Jennifer and others,

This is a relatively short and well written article on what we know and don't know regarding sunscreens.  It reports on  articles from JAMA and others.  I enjoyed it and found it not only refreshing, but informative.

Sunscreen Prevents Cancer, Right? Well, It's Complicated.

from the MD Anderson Cancer Center website:
“Choose a sunscreen that’s at least SPF 30, broad spectrum, and water-resistant if you’re swimming or sweating,” George says. “Beyond that, with all the brands and formulations out there, pick whichever one you like that you won’t mind using regularly.”

It isn't just SPF but also broad spectrum, to block UVA and UVB rays.  Again, from the website above: "There are two kinds of UV rays – UVA and UVB. Each penetrates your skin differently. The SPF rating only refers to UVB rays."

Some info I saw said the current FDA rules are outdated; a new set seems to be in the works.  Euro rules are stricter, so looking for a product that meets those rules might be a good approach too.

I usually use a sheer or ultralight, broad spectrum sunscreen because it seems to interfere less with sweating.  Like CeraVe or Neutrogena, in a SPF30.  


 https://www.ewg.org/sunscreen/  address your toxicity concern a bit Hawke, but they have so many choices it was kinda overwhelming.  Plus I couldn't find much on the toxicity concerns past that they were identified.

I would like to probe the New Mexico cycling hive mind about sunscreen. I have used bullfrog for years, but am a bit concerned about it being somewhat toxic. I find with zinc oxide only sunscreens I tend to wipe them off getting sweat out of my eyes, and then get sunburned anyway. I got some chemical and zinc oxide sunscreen from Target and it seems to interfere with the sweating/cooling process. Do you have a favorite you might recommend?

Thanks
