Zinc Oxide (40% or better). Vastly superior to and healthier than ordinary sunscreen.

Yeah, this really appeals to me b/c you go straight to the chemical compound and don't get hung up on like the branded product.
So just zinc oxide will work fine? I'm thinking of picking this up then

Ombrelle with Mexoryl, which is not sold in US of A for some reason. You can find Mexoryl in Neutrogena, I think.
In general, you have to check your ingredients to see if they block the complete UVA and UVB spectrum. Lots of materials only block a portion of the UBA or UVB spectrum. This table is very useful:

The most "green" and effective sun block is zinc oxide in NON-nano sized particles -- something about nano particles being bad for your body. All other chemicals have varying risks of giving you tits and cancer on their own, which I mostly ignore except for the worst.
Lot of sunscreens use Avobenzone (Parsol 1789), which for contact lens users like me is known to burn eyes. It doesn't burn right away, but on a hot summer day, the shit slowly flows into your eyes through sweat (and/or absorption?). If you're driving, having burning eyes and contact lenses that make it harder for tears to flush out yours eyes is very very dangerous.
I found a kids titanium dioxide hypoallergenic formula that doesn't make my eyes burn. Unfortunately, it looks pasty white on my skin -- a problem with non-nano titanium dioxide.
I think I put some on once, but I hated it and never wore any again. Stuff feels nasty.

Get a sunblock for your lips as well - Chapstick type tube with SPF 15-40 in it.
Forgot about that... I found one chaptstick with SPF 5 or 15 and it didn't block the entire spectrum (Burt's Bees). Being paranoid, I started putting regular sunscreen on my lips -- holy shit that tasted terrible. Then I just blew $10 on an Ombrelle stick of lip sunscreen. It has a neutral taste, SPF30 and should be full-spectrum coverage. However, the shit only lasted about a year with moderate use.
P.S. I remember there was something about the formulation of the Coppertone and Banana Boat formulations that turned me off from them. It was either Oxybenzone or Octocrylene (or something) -- they'll give you tits or something.
Oxybenzone. The fears are unfounded. Its safe.
Safeway's house brand, sport version works pretty well and is cheap. CVS also makes a decent sport version.
Here we go:
Octocrylene

Oxybenzone

I'll avoid it just to lean on the safe side since the Ombrelle I prefer doesn't have it. I'm sure they'll find some other ingredient's super toxic tomorrow though.
Might be some trial and error.
Physical blocks like zinc oxide and titanium dioxide ones are horrible for me. Always leave a white cast, even the better ones that supposedly don't.
Physical blocks feel heavier, and are not necessarily the best at blocking UVA rays anyways, at least not by themselves. I have very light olive skin, and things absorb differently for everyone, so YMMV.
Anyways, some good ones:
http://www.amazon.com/Roche-Posay-Anthelios-Dermo-pediatrics-Lotion/dp/B003N47350
Extremely high protection (PPD 39), cheap, physical + chemical. Bitch to wash off.
http://www.amazon.com/Eltamd-UV-Physical-SPF-85-Gram/dp/B0012XO2W6
Good enough protection (PPD 8.6), physical only, lighter and less greasy than the above, though still difficult to wash off.
http://www.amazon.com/Eltamd-Clear-SPF-48-Gram-1-7/dp/B002MSN3QQ
Reasonable protection (PPD 5.8), physical + chemical, among lightest, non-greasiest of sunscreens with physical blocks.
In the end I prefer the neutrogena dry touch sunscreens, or the liquid ultra-sheer line. I apply them, and they absorb nicesly. PPD ranges from 4 to 14 depending on the amount of SPF they claim, so good UVA protection. Also photostable unlike most chemical sunscreens out there.
