This is an area I've looked into a bit lately. The sad truth is many sunscreens aren't nearly as good as you might think from their SPF rating. Many sunscreen ingredients break down in the sun, in a matter of minutes or hours, and then let UV radiation through to the skin
There are two different types of UV rays in sunlight: UVB light causes surface sunburn, while UVA light penetrates and causes deeper connective tissue damage -- even when the skin surface feels cool.
SPF 15 blocks 93% of rays, while SPF 30 blocks 97%. Experts say that SPF ratings higher than 30 don't offer any further UV protection, and let the same 3% of UV rays through as SPF 30. Furthermore, SPF only applies to UVB rays. For that reason, it's just as important to look specifically for UVA protection, ie broad spectrum.
Be wary of using just one application of AloeGator if you're in the sun for a long time. I couldnt find an ingredient list for it, so you can't be sure how photostable the active ingredients are. You could still be getting a good dose of UVA without getting burnt. If anyone has a tube of it can they post the active ingredients please. The thick gel formula sounds good for long water sessions.
The Environmental Working Group (www.ewg.org) did a big review of 889 name-brand sunscreens (see
www.ewg.org/skindeep/). They found that 83% of the products offer inadequate protection from the sun, or contain ingredients with significant safety concerns. Only 17% of the products on the market are both safe and effective, blocking both UVA and UVB radiation, remaining stable in sunlight, and containing few if any ingredients with significant known or suspected health hazards.

Half of the banana boat sunscreens got a poor score in the EWG review so check which one yours is here

OCTINOXATE (OCTYL METHOXYCINNAMATE) - Estrogenic effects noted in laboratory animals at concentrations close to those experienced by sunscreen users.
PADIMATE O (OCTYL DIMETHYL PABA) - A derivative of the once-popular PABA sunscreen ingredient, research shows this chemical releases free radicals, damages DNA, has estrogenic activity, and still causes allergic reactions in some people.

The SPF15 rating is due to not yet meeting some Theraputical Goods Administration red tape to be able to claim more than that. Its been independantly lab tested much higher. Its ingredient list is pretty similar to one of the top rated sunscreens (
www.cosmeticdatabase.com/product.php?prod_id=92830) I dont find it too stingy when it gets in my eyes. It goes on well and smells so good I want to eat it. Its in an oil base, which is good for water resistance, and has lots of natural antioxidants to protect the skin.
