Awesome new sunblock for face: Neutrogena Ultra Sheer liquid, SPF 70. I bought it at CVS for $8, regularly $14. It's very, very sheer and seems to absorb quickly, and doesn't run into your eyes (yay!)
It's relatively new, bottle is a little on the small side, but you only use about a dime-size for your face. I use about the same amount for my neck and chest and whatever's left on the backs of my hands. I also bought an SPF 100 spray for my kids.
 
Not to burst your bubble- but I have heard that pretty much anything over either 30 or 45 doesn't make a difference.....except maybe in price....I will look for the article - Consumer Reports just did one on the best sunscreens.......

http://www.msnbc.msn.com/id/37319591/ns/health-skin_and_beauty/

The top 4 sunscreens rated by Consumer Reports, based on how well they protected against UVA and UVB rays while worn on volunteers who soaked in water for 40 or 80 minutes.

— Up & Up Sport Continuous (Target) spray SPF 30
— Walgreens Sport Continous spray SPF 50
— Banana Boat Sport Performance Continuous spray SPF 30
— Aveeno Continuous Protection spray SPF 50
And the lowest scoring sunscreens:

— La Roche-Posay Anthelios 40 with Mexoryl SX crea SPF 40 ($18.82 per ounce)
— Avon Skin-So-Soft Bug Guard Plus IR3535 Expedition pump spray SPF 30 (Doesn't block UVA rays)
— Burt's Bees Chemical-Free with Hemp Seed Oil lotion SPF 30 (Doesn't block entire UVA spectrum)

They make the Ultra Sheer in SPF 55 too, I get so blotchy from the sun I figured I should get the 70. (they were the same price)

From skincancer.org
Q. Many people mistakenly believe that an SPF 30 rating gives twice as much sun protection as an SPF 15 and an SPF 50 more than three times that much. What is really the difference?

A. In vitro tests have shown that SPF 15 sunscreens filter out 93% of UVB rays, while SPF 30 protects against 97% and SPF 50 98%.

Q. How does photosensitivity add to the risk?

A. Phototoxicity can result when a person uses one or another of a wide range of photosensitizing products and then is exposed to UVR. Typically, hours after the exposure the initial reaction, resembling a severe sunburn, appears. Many of the sensitizing agents are drugs, such as the antibiotics tetracycline, doxycycline and ciprofloxacin; the nonsteroidal anti-inflammatory ibuprofen; and the diuretic furosemide, as well as retinoids. Photoallergy, like other allergies, occurs in previously sensitized individuals. Repeat exposure to the same allergen plus UVR exposure prompts a typical pruritic and eczematous reaction. In some individuals, even certain sunscreen ingredients cause photoallergy; these people should switch sunscreens. [See Table 1.]

Anyone with a known history of photosensitivity should stay out of the sun as much as possible and rigorously use sunscreen and other sun-protective measures.

Photoprotection is also advised for patients with photo-aggravated diseases such as lupus erythematosus or dermatomyositis.
