"Great Lash is horrible. Makes me look like I have 3 eyelashes all glopped together. Why does this crappy mascara get such rave reviews?" is what one reader wants to know. Another says, "it gave me stubby lashes and at the end of the day I just couldn't get it off." Still more contribute that "it's like tar," "it did nothing special to my eyelashes, just made them clumpy and stubby looking," and "I never understood the fuss over Great Lash, it gives me raccoon eyes."

The Bottom Line: Just because something's been around for ever doesn't mean it's necessarily great.

The glowing assessments from TV stop short with our real women. "It cleared up some zits, but it dried out my face so badly that it looked like I had burns!" says one reader. A mom chimed in to say "I bought it for my daughters and we ended up going to the dermatologist to get help with the reaction they had to it!" And another review says "I used it as directed, and it just kept breaking me out more, turning my skin red, dry, itchy, and raw. I kept using it while trying to tell myself 'It's just bringing the toxins out of my skin, it will clear up.' But, no." Still, others say that it was effective in the beginning. "At first using this product made my skin slightly dry, but it really reduced my acne. However the more I used it, the less it worked and when I stopped using this cleanser, the acne immediately came back," says one reviewer.

The Bottom Line: Whether or not the product works seems to depend on skin type. Maybe you'll get red, itchy skin, maybe you won't. Either way, you'll still have to contend with another aspect that some reviewers found troubling: having to order it and wait for it to arrive.

Next: Will "Photo Finish," the critical darling from Smashbox, get the green light from our reviewers?

The Hype: Smashbox makeup artists "use this product to create a perfect canvas for foundation application. The silky blend of vitamins and antioxidants does double-duty as a primer and a mattifier, while the unique formula helps to inhibit the destruction of collagen, and fills in fine lines."
