Do we tan? But what must be the reason behind it?

Almost everyone of us must have tan lines or uneven Skin tone or complexion that we would never wish to have or rather we would wish that we could wash it off. But getting rid of it is really a difficult task. Tan is the body’s attempt of protecting itself from the damaging UV rays of the sun. And melanin is the actual chemical which is responsible for tanning. Our skin releases this chemical under the surface layers of the skin to help in absorbing the UV radiation. The amount of melanin that your body releases is directly proportional to the body exposure to the sun or the harmful UV rays.
