Multiethnic comparison of facial skin aging

Overt signs of skin aging can differ in type, onset and magnitude across individuals of different races. To understand the molecular basis for these differences, we conducted a study with women of four races/ethnicities spanning in age from 20 to mid-70s; we named this study the MultiDecades and Ethnic (MDE) Study. U.S. women volunteers were African-American, Hispanic and Chinese with ∼25 women in the age groups of 20-24, 40-44, and 60-64 years, and European-descended Caucasian women across each decade from 20-24 to 70-74 years.
