Instant Human Lab: Beauty

Aired on: June 27, 2008, April 18, 2008

Gretta and Rachael put three brave audience members to the test in the latest edition of "Instant Human Lab," testing products which claim to instantly whiten teeth, lift your butt, and get rid of that underarm flab. Check out the gallery to see the results!

As they test the items, Gretta shares one of her personal favorites for an "instant" younger looking face: Freeze 24-7 & Go Instant Smoother & Brightener. "This is all about smoothing the little lines and brightening up during the day," she says, "basically for tired eyes. But it's on the go so you look fab on the fly!"

Web exclusive! After the show, Gretta demonstrates three more of her favorites!
