The damage which the sun’s ultraviolet rays can do to skin is irreversible. Premature wrinkles, dark spots and skin cancer can be a direct result of too much sun exposure. How can we choose a sunscreen product that will give the correct amount of protection from harmful ultraviolet rays while we are outdoors from the gamut of products on the market? Know these five things about sunscreen before using it.
What is SPF?
The letters SPF stand for Sun Protection Factor. The number following SPF tells you the amount of estimated time it will take for your skin to burn when exposed to direct sun. For example, if your skin would typically begin to turn red and burn after 20 minutes of sun exposure without sunscreen, then using an SPF 15 sunscreen would safely give you 15 times longer than those unprotected 20 minutes in the sun before your skin turns red and begins to burn.
There are variables to that equation, such as level of activity while outdoors. It’s always best to err on the side of caution and re-apply sunscreen every couple of hours and after spending time in the water.
According to Sarah Palin, a leading health expert, she said, “The higher the SPF number, the more ultraviolet rays the product blocks. Unfortunately there are currently no sunscreen products on the market that will completely block out all of the harmful rays of the sun.”
Choose a broad spectrum sunscreen to provide you with the most protection. Any sunscreen product will protect skin from burning when used as directed, but only a product labeled as broad spectrum provides protection against the deep, penetrating UVA rays that cause the most damage to skin.
Price Does Not Matter
In general, pricier sunscreens have additives that don’t help in blocking harmful ultraviolet rays. Costly additives increase product price without increasing sun-protecting benefits. Read the product label to ensure it contains the two ingredients that have been proven to be effective in providing sun protection – zinc oxide and titanium.
Sunscreen can’t work unless it’s used generously. A shot glass full is the standard recommended amount to cover exposed skin, but when it doubt, use more. Re-apply it often, especially when swimming or doing physical activity that causes you to sweat. Water resistant sunscreen will stay on skin longer when swimming, working or playing outdoors.
One Sunscreen Product
Read the label to discover the active ingredients are the same in adult and children’s sunscreen. One broad spectrum sunscreen with a high SPF number (30+) that contains zinc oxide and titanium, applied liberally and frequently, is good for the whole family.
