Kind of scary that there's no regulation or standards. Also didn't realize that many sunblocks didn't work on UVA, which is what causes wrinkles. I admit I thought that the SPF numbers were exponential and was really surprised to see how small of a difference there was between 30 and 15.
Thanks for the article, and I found that small difference between the SPF numbers enlightening. It sounds like I should go for a physical sunblock
This has confirmed my choice of a physical sunblock over a chemical one. It was quite a shock to read that there is no regulation on this in the US...
