The characterization of a person as “beautiful”, whether on an individual basis or by community consensus, is often based on some combination of inner beauty, which includes psychological factors such as personality, intelligence, grace, politeness, charisma, integrity, congruence and elegance, and outer beauty which includes physical attributes which are valued on an aesthetic basis.
Standards of beauty have changed over time, based on changing cultural values. Historically, paintings show a wide range of different standards for beauty. However, humans who are relatively young, with smooth skin, well-proportioned bodies, and regular features, have traditionally been considered the most beautiful throughout history.
A strong indicator of physical beauty is «averageness».When images of human faces are averaged together to form a composite image, they become progressively closer to the «ideal» image and are perceived as more attractive. This was first noticed in 1883, when Francis Galton, cousin of Charles Darwin, overlaid photographic composite images of the faces of vegetarians and criminals to see if there was a typical facial appearance for each. When doing this, he noticed that the composite images were more attractive compared to any of the individual images.Researchers have replicated the result under more controlled conditions and found that the computer generated, mathematical average of a series of faces is rated more favorably than individual faces.]It is argued that it is evolutionarily advantageous that creatures are attracted to mates who possess predominantly common or average features, because it suggests the absence of genetic or acquired defects. There is also evidence that a preference for beautiful faces emerges early in infancy, and is probably innate, and that the rules by which attractiveness is established are similar across different genders and cultures.
A feature of beautiful women that has been explored by researchers is a waist–hip ratio of approximately 0.70. Physiologists have shown that women with hourglass figures are more fertile than other women due to higher levels of certain female hormones, a fact that may subconsciously condition males choosing mates.
People are influenced by the images they see in the media to determine what is or is not beautiful. Some feminists and doctors[vague] have suggested that the very thin models featured in magazines promote eating disorders,and others have argued that the predominance of white women featured in movies and advertising leads to a Eurocentric concept of beauty, feelings of inferiority in women of color,and internalized racism.
The black is beautiful cultural movement sought to dispel this notion.
Fatima Lodhi, a young diversity and anti-colorism advocate from Pakistan, claims that
«Beauty comes in all shapes, shades and sizes».
The concept of beauty in men is known as ‘bishōnen’ in Japan. Bishōnen refers to males with distinctly feminine features, physical characteristics establishing the standard of beauty in Japan and typically exhibited in their pop culture idols. A multibillion-dollar industry of Japanese Aesthetic Salons exists for this reason.
