SOLARIUMS, SUNLAMPS AND SKIN CANCER
ANTI-CANCER COUNCIL OF VICTORIA
Two out of three people in
Australia will develop skin cancer during their lives. This is
the highest skin cancer rate in the world, and is due largely to
our exposure to sunlight (solar UV radiation). People who use
solariums simply add to this already high level of UV exposure,
and probably increase the risk of skin cancer.
Solariums and sunlamps offer
people an artificial tanning process which is claimed to be
effective and harmless. However, there is growing evidence to
suggest that the ultraviolet radiation used in solariums and
sunlamps may damage the skin, and may increase the risk of
developing skin cancer.
In view of this possibility, the
Anti-Cancer Council strongly recommends against the use of
solariums and sunlamps for cosmetic tanning.
Ultraviolet radiation, those rays
which cause skin damage, is made up of three components: UVA, UVB
and UVC. The harmful effects of UVB and UVC have been known for
some time. No UVC from the sun reaches the earth's surface but it
can be created artificially by lamps. UVA was, until recently,
thought to be relatively harmless, but evidence is emerging that
UVA may also cause skin damage, and increase the risk of
developing skin cancer.
Are solariums harmful to
health?
Most solariums claim to use only
UVA.
There are two issues here.
Firstly, the output from solarium
lamps changes over time. If UVB and UVC (both of which are
dangerous in much smaller quantities than UVA) are to be
excluded, solariums need to be tested regularly, especially if
lamps or perspex are changed.
Secondly, researchers no longer
regard exposure to UVA as safe.
Solarium advertising claims that
UVA does not cause skin ageing, nor does it cause skin cancer in
the long term.
UVA radiation penetrates the top
layer of your skin and can cause damage to the lower layer. This
causes skin to age prematurely, with effects that include
roughening, blotchiness, wrinkling and general looseness.
When UVA exposure is sufficiently
great, it may cause sunburn as well as a tan.
There is good evidence now to show
that UVA is a contributing cause (with UVB) of common skin
cancer. In addition, two recent studies suggest that using a
sunbed or sunlamp increases the risk of developing melanoma.
Solarium advertising claims that a
UVA tan actually protects you from sunburn, premature ageing of
the skin, and skin cancer which result from exposure to natural
sunshine.
Whether a tan is brought on be UVA
alone (solariums) or by UVA and UVB together (as in natural
sunlight), the UV dose accumulated while achieving a tan adds to
the lifetime total dose, and to the risk of skin cancer. Although
people who have acquired a suntan may not sunburn as easily as
those without, a tan does not give you sufficient protection
against the harmful effects of everyday levels of sunlight in
Australia. The case of farmers or outdoor workers illustrates
this point; these people tend to have a constant suntan, but
their skin still ages prematurely, and they develop many more
skin cancers than indoor workers.
People with skin that burns easily
and does not tan are the most vulnerable, but those at risk also
include the more olive-skinned people of Southern Europe. Only
those with very dark skins, such as Aboriginal people, seem to be
most immune to skin cancer.
Moreover, UVA only produces a
'satisfactory' tan in those who develop a tan relatively easily
in natural sunshine. Those who burn easily and tan poorly in the
sun are likely to be disappointed with the results from a
solarium.

Solariums pose health hazards
- If the eyes are inadvertently
exposed to UVA, the cornea and the conjunctiva may be
briefly inflamed, and sight may sometimes be permanently
damaged.
- Up to half the people who use
solariums develop minor skin irritations such as redness,
itchiness, and dryness. Solariums can also irritate some
existing rashes. If you use a solarium excessively, your
skin may become more fragile, and may blister.
- Some prescription drugs,
including antibiotics and diuretics, and some cosmetics,
can increase a person's sensitivity to UVA. Use of a
sunlamp or solarium under these conditions may result in
severs sunburn; it can cause and itchy and painful rash
which is sometimes followed by the development of blotchy
darker patches of pigmentation on the skin; and it may
also damage the eyes.
- The UV radiation from sunbeds
has been shown to cause changes in the body's immune
system, although we do not know yet hoe important these
changes are.
PUVA treatment
PUVA stands for psoralens (P) and UVA (the long wavelength of
ultraviolet). It is a medical treatment used for a variety of
conditions, most commonly psoriasis. Psoralens are drugs which
are given by the mouth, or applied to the skin prior to shining
UVA on to the skin. The psoralens sensitise the skin to UVA.
When used under medical
supervision, the treatment is very effective. There is a small
risk of skin cancer associated with the treatment, but is often
outweighed by the unpleasant nature of the underlying skin
condition which is being treated. However, medical supervision is
required to ensure that the correct treatment is given and that
if any problems occur, they are detected and treated early.
Regulations for the use of
solariums and sunlamps
In 1993 the Standards Association of Australia (SAA) Standard
AS2635-1983 set guidelines on the installation, maintenance and
operation of commercial solariums. Included in these is a
recommendation that the form shown in this brochure be read,
understood and signed by every person using a solarium.
Sunlamps that are sold for use in
the home are not controlled by any such guidelines. These
sunlamps often emit high levels of UVB and may even emit the more
damaging UVC. These products should only be used on the advice of
a doctor, and then only under strict medical supervision.
ADVICE TO CLIENTS
Please read carefully the
following information:
- Exposure to ultraviolet light from either sun or a
solarium causes varying degrees of damage to the skin and
eyes.
- Exposure to ultraviolet light accelerates ageing of the
skin and contributes to the development of skin cancer.
- Some people are unable to tan effectively by exposure to
sunlight or solarium light because of skin complexion,
and you should be particularly aware of the possible
danger of exposure to ultraviolet light if :
- you normally have difficulty tanning; or
- you have a very fair complexion.
- There is additional risk and solarium exposure is not
recommended if:
- you have ever been treated for sun spots or skin
cancer; or
- you have ever suffered from an abnormal reaction,
or allergy, to light.
- There may be further risk and caution with solarium
exposure is recommended if you are taking certain
medications by mouth or applying medications or cosmetics
to the skin.
- You should not undergo ultraviolet exposure in this
establishment if you have undergone solarium exposure
within the past 48 hours.
- You should not undergo further solarium exposure within
48 hours of undergoing ultraviolet exposure in this
establishment.
- You should avoid, as far as practical, intentional
exposure to sunlight within 48 hours both before and
after any solarium exposure.
- You must wear protective goggles while undergoing
solarium exposure. Failure to do so may cause both
short-term and long-term eye damage.
