THE SUN: YOUR BEST
FRIEND OR YOUR WORST
ENEMY? Sunshine gives us vitamins C and D, improves acne, and in general makes everyone feel better, more energetic. But, too much of a good thing can be bad for you. Statistics from The American Cancer Society show that most of the 300,000 cases of skin cancer reported each year are caused by overexposure to the sun, and that overexposure usually begins in the teen years.
That healthy-looking tan may look great, but what it really means is that your skin has already been damaged. Dr. Frank Krakowski, medical director of Johnson & Johnson Baby Products Company, warns: "The hardest thing to keep in mind is that the damage caused by overexposure to the sun begins long before it can be seen." Ultraviolet rays penetrate the skin, breaking down collagen and other components that give skin its elasticity. The damage these rays cause is cumulative and irreversible.
That's the bad news. The good news is that you can protect your skin from these harmful rays and look great. Dr. Karen Burke, a New York-based dermatologist whose special interest lies in developing anti-aging techniques, suggests that you know your skin type and tanning history, and use a sunscreen with a sun-protection factor (SPF) suited to you. (See chart below.)
How does the sun-protection factor work? It acts as a measure to determine how long you can stay in the sun before you start to burn. For example, if you start to burn after being in the sun for 10 minutes, using a sunscreen with an SPF of 15 will let you stay in the sun for 150 minutes (2-1/2 hours). Remember that no sunscreen will protect you from sunburn longer than the calculated time (normal burning time x suncreen's SPF). If your exposure exceeds this time, you'll burn!
