I know I seem like I’m on a bit of a kick here, but it seems that my confusion about sunscreen has a basis.  According to the Enviornmental Working Group’s most recent research on the industry, there has been a product explosion over the past two years.  Thanks to pressure from the EWG, the number of sunsreens containing any of the 4 recommended UVA/UVB blockers jumped to 70% from just 29% last year.  Most notably, the number of sunscreens protecting from harmful UVA rays has more than doubled.  Their 2009 sunscreen guide has a best of list with comprehensive pros and cons on each sunsreen.
