Cosmetics are constituted mixtures of chemical compounds derived from either natural sources, or synthetically created ones. Cosmetics have various purposes. Those designed for personal care and skin care can be used to cleanse or protect the body or skin. Cosmetics designed to enhance or alter one's appearance (makeup) can be used to conceal blemishes, enhance one's natural features (such as the eyebrows and eyelashes), add color to a person's face, or change the appearance of the face entirely to resemble a different person, creature or object. Due to the harsh ingredients in makeup products, individuals with acne-prone skin are more likely to suffer from breakouts. Cosmetics can also be designed to add fragrance to the body.
The word cosmetics is derived from the Greek κοσμητικὴ τέχνη (kosmetikē tekhnē), meaning "technique of dress and ornament", from κοσμητικός (kosmētikos), "skilled in ordering or arranging" and that from κόσμος (kosmos), meaning "order" and "ornament". Cosmetics are constituted from a mixture of chemical compounds derived from either natural sources, or synthetically created ones.
Though the legal definition of cosmetics in most countries is broader, in some Western countries, cosmetics are commonly taken to mean only makeup products, such as lipstick, mascara, eye shadow, foundation, blush, highlighter, bronzer, and several other product types.
In the United States, the Food and Drug Administration (FDA), which regulates cosmetics, defines cosmetics as products "intended to be applied to the human body for cleansing, beautifying, promoting attractiveness, or altering the appearance without affecting the body's structure or functions". This broad definition includes any material intended for use as an ingredient of a cosmetic product, with the FDA specifically excluding pure soap from this category.
Cosmetics designed for skin care can be used to cleanse, exfoliate and protect the skin, as well as replenishing it, by the use of cleansers, toners, serums, moisturizers, eye creams and balms.
