prUV is 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.
Use prUV 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..
