UVA tanning devices
UVA tanning devices by efbe-Schott feature a more favourable composition of UV
radiation compared to natural sunlight. The intensity of UVA radiation is much higher
than in natural sunlight, while at the same time, the harmful UVB radiation has been
reduced to a fraction of the amount that is present in natural sunlight. In comparison to
natural sunlight, the tanning process is usually accelerated while there is normally no
risk of sunburn. The tanning colour that can be obtained is similar to a natural suntan.
However, the skin's reaction to sun rays varies from one individual to another.
Skin types and exposure times
Each of us knows their skin's individual tanning behaviour when exposed to direct
sunlight. Thus, a similar reaction of our skin may be expected from exposure to artificial
UV light. People who can tolerate the sun very well tend to tan more quickly, while those
who are unable to tan in the sun have only little chance of success when using UVA
tanning devices.
Classification of skin types according to the reaction of the skin that has not been pre-
irradiated to natural sunlight:
Skin type
Always get sunburned quickly, hardly or no tan, even after repeated
I
irradiations (Celtic type)
Almost always sunburn, moderate tan after repeated exposures (fair-
II
skinned type)
Moderately often sunburn, progressive tanning after repeated irradiations
III
(dark-skinned type)
IV Rarely sunburn, rapid onset and clear tan (Mediterranean type)
Be careful when determining your individual exposure time, always taking into account
your personal suntan experience.
Using a tanning device is only recommended for people with skin types II, III and IV.
People with skin type I and children younger than 14 years are not able to tan, neither in
natural sunlight nor when using a tanning device.
