The sun is cruel to exposed skin and long hours in the sun can tan your skin making it dark and dull. Many people have this notion that tanning saves the skin from damage. But hey! Let me clear the fog, safe tanning is not a thing.
Tanning is a defense mechanism against harmful UV rays. As soon as you expose your skin to the harmful ray the melanocytes come into action and start producing a dark pigment called melanin. This melanin pigment darkens your skin which is called tanning. There is evidence that suggests that the risk of skin cancer is increased due to tan.
