Melanin and keratin are both important components of our skin, hair, and eyes, but they have distinct functions.
- Melanin is a pigment responsible for our skin, hair, and eye color. It is produced by specialized cells called melanocytes and comes in two main forms: eumelanin (dark brown or black) and pheomelanin (red or yellow). Melanin's primary role is to protect the skin from harmful UV radiation.
- Keratin, on the other hand, is a fibrous protein that provides structure and strength to our skin, hair, and nails. It forms the outer layer of our skin, called the epidermis, and is also a major component of hair and nails.
In summary, melanin is a pigment that dictates color, while keratin is a protein that provides structure and protection.
