Which cells in the epidermis are responsible for absorbing UV light and contributing to skin pigmentation?

Melanocytes are specialized cells located in the epidermis that play a crucial role in skin pigmentation and protection against ultraviolet (UV) light. These cells produce a pigment called melanin, which is responsible for the coloration of the skin, hair, and eyes. When the skin is exposed to UV light from the sun, melanocytes increase the production of melanin as a protective response. This helps to absorb UV radiation, thereby reducing the risk of skin damage and the development of skin cancers. The presence of melanin not only provides the skin with its various shades and tones but also acts as a natural barrier against UV rays, helping to limit DNA damage in skin cells.
