What is ultraviolet light?

Ultraviolet (UV) light is radiation energy in the form of invisible light waves. UV light is emitted by the sun and by tanning lamps.

The sun discharges three types of ultraviolet radiation:

  1. ultraviolet A (UVA)
  2. ultraviolet B (UVB)
  3. ultraviolet C (UVC)

Only UVA and UVB rays reach earth. (UVC does not penetrate the earth's upper atmosphere.)

Tanning lamps also produce UVA and/or UVB. These artificial rays affect the skin in the same way as do UVA and UVB from the sun.
