There are many ways to apply eyeliner but the things to remember are you need to start from inner or middle of your eyelashes and should brush it outward. You also need a firm hand to make smooth and unbroken lines as well. Here are few tips that will help you apply the perfect eyeliner.
Whenever you are going to apply eyeliner, make sure that your eyes are clean or try to clean your eyes before applying eyeliner.
Take the eyeliner and then start applying eyeliner with the inner line of the eyelashes and after doing this wiggle the liner inside the lashes. This will make your eyelashes look thick and dense.
I personally add a touch of mascara.
In last step, watch your eyes in a mirror to ensure that there are no dissimilarities.
