liner. So that didn't hold up at all. The drugstore mascara barely smujed. After scrutiny, the con fences is whitney, it is $790 face stayed freshest. Let's get brisket, one pork bone. The lipstick challenge. How will it stand up to juicy ribs basted in barbecue sauce? The unbelievably cheap lips sitting pretty. This time the mid range drugstore brand looked the worst. It's blotchy. The luxury lipstick tied with the unbelievably cheap variety. Up next the hot date challenge. How about 15 minutes in a sticky sauna to simulate a summer night out when the last thing you want is for him to see you sweat. Watch how christie with the cheap makeup starts to perspire.
