Mascara is a cosmetic used to darken, colour, thicken, lengthen, or define eyelashes. Historically, it was (and still is) usually black, but now it also comes in many colours and tints. Mascara comes in three forms: liquid, cake, and cream. It is available in tubes with wand applicators. Ingredients in mascara include water, wax thickeners, film-formers, and preservatives.
