Using sunscreen to prevent cancer? Might want to read those labels a little more closely.
http://www.organicconsumers.org/articles/article_20972.cfm
The latest target of concern is the use by sunscreen manufacturers of nanosized particles of titanium dioxide and zinc oxide. A new report based on several preliminary studies says these atom-sized additives have the potential to cause serious harm.
That follows last week's report that the Food and Drug Administration has known for a decade that almost half of the most popular sunscreens contain an ingredient that may actually accelerate the growth of skin cancer cells.
France, Germany, the U.K. and the European Parliament have moved rapidly to require everything from safety testing and mandatory labeling of nanoparticles to even the outright ban of these engineered chemical creations in many sunscreen and cosmetic products. Nothing of the kind is happening in the United States, Friends of the Earth says in a report issued today.
Or... well... hmmm...
And consumers are pretty much on their own when it comes to determining what's safe to slather on their skin. Labeling is often inadequate or inaccurate. And not even the Consumer Safety Protection Commission, which ensures the safety of the items that Americans buy, is stepping up for sunscreen shoppers.
After trying to find a sunscreen that did not contain known carcinogens we finally had to admit we lose and have not used sunscreen for several years. Mostly we build our sun time up so that we can withstand longer bouts of direct sun without burning, but due to our very high elevation in the South Western desert when we know that we will be spending uninterrupted hours in the sun we slather up with St. John's Wort Oil and wear wide brimmed hats.
Here's to being an informed consumer. Tell those companies that you and your children expect better.
Safe sunning!

Have you ever seen Lavera? They are from Europe.
I'll look into the SJW oil.
I've got about 25 minutes tops in direct sun. (that's pink on the cusp of red) I'm outdoors gardening year round, Oct-March without sunblock, come March the sunburns start. :( I don't have a better solution, I'd rather not spend days out of commission due to blistered up sunburn.
As I often say, "I don't believe in sunscreen. I believe in shade." Sunscreen wasn't invented until 1938, and wasn't widely available until the 1950s. What did homo sapiens do for the 200,000 years previous? They sat under a tree.
Thanks for the fyi. You look really fair skinned like I am. For me there is no such thing as "working my way up". I will just burn so I'm petrified to not use some kind of sun protection. Does St. John's wort oil really work for your fair skin and for how long? Tell me more.
Oh, and do you have an email? We are headed to the Taos/santa fe area next week and I was hoping you could point me in the direction of some reasonably priced camping/boondocking;)

Nice. I don't touch the stuff myself, but I didn't know about the St. Johns oil either. Would you mind sharing a little on that? I have the root at home, but not flowers. Is there a differnce in which one I should use for this? It'd be nice if the root would work... I have some in a jar of oil at home right now :)
Aimee, I'm really concerned about your sun protection methods. A few things:
1. No tan is a healthy tan, and building up a tan to prevent sunburn doesn't do anything to protect against UVA rays. (I don't have access to this journal online, but this seems like a pretty appropriate article: http://www.google.com/url?sa=t&source=web&cd=1&ved=0CBIQFjAA&url=http%3A%2F%2Fwww.ncbi.nlm.nih.gov%2Fpubmed%2F17332389&ei=Sm8JTMTbD4GBlAelw7mdDg&usg=AFQjCNF8S-ZNjraTHKSQflssHNXLN761Yw&sig2=__c7mJd3i4JyFv825QOUDw)
2. There is absolutely no scientific research to back up St John's Wort oil as a sunscreen substitute. SJW is sometimes taken as a homeopathic treatment for depression, but when it is taken orally, sensitivity to sun exposure is increased: https://docs.google.com/fileview?id=0B5CkAsOXOuMTMDMzMzczMDMtYjE4NS00OWExLTk5ZWYtNjU0MWUwZDBlZDli&hl=en
3. There is a very very small amount of research on topical use of St John's Wort. This paper: https://docs.google.com/fileview?id=0B5CkAsOXOuMTMjNhNjRmMDYtMzU0My00YWU1LTk3N2YtYmI1MzAxYmFhZjZh&hl=en discusses use as a curative for rashes, blisters, etc, but even for this purpose it has limited success. Additionally, this paper is from 2000 and says there's no previous similar research; I've scoured the literature pretty thoroughly through as many databases as I have access to and there's negligible research more recent than this with any additional information.
4. The only information I can find about St. John's Wort as a topical oil notes that it increases sensitivity to light and sun. This is a good roundup of info: http://altmedicine.about.com/od/stjohnswort/a/stjohnswort.htm
The only places I can find talking about St. John's Wort oil as an acceptable sunscreen are homeopathic medicine websites, and I haven't found any scientific citation on any of these showing why it's used this way.
I'm concerned because you are all fair-skinned with red hair in a high altitude and therefore more susceptible to UVA rays and burning. The likelihood of zinc causing cancer is so remote, and so much more so than any damage you could get from chemical-based sunscreens, let alone the damage from no sunscreen at all. Zinc may not be the perfect option, but it's much better than the alternatives, and isn't it worth it to protect your kids?
Whoops, my google docs won't share. Here are the papers I linked, in order:

Claire, it makes sense that SJW would be used as a homeopathic if it increases light sensitivity. Homeopathy always uses the agent causing illness to treat and activate the immune system. I don't know about SJW but I have had much success in the past with many homeopathic remedies. I don't think it is fair for us to completely throw the idea out the window because we haven't heard of it before.
Sandra Cope sells a sunscreen lotion that I've used before. She's an amazing woman, committed to health. You should check it out! http://www.sandracope.com/index.htm
I found this quote by Susan Weed, author of many herbal remedy books, she agrees that St John's Wort can be used as a sunscreen.
St. John's Wort Hypericum perforatum
(St.John's Wort Family)
"This beautiful perennial wildflower may be hated by sheep farmers, but herbalists adore it. The flowering tops are harvested after they begin to bloom (traditionally on Solstice, June 21) and prepared with alcohol, and with oil, to make two of the most useful remedies in my first aid kit. Tincture of St. Joan's wort not only lends one a sunny disposition, it reliably relieves muscle aches, is a powerful anti-viral, and is my first-choice treatment for those with shingles, sciatica, back pain, neuralgia, and headaches including migraines. The usual dose is 1 dropper full (1 ml) as frequently as needed. In extreme pain from a muscle spasm in my thigh, I used a dropper full every twenty minutes for two hours, or until the pain totally subsided. St. Joan's wort oil stops cold sores in their tracks and can even relieve genital herpes symptoms. I use it as a sunscreen. Contrary to popular belief, St. Joan's wort does not cause sun sensitivity - it prevents it. It even prevents burn from radiation therapy. Eases sore muscles, too." ~ Susun Weed
I have never believed in sunscreen. I just limit my time in the sun and built up a base.
I have also heard that titanium dioxide can make men sterile and has been found in some deodorants.
