History: Skin is a protective organ that covers the body and merges with the mucous membranes at the openings of the body such as the mouth and anus. It is attached loosely to underlying tissues. It also varies in thickness from 0.5mm on the eyelids to 1/7 inch or more on the palms and soles. Function of the skin is to protect the body from damaging external agents like extremes of temperature and invades organisms like viruses, bacteria, fungi, and parasites. Specialized nerve receptors in the skin allow the body to sense pain, touch, and pressure. Skin plays a role in temperature regulation, protection from ultraviolet light, in the manufacture of vitamin D and in attracting the opposite sex. Egyptians: Using facial decoration to gain attention or intimidate enemies in battle are cultural constants in history. There is so much evidence that proves skin care and cosmetics have been with us for a very long time. The first archaeological evidence of cosmetics is from Ancient Egypt about 6000 years ago. It was an important aspect of their daily culture and it was incorporated in their mummification and burial traditions. Archaeologists found small clay pots of makeup in even the most humble tombs. Cosmetics protected the Egyptians from the elements, warded off the sun’s burning rays, and repelled insects. The application of makeup also served as a ritual to honor their gods and goddesses. The Ancient Egyptians had a lot of makeup formulas. Metal ore, copper, and semi-precious stones were ground into powder for eye-shadow. Adding water, oil, or animal fat made the color darker and gave the eye a more dramatic look. Kohl is dark eyeliner in
