Skin Safety Against Sunlight Some Key Considerations

Posted for Sun Tanning On September 14, 2009

Hi,

Safety against sunlight has been one of the major skin concerns among women. The importance of using sunscreen is known to everyone. However, what most people do not know is how to apply sunscreen correctly so that it protects the skin against the ill effects of the sun efficiently. In fact, how you apply the sunscreen is more important than the SPF number mentioned on the product!

The SPF or Sun Protection Factor of a sunscreen is how much time we can spend out in the sunwithout getting damaged by the sun\’s UV rays naturally. However, recent studies have found that a sunscreen labeled SPF 15 doesn\’t really mean you can stay in the sun 15 times longer than you could have without any sunscreen, but it is a good numerical value to use when considering the strength of a product.

More than the SPF is related to the time that can be spent out in the sun, it is related to the harmful ultraviolet radiations that penetrate the skins surface. Here are some key considerations while using sun screen products…

Sunscreens don\’t start working from the minute you apply them. Rather, they take about 30 minutes to get absorbed inside the skin surface and start the protection process. So make sure you apply your sunscreen at least 15-20 minutes before your venture out in the sun.

Apply sunscreen all over the exposed parts of your body including your back, neck, ears, arms and feet.

Always wear protective clothing that covers your skin. You can also carry an umbrella or wear SPF rated clothing.

SPF 15 blocks about 93 percent of the UV-B radiations that are responsible for causing sunburns. SPF 30 absorbs nearly 97 per cent of the rays and SPF 50, 98 percent of the same. Thus you can see the difference between the SPF numbers is very marginal 30, so that is usually a good number to shoot for.

Once you know the intricacies of sun safety, it becomes easier to protect your skin against the sun!
