Wearing sunscreen is so important!! It protects you from the sun’s harmful rays reducing your risk for skin cancer, premature aging and sunburn.
Sunscreen protects your skin from the sun’s harmful UVA and UVB rays. Although almost 95% of UVA rays reach the earth’s surface and can cause skin damage, UVB are the bigger culprits in causing sunburn. UVA rays penetrate the skin more deeply causing wrinkling and sagging of the skin. They also enhance the harmful effects of UVB rays.
The redness, swelling and skin peeling of sunburn cause widespread damage to your skin cells. Sunburn that causes severe blistering can cause permanent damage to your skin cells increasing your risk for various types of skin cancer.
Choose a sunscreen that provides broad spectrum UV protection. Sunscreen should be applied at least 30 minutes before you go out in the sun and every 40 – 60 minutes while in the sun. Sunscreen doesn’t block harmful UV rays for more than 2 hours.
So…now that you’ve decided to wear sunscreen..off you go to the store..and there you have it…an aisle filled with shelves and shelves filled with sunscreen bottles of every shape and size. 🙁
Let’s look at some info that can help you decide which one to buy…..
SPF is short for Sun Protection Factor. To determine a sunscreen’s SPF, testers round up 20 sun-sensitive people and measure the amount of UV rays it takes them to burn without sunscreen. Then they redo the test with sunscreen. The “with sunscreen” number is divided by the “without sunscreen” number, and the result is rounded down to the nearest five. This is the SPF.
Minutes to burn without sunscreen x SPF number = maximum sun exposure time....in other words…if it takes 20 minutes for your unprotected skin to start getting red or beginning to burn…using SPF 15 should protect you for 15 times longer or about 5 hours.
Sunscreens with an SPF of 15 or higher usually do a great job protecting you against UVB. If you work outdoors or love the beach for hours on end…you should use a higher SPF and a sunscreen that is water resistant. The last thing you want is sunscreen running into your eyes while you are sweating from overexertion.
Sunscreens containing PABA have recently come under fire…I for one…have a sensitivity to PABA so I choose PABA free sunscreen. PABA or para-aminobenzoic acid acts as a dye that absorbs UVB rays. The most common side effect of PABA in sunscreen is an allergic reaction which is most likely a rash. Most sunscreens are PABA free…but you should read the label before purchasing one.
Choose a broad spectrum sunscreen offering protection against UVA & UVB rays…water resistant….with an SPF of 15 or higher…and enjoy your day out doors!!! 🙂
