As we know, there is 3 kinds of UV rays: UVA (that penetrate the dermis and have long-term effect such as loss of elasticity, dark spots, premature aging, cancer), UVB (that penetrate the epidermis and cause the sun burn and cancer) and UVC (that are extremely destructive but thankfully all absorbed by the o-zone layer). It was long though that UVB was the most dangerous among UVA and UVB. It causes the skin to burn and possibly to flake after a sunburn (which is, by the way, a "collective suicide" of your skin cells, their very last resort of preventing the apparition of a cancer or other destructive consequences). It was also though to be the only cause of skin cancer. However, recent recerch has proven that UVA is equally (or even more) dangerous than UVB because is penetrates deeper into the skin, where more skin activities are taking place. UVA can lower immune system, decrease collagen and elastin production and cause the skin to age much faster. Therefore, it is important to look for UVA blocking ingredients in your everyday sunscreen. And to wear sunscreen everyday. Actually, research has proven that using SPF 15 daily was more effective at preventing aging than using a higher SPF once in a while.

I never really paid attention to what SPF meant, except to get the biggest number I could find and to re-apply according to the directions. I'm glad to see that many beauty websites (like this one) and companies are working so hard to educate people about too much sun exposure. I read at The Beauty Girl that Jergens is donating $1 to the Skin Cancer Foundation for every view of its video with Jane Krakowski to promote its self-tanning moisturizer. Good stuff. http://thebeautygirl.com/?p=3233 This was very interesting, thank you.

I never really did know what SPF truly meant. I will keep this in mind as I head out in the sun this summer. Hmm..this was an interesting article. I never really did know what SPF truly meant.
