Differences have been found among blacks, whites, Asians, and Hispanics in various areas of skin structure and function. Among them is the stratum corneum lipid (ceramide) content, which is highest in Asians, then Hispanics, then whites, and lowest in blacks. Melanosomal packaging and percutaneous absorption rates for specific compounds also vary among the different races. Reports supporting the occurrence of difference in TEWL, tyrosinase levels, skin elasticity, and water absorption rates between blacks and whites, and reaction to skin irritation have been conflicting. No significant differences in corneocyte size, skin thickness, and skin biomechanics have been reported.
在皮肤结构和功能的各个方面，已发现黑人、白人、亚洲人和西班牙裔之间存在差异。其中角质层脂质（神经酰胺）含量就是一个差异点，亚洲人含量最高，其次是西班牙裔，然后是白人，黑人含量最低。特定化合物的黑素体包装和经皮吸收率在不同种族之间也有所不同。关于黑人和白人在经皮水分流失（TEWL）、酪氨酸酶水平、皮肤弹性和吸水率以及对皮肤刺激的反应方面存在差异的报道一直相互矛盾。尚未有关于角质形成细胞大小、皮肤厚度和皮肤生物力学方面存在显著差异的报道。
