Mascara

In the beauty world, the old adage that everything old is new again often rings true. Take intensely defined lower lashes for instance, once seen adorning the eyes of stars like Liza Minnelli and Twiggy. Now they're making a comeback. Recently, Natalie Portman wore full lashes on both the top and bottom lashes, while Chloë Sevigny just opted for a softer, Kewpie doll-like take on the trend. Cynthia Rowley even featured heavy-on-the-bottom eyelashes at her Spring 2011 runway show.

Accentuating your lower lashes is a chic way to open up the eyes, frame bangs, and add instant interest to a beauty look. It's also the perfect way to bring a bit of the runway (Phillip Lim, Yves Saint Laurent, and Miu Miu have all featured similar takes on the look in the past) to your everyday style.

In the world of colored mascaras, blue, brown, and plum get all the credit. Green, however, is like the cousin who people always forget to invite to family dinner. Sure, blue makes your eyes brighter, and brown and plum give definition without being as harsh as black, but certainly green does some good as well, right? Otherwise, why would it exist? To see how green mascara looks on, and read about what it's designed to do, just keep reading.

Since Latisse (which I tried) came out, the market seems to have exploded with products designed to make your lashes longer, darker, thicker, and more conditioned. Many of these products are extremely expensive, and even those that aren't as outrageous in cost are still more pricey than a good mascara.

There are plenty of ways, however, to get your lashes in tip-top shape without shelling out egregious sums. So to see how you can get the doe-eyed look without blowing all your dough, just keep reading.

Cover Girl LashBlast is one of the most popular mascaras on the market, and it's definitely one of Team Bella's favorites. That's why I think it's cool that Wired broke down all the ingredients in the LashBlast Luxe ($8) formula and explained them in layman's terms.

We rarely think about beauty products on the chemical level, even though we're generally very picky about formulations, so it's nice to see an in-depth look at why and how something like mascara works. The piece dispels the old "bat poop in mascara" myth by explaining that guanine (not to be confused with guano) used to be a key ingredient in most mascaras. It also highlights the magnetic molecules used to get your mascara to adhere to your lashes and keep it from separating in the tube. And one more fun fact: you also shouldn't wear mascara if you're having an MRI, because there's so much iron oxide in the stuff that it throws off the imaging apparatus.

Applying eyeliner can be tricky for even the most adept of us, and that's why I turned to celebrity makeup artist Brett Freedman for guidance.
