Here is some info:

http://voices.yahoo.com/rice-bran-oil-as-natural-sunscreen-7337600.html?cat=5
I'm really concerned about any type of chemical and natural sunscreen active ingredient, specially the cell oxidation rumors on some active ingredients like zinc oxide or titanium dioxide, also chemicals mexoryl, avobenzone...etc...I just don't want secondary effects in health or skin. I'm looking for the purest and non harmful form of sun protection and Rice Bran Oil seems to cover most of sunblock needs as well as avoiding tanning?
Please help and advice on this topic. I'd like to clear aby doubts before purchasing Rice Bran Oil and testing my skin reaction, my main concern is free radicals and skin tanning. It seems Rice Bran Oil blocks the cell melanin production in the skin.
Thank You. |

I would careful about doing this.
Also, the second site has user-submitted content. |

Those oils/extracts that claim to offer UV protection do really work (sesame, soybean, raspberry and a couple others). Almost. They have a catch there though. They are protecting skin from the UVB range at best of times (far from broad spectrum) and depending on the season, extraction and processing methods and other details. Very difficult to determine the exact SPF (if there is one) without testing each batch.
Most benefit you can expect from oils like rice bran is in form of the antioxidant constituents who work same way like any store bought antioxidant serum, provided there is a decent concentration of phenols, carotenoides, glycosides, or whatever else constituents.
Means they don`t provide UV protection per se, but help counteract the effects of UV damage within skin. There is a good reason why these constituents are extracted and used in higher concentration in skin care products, to benefit from gamma oryzanol one would have to use crude rice bran oil (has ~2% γ-oryzanol) and it`s a dark brown greasy substance. Easier to just buy some powdered extract and adding to moisturizer at twice the concentration without the excess oil. And then using a decent sunscreen on top.  |

| I've stopped using the so called natural sunscreens with titanium dioxide because they ruined my clothes. White stains that won't come out. I'm sticking the Clinique City Block for my face and Neutrogena Ultra Sheer or whatever it's called dry touch for my body. |

I think I'm going to switch from physical to chemical sunblocks because I found out that zinc oxide can deteriorate your cell DNA...plus I found a good sunscreen that is suppose to prevent tanning of my skin.
Not really sure about the DNA damage though... |

From where did you hear that? |

 m, that is interesting. I know chemical sunscreens generate free radicals so if zinc does too, then I guess they are equal in that issue. Unless one generates more vs the other kind.
Not sure what to think about the lung tissue soaked in nano zinc. I don't soak my skin in zinc and never inside my lungs! |

| All these scientists and investigations are making me crazy! I wonder if it's a battle between interests?? |

I'm not sure you will ever have a definitive answer. New studies are always being done and science changes as it learns new things. The thing I don't like about this study is that it is done on human lung cells that are immersed in a solution of nano particles of zinc oxide. We as consumers do not put sunscreen on the cells of our lungs that are inside our bodies. We put it on our skin and to me that is a BIG difference. Also it doesn't mention how much zinc is in the solution or how much cell deterioration happens to the control group and all kinds of other things. My personal belief is that we are better off using sunscreen then not and what ever kind you buy should be something you are willing to wear because if you don't like how it feels, color etc. you aren't going to use it. |

my first thought was of the studies I read referencing spray-on sunscreens and their negative effects due to the potential of inhaling the particles
but after skimming the above link
it seems now even a mineral-based topical sunscreen must have sufficient antioxidants to counter the effects of radical-producing zinc-oxide
CookieD, you're right,
scientific research on sunscreens is always on-going and it's vexing to try to keep up... |

| I was unimpressed with rice bran oil. I doubt you will get any appreciable SPF from it that could replace sunscreen. Maybe with seabuckthorn berry oil or other potent oils, you could get an SPF of 2-4, but that's not enough to day out in the sun much longer. |

I agree with all this^ so much, you wouldn't believe it even if I began to explain why. 
There are such an overwhelming amount of studies done on the positive effects of topical zinc oxide. It's enough to make your head spin; seriously! There's no reason to fret over only one study, especially one performed ex vivo. If it's safe enough for a baby's skin that's good enough for me! (Granted, very young skin has a greater affinity for alkaline ingredients. But still.)
As far as using rbo as a sunscreen...I will also have to ditto what has already been said. There is no way an organic all-natural ingredient will ever have a consistent spf from batch to batch, and it's a bad idea to use it for sunscreen/sunblocking purposes. If you want to use rbo to help augment a real spf, then do that instead!
Besides, I thought red raspberry seed oil was supposed to have the most potential as a stand alone sunscreen. Did that get thrown out the window when I wasn't looking? |
