People flock to beaches and spend hours soaking up
the rays, but the sun does more harm than good when it comes to our
skin. Tan skin actually represents damage to skin, not health. In
fact, the American Academy of Dermatology has stated that there
is no safe way to tan. Every person, no matter race or skin
coloring, sustains damage to their skin from too much exposure to
the sun, which may include age spots, wrinkles, freckles, skin
tearing, discolorations, premature aging signs and skin cancer. The
best way to take care of your skin is to protect it from the
sun.
Your Skin and the Sun
Melanin, the substance that gives skin its pigment, also acts as
a barrier to prevent UV rays from wreaking havoc on your skin. The
extra melanin produced in response to sun exposure is what makes
people look tan. However, your skin can only generate so much
melanin, so a sunburn occurs when the UV exposure exceeds the
amount of melanin your body can produce.
Why Sunscreens Matter
The sun emits two kinds of ultraviolet rays that damage our
skin, UVA and UVB rays. UVA rays, which account for about 95
percent of the ultraviolet radiation that reaches the earth, pierce
deep into the dermis and will cause age spots, wrinkles and skin
cancers. Because UVB rays tend to create more superficial damage,
these rays produce sunburns, cataracts and immune system
damage.
Applying a sunscreen protects your from these rays
because sunscreens actually absorb ultraviolet light so that it
does not reach the skin. A good sunscreen should have active
ingredients such as benzophenones, cinnamates, PABA or salicylates.
Working in a slightly different manner, sunblocks literally stop the
UV rays instead of absorbing them and generally contain titanium
oxide and zinc oxide.
No sunscreen can offer 100 percent protection, but any product with an SPF (Sun Protection Factor) should offer a decent level of protection. Always reapply sunscreen when you are outdoors, even if the product claims to be "waterproof" or "water resistant" because waterproof products only provide 80 minutes of protection in the water and water-resistant sunscreens only protect for 40 minutes. Infants under six months should not use sunscreen, so keep them covered and/or in the shade at all times.
Protecting Your Skin
To avoid long-term damage and keep skin looking healthy,
remember these tips:
If You Get a Sunburn
Within four to six hours after time in the sun, your skin will
turn red and develop a sunburn if you have spent too much time in
the sun. The full impact of the sunburn will appear within 12 to 24
hours. Most mild sunburns cause sore, red skin and peeling.
Treatment for this type of sunburn includes cold compresses, cool
baths, moisturizers and drinking lots of water.
For more serious burns, watch for blistering. Cover the blisters with gauze bandages and make sure not to rupture the sores because this could lead to infection. With any sunburn, but especially more severe cases, stay out of the sun until your skin has completely healed. In extreme cases, a physician may prescribe oral steroids for infection, as well as pain medications.
