How does our Skin Tan?

By Christian Besoiu

As soon as we step outside we are in contact with the sun. The Sun emits UV rays, which penetrate our skin, and breaks down our DNA. Our body, in order to protect itself from decaying DNA it produces Melanin and that makes our skin turn darker. The darker your body is you are more protected from the sun. But if you spend too much time out in the sun exposed to UV rays you body cannot produce enough Melanin that fast so your body burns. Some people are fair skinned and there body doesn’t produce Melanin at rate enough to tan, so they burn really easily.
