What is melanin? What is its function and where is it produced?

Can you recall your school science classes? What makes green leaves green? Yes, the green pigment in leaves is due to chlorophyll produced by chloroplasts. While most leaves are green, have you ever wondered what gives our bodies their color?

What is melanin?

Melanin is the substance in our bodies that produces eye, skin and hair pigmentation. The more melanin your body produces, the darker your skin, hair, and eyes will be.

Melanin production depends on many factors. One of them is definitely your genetics. Additionally, melanin production is also based on the amount of sunlight a person’s ancestors had.

Melanin is nothing but a complex polymer arising from the amino acid tyrosine. This substance is found in animal and human skin. Melanin varies by level. So now you know what makes your unique skin tone, eye color, and hair color.

Main function of Melanin

Melanin provides pigment to your eyes, hair, and skin. It also absorbs potentially harmful UV rays. Additionally, it protects your cells from sun damage.

Where is melanin produced in the body?

This substance is produced in melanocytes. Cells are located in many areas of the body. These areas are:

  • The innermost layer of the skin

  • Certain areas of the brain (substantia nigra and locus coeruleus)
