Skin care - tanning

By Aibout Hichem Saturday, March 24, 2012 2 comments
A tan is a sign of skin damage. A tan is not a sign of good health but rather a sign that your skin is
trying to protect itself from the sun's ultraviolet (UV) rays. There is no such thing as a ‘safe’ tan.
Exposure to UV radiation from sunlight or a solarium increases your risk of skin cancer and ages
your skin. People with fair skin are at higher risk of skin cancer than people with naturally very
dark skin.
Many people mistakenly believe that having a tan protects their skin against sunburn and further
DNA damage by ultraviolet radiation. However, a tan offers minimal protection (around SPF3).
Even without burning, UVB radiation ages the skin through irreparable DNA damage. Repeated
doses of UVA radiation also contribute to long-term damage, even when no sunburn occurs.
Over the past 30 years, campaigns to heighten awareness of skin cancer have resulted in fewer
people sunbaking. Commonly used alternatives to sunbaking include fake tanning lotions, tan
accelerators and solariums. Each carries potential health risks.
If you want your body to appear tanned, a tanning method that doesn’t use UV radiation is
preferable. When the UV Index level is 3 and above you still need to protect yourself from UV
radiation, even when using alternative tanning methods.
How skin tans

Skin cells in the top layer of skin (epidermis) produce a pigment called melanin that gives skin its
natural colour. When skin is exposed to UV radiation, more melanin is produced, causing the skin
to darken. This is what we know as a ‘tan’. A tan is a sign that the skin is attempting to protect
itself against UV damage. It is not a sign of good health.
There is no ‘safe’ tan. Any method that involves exposure of the skin to UV radiation, either by
sunlight or in a solarium, will cause skin damage. The more your skin is exposed to UV radiation
from any source, the greater the risk of skin cancer and the more quickly skin will age. Compare
the skin on the back of your hand with the inside of your thigh to see the damage caused by years
of sun.
Australians and tanning
The desire for a tan has been part of the Australian culture since the mid-1900s. However, we now
know that deliberately exposing skin to UV radiation can increase your risk of developing skin
cancer.
Australians are exposed to some of the highest levels of UV radiation exposure in the world.
Combined with the fashion for tanned skin, this has led to an epidemic of skin cancer. Australia has
one of the highest rates of skin cancer in the world. More than 1,800 Australians die from skin
cancer each year.
Challenging the ‘tan is beautiful’ myth
Recent public awareness campaigns challenge the perception that tanned skin is more desirable
than pale skin. Despite these campaigns, the desire for the appearance of tanned skin is still high,
especially among younger people. Consequently, alternative tanning methods have become
increasingly popular. If you must tan your body, a tanning method that doesn’t use UV radiation is
preferable.
Fake tanning products
The range of fake tanning products includes:
• Topical dyes – includes tanning lotions, creams, sprays, mousses, combined moisturiser
and fake tan products. These are generally made up of vegetable dyes that stain the skin a
darker colour and give a temporary appearance of a tan. This colour does not stimulate the
production of melanin nor does it provide protection against UV radiation. The dye is shed,
along with dead skin cells, after a few days.
• Bronzers and tinted sunscreens – includes tinted cosmetic and sun protection products
such as moisturisers, foundation, powders and sunscreen. Bronzers provide the skin with
temporary colour which, unlike dyes, wash off with soap and water.
• Tan accelerators – claim to speed up the natural tanning process by stimulating melanin
production in the body. They come in tablet or lotion form.
• Spray tanning booths – these use misters to apply an even coat of fake tan solution to
all, or parts of the body. They are often found at beauty salons, hairdressers and some
gymnasiums.
Tanning lotions
A few fake tanning lotions include sunscreens, ranging from sun protection factors (SPF) 4 to 15.
However, this protection only lasts for a short time following application and not for the duration of
the fake tan. Promoting a fake tanning product as being protective against UV radiation may be
misleading to consumers. Remember, a fake tan product does not protect you from the sun. You
must still use a combination of sun protection measures.
Tan accelerators
Tan accelerators are available in tablet or lotion form. These preparations contain the chemicals
psoralens and tyrosine, among others. These chemicals contribute to the production of melanin,
the pigment responsible for skin colour. With sensitised melanin cells, it is possible to get a suntan
in a shorter time than usual. However, no sun protection is offered.
There is no evidence that the topical use of tyrosine has any effect on melanin cells. When applied
to the skin, tan accelerator products can cause painful conditions, including blistering. Psoralens
should only be used under medical supervision to treat skin problems such as psoriasis.
Using tan accelerators for a long time has also been associated with an increased risk of skin
cancer. When taken by mouth, the possible side effects of tan accelerator products include nausea,
headaches and itchy skin.
A solarium tan is not a safe tan
Some Australians use solariums (also known as sunbeds, sunlamps or tanning beds) with the
mistaken belief that these devices provide ‘safe’ tans. In fact, the opposite is true. Research shows
that UV radiation from solariums can increase your risk of developing skin cancer by 75 per cent if
they are first used before the age of 35.
The International Agency for Research on Cancer (IARC) has moved ultraviolet emitting tanning
beds to its highest cancer risk category and labelled them as ‘carcinogenic to humans’. Solariums
can also cause eye damage, immediate skin damage (such as sunburn, irritation, redness and
swelling) and possible immune system changes.
A solarium tans the skin by radiating it with a concentrated dose of UV, which may be up to six
times as strong as the summer midday sun. Solarium use is not a safe way to tan and a solarium
tan won’t protect your skin from natural UV radiation. In Victoria, it is illegal for solarium operators
to advertise their services as safe. It is also against the law to allow people under the age of 18 or
who have skin which burns and doesn’t tan to use these facilities.
Cancer Council Australia and the Australasian College of Dermatologists do not support tanning in
solariums in any circumstances.

Things to remember
• The desire for the appearance of tanned skin is still high, especially among younger
Australians.
• Most fake tanning lotions provide a safer way to change the tone of your skin but offer no
sun protection.
• The UV radiation emitted by solariums contributes to skin and eye damage and an
increased risk of skin cancer.
• Both sun and solarium tans are a sign your skin has been damaged by too much UV
radiation exposure.
