The more common product is eumelanin (brown) but in the presence of cysteine, pheomelanin can be formed (red to yellow). Melanin is formed primarily in the melanocyte, located in the inner layers of the skin where melanin and carotene blend to produce the skin color as well as the color in the eyes and hair.

What is the function of melanin in the human body?

In its various forms, melanin fulfills a variety of biological functions, including skin and hair pigmentation and photoprotection of the skin and eye. Pigmentation of the skin results from the accumulation of melanin-containing melanosomes in the basal layer of the epidermis.

Which is a function of melanin produced by the skin?

Melanin is a UV-absorbing agent and is able to protect the skin against the effects of UV light on the skin's surface. It also offers protection against UVB and blue light. Eumelanin protects the skin from UV light, whereas pheomelanin does not.

Which produces melanin?

What color is melanin?

Genetics and evolution of hair and skin colour

How can I increase melanin production?

Eating vitamin C–rich foods like citrus, berries, and leafy green vegetables may optimize melanin production. Taking a vitamin C supplement may help as well. Shop for vitamin C.

Is melanin good or bad?
