The
Sun
Tanning , the right way!
There's no doubt that most of us feel better when the sun
shines. Sunlight heals and strengthens our bodies, and is an
important source of vitamin D - essential for healthy nails,
teeth and bones.
Most of us look better, too, with the golden glow of a
tan. But this short term beauty
bonus has to be offset against the long term effects of
over-exposure to the sun. They do not show up immediately and
by the time they do become obvious, it's too late to do
anything about them. So always give your skin extra care and
attention in the sun.
Is brown beautiful?
Less than a hundred years ago, and for centuries before that, a
tan was considered vulgar! A pale skin was every woman's ideal
as it showed that she didn't have to work out of doors.
Fashions changed, however, and recently a tan has become an
important
beauty 'accessory'. Although today a tan is still seen by many
as an enviable beauty feature, dermatologists now agree that
overexposure to the sun is in fact harmful to the skin and is
a prime cause of premature ageing.
What happens when you tan?
A suntan is actually a protective mechanism within the skin.
Melanin - the substance which determines the skin colour - is
produced when certain cells in the epidermis are exposed to
ultra-violet rays from the sun. When these cells reach the
surface, they appear as a tan, which is the skin's protection
against burning.
Burning is the most obvious risk from overexposure to the sun,
though with care sunburn can be avoided. Another danger is
increased dryness and a thickening and coarsening of the skin.
But the greatest
damage occurs in the lower layer of the skin -the dermis.
Unlike the epidermis, this layer does not renew itself and any
damage done will therefore be permanent. Within the dermis is a
network of fibres which cushion and support the skin. The sun's
rays which penetrate the dermis break down these fibres and
make them slack. As a result, the skin becomes less firm and
less supple and lines and wrinkles start to appear on the
surface. This deep damage is invisible at the time it is caused
but becomes more obvious in the long run.
The right way to tan
Whatever the risks may be, the fact remains that many of us
still want to acquire a tan, so it makes sense to proceed with
care when in the sun.
Just how brown you become depends on your natural colouring, as
this indicates how much melanin you have in your body. As
melanin is the pigment which determines the colour of your hair
and eyes as well as the colour of your skin, all three together
provide a good guide to your personal 'tan-ability'. If you
have olive skin, with dark hair and eyes, then you'll tan more
easily and more deeply than if your skin and hair are fair and
your eyes blue. If you are a light-eyed, fair-skinned,
freckle-faced redhead, however, then you probably won't tan at
all - but you should take extra care to prevent yourself
burning.
Another important factor to be aware of is your skin's
sun-tolerance - that is, how long you can safely stay in the
sun without burning. Knowing this will help you to calculate
your own 'tanning timetable', and
to choose sun tan preparations with the right sun protection
factor for your needs.
Timing is all important. The time of day determines the
strength of the sun; it is strongest between 11 am and 3 pm and
the burning rays are at their most intense between these hours.
In the earlier and later parts of the day the sun is weaker and
the risk of burning is reduced. The safest times of all are
before 8 am and after 4 pm.
The time of year counts too. Obviously, the sun is stronger in
summer, as it is nearer to the earth. It's important to
remember, though, that summer comes sooner in some holiday
locations. The nearer you are to the equator, the stronger the
sun - and the greater the risk of burning. There is also more
risk of burning at a very high altitude -even on a winter
holiday, when the snow reflects and intensifies the sun's rays.
Reflection also occurs from sand and water, and even from
bright white walls. All these factors increase the strength and
intensity of the ultra-violet rays.
It is often thought - wrongly - that you will only tan or
indeed burn when you can see the sun shining. Unfortunately,
this is not true at all - the ultra-violet rays are still
around even on hazy or overcast days, so can still produce a
tan or even sunburn. And a light breeze, although it may make
you feel cooler and more comfortable, is no protection at all
against the sun.
So, always aim to tan gradually. This not only reduces the risk
of burning, it also produces a tan which will last longer. It
takes about 8 days to develop enough of a tan to protect you
against sunburn. Begin with a very short period of exposure. If
you are fair-skinned start with 10 or at the most 20 minutes on
each side of your body - front and back. If you are darker, you
can start with up to 25 minutes front and back. If your first
exposure causes no discomfort or reddening, then you can
increase the time by about one third each day. Remember to
count in all the time that you spend in the sun as exposure
time. You may not be trying to get a tan when you walk along
the road to the beach, but your skin won't know the
difference!
After the sun
When your skin has been soaking up the sun all day, it's liable
to feel tight and dry. And, of course, it will be dry because
the sun is dehydrating. Put back some of the lost moisture, and
soothe and lubricate your skin with an after-sun lotion.
Applied lavishly after every tanning session, this will not
only keep your skin soft and smooth, but also help you to hang
on to your tan just a little bit
longer. As the top layer of dead skin cells are shed, so too is
your tan. You won't notice this if the sun continues to shine,
as you'll keep right on tanning; but when the sun has gone, or
when summer's over, your tan will gradually fade away. Dry skin
flakes off more readily and more rapidly than skin that's kept
moist and supple - so regular moisturising lets your tan last
longer.
Always apply after-sun lotion or moisturiser after
sunbathing
Faking it!
If you can't or don't want to tan, but like the effect of
tanned skin - then a fake tanning product is the answer for
you.
These products contain a chemical substance which reacts with
proteins in the skin's outer layer to produce a tanned effect
-usually within 3 to 5 hours. Though the result differs from a
real tan in that the process does not involve melanin
production, it will last about the same length of time as a
naturally-acquired tan (about 8 days) and will fade gradually
just as a real tan does.
Fake tanners usually come in the form of a lotion or a foam.
Great care must be taken when applying either type to avoid
streaking and patchiness and to achieve a natural-looking
result. It's important to start with clean and well-moisturised
skin. Apply the foam or lotion as smoothly and evenly as you
can - a fine sponge makes an excellent applicator. Use long,
smooth strokes rather than dabbing movements and don't attempt
to rub the foam or lotion into your skin, it should just be
spread over the surface. Dry areas of skin will take much more
colour from the product than moister, smooth skin, so you
should apply it very thinly indeed to rough patches on elbows,
knees and heels. Some fake tanning products also incorporate a
cosmetic colouring agent so that you can see where and how well
you have applied it. Wash your hands well afterwards, or they
will be stained very darkly indeed when the colour develops.
Remember, it's better to apply too little, as you can always
repeat the process for a deeper colour, than to overdo it and
have to wait some time for the effect to fade.
If you want to build up a natural-looking tan (perhaps in
preparation for your holiday) using a fake-tanning product,
apply it every
other day for a week. If you want to wear a fake tan all the
time, then keep it going with weekly applications.
You can also fake a tan with cosmetics which stain or colour
the skin like make-up, rather than by a chemical reaction.
Their effect is temporary and will wash off with soap and
water.
Caution: Remember, when wearing a fake tan of any kind, that
these products do not as a rule contain any sunscreening agents
(the label will tell you if they do) so they give your skin no
protection against burning. If you go out in the sun, always
apply a protective sun care preparation over your fake tan.
