Excessive
over exposure to the sun can cause changes in the skin's collagen
called photoaging. These changes can take the form of wrinkles
and fine lines, decreased skin elasticity (sagging skin),
or a thickened skin textured. UV radiation can damage the
collagen that supports the walls of the skin's blood vessels,
causing them to be more fragile. A symptom of this is easy
bruising on sun-exposed areas such as the back of hands.
Over the years, repeated sunburns and unprotected exposure
to the sun can increase the risk of skin cancers including
basal cell and malignant melanoma and other types of skin
cancers..
Prevention is the key to avoiding photoaging and more serious
skin damage. Here are some ways you can protect your skin
from the harmful UV rays:
ALWAYS apply a sunscreen before you go outdoors, especially
to your face, neck and hands. That means 365 days a year,
rain, shine or clouds. Choose a sunscreen that has a sun protection
factor (SPF) of 15 or more, with a broad spectrum of protection
against both UV-A and UV-B rays.
Use a sunblock on your lips, preferably with an SPF of 20
or above.
Wear
sunglasses with UV-A and UV-B light protection.
Wear long pants, a shirt with long sleeves and a hat with
a wide brim.
Limit your time outdoors when the sun is at its highest (about
10 a.m. to 3 p.m.)
Certain medications such as antibiotics can increase your
vulnerability to sunburn. Check with your doctor.
What to do if you think you already have skin damage?
Be sure to see your doctor immediately if you have any unusual
looking moles or changes in your skin. Don't wait.
You may be able to improve the appearance of moderately sun
damaged skin with alpha-hydroxy acids, which remove dead skin
cells from the out layers of your skin, leaving it softer
and smoother. Chemical peels, laser resurfacing or microdermabrasion
may also be helpful.
