What causes melanin deficiency?

Vitiligo is caused by the lack of a pigment called melanin in the skin. Melanin is produced by skin cells called melanocytes, and it gives your skin its colour.

Does tanning increase melanin?

There is no such thing as a safe tan. The increase in skin pigment, called melanin, which causes the tan color change in your skin is a sign of damage.

Does melanin decrease with age?

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 is skin color called?
