The melanin is used to protect the cell's nucleus from the UV radiation from the sun. Since the upper layers of the skin are dead, there either is no nucleus remaining, or there simply is no need to protect the nucleus, therefore melanin granules are needed only in the deeper layers of skin

Melanin is formed by the melanocytes which are in the stratum basale of the epidermis. Keratin is formed by the epithelial cells of the skin in the epidermis.
Melanin is produced by organelles called melanocytes, which are specialized cells located in the skin's epidermis. Melanocytes produce melanin using an enzyme called tyrosinase, which is stored in organelles called melanosomes.
Melanocytes are the pigment-producing cells in the epidermis. They are responsible for producing melanin, the pigment that gives skin its color and helps protect it from the damaging effects of UV radiation.
Melanocytes are found in the basal layer of the skin's epidermis and are responsible for producing the pigment melanin. Melanocytes are specialized cells that play a crucial role in determining the color of our skin, hair, and eyes.

These are found in the basal layer of the dermis. There are two types of the pigment melanin: eumelanin, a group of dark brown (almost black) melanins and peomelanin, a group of reddish and orange melanins.
Melanin is located in your basal cells of the epidermis. Melanin is found in other body locations as well, such as the iris, inner ear, and adrenal gland. Melanin is found in the skin and is a pigment produced by melanocytes. The function of melanin is how light or dark skinned a person is.
Melanocytes phagocytize melanin. First, melanocytes which are present in the lowest or basal layer of the epidermis, produce the pigment melanin. The melanin forms granules called melanosomes. After the keratinocytes take up the pigment, it clusters around the keratinocyte nucleus on the superficial side. This protects the DNA in the keratinocyte nucleus from damage due to UV radiation.
Melanocytes are pigment cells that synthesize melanin. These cells inject the melanin pigment in the living keratinocytes cells (skin cells) of the stratum basale layer of the epidermis. Note: The Melanocyte cells also reside in the stratum basale.
Melanin is produced by the melanocytes, and they are found in the stratum basale of the epidermis.
Melanin is formed by the melanocytes which are in the stratum basale of the epidermis. Keratin is formed by the epithelial cells of the skin in the epidermis.
Melanin in dark skin is primarily located in the basal layer of the epidermis, where it is synthesized by melanocytes and transferred to surrounding keratinocytes. This results in a higher concentration of melanin in the skin, providing protection against UV radiation and giving dark skin its characteristic color.
what layer of the epidermis contains skin color
The primary pigments contained in the epidermis are melanin, carotene, and hemoglobin. Melanin is responsible for skin color, carotene gives a yellow-orange hue, and hemoglobin contributes to the red tones in the skin.
Melanin is produced by organelles called melanocytes, which are specialized cells located in the skin's epidermis. Melanocytes produce melanin using an enzyme called tyrosinase, which is stored in organelles called melanosomes.
Melanocytes are located in the epidermis primarily to produce melanin, the pigment responsible for skin color and protection against ultraviolet (UV) radiation. By residing in the epidermis, they can efficiently transfer melanin to surrounding keratinocytes, aiding in the formation of a protective barrier against UV damage. This positioning also allows for a rapid response to sun exposure, promoting increased melanin production to shield deeper layers of the skin.
