Summertime… So many outdoor activities, so little time! We look forward to long, carefree days playing in the sun, be it a picnic, trip to the lake, or just lounging by the pool. Whatever you do, make sure you protect your skin.
Don’t leave home without adequate sun protection! According to the American Academy of Dermatology, more than one million new cases of skin cancer will be diagnosed in the United States this year. Melanoma, the deadliest form of skin cancer, will kill 7,910 people - that's nearly one person dying of melanoma every hour. Everyone is at risk, particularly infants and children, because of their thin, sensitive skin. Dermatologists recommend keeping infants out of the sun, and providing sunscreen for children six months or older; applied to areas not likely to be inadvertently put into their mouths, or that can drip into their eyes. But before you run out and buy the first product you see, you should know a few things.
There are actually two types of sun protection products: Sunscreen and Sunblock. Manufacturers of many of these products use the term "sunscreen" synonymously, but there are differences. Sunscreens are classified as chemical, while sunblock is physical. Sunscreens actually absorb the ultraviolet radiation, which reduces the amount of radiation that penetrates the skin. Sunblock, as the name implies, physically blocks both UVA and UVB radiation from the skin. Sunblocks used to be thick, white, greasy creams made of either titanium oxide or zinc oxide (you know, that lifeguard white), but thank goodness they have evolved and become much more user friendly. Whichever you choose, make sure it is waterproof.
What's a SPF?
Sunblocks and sunscreens are rated with SPF numbers or "Sun Protection Factor". SPF numbers are measured by timing how long skin covered with sunscreen takes to burn compared to uncovered skin. The higher the SPF, the more sunburn protection it gives. For example, SPF 15 means it will take 15 times longer to burn when wearing the sunscreen. Be aware that SPF factors only look at burning times, so they only apply to UVB rays. Up until this past year, we’ve pretty much been short-changed in adequate UVA protection.
What’s the difference in UVA and UVB radiation?
UVB radiation is the kind that causes sunburn. UVB waves travel at short frequencies, and don't penetrate beyond the skin's outer surface. It is very easy to tell who has had overexposure to UVB – they will either be burned or tanned. UVA radiation travels in long waves that skip merrily past the skin's surface and heads straight for the collagen that gives skin its elasticity. UVA damage isn't immediately visible, but takes a long-term toll on the skin. UVA exposure is the prime suspect in premature aging. What is worse is that scientists now believe UVA rays alter skin cells' DNA, causing mutations that can, like changes wrought by UVB, lead to cancer.
Thankfully, the FDA approved a new ingredient called Mexoryl SX, patented by none other than L’Oreal. In a nutshell, this ingredient has shown to be the most effective organic UVA filter, with very high photostability – meaning it will not degrade as fast, thus providing longer, more effective UVA protection. It is being marketed in the U.S. in a product called "Anthelios SX". It is becoming more widely available, but if you can’t find it in your town, Google it. SPF’s range from 15 to 60, and the average price is around $29.
Sun protection doesn’t have to stop with sunscreens and sunblock. Cosmetics are a wonderful way to maximize your time, money and sun protection. Cosmetics formulated with titanium and zinc oxides go a long way towards everyday sun care.
