Melanin

The amount of melanin you have in your skin is determined by your genes- it is a genetic trait you were born with inherited from your mom and dad.

The sun makes skin get darker.

In addition-

The sun's UV rays are absorbed by melanin in varying concentrations resulting in different skin colors/freckles/tans etc....

The lighter a person's natural skin color, the less melanin the skin has to absorb UV and protect itself. The darker a person's natural skin color, the more melanin the skin has to protect itself.
