Full origin of melanin →Frequently Asked Questions
What does melanin do?
It colours skin, hair and eyes, and it absorbs ultraviolet radiation, which shields the DNA in skin cells from sun damage. People with more melanin burn less easily but still need sun protection.
What is the difference between melanin and melatonin?
Melanin is a pigment made in the skin; melatonin is a hormone made by the pineal gland that regulates sleep. The names look alike but they are unrelated.
Can you increase your melanin?
Sun exposure raises melanin production temporarily, which is what tanning is, but that comes with UV damage. There is no reliable evidence that supplements or foods meaningfully raise baseline melanin, which is largely genetic.
