WHY DO WE TAN WHEN WE GO OUT IN THE SUN?
Your skin contain a pigment known as melanin which is a kind of natural protection against UV A and UV B rays. When the skin is exposed to the sun’s harmful rays, the melanin cells multiply very fast and the increased melanin in the skin makes the skin look darker. So basically, a tan is simply your skin’s way of protecting itself from further sun damages. Different people tan differently, some more easily than the others depending on various factors, including genes.
