No matter how many times you see it in a magazine, or splashed across a television ad, you never really trust a beauty product until you've tried it. The next best thing is a referral. The power of referral is the most important selling tool in beauty because if it worked for one person, it's more likely to work for you. As beauty fiends ourselves, the writers of The Fashion Spot have come together to tell you our must-have, can't-live-without products that reside in our makeup and beauty kits. With picks ranging from favorite foundations to holy grail moisturizers, take a look at our list and maybe you'll find your next favorite product.
