Product Description:
The sun's natural rays give warmth,
visible light and ultraviolet light. In regard to their effect on the
skin, the UV spectrum is subdivided into the UV-A, UV-B and UV-C segments.
The longer UV-A wave are gentle to the skin, even at higher concentrations, and
tan the pigments just beneath the surface of the skin. Light in the UV-B
range is what initiates the formation of pigment, but it can also cause sunburn.
The atmosphere shields us against the UV-C rays, which as a result do not reach
the earth's surface. Filtering out these UV-B rays almost entirely will
effectively eliminate sunburn. But the production of melanin would then
not stimulated. This substance is converted into pigment in the cells at
the surface of the skin; it then darkens under the influence of UV-A light,
causing the skin to tan. The UV-A light of the sun is very slow in causing a
tan. Only at intensities higher than those of natural sunlight is UV-A able to
tan the skin more quickly, by means of so-called direct pigmentation of the
pigments already present in the skin. Nowhere on earth the sun can supply UV-A
radiation at this level without an accordingly high share of UV-B. Only a high
performance unit with a costly filter and cooling system can generate this level
of UV output, and that unit is our Dr. Kern UVA-HT 420.
