Detailed explanation-1: -Melanocytes, found in the deep basal layer of the epidermis, contain brown granules called melanin. Besides contributing to skin color, melanin provides protection during episodes of sun exposure. Carotene found in subcutaneous fat tissue contributes to the yellowish color of the skin.
Detailed explanation-2: -Melanin is predominantly restricted to the basal layer (or Stratum basale) of the human epidermis, where it is found in both melanocytes (MCs), the cells that make melanin, and in nearby keratinocytes (KCs), the cells of the epidermis that accept melanin.
Detailed explanation-3: -Skin color is determined by a pigment (melanin) made by specialized cells in the skin (melanocytes). The amount and type of melanin determines a person’s skin color.
