Pigment-producing cell; protects from UV rays.

Melanocytes are the pigment-producing cells that protect skin from UV rays. They synthesize melanin, the pigment that determines skin color and provides a shield against ultraviolet radiation. Melanin is packaged into melanosomes and transferred to nearby keratinocytes, increasing pigmentation in areas exposed to sunlight and helping absorb and dissipate UV light to reduce DNA damage in skin cells. Langerhans cells are immune cells in the epidermis, desmosomes are cell–cell adhesion structures, and keratinocytes are the main epidermal cells that form the barrier but do not produce pigment themselves.
