Special references
With the high-pressure lamps by the
higher radiating power a substantially
more preserving tanning is obtained. The
face skin, which becomes more slowly
brown also in the natural sun than the
remaining parts of the body, is gebraeunt
by this increased achievement
intensively.
l The irradiation distance should amount
to at least 140 cm.
l The irradiation time with the high-
pressure lamps should with skin-typ II
max. 30 minutes amount to.
l While the irradiation use an eye
protector.
