How to Choose the Right
Sunscreen To Protect Your Skin from Overexposure to the Sun's Damaging
Rays This Summer.
(I suggest you print this article out and take it with you
when you go shopping for a sunscreen.)
Introduction
Researchers are warning that many sunscreens don't offer full protection from skin
cancer, especially the
deadly form called melanoma. They state that most commercially available,
sun-blocking lotions protect against ultraviolet B (UVB) see glossary) radiation, but
they generally do not contain agents that block the part of the solar spectrum called ultraviolet A
(UVA). UVB is firmly linked to the far more common, and less dangerous, forms of skin cancer,
squamous-cell and
basal-cell tumors.
However, new research studies show that 90 percent of sunlight's melanoma-causing effect may come from
UVA, and only 10 percent from UV-B. Even if you love the sun, the health consequences of
sun-worshipping have become more apparent in recent years: wrinkles, blotchy
complexion, leathery skin -- and skin cancer. The rise in skin cancers has been linked to lifestyle
changes over the past 40 years, such as skimpier bathing suits and clothing, more leisure time spent outdoors and migration
to the sunbelt.
Dangers of the sun's rays
Ultra-violet and infrared radiations can have harmful effects by altering the epidermis and dermal layer of the
skin. Direct exposure of skin to the sun, and therefore to UV radiations, set
off free radicals, (see glossary) which degrade cell structures. Effective protection against
harmful effects of the sun is now more critical than ever before. More people are living in
high-sunshine areas and are engaged in more outdoor recreational activities
than ever before. The incidence of skin cancer has risen steadily in the second half of the 20th Century. Your
sunscreen must create a protective barrier to shield you skin from the harmful effects of the sun.
How Sunscreens Should Give You That Protection
Properties of an effective sunscreen
The ideal sunscreen should incorporate six scientifically proven methods to provide the best protection possible
against the sun.
1. Uva-Uvb Absorption Sunscreens should contain ingredients that absorb the sun's damaging UV radiant
energy and also should absorb damaging rays that would normally go directly to your
skin.
2. Heat Dispersion Sunscreen formula should also disperse the sun's energy by using particles that scatter
light and reduce heat buildup.
3. Radiation Absorption It should contain products that have the ability to absorb harmful infrared radiation. This
minimizes heat buildup, reduces heat-generated free radicals, and helps
keep the skin cool.
4. Free-Radical Protection All of the sun's UVA, UVB, and IR (Infrared radiation) rays generate damaging free
radicals that result in premature aging and wrinkling. Your sunscreen should
contain natural herbal extracts that help to protect the lipid-rich cell membranes from
oxidation and free-radical damage.
5. Liposome Delivery System (This one is very technical, but important) Sunscreens should contain microscopic
liposomes that periodically release their contents directly into the skin.
Liposomes are minute sacs or bags of phospholipids containing botanical extracts of aloe
vera, green
tea, green coffee, and grape seed extract.
6. Restorative Properties Sunscreen should contain emollients that moisten, soften, and retard premature
skin aging. Herbal ingredients containing natural vitamins, minerals, and amino
acids, known to be effective in promoting healthy skin, should be included.
How to Choose A Sunscreen
Check the label for sunscreens that work against both UVA and UVB for more complete protection. You WANT
both! Then check out the level of protection: is it a 15 or 30 or 30+?
You will have a bit of a challenge finding all the above-mentioned ingredients. To my knowledge so far
only one company manufactures to those specifications. But check
carefully. If you can't find one that matches this one precisely, settle for one that has as many of
them as possible. Just make sure it does cover BOTH UVA and UVB. You need that
long-term protection.
Directions
Sunscreens can be used as an all-over skin protection or can spot-protect sun-sensitive areas such as the ears,
nose, scalp, and cheeks. They can be excellent moisturizers for all skin
types and help to promote healing of dry skin. Their non-irritating formula is safe for
sensitive facial skin and won't clog pores.
Because some are waterproof, rub proof, and sweat proof, you can maintain your skin's natural beauty while
out in the sun and enjoy every minute of it. Sunscreen should be liberally applied
to all exposed skin surfaces and reapplied periodically, particularly after swimming or
in periods of heavy perspiration. Apply sunscreen regularly, cover up exposed skin periodically,
and hang out in shady spots whenever possible. Apply it every morning or before exposure to sunlight. Apply it fifteen
minutes before going out in the sun and be generous with its application. Always limit your sun exposure
during the hottest hours of the day, particularly between 10 a.m. and 4 p.m
More Sun Care Pointers
The danger of skin cancer varies widely from one person to the next. Some people who burn easily are more
susceptible to skin-cell damage that can lead to cancer. While using top
quality sunscreens will help protect you, decreasing your overall exposure to the sun will
ultimately reduce its damaging effects.
Sunscreens do protect against sunburn and when used appropriately do reduce the risk of premature skin aging
but they are not a license to sit in the sun all day long without a hat and protective clothing.
Play it safe in the sun and don't stay too long in the heat as it causes your body to overheat.
Be sure to wear other forms of sun protection whenever appropriate.
Wear sunglasses with UVA and UVB protection, and
cover any exposed areas of skin as is practical.
Know that some medications make you more sun and heat-sensitive. This is called photosensitivity. (see
glossary).
Be kind to yourself. Follow these instructions for a relaxing, safe "time out".
A word of caution: babies under 6 months old should not wear sunscreens and they should be well protected from
strong, direct sunlight.
Glossary:
(The Mystery of SPF explained)
Sun Protection Factor (SPF)
All sunscreens are rated by the Sun Protection Factor listed on the label.
SPF numbers indicate how much protection from the sun the product will provide for your skin
SPF 15 & 30 are the recognized ways to identify sunscreens.
An SPF of 15 means that if you normally burn after 15 minutes of exposure to the sun, it would take 15 times longer (or 225)
before you would get a sunburn.
A higher SPF number doesn't mean a higher degree of UV protection: it means protection from the sun for a
longer period of time.
SPF 15 is for people who tan easily and quickly, or are exposed to sun for a moderate amount of time.
30+ SPF is for fair-skinned people and those who are out in the sun for extended periods of time..
It is recommended that everyone use a sunscreen with an SPF of at least 15. Those who burn more easily may
want to use a higher SPF such as 30 or more. Using two different products (such as
SPF 8 makeup and SPF sunscreen) does not give you additional sun protection.
You will only be protected according to the one SPF product with the higher number.
Photosensitivity: your body's increased sensitivity to the sun in reaction to some medications.
UV: Ultraviolet rays
UVA: These are ultraviolet rays that are now believed to be linked to skin cancer.
UVB: These rays are firmly linked to the far more common, and less dangerous, forms of skin cancer,
squamous-cell, and basal-cell tumors.
Free Radical: They are oxygen molecules that have at least one unpaired electron in their outer orbit. If they are
not neutralized quickly, they may create a lot of damage to different parts of the body. (That's a very, very basic
description.)
Sunblocks: If you are spending a long period of time on the
water or high on a mountain, sunblocks that completely block the suns/repel rays are worthwhile. The
usual type is a zinc oxide ointment that is applied to the nose and cheeks, which are
highly exposed to the sun. Some sunblock products are also now available as
lotions and may be referred to as "natural" sunscreens.
Sunscreens: These are lotions and creams that are rubbed onto the skin and provide protection from the
damaging effects of the sun.
Conclusion
It's hard to find anything more refreshing than playing on the beach or taking a walk in the park. But whether you
are water-skiing, swimming, or playing tennis and golf this summer, even though it's warm and beautiful
outside, it can also be dangerous for your skin if it's not protected correctly.
Some rays of the sun, such as ultra-violet and infrared radiations, can have harmful effects to the body by
altering the epidermis and dermal layer of the skin. When directly exposed to
the skin, these harmful rays can cause severe damage, accounting
for nearly 700,000 cases of skin cancer per year. So for sun
lovers it's
important to be aware of the health risks of not protecting your skin.
Wrinkles, a blotchy complexion, leathery skin, and one of the most hazardous problems-skin cancer, are only a few
of the dangers of getting too much sun.
Remember that sunscreens are just part of the sun protective system you should practice. Don't forget to
drink at least 8 glasses of water a day.
