What are melanin and keratin?

Melanin and keratin are two proteins found in the human body. Melanin is responsible for the coloration of the skin, hair, and eyes, while keratin is a structural protein that is found in the skin, hair, and nails.

Melanin

Melanin is a pigment that is produced by cells in the skin called melanocytes. Melanin gives the skin, hair, and eyes their color. The amount of melanin in the skin is determined by genetics, and it can vary from person to person. People with more melanin have darker skin, hair, and eyes, while people with less melanin have lighter skin, hair, and eyes.

Melanin also helps to protect the skin from the sun's ultraviolet (UV) rays. UV rays can damage the skin and cause premature aging, wrinkles, and skin cancer. Melanin helps to absorb UV rays and prevent them from damaging the skin.

Keratin

Keratin is a structural protein that is found in the skin, hair, and nails. It is a strong and flexible protein that helps to protect the body from damage. Keratin also helps to maintain the shape of the skin, hair, and nails.

Keratin is produced by cells in the skin called keratinocytes. Keratinocytes are constantly dividing and producing new keratin. This process helps to keep the skin, hair, and nails healthy and strong.

Keratin can also be found in some other parts of the body, such as the cornea of the eye and the lining of the mouth.
