Tightlining is a great technique that makes eyes pop like there's no tomorrow. Many women find it difficult at first but if you're new to tightlining just take your time and be patient because I promise it does get easier. Also, you don't need a special tightlining product, just make sure to use a liner that works with your eyes. I personally love the Buxom Lashliner in Leatherette. It's is a gel eyeliner applied with any small liner brush and the color lasts all day. I have beyond super sensitive eyes and have never had a problem :) 1. Using clean fingers, gently lift your lashes upward (this step is only necessary if you find it easier to tightline). You'll see tiny gaps between your lash hairs, which you'll be filling in with eye liner. 2. Using either a gel or pencil eye liner, lightly dab the eye liner in between each individual lash (as close to the root as possible), to fill in your lash line and make it look fuller. Start at the the inner and work to the outer corner of your eye. 3. To intensify the look, tightline your bottom lash line as well. It's the same concept as the top, but you'll be filling in the space between your lower lashes.
