I've tried the internal search engine many times in the past.  It just doesn't work and I am doing it right.  Maybe it's a compatibility issue of some kind.  If you can copy the info here, that would be nice.  

[Qowpel]

As I have been reading more, it seems that PPD is NOT a direct indication of how well something protects against UV. For example. I used the BASF calculator and my RAW elements sunscreen which is 23% non nano ZNO gives a PPD of roughly 8-9. Which would mean roughly 90-92% reflection/protection from UVA rays right?

 

Well, then there is Bioderma that claims a PPD of roughly 42 which would mean ALOT more protection right?...Well I am not sure this is the case......... Because EVA Victoria, I remember her stating the PPD usually refers mostly to the UVA range of 320-360 (which is higher energy shorter wavelength so it penetrates more shallow).. Whereas with my particular ZnO sunscreen I use, even with the lower PPD, apparently I can achieve even a PPD of 4 up to the 400 UVA range (which up around here, the 380-400 nm range we have less energy yet longer wavelengths that are deeper penetrating)............... My question is, I am so confused. My only goal is to prevent skin aging and there are so many confusing factors.........   I no don't know if I am missing out on a ton of protection from say, Bioderma's chemical formulation, OR if I am actually, regardless of the PPD factor, getting better protection in terms of long term skin aging, better protection from the ZnO............ I'm just trying to prevent this skin aging. Can some knowledgeable souls PLEASE help me put this issue to rest?

 

It is really pissing me off

Umm... it seems you answered your own question in what you wrote. Take Eva's advice. You cant go wrong either way from a high PPD Bioderma sunscreen or a high % non-nano zinc oxide sunscreen.

I'm sorry it is just annoying because thee is so much conflicting information. It is quite annoying. I mean I would definitely be concerned if my sunscreen was ted at 8-10 ppd, which my sunscreen which is 23% non nano zinc oxide. I mean that would be blocking a bit over 90% of UV rays, which in my opinion would allow a fairly significant amount let through

I like Badger for waterproof.  I think it is 30 spf.  It really is natural.  It is a health food store brand in the US. It uses zinc oxide.  

 

Zinc Oxide used in Badger is uncoated.

 

If possible, I will not to use it.

Excuse my ignorance but what does uncoated/coated mean in terms of zinc oxide and how is it dangerous? I'm a bit concerned because I've been using badger's zinc-oxide sunscreen for a year or two...

In short, apparently the risk for free radical formation increases with the use of uncoated zinc oxide. The ones from Raw Elements are coated 23% ZnO

Oh no! Gosh... Thank you for clarifying... Will be changing up my sunscreen asap! Does anyone know of any good non-nano coated ZnO sunscreens?

As I said, raw elements has even a tinted one, then your normal ghostly white, pale color of course. It is a good one..

Gotcha. Didn't realize that was a brand you were talking about but just more scientific terms. Will check out. Thanks!

[mustardseed41]

I'd not be concerned with the un-coated Badger sunscreen. I'd be more concerned it looks like crisco oil on your face.

I hate that sunscreen. Burnout is un-coated as well. As are many of the really good ones.

Mustardseed,

 

Which sunscreen are you using?
 

[JBForrester]

Wait, I'm a bit confused - if coated is so much better, why do most zinc oxide sunscreens zealously advertise that their sunscreen is uncoated? And where can I find a non-nano coated zinc oxide sunscreen? Qowpel - I tried looking up Raw Element sunscreen but nowhere do they say their sunscreen is coated. I really need to replace my badger sunscreen with something else. And yes, mustardseed I'd love to know what sunscreen you use as well!

don't worry I have spoken to them personally over the phone. it is

[mustardseed41]

I'm currently using Burnout for my face and Purple Prairie for my neck. If you've never tried these, I would strongly advise buying all 4 versions Burnout sells. They have a new one I've never tried. Say's for face and body on jar. Others come in a tube. Of course they all can be used for face and body. The Ocean Tested one holds up very well in hot weather.

 

I wear Purple Prairie when the weather is cooler. You won't find a better sunscreen for the money. High zinc % and excellent price per ounce. It is slightly more white on my face than Burnout. I'd say Burnout is the most popular high % zinc sunscreen on the 2 biggest skin forums.

[happy lemon]

Thanks Mustardseed.

 

I have used Eco Sensitive and Kids of Burnout but both of them leave a fair amount of white cast on my face; that said, I may try the new one - Face & Body - as many popele say it is as clear as Devita.

[Ben]

Burnout is so good that I think they must be cheating. It's what I use. I'm am suspicious though.

[mustardseed41]

I've always felt that if you don't see some white from your zinc sunscreen, there is reason to question how effective it is.

I used Devita in the past. Was the most clear zinc sunscreen I've ever used. I never liked how shiny it was though. I always felt "Is this shit really protecting my face"

I also read of people getting color while using it. But then again that could be said of any sunscreen with factors like amount of application, re-application, etc. It just seems that I read more issues with Devita. It had a very strong following. Maybe it still does. Yea give the Face & Body one from Burnout a try. Let us know how you like it.

[happy lemon]

"I've always felt that if you don't see some white from your zinc sunscreen, there is reason to question how effective it is......"

 

It is my thought too.

 

I have used Allie for 3 years which is a great sunscreen which can protect me very well even I spend 10 hours on the beach.  One thing I don't like it much is that it makes me look very shiny, although it is not greasy at all.

It is really pissing me off

What if you first put on the Bioderma chemical sunscreen and then put on the zinc oxide? Would that work to get the full protection and fill in the gaps?

Uncoated. I don't believe one is better than the other. If anything uncoated may be better.
