I looked for the carrot seed oil thread (using Google, since it can be better than our internal search) back when I first saw Paul's post this morning, hoping I could drop a fast helpful link. Instead I found a mommy blogger (I don't use this term derisively) who tried to track down the carrot seed oil question in order to find out if it would protect her pale babies. She makes a very convincing case here -- although I think she overstates her research by calling it a busted myth -- that the widely circulated stories of carrot seed oil having significant SPF all come from a single study out of India, which she links, studies, and analyzes. The study, she says, did not look at that oil as an isolated ingredient; rather it considered a complicated mixed Ayurvedic sunscreen preparation full of difficult-to-parse ingredients in addition to the carrot oil. One of the other ingredients in the product turned out to be "yashad bhasm" which, she found out, is nothing other than our old friend zinc oxide.
One of my side hustles involves doing this kind of web research, trying to track down the origins of widely-repeated "facts" that are hard to source. I can't say this lady got it right, but her work has the ring of honest effort to it, and I find her analysis credible. I have not, however, attempted to reproduce her work.

I don't know that a UV camera alone proves very much about SPF. Did they determine a better test at the end of that video? Is that where they confirmed raspberry seed oil and aloe vera (whole unfiltered juice)? At least in the HTME video you see the raspberry seed oil actually being pressed and not distilled, so you see that is an oil and not an essential oil.

I thought it was a little odd that she was debunking a myth based on folks confusing the carrot seed oil with a carrot seed essential oil. That doesn't mean actual carrot seed oil (which is not the distilled essential oil) isn't effective.
Jocelyn Campbell wrote:It sounds like a UV meter test on just the carrot seed oil, as I think it was done for the raspberry seed oil, is what might be needed!
I use astaxanthin, which is an oral supplement whose side effect is you are MUCH less likely to burn. I usually burn VERY easily/quickly. But with astaxanthin I only burn after a long time and only if I'm in a tropical place. Never in WA.
The young economist looks down and sees a $20 bill on the street and says, “Hey, look a twenty-dollar bill!”
Without even looking, his older and wiser colleague replies, “Nonsense. If there had been a twenty-dollar lying on the street, someone would have already picked it up by now.”
