Modern cosmetics are associated with beauty and well-being. They are used to highlight and accentuate features and decrease attention to perceived imperfections. Beauty has been appreciated since the beginning of civilization, and the development of cosmetics has progressed with human history, drawing on both scientific and cultural evolution. In modern Western societies, a relationship is established between body beauty, intelligence and high purchasing power.

There is evidence of body painting used as camouflage for hunting and to show ferocity in inter-tribal wars as early as prehistoric times. The Picts, a tribe living in Scotland in 1000 BC, were named for the Latin term pictus (painted) by the Romans (Butler, 2000). Aboriginal body painting has been used by Australian aborigines for thousands of years. The colours and patterns vary between regions and tribes. Hours can be spent applying body paint, often by a relative, in preparation for religious and cultural ceremonies.

Egypt’s last queen, Cleopatra (51–30 BC), bathed in goat’s milk to give her softer, smoother skin. There is extensive evidence of the Egyptians’ use and importance of cosmetics; indeed many were placed in tombs along with the most precious artefacts needed in the afterlife. Items recovered by archaeologists have included leaves of henna from which the Egyptians extracted dye to colour the palms of the hands, soles of the feet, nails and hair, red ochre for face colouring, green colouring from malachite (copper carbonate ore) for the eyes, and kohl for eyelashes and eyebrows. Jars containing oils, unguents and ointments used to cleanse, moisturize and decorate the skin, together with incense, equipment for pulverising and preparing cosmetics, razors, and so forth were frequently recovered in tombs dating as far back as 3000 BC (Poucher, 1941). Indeed there is clear evidence of the use and continued development of cosmetics utilizing minerals, plants and animal products throughout the Middle East, India, China and Europe (Butler, 2000). From the 15th and 16th centuries onwards, the rapid advancement in trade brought new opportunities that have led to the global industry in cosmetics we see today. Helen Butler provides an excellent and thorough history of the development of cosmetics in her chapter ‘Cosmetics Through the Ages’ (Butler, 2000). In addition, our knowledge of anatomy, physiology, metabolism, toxicology and other related sciences has provided a greater understanding of the skin, hair and body, facilitating the development of more effective and safer cosmetic products that meet the demands and expectations of the consumers of this century.

Many factors have contributed to the multibillion-dollar cosmetic product industry we enjoy today. Over the course of the last century, the role of women changed with increasing participation in the labour market, leading to greater awareness of self-image but also more disposable income to devote to appearance. Marketing of cosmetic products became more sophisticated with the introduction of new technologies from mass-produced print magazines, to television and the Internet with its highly effective social me...
