Melanin production and distribution as response to UV radiation. Outline of the melanin unit. The melanin content of each layer is a function of melanin delivered from the melanocyte (green arrows), melanin degradation (red arrows) and the melanin in the cells moving upwards (blue arrows). The distributed melanin absorbs UV radiation (described by decreasing darkness of the arrows with increasing depth). Increase of the UV radiation reaching the basal layer triggers signal substance production. In turn, the signal substances stimulate melanogenesis and dendrite growth in the melanocyte (pink arrow).
