Eyeliners are primarily made of three main elements: film formers, thickening agents, and pigments. Film formers help with the application on the eyelash, thickeners give weight and volume, while pigments give it the color. Eyeliners are tested for toxicity and there are many brands, which are listed in PETA’s cruelty-free list (It indicates that the brands are not tested on animals). The best ones are those that are safe, dry fast, easy to apply, and long lasting without smudging. Moreover, there are drugstore eyeliners, which are less expensive than most luxury brands and are exclusive to select outlets. The differentiating factor would be the price, the ingredients used, and the brand value.
