Kohl (Arabic: كُحْل, romanized: kuḥl), Kajal, Kajol, or Tiro is an ancient eye cosmetic, traditionally made by grinding stibnite (Sb₂S₃) for use similar to that of charcoal in mascara. It is widely used in the Middle East and North Africa, South Asia, Caucasus, West Africa, and the Horn of Africa, typically as eyeliner to contour and/or darken the eyelids. The content of kohl and various ways to prepare it differ based on tradition and country. Several studies have questioned the safety of kohl due to the dangers of lead poisoning. Importing kohl into the United States is banned.
