Could you suggest the sunscreens that you are currently using? I have avoided the sun for most of my 50 years due to some bad experiences with sun poisoning as a child and in my early 20's. However if I want to ride I can't avoid the sun any more I currently have Coppertone Sport 50 Ultra Sweatproof sunscreen - but I do wonder about the chemical content. My skin isn't used to anything like this...

I am very fair, and also am of Eastern European ancestry (and Scot - but I take after my father's family where my complexion is concerned).
My current fave is "BestBloc" organic uva/uvb spf 15 from Best on Earth. It is really good, feels very light, no zinc oxide, and bloody expensive (but at this point my skin is definitely worth it).

Another good one is Sun Shield by MyChelle (you can get at Whole Foods). Also bloody expensive (even more per ounce than Best on Earth), and it uses a form of zinc oxide that does not turn your skin white. It is thicker. I believe it is SPF20 or so.

mraguirre's recommendations look intriguing to me if you want a higher SPF or water resistance.

mraguirre: what is a "physical" sun screen? Curious.

I too am very cautious at this point, esp as I was fried to a crisp repeatedly as a child through my mid 20's, and have always lived at high altitude. I could be a poster child for high risk for skin cancer based on genetics and lifestyle (and both of my parents have had a lot of cancers removed, and i've already had half a dozen or so), so I don't mess around anymore.
