Sun Facts UVA & UVB


Let’s start at the top, at the very source to be exact; the sun. The sun is our source of heat and energy and reaches the earth through UV (Ultra Violet), a broad spectrum of wavelengths. UV comes in three variations –

  • UVA which can penetrate through the ozone layer (Earth’s protective shield)
  • UVB which the ozone layer can partially absorb
  • UVC, which is completely absorbed by the atmosphere

In earlier years, UVA rays were thought to be “safe,” and this lead to the advance of tanning and sun beds. Since then, scientific research has led us to discover that it is both UVA and UVB rays that we should be mindful of, as they can penetrate the skin and cause great damage.

How do you protect yourself from UVA & UVB rays?

Broad spectrum sunscreen can act as your best defence to both harmful UVA and UVB rays, along with other simple precautions to take such as wearing a hat and sunglasses, wearing protective clothing and staying in the shade.

Keep in mind to look for a broad spectrum sunscreen with an SPF of 15 or more to get the best protection!
