Mascara is makeup that makes your eyelashes look longer and thicker. If you wear mascara while watching a really sad movie, you may end up with black smudges under your eyes.
Some people wear mascara every day, to darken their lashes or accent their eyes. Others save mascara — along with lipstick and eye shadow — for special occasions. Some form of mascara has been around for thousands of years, dating back to ancient Egypt, when kohl was used to color eyelashes. In English, this cosmetic was called mascaro from the 1880s until the 1920s, from the Italian word maschera, or "mask."
