Human skin color indirect DNA damage to the skin and the body naturally combats and seeks to repair the damage and protect the skin by creating and releasing further melanin into the skin's cells. With the production of the melanin, the skin color darkens, but can also cause sunburn. The tanning process can also be created by artificial UV radiation. There are two different mechanisms involved. Firstly, the UVA-radiation creates oxidative stress, which in turn oxidizes existing melanin and leads to rapid darkening of the melanin, also known as IPD (immediate pigment darkening). Secondly, there is an increase in production of melanin known
Pigment pigment derived from a parasitic insect found in Central and South America—attained great status and value in Europe. Produced from harvested, dried, and crushed cochineal insects, carmine could be—and still is—used in fabric dye, food dye, body paint, or—in its solid lake form—almost any kind of paint or cosmetic.
