Melanogenesis is a process catalyzed by tyrosinase enzyme leading to synthesis of two types of pigment in the skin: black-brown eumelanin and red-yellow pheomelanin. Pheomelanin is synthesized in the second stage of melanosome maturation, while eumelanin-synthesizing melanosomes are inactive. The black-brown pigment is produced in the third stage of melanosome development. The last, fourth stage of melanosome maturation is characterized by low tyrosinase activity, which reflects the low pigment production in the skin. The process of skin pigment production (melanogenesis) is mainly regulated by solar radiation, hormones and other endo- and exogenous factors. Over- stimulated melanogenesis l…
