What are UV Rays?
UV (Ultraviolet Radiation) are invisible rays omitted from the sun that cause suntans, sunburns, accelerating aging and wrinkles, and in some cases, skin cancer. Durascreen® Sunblock can help heal the burn from UVA, UVB and UVC rays.

UVA rays: long-wave solar rays of
320 - 400 nanometers
These are present year-round, are relatively constant in their
intensity, and penetrate the skin more deeply than UV-B. They
contribute to premature aging and/or wrinkling, sunburn and
skin cancer and, since they are present all year long, there
is a need for year-round sun protection. |

UVB rays: short-wave solar rays of
290 - 320 nanometers
Often described as "burning rays", you know that they have affected
you when your skin starts to turn pink or tan. They are at their
strongest intensity between the hours of 10 a.m. and 3 p.m.
and more damaging during the summer than in winter. These rays
are the most common cause of sunburn and can also contribute
to premature aging/wrinkling, a permanent clouding of the eyes
(cataracts) and over time cause skin cancer and even an alteration
in the immune system. |

UVC rays: very-short solar rays of
200 - 290 nanometers
UV-C are in the shortest part of the UV spectrum and are the
most powerful and harmful rays. Fortunately, they are filtered
out by the ozone layer and don’t reach the Earth. This
is why it is so important to maintain and protect our ozone
layer.
