What is melanin?

Melanin is a natural pigment that gives color to the skin, hair, and eyes in humans and animals. It is produced by cells called melanocytes and plays a role in protecting the skin from the harmful effects of ultraviolet (UV) radiation from the sun. Melanin also helps determine the color of an individual's skin, hair, and eyes, with higher levels of melanin resulting in darker skin, hair, and eyes.

Melanin is a natural pigment found in humans and other animals that gives color to skin, hair, and eyes. It is produced by cells called melanocytes and is responsible for the wide range of skin tones seen in different populations around the world. Melanin also acts as a natural sunscreen, protecting the skin from harmful UV radiation. The amount and distribution of melanin in the skin is determined by genetics and can be influenced by factors such as exposure to sunlight. People with darker skin have more melanin, which provides better protection against UV radiation, while people with lighter skin have less melanin and are more susceptible to sunburn.
