EyebrowAn eyebrow is an area of short terminal hairs above each eye that follows the shape of the lower margin of the brow ridges of some mammals. In humans, eyebrows serve two main functions: first, prevention of sweat, water, and other debris from falling down into the eye socket, and second, communication through facial expression. It is relatively common for people to modify their eyebrows by means of hair removal and makeup.
Skin careSkin care or skincare is the practice and process of maintaining and improving the health and appearance of the skin. It includes washing, moisturizing, protecting from the sun, and treating skin problems like acne and dryness. Facial care is skin care for the face. Skin care is at the interface of cosmetics and dermatology. Skin care differs from dermatology by its inclusion of non-physician professionals, such as estheticians and nursing staff.
Food and Drug AdministrationThe Food and Drug Administration (FDA) is a federal agency of the United States Department of Health and Human Services (HHS).Personal care productsPersonal care products are a class of consumer products associated with hygiene and personal grooming. They are marketed to modern consumers as "minimally necessary" or improving appearance or well-being. They are applied on various external parts of the body such as skin, hair, nails, lips, external genital and anal areas, as well as teeth and the mucous membranes of the oral cavity.
BeautyCharacteristic that provides pleasure or satisfactionA Rayonnant style rose window in Notre-Dame de Paris. In Gothic architecture, light was considered "the source and actual essence of all that is beautiful".Beauty is commonly described as a feature of objects that makes them pleasurable to perceive. Such objects include landscapes, sunsets, humans and works of art. Beauty, art and taste are the main subjects of aesthetics, one of the fields of study within philosophy.
Human physical appearanceHuman physical appearance is the outward phenotype or look of human beings. There are functionally infinite variations in human phenotypes, though society reduces the variability to distinct categories. The physical appearance of humans, in particular those attributes which are regarded as important for physical attractiveness, are believed by anthropologists to affect the development of personality significantly and social relations.
Chemical compoundA chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element, called homonuclear molecule, is therefore not a compound. A compound can be transformed into a different substance by a chemical reaction, which may involve interactions with other substances.
European UnionSupranational political and economic unionThe European Union (EU) is a political and economic union of 27 member states that are located primarily in Europe. A supranational union with a total area of 4,233,255 km (1,634,469 sq mi) and an estimated population of just under 452 million as of 2026, its member states generated a nominal gross domestic product (GDP) of around €18.802 trillion in 2025, accounting for approximately one sixth of global economic output.
EyelashAn eyelash (also called lash) (Neo-Latin: cilium, plural cilia) is one of the hairs that grows at the edges of the top and bottom eyelids, spanning outwards and away from the eyes. The lashes grow in up to six layers on each of the upper and lower eyelids.
Formaldehyde releaserA formaldehyde releaser, formaldehyde donor or formaldehyde-releasing preservative is a chemical compound that slowly releases formaldehyde. Formaldehyde-releasers are added to prevent microbial growth and extend shelf life. The intent of these compounds is that they release formaldehyde at levels that suppress microbial growth but sufficiently low to not threaten humans. The use of these chemicals in cosmetics has elicited controversy.PFASPer- and polyfluoroalkyl substances (PFAS or PFASs) are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain. Because of their high chemical and thermal stability, these compounds have long environmental lifetimes, and thus are commonly called "forever chemicals". The first PFAS, polychlorotrifluoroethylene, was synthesized in 1934.
