Research showed that the average age of people judged the most beautiful is now close to 40. Scientists from Boston University School of Medicine compared celebrities who were listed in People magazine’s World’s Most Beautiful list in 1990 with those listed this year. Three decades ago the average age was 33.2, but this year it was 38.9. The research also showed there had been a shift towards darker skin tones. In 1990, lighter skins easily dominated the Most Beautiful list, making up 88 per cent. By 2017, lighter-skinned stars had fallen to 70.4 per cent.
