Figure 3: The Impact of UV Radiation on Human Skin.

Figure 3:

The three forms of UV light are shown: UVA and UVB passes through the atmosphere, while UVC is prevented entry by the Ozone layer (the surrounding black line). The amount of UVA and UVB that reaches the skin is dependent upon environmental conditions as depicted by the clouds. Upon reaching the skin, UVA either reflects or penetrates deeper into the skin, whereas UVB is primarily reflected or absorbed by melanin. Effects of UV light on the skin and skin cells are represented throughout the figure.
