The
first barrier cream to successfully make use
of modern micro pigments (diam. 10-50 nm)
of titanium oxide and zinc oxide. These micro-pigments
offer extremely high factors in UV-filtration,
reflection, and absorption (energy disbursement)
over the entire spectrum of UVA, UVB, and
UVC. Because of their small size, these particles
are no longer visible but appear transparent,
thus they are highly acceptable from a cosmetic
point of view. The substances are also inorganic,
and are considered dermatologically and toxicologically
harmless. Older sun bloc preparations make
extensive use of organic filter substances,
which are now considered dermatologically
questionable. In places like Japan certain
concentrations of these substances are already
prohibited. |

| 'pr-UV'
offers a Light Protection Factor of DIN 20,
which translates into a North American SPF
40. 'pr-UV' is water resistant and will not
come off the skin while swimming or perspiring.
To remove use soap and water. Further skin
friendly ingredients also found in 'pr99'
make 'pr-UV' an excellent skin conditioner
and moisturizer. It's skin type neutral, hypoallergenic,
and non toxic. |

| WHAT
IS THE NATURE OF UV-RADIATION? |
 |
| UV-radiation
are electromagnetic waves on the short end
of visible light. They are classified as
UV"A" (315-380 nm) UV"B"
(280-315 nm) and UV"C" (100-280
nm). The sun is the best known natural source
of this radiation but artificial sources
like high-tech pressure lamps for curing
lacquer, printing inks, photocopy equipment,
and film exposure methods, and welding arcs
are recognized hazards |
| |
| HOW
DOES UV-RADIATION DAMAGE SKIN?
|
|
| UV-A
effects tanning of the skin through the production
of melanin; it can also cause photosensitivity
and light-dermatitis, premature aging of the
skin. Constant exposure may cause ceratitis
and cancers. UV-A penetrates the skin deeper
than B+C but does not have as much energy.
UV-B causes sunburns and the possibility of
skin cancer. UV-C as the radiation with the
highest energy level is extremely dangerous
because it destroys skin cells and causes
cancerous growths. |

| USES
FOR pr-UV |
|
| At
work and at play in sunlight and around artificial
light sources; e.g. skiing, on the beach,
in road construction, farming, landscaping,
welding shops, reproduction or photocopy institutions,
working around UV-curing paints, plastics,
adhesives; for persons with sun allergies
or sunlight sensitivity etc. |
