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 ones appearance (makeup) can be used to conceal blemishes, enhance ones natural features (such as the eyebrows and eyelashes), add colour to a persons face, or change the appearance of the face entirely to resemble a different person, creature or object.
