Useful Information about Tanning
The Sun
The sun is the source of all living beings on earth. Light and
warmth emitting from it have a huge impact on our health
and physical well-being – as can be experienced during the
turn of seasons or on vacation. A bronzed skin is usually put
on a level with a healthy, attractive appearance and thus
enhances the natural self confidence and personal
comfort. At the same time, a tan has a biological purpose –
protecting our skin from sunburns, e.g. during summer
vacation.
Tanning
Tanning is stimulated by a certain component of the light
spectrum, whether natural from the sun or artificially
created.
Sunlight contains a visible component, perceived as light, as
well as invisible components, recognised as warmth and
radiances that can redden our skin or even burn it.
Radiances that tan our skin belong to the invisible ultraviolet
(UV) radiation. This range is divided into UVA, UVB and UVC
radiation.
The perfect tan is received with a preferably intense UVA
radiation, a small amount of UVB and no UVC radiation.
The sun's UVC radiation is stopped by the atmosphere while
UVB and UVA radiation can tan the skin. However, the
rather high amount of UVB radiation in the sunlight can
quickly lead to excessive irritation, reddening, and finally sun
burns of pale skin.
UVA Tanners
The UVA tanners by efbe-Schott have a more favourable
composition of UVA to UVB radiation compared to natural
sun light. The intensity of tanning UVA radiation is
significantly higher than in natural sunlight while at the same
time the harmful UVB portion has been reduced to a
fraction of the sunlight. As a result, you tan faster and
