ABSTRACT
INTRODUCTION Although people of skin color comprise the majority of the world’s population, the literature on the characteristics of the stratum corneum (SC) structure and function with skin of color is limited. Several groups over the past decades have attempted to decipher the underlying differences in skin structure and function in different racial skin types. However, most of these studies have been of small scale, and in some studies interindividual differences in skin quality overwhelm any racial differences. There has been a recent call for more studies to address genetic and phenotypic differences among different racial groups, and in this respect several large scale studies have been conducted recently.
