Liquid eyeliner is a cosmetic product designed to line the eyes and give them a more dramatic, noticeable appearance. Choosing the best liquid eyeliner is largely a matter of personal preference, depending on your preferred shade. To begin choosing an eyeliner, first determine if you need it to be waterproof or not.
Liquid eyeliner works well in waterproof forms, though it will need to be removed with makeup remover. In addition, you will need to choose what color eyeliner you want. The most popular eyeliner colors are black and brown, as these tend to look most natural. Liquid eyeliners come in all different colors, however, and the benefit to using a liquid eyeliner is that the colors tend to appear much bolder, sharper, and brighter on the eyes than those from an eyeliner pencil. Those with lighter eyes might be more likely to choose a brown or charcoal eyeliner, while those with darker eyes might choose a black eyeliner; however, when applied properly, any color can look great.
Most people who use eyeliner have more than one shade or type for different occasions. Eyeliner in liquid form gives a much darker line than eyeliner in pencil or eyeshadow form, so keep that in mind when choosing a liquid eyeliner. Also, keep in mind that it is not possible to "blend" an eyeliner in liquid form with eyeshadows on the eye, as many people like to do. Liquid eyeliners nearly always come with an included applicator brush, so it is not necessary to purchase a separate one.
Liquid eyeliner is often described as the most difficult type of eyeliner to apply. With practice, though, it can be applied to the eye in one smooth line, without needing to pull on the eyelid to draw the line, as with a pencil eyeliner. Constant pulling on the eyes can lead to loosening of the skin and wrinkling. Liquid eyeliners are also better able to fill in the lash line, and the thickness of the eyeliner line can be much better controlled with a liquid than pencil. In general, a thicker line will give a more dramatic appearance to the eyes than a thinner line.
Choosing the best liquid eyeliner may take some trial and error. It may be helpful to read reviews of different eyeliners online, to learn if it is truly long-lasting or can be removed easily. It is also important to choose an eyeliner that does not irritate your eyes; if it causes redness or pain, immediately stop using the eyeliner, and try a different one. Remember to replace liquid eyeliner every three to four months.
