In fact there are two processes which produce tanning, and
they are simultaneously effective:
- "Indirect tanning". Primarily UV-B stimulates the
production of a substance called "melanin", which is
necessary for tanning. The effect does not show until a
couple of days after the sunbath.
- "Direct tanning". The UV-A and also a part of the visible
light cause quicker browning without reddening or "getting
sunburnt".
The solarium
This solarium emits predominantly UV-A, and also a very small
amount of UV-B.
It possesses some important features which make tanning at
home comfortable and convenient.
The unique type of sun lamp used in this solarium emits
light, warmth and ultraviolet, just like the natural sun.
You can position this solarium so that using it really resembles
lying in the sun: your whole body is tanned evenly, from head
to toe.
For your convenience, but also to prevent unintended
prolonged exposure (e.g. after falling asleep), timer-controlled
automatic switch-off after 30 minutes tanning is incorporated.
As it is with the natural sun, it's wise not to have too much of
the good thing! (See section "UV and your health".)
UV sessions: how often? And how long?
You may have one UV session per day, over a period of
five to ten days. Allow at least 48 hours between the first
two sessions.
After such a course, you may rest the skin for a while.
Approximately one month after a course your skin will have
lost much of the tan. You might then decide to start a new
course.
On the other hand, it is also possible to have one or two
UV sessions per week after a course has elapsed in order
to keep up the tan.
Whatever you may prefer, make sure that you do not
exceed the maximum amount of tanning hours. For this
solarium the maximum is 26 hours (= 1560 minutes) per
year.

very sensitive skin:
- for persons with
normal sensitive skin:
- for persons with
less sensitive skin:
• If you think that the sessions are too long for you
(e.g. if the skin gets taut and tender after the
session), we advise you to reduce the sessions by
e.g. 5 minutes per side of the body.

UV and your health
After an excessive exposure to ultraviolet (from the natural sun
or from your solarium), the skin may develop sunburn.
Beside numerous other factors, such as excessive exposure to
the natural sun, improper and excessive use of your solarium
will increase the risk of skin and eye disease.
The nature, intensity and duration of the radiation on one hand,
and the sensitivity of the individual on the other, are decisive
on the degree in which these affects can occur.
The more skin and eyes are exposed to UV, the more risk
increases of diseases such as inflammation of the cornea
and/or conjunctiva, damaging of the retina, cataract, premature
aging of the skin and skin tumours.
Certain medicines and cosmetics increase the sensitivity to
UV.
Therefore, it is of great importance
- that you follow the instructions in sections "Important" and
"UV sessions: how often? And how long?";
- that you select the advised operational distance of 70 cm
(approx. 27.5");
- that you do not exceed the maximum amount of tanning
hours per year (i.e. 26 hours or 1560 minutes);
- that you always wear the provided goggles while tanning.
Example:
Imagine that you take a 10 day UV course, with a 10 minute
session on the first day and 25 minutes' sessions on the
nine following days.
The entire course then includes (1 x 10 minutes) +
(9 x 25 minutes) = 235 minutes.
Over a year you may have six of these courses.
(As 6 x 235 minutes = 1410 minutes.)
Of course, this maximum amount of tanning hours is valid
for each treated part or side of the body separately.
(E.g. for the front side of your body and for the back side.)
From the table it will be seen that the first session of a
course should have a duration of 10 minutes. This is not
dependent upon individual skin sensitivity.

• To get a beautiful all-over tan it is suggested that
you turn slightly during the session so that the
sides of your body are better exposed to the
tanning rays.
