Secrets of Youthful Skin

Like your other body organs,
your skin begins to slow down
its functions as you age. As
levels of estrogen and
progesterone decline, skin
becomes drier, thinner, and
secretes less oil. Circulation
decreases, and wrinkles appear
when collagen and elastin,
proteins in the skin that
provide elasticity, break down.
The rate of cell production and
turnover decreases, and cells
grow thicker and more tightly
packed together.

Common signs of aging skin include unevenness of skin texture and pigmentation,
wrinkles, and "age spots," the brown patches caused by accumulated sun damage
that appear on the face, chest, and the backs of the hands.
However, most of the skin changes that are blamed on aging are primarily the result
of long-term exposure to the sun's ultraviolet rays. Compare the skin on the
underside of your arm (which rarely is bared to the sun) to the skin on your face. If
your facial skin had never been exposed to the sun, it would probably not look much
different at age 50 than it did at when you were 20. Sun damages not only the top
layer of skin, but the underlying supportive layer of collagen and elastin as well,
which causes wrinkling and sagging.
Fortunately, it's never too late to begin improving the condition of your skin
because skin cells have the ability to repair at least some of the damage caused by
the sun's ultraviolet rays. Studies show that women who use a sunscreen daily
experience significant improvement in the condition of their skin after only six
months. Obviously, the degree of improvement is related to how much sun damage
you have incurred, but the important point is that avoiding further sun exposure will
help you have better-looking skin. Use a sunscreen with an SPF (sun protection
factor) of 15 or higher every day, even during the winter and on cloudy days, and
make sure that the sunscreen you are using blocks out both UVA and UVB rays. While
using an SPF 15 sunscreen allows you to stay out in the sun 15 times longer than you
normally would be able to without burning, the best way to prevent sun damage is
to avoid direct sun exposure when the sun's rays are the strongest, which is usually
between the hours of 10 A.M. and 3 P.M. If you are outdoors during those hours,
make an effort to stay in the shade as much as possible, and use physical barriers
such as tightly woven long-sleeved clothing, sunglasses, and a broad-brimmed hat.
