I had high hopes for Keys Solar RX. I still haven't found a sunscreen that works for me. Devita's is nice, but I break out if I wear it for more than three consecutive days. So obsessed have I been in trying to find a sunscreen that I don't react badly to, I seemed to have forgotten about its real purpose: protection from the sun.

Keys Solar RX gave me a rude awakening. Almost literally. Last Saturday afternoon, I woke up from a snooze on the deck to find that my face was beetroot. And it wasn't particularly sunny - a weak orb, peering through a cloudy sky and chilly enough to be wearing a fleece. I had applied the Keys Solar to my forehead - I wanted to make sure that my skin didn't have an adverse reaction before subjecting my whole face to it. After an hour or so of napping, my forehead and cheeks were the same color - red.

Keys Solar claims to have a broad spectrum (UVB and UVA) SPF of 30+. It uses nano zinc oxide, which was controversial until very recently because of concerns that nano particles could be absorbed by the skin. In 2006, the Environmental Working Group gave nano zinc oxide the all clear after examining the evidence of 15 peer-reviewed studies on skin absorption, nearly all showing no absorption of small-scale zinc and titanium sunscreen ingredients through healthy skin.

I have tried this sunscreen a few times and I have had no adverse reaction to it. I like the fact that it has antioxidants and vitamins from shea, avocado and cumin, while the preservative is non-chemical, non-carcinogenic rosemary extract. What I don't like is that it doesn't offer as much protection as my pale and freckly skin needs. I think I'll be trying Arbella next.
