Why do ancient Egyptian wore makeup? For more than beauty reasons. They used two types of eye makeup, Udju and Mesdemet. Each had a different meaning and purpose. Udju was made from green malachite, wimen brushed it across the lid of the eye as a sing of Hathor’s protection. 
The Mesdemet, dark grey or black was made of lead, or specifically galena. Was used by men and women, and proved to be a disinfectant, it also protected the eyes from the sun, and kept flies and bugs away.
An unadorned and thus unprotected eye was believed vulnerable to evil. Outlining the eyes thus became a personal protective amulet drawn right upon the skin; an amulet that once applied could not be lost or misplaced.
Eye makeup, also had spiritual dimensions. Wearing malachite placed one solidly under Hathor's protection throughout Egypt and as far as Byblos. The use of cosmetics in Egypt also differed between social classes, more makeup was worn by the wealthier and the poor wore less.
Also the containers and tools used to apply the makeup were different among social classes. The upper class had containers made of alabaster or fine stones whereas the lower class had containers of clay or wood. J. Illes, S. Boyce, M. Miller
