Melanogenic refers to the production or synthesis of melanin, the pigment in skin and hair that provides protection against UV radiation. Synonyms for melanogenic include melanin-forming, melanogenesis-inducing, pigmentation-stimulating, and melanocyte-activating. These terms describe the process by which melanocytes, specialized cells in the skin, produce and deposit melanin granules. Other related terms include melanocyte stimulating hormone (MSH), which stimulates melanogenesis, and tyrosinase, the enzyme responsible for the synthesis of melanin. Understanding the terminology associated with melanin production is important for research into cosmetic and medical interventions aimed at regulating or modulating pigmentation in the skin.
