Published in the journal JAMA Dermatology, the study compares the 50 celebrities on the 1990 inaugural list with the 135 on this year’s.
Whereas the mean age of those in 1990 was 33, this year it’s 39, skewed upward by the presence of such folks as Oprah Winfrey (63), Viola Davis (51), Tamron Hall and Taraji P. Henson (both 47), and Julia Roberts, who made the cover at age 49—and also made the list cover in 1991, when she was 23.
Star-gazers will note the presence of many African Americans as well on the above list, highlighting another finding of the study: nonwhites comprised 24 percent of the 1990 list but 40 percent this year.
