The sun is still the center of confusion regarding its effects on
the skin. The sun radiates visible light, which gives us the color
we see; infrared light, which gives us the warmth we feel; and
ultraviolet light, which we cannot see.
When ultraviolet radiation
reaches the skin, some radiation is reflected away from the surface.
Some radiation is also absorbed and scattered into the tissue just
beneath the skin's surface. The skin’s living cells absorb a
proportion of this radiation. UV radiation absorbed by living cells
can result in damage to the skin, such as sunburn, aging of the skin
and skin cancer. However, vitamin D synthesis relies on UV radiation
and is essential for the body. Some scientists believe that vitamin
D prevents skin cancer.
So, does sun cause or prevent skin cancer?
Compounded on the questionable effects of sun on the skin
regarding skin cancer is the questionable safety of sunscreens. For
example, the reflectors titanium dioxide and zinc oxide in nano
particle size and almost all UV absorbers have been shown to have
adverse effects on the body.
Most kids rack up a lot of their lifetime sun exposure before age
18, so it's important that parents teach their children how to enjoy
fun in the sun safely. With the right precautions, you can greatly
reduce your child's chance of developing skin cancer.
So what precautions should we take to prevent skin cancer?
The key to effectively protect the skin from skin cancer is to
find a healthy balance between getting enough natural sunlight to
maximize vitamin D production and obtain optimal health, while at
the same time protecting the skin from damage that occurs from
overexposure to the sun.
The following precautions are recommended:
For infants under 6 months — Keep infants out of the sun and
especially avoid exposure to the sun in the hours between 10 a.m.
and 2 p.m., when UV rays are most intense. Dress infants in
lightweight long pants, long-sleeved shirts and brimmed hats that
shade the neck. The skin of babies is less mature compared with
adults, and infants have a higher ratio of surface area to body
weight than older children and adults. These factors mean that an
infant’s exposure to the chemicals in sunscreens (as discussed
above) may be much greater, increasing the risks of side effects
from the sunscreen. So, infants should not use sunscreens that
contain potentially toxic ingredients. Barrier sunscreen with
titanium or zinc oxide that is not micronized can be considered only
on areas prone to sun exposure. These sunscreens appear white on the
skin when used.
For infants 6
months or older — Avoid exposure to the sun during peak
hours and dress with protective clothing, a hat with brim and
sunglasses. Use a broad-spectrum sunscreen with SPF of at least
15. Use a sunscreen that contains non-micronized zinc or
titanium oxides. Avoid using products that combine sunscreen and
the insect repellent DEET.

- Teenagers — Encouraging teenagers to use sunscreens
is more effective by highlighting the effects of sunscreen
usage on the prevention of premature wrinkling and aging
rather than precaution of skin cancer. Highlighting
consequences to appearance rather than health appears to be
more effective with teenagers. The fact that teens are
motivated by beauty to use sunscreens limits their use of
non-micronized zinc and titanium oxides, as these sunscreens
are visible as white when applied to the skin.
Children get 80 percent of their lifetime sun exposure before the
age of 18, so protection is important. Teens and people below 40
years should use a broad-spectrum sunscreen with SPF of 30-50 and
use sun-smart protective clothing.
Generally skin cancers appear in adults over the age of 40.
Additional care is required at this stage. Recently a treatment for
skin cancers has been reported using natural BEC glycoalkaloids in a
cream, CuradermBEC5. Various scientific publications have reported
that when skin cancers were eliminated by this therapy, no
recurrences were evident histologically by biopsies over five years
Subsequently it was reported that BEC glycoalkaloids, when added
to a specific sunscreen formulation with a broad spectrum and SPF
30-plus, had many additional benefits and that this CurasolBEC
sunscreen could eliminate very early precancerous and cancerous
growths. Accordingly, CurasolBEC sunscreen as a preventive for skin
cancers is recommended for people of all ages, especially those over
