Eyeliner is a cosmetic product that is used to apply color to the area around the eyes to accentuate and highlight the appearance of the eyes. Eyeliners are used to emphasize the eyelids and/or to change the perceived shape of the eyes. They contain special ingredients that apply color where it is needed in a precise and controlled manner. Eyeliners are available in a wide range of hues, from classic black to more adventurous options with glitter-flecked colors.

Eyeliners contain specially selected ingredients that help prevent the growth of potentially harmful microorganisms. The products are specially formulated to ensure that potentially harmful microorganisms cannot grow and multiply. The safety of eyeliners is established by selection of ingredients that are safe and suitable for this purpose. In addition, eyeliners are assessed for their potential to cause skin irritation or cause allergic reactions. The FDA has issued an alert for Eye Makeup products such as kohl, kajal, al-kahl, or surma, typically applied as Eyeliner. These traditional Eye Makeup products often contain lead and are not permitted in any cosmetic or personal care product in the U.S. .

The ingredients in eyeliners vary depending on the type of eyeliner. Film formers, thickeners, and pigments are the basic kinds of ingredients that are used in eyeliners. Film formers deposit a thin layer on the skin, while thickeners help stabilize the formula so it will stick to the lids. Pigments include iron oxides to create blacks and browns, ultramarine for blue, chromium oxide for green, and titanium dioxide for white. Some eyeliners may contain skin nourishing or skin positive/negative ingredients, such as Propylene Glycol, which is a skin conditioner and humectant.

When it comes to the positive aspects of eyeliners, they can enhance the appearance of lashes, draw attention to the eye, and alter the eyes perceived shape. Contrary to popular belief, liquid liners can be the easiest to handle and can create a clean line. Creams and gels require a brush and are also fairly goof-proof because they can be smudged for a smoky look or applied in a heavy, dramatic line. Pencils tend to be waxier than other liners and more likely to smear. But they can also be easier to work into the lash line for a natural effect.
