It also protects the genetic material stored in your cells by keeping out harmful UV rays.īut keep in mind that melanin alone isn’t enough to protect your skin from sun damage. The substance absorbs light from UV rays and redistributes it toward the upper layers of skin. When you spend time out in the sun, your body produces more melanin. Additionally, people who’re born with clusters of melanocytes have freckles. People with more melanin generally have darker skin, eyes and hair compared to those with little melanin. However, the amount of melanin produced by these melanocytes varies. Typically, all humans have the same number of melanocytes. Your unique combination of eumelanin and pheomelanin is responsible for your skin, hair and eye color. While eumelanin and pheomelanin control the colors of things you see (such as skin, hair and eyes), neuromelanin is responsible for the color of your neurons. People who have equal parts eumelanin and pheomelanin have red hair. This type of melanin pigments your lips, nipples and other pinkish parts of your body. When there’s no black eumelanin and a small amount of brown eumelanin, it results in blonde hair.
People with brown or black hair have varying amounts of brown and black eumelanin. Eumelanin is responsible for dark colors in skin, eyes and hair. There are two types of eumelanin: black and brown. There are three different types of melanin, including: The stria vascularis of your cochlear duct (part of your inner ear).The medulla and zona reticularis (areas of your adrenal gland).The substantia nigra and locus coeruleus (areas of your brain).These cells are located in different areas of your body, including:
