In animals, pigmentation plays several important roles, including controlling body temperature and immunity, and providing camouflage and mimicry. Pigmentation also serves as a physical marker of species and sex. Animals that live in perpetual darkness may reduce or lose pigmentation without apparent consequences on fitness. For example, cave-dwelling animals are often marked by a complete lack of pigmentation. This phenotype is also common in humans.
Melanin is a pigment found in skin
The color of our skin is determined by a complex polymer, melanin, made from the amino acid tyrosine. The presence of melanin in our skin varies widely depending on the history of our population’s exposure to sunlight. Melanin is produced in our skin cells called melanocytes, which contain granules of the pigment. The melanin pigment is essential for skin color, as it prevents skin from becoming too light or too dark.

Some may have uneven edges and different colors. These spots can also have a different Breslow thickness, which is important for determining its stage. Melanoma is more common in people with fair skin, while women tend to develop it on their legs and trunk.
UV rays can cause hyperpigmentation
Besides causing hyperpigmentation in some people, ultraviolet rays can damage the DNA in cells and destroy collagen through oxidative stress. These wavelengths are most harmful to skin with dark pigmentation, because they absorb flavin. This reaction causes unstable oxygen molecules, or free radicals, to form on the skin. These free radicals damage the collagen structure by poking holes in it. Darker skin is more sensitive to blue light, resulting in hyperpigmentation in darker skin. Lighter skin is largely untouched by the UV rays.
