WHAT IS UV?

Ultraviolet (UV) rays come from the sun and offer us many benefits. However, when exposed for too long, UV rays are strong enough to damage the skin.
UV light is invisible, and there are three distinct types:

  • UVA rays contribute to skin burning, skin cancer and premature ageing. They have a longer wavelength, which means they are able to penetrate deeper into the base layer of the skin.
  • UVB rays have slightly more energy than UVA rays. They can damage the DNA in skin cells directly, and are the main rays that cause sunburns.
    They are also thought to cause most skin cancers[1].
  • UVC rays are created artificially during industrial processes, such as welding.
