How often is a person
allowed to tan?
Since 1986, the Food and Drug Administration guidelines suggest that 48
hours should pass between tanning sessions. Pigmentation and/or erythema
(sunburn) may not be fully visible for between 12-24 hours. Thus two tanning
sessions within this 24 hour period could cause an unintentional burn.
In general, maximum pigmentation can be built up gradually, following
the exposure schedule, in 8-10 tanning sessions.
Is it harmful to wear
contact lenses when tanning indoors?
There exists no known reason why contact lenses may not be worn while
tanning indoors. When the eyes are kept closed and proper protective eyewear
worn, UV light is blocked from penetrating the eye or lens. However, the
heat generated by indoor tanning equipment could cause the eye to dry
a bit, thereby making the lens uncomfortable. Just as one should moisturize
the skin after tanning, contact lens wearers may also use the eyedrops
recommended by his/her optometrist.
Why do some people itch
after tanning?
Itching and/or rashes may be linked to several unrelated causes, so it
is important to obtain a tanning history on each customer. Some people
are naturally photosensitive upon exposure to UV. Others are susceptible
to heat rashes, a cause totally unrelated to UV light.
Certain chemicals or ingredients found in
cosmetics, lotions, shampoos, and even the acrylic cleaner may cause itching
as well. Rashes caused by these products generally occur in localized
areas on which the products were applied. Customers should be advised
to tan with the skin as clean as possible. If discontinued use of a suspected
product does not inhibit the rash, a person should discontinue any exposure
to UV light until the condition subsides or see a physician.
Does tanning cause
melanoma, a fatal form of skin cancer?
There is no conclusive evidence which substantiates that malignant melanoma
is caused by gradual, moderate UV exposure. However, those who are predisposed
to develop melanoma due to hereditary factors may intensify this condition
with exposure to indoor or outdoor UV.
While some studies have suggested a link
between severe sunburn and malignant melanoma, there are other studies
available that prove an inverse relationship. In a study published in
the International Journal of Cancer in 1989 (known as the Western Canada
Melanoma Study), Canadian researchers found a significant inverse association
between melanoma and chronic or long-term occupational sun exposure in
men, with the lowest risk in those with maximum occupational exposure.
This may suggest that repeated exposure can be protective. Gradual, moderate
exposure is not believed to be a strong influential factor as melanoma
generally develops on those areas not normally exposed to UV light.
Can tanning cause wrinkles?
Excessive exposure, particularly to high intensity UVA, can destroy the
resilient fibers of the lower skin layer, thereby causing the top skin
layer to sag. Thus, elastosis or wrinkling appears. UVA, if not blocked
by pigmentation and skin thickening in the outer skin layer, can penetrate
to the dermis and destroy skin elasticity. Thus, if one makes the decision
to tan, it is recommended that a light source which contains both UVA
and UVB is used. Even if a person uses a sunscreen, if it does not block
both UVA and UVB, damage to the lower skin layer can still occur upon
overexposure.
May pregnant women tan
indoors?
There is no current scientific and/or biological reason why a pregnant
woman cannot tan indoors or outdoors. In fact, some researchers believe
the productions of vitamin D caused by exposure to UVB may be beneficial
to both the mother and fetus. However, there is some concern that the
heat build-up which inevitably occurs when tanning indoors and outdoors
may adversely affect some pregnant women, just as a sauna or jacuzzi might.
A pregnant woman may not be comfortable in the tanning equipment. Furthermore,
for liability reasons, it is recommended that pregnant women consult their
physician before tanning indoors or outdoors.
