Reduced scattering coefficient ${\mu }_{\mathrm{s}}^{\prime }$ of Asian (a) epidermis, (b) dermis, and (c) subcutaneous fat are compared with the reported values of Caucasian and African skin tissues. The crosses correspond to Caucasian epidermis, dermis, and subcutaneous fat.¹⁰ The open and closed triangles correspond to African dermis and Caucasian subcutaneous fat, respectively.¹¹ The error bars represent the standard deviation of the reported values.
