to clear the air about SPF
The associated press released a little snippet about sunblock being bad for you and "causing cancer". Totally not true. I first heard about it on Howard Stern when Robin was reading the news, and I nearly drove off the road as they were all chatting that they weren't going to wear sunblock anymore!!!
The issue at hand is that some sunblocks were found to not have as much UV-A protection as they claim to. UV-B protection is usually the SPF (sun protection factor) they are referring to. UV-A is most frequently the causative agents of some skin cancers. The environmental working group is just releasing 2010 Sunscreen Guide which they tested 1400 different sunscreens indepedently to test their validity of SPF claims.
Go check out their web site and see if your brand is listed as a good one, if not, then toss it and grab a brand that has UV-A and B protection!! PS- they also found that the SPF's greater than 30 (i.e. 55, 75, etc) don't have any more protection for UV-A than SPF 30, but more UV-B protection.
Enjoy the holiday weekend, and PLEASE put on sunblock!!! Just grab one that has UV-A protection too!!!
Yours in Good Health
