Beauty fads come and go, and all most of those products do is clutter up your cosmetics drawer. But when we hear of a so-called miracle product, it's tempting to find any excuse to head to the mall, drugstore or online to snap it up. Whether it treats acne, minimizes pores, reduces the signs of aging or makes another claim, the truth is, most of these products just don't measure up to the hype. Here are a few "must-haves" that you can skip. With all its celebrity endorsements, you might think Proactiv products are the be-all, end-all for treating acne. But for many users, it may have cleared up some zits while drying out their faces in the process. TotalBeauty.com reviews were largely negative for the darling of the infomercial. Reviewers claimed that the product dried out their faces, some to the point of almost burning it. Basically, it boils down to skin type - it seems those with super-oily skin had the best results, while people who only suffered from the occasional breakout really got burnt by the product's claims.
