New Federal law on Sunscreen

This article summarizes the science behind the new law, here are some highlights:

  • zinc-oxide-on-nose_thumbSunscreen marketing cannot say waterproof or sweat-proof – I wonder why they could say that before if it wasn’t true.
  • “Broad Spectrum” is allowed for products shown to prevent sunburn (from UVA rays) and skin cancer/aging (UVB rays).
  • If it’s not effective against both kinds of rays, the label must say that it only prevents against sunburn and it does not protect against skin cancer/aging.

There are a lot of questions about sunscreens.  Which ingredients are more harmful than helpful?  Are the best products available in the US?  Are spray on sunscreens okay to use?  I don’t know these answers, and I don’t know the best source for information on these either.   The Environmental Working Group, rated 4 star on Charity Navigator, has some tips on these topics.
