Fig. 5.

Melanin distribution as a function of depth in the epidermis in skin types I and VI. Percentage of melanin content in layers across epidermis from the basal layer to the top of the epidermis for volar arm (circle) and dorsal forearm (asterisk) corresponding to skin type I (a) and skin type VI (b). Data represent the average of the melanin content in layers of five different stacks acquired for the same site. The error bars represent standard deviation of the five measurements. The position across the epidermis was normalized to the thickness of the epidermis.
