Sun
Damage Facts
- Daily exposure to the sun
over a lifetime is a major cause of skin damage, including
wrinkling and skin cancer.
- Any tan indicates skin
damage. The deeper the color of the tan the more extensive
the skin damage.
- Sunscreens with high SPF
numbers may provide less than full protection, because
SPF addresses only the UVB spectrum.
- Sunlight coming through
a window can damage your skin.
- Every year, more than 1,000,000
people in the United States get skin cancer. It is the
most common form of cancer, with rates growing three
to five percent annually. Left untreated, skin cancer
may be life threatening.
Common
Misconceptions
-
A products’ SPF
number is not a true determination of a sunscreen’s
capability of protecting the skin from the suns harmful
rays. SPF is only an indication of protection from
one wavelength of Ultraviolet light, the UVB (290nm-320nm).
This wavelength accounts for about 10% of the Ultraviolet
light that reaches the earth’s surface, and when
it comes to our skin, it is the cause of the early
redness experienced during sun exposure.
-
The statement
that an SPF of 45 is not that much better than an SPF
of 30, maybe or may not be true, since SPF addresses
only the UVB wavelength. SPF allows for no interpretation
of the products’ UVA protection capability, It
should be noted that until quite recently UVA was thought
to be harmless, our current rating system of SPF numbers
addressed only UVB.
-
No official
rating system yet exists for UVA protection. So, even
if you use a high SPF number sunscreen, you may still
be vulnerable to skin damage from the sun’s UVA
rays.
