Abstract
Melanin is synthesized by the melanocytes in basal layer of epidermis and distributed over all the layers of skin including corneocytes in stratum corneum, outermost layer of the epidermis. Melanin of corneocytes was stained using Fontana-Masson method and quantified by image analysis. The correlation between melanin contents and skin color value was estimated in the skin of 71 Korean women. Melanin covering area (MCA) showed good correlation with $L^*$ value and $ITA^{\circ}$ (Individual Typology Angle) (r = 0.6049, 0.6651, respectively). MCA can be used as new parameter for skin color study and has potential application for evaluating the efficacy of the skin whitening cosmetics.
