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: The Dr. Kern UVA HT 420.
