JudyA suntan is the skin's way of trying to protect itself from the damaging effects of ultraviolet (UV) radiation. When exposed to UV radiation, the skin produces more melanin, a pigment that darkens the skin. This darker pigment helps to absorb and scatter the UV radiation before it can cause more damage to the skin cells.

Why is a tattoo permanent and a suntan is not?
A tattoo is permanent because the ink is injected into the deeper layers of the skin where it remains, whereas a suntan fades as the skin sheds and renews itself over time. The cells that produce the pigment in a suntan are located in the upper layers of the skin and are eventually replaced with new cells.
Describe the change that takes place in your skin when you get a suntan?
When you get a suntan, your skin produces more melanin, a pigment that darkens the skin to protect it from UV damage. This increased melanin production results in the skin appearing darker and acts as a natural defense mechanism to shield the body from further sun exposure.
