Answers:
A tan occurs when the skin absorbs ultraviolet radiation (commonly called "UV rays"). As a response, the skin produces a substance known as melanin, which darkens the skin's outer layers. While many believe that a tan makes us appear healthier, a tan is actually a sign that the skin has been damaged. It's similar to the beginning stages of a burn.
