Cosmetics

Cosmetics are substances applied to the body for cleansing, beautifying, or altering one's appearance.

These products consist of chemical compounds derived from natural sources or created synthetically. The term comes from the Greek word *kosmetikos*, meaning the technique of dress and ornament. In the United States, the Food and Drug Administration (FDA) defines cosmetics as products intended to clean or beautify without affecting the body's structure or functions. This broad definition includes perfumes, teeth-whitening strips, and eye shadow. However, the FDA specifically excludes pure soap from this category.

Cosmetic products serve several distinct functions depending on their chemical makeup and intended use. Skincare cosmetics focus on protecting or replenishing the skin through cleansers, toners, serums, and moisturizers. Personal care cosmetics include items like shampoo and body wash used for general hygiene. A specific subset is known as makeup, which primarily uses color pigments to enhance or change appearance. This can include concealing blemishes or adding color to the face. In extreme cases, makeup is used for performances to make a person resemble a different creature or object.

Applying decorative cosmetics often follows a specific sequence to achieve a smooth result. A person may begin with a primer, which is a transparent or tinted layer that creates a smooth base. Next, a concealer is applied to hide specific marks or blemishes. Concealer is typically thicker and more heavily pigmented than other products. After this, foundation is spread across the entire face to create an even skin tone.

To add color, one might use rouge or blush on the cheeks. Finally, bronzer or highlighter can be used to add a tanned appearance or a shimmer effect. These products can exist as liquids, creams, powders, or even sticks.

Humanity has used cosmetics for thousands of years, beginning with ancient Sumerians and Egyptians.

Ancient Egyptians utilized kohl for the eyes and castor oil as a protective balm.

Later, Romans used skin creams made from rose water, olive oil, and beeswax. Throughout history, social attitudes toward these products have shifted constantly. In some eras, cosmetics were widely accepted, while in others, they were openly frowned upon. Despite these changing views, people have always sought to achieve certain ideals of appearance through these tools.

History also shows that early cosmetics could be extremely dangerous due to a lack of scientific knowledge. For many centuries, the absence of regulation led to products that caused blindness, deformities, or death. For example, the use of ceruse, or white lead, was common during the Renaissance. In the 19th century, lead poisoning from red and white lead makeup caused skin blackening and weakened tooth enamel. In Japan, white lead was also used for traditional face makeup. Even in the early 20th century, a mascara called Lash Lure caused blindness.

Scientific advances eventually led to the creation of safer, non-hazardous formulas.

The cosmetics industry transformed into a massive global enterprise during the 20th century. In 1882, Lillie Langtry became the first celebrity to endorse a commercial product by lending her name to face powders. During the 1910s, entrepreneurs like Elizabeth Arden and Max Factor helped develop the modern market. By the beginning of the 21st century, the industry had become a multibillion-dollar business. L'Oréal is currently the world's largest cosmetics company, having been founded in 1909 by Eugène Schueller.

Today, while many products are tested for safety, some ingredients like PFAS or formaldehyde releasers remain controversial.

Cosmetics connect to many broader social and political ideas. While traditionally used mainly by women, the use of makeup by men has increased in the 21st century. Some groups have also used cosmetics to protest social standards. In 1968, protesters at the Miss America pageant threw feminine products into a "Freedom Trash Can." They viewed these items as instruments of female torture or enforced femininity. Today, regulatory agencies like the European Union maintain stringent rules to ensure safety.

This complex field continues to bridge the gap between science, art, and social identity.
