Melanin

Melanin is a natural pigment found in the skin, hair, and eyes of humans and many animals. It is responsible for the color of these features, ranging from black to brown to lighter hues. Melanin plays a crucial role in protecting the skin from ultraviolet (UV) radiation by absorbing sunlight, which helps reduce the risk of skin damage and skin cancer. The amount of melanin a person has is influenced by genetics, environmental factors, and exposure to sunlight. Overall, melanin is vital for coloration and protection against sun-related harm.
