What makes up melanin?

Biochemical Mechanism. Melanin is the pigment that produces the wide variation seen in skin and hair color in humans. Melanin is synthesized by cells in the skin and hair follicles called melanocytes. Two major classes of melanin are known: eumelanin, a brown-black pigment; and pheomelanin, an orange-to-red pigment.

Is there a melanin supplement?

While there are no safe, proven melanin boosters on the market, researchers have found a chemical compound that may boost melanin levels in the skin. This compound created a tanned appearance when researchers applied it to human skin. They believe the compound shuts off certain enzymes that inhibit melanin production.

What triggers melanin production?

UV-A rays from the sunlight penetrate into the lower layers of the epidermis and trigger the melanocytes to produce more melanin. Melanin is produced as a defence mechanism. Sunlight is the major cause of increased melanin production. Other factors include hormonal imbalances, aging and inflammation processes.

What are the 3 types of melanin?
