P&G researchers were presenting their latest findings on what makes for “exceptional agers,”those lucky consumers who seem to avoid the sags and bags and dull skin tone that mark so many of us as we get older. The study, “Genetic and Lifestyle Factors Contribute to Youthful Facial Appearance,”was conducted by P&G researchers, as well as teams from 23andMe, Inc. and Massachusetts General Hospital and Harvard Medical School.As part of a Multi-Decade and Ethnicity (MDE) study, teams studied skin aging in women aged 20-74. Among the 155,000 responses obtained from unrelated women of European descent, about 7% (more than 10,800) were identified as “exceptional skin agers.”
