In the past, I've relied upon dipping a Q-tip in nail polish remover to clean up the edges, but I discovered something new the other day at my local Ulta store, The Corrector Pen by Essie, ($14). Built like a fine-tip marker, this awesome tool has a firm rounded tip that delivers a steady amount of polish remover so you can get deep into the edges around your nails without removing the polish on the nail itself. It's sold at most manicure salons that sell Essie products and also at Ulta stores, but for some reason it's not available online at Ulta.com. You can, however, order it at Essieshop.com if you don't have an Ulta or a manicure salon near you that carries Essie.
And while you're at it, give Essie's new nail polish Damsel in a Dress ($8) a try. The color looks good on nearly everyone and perfectly complements fall looks.
