Safe and effective sunscreens

As summer approaches (in Houston, it is already here), it's time to purchase sunscreen. I never paid much attention to what brand I purchased until my kids were born.
When they were really young, I used to just keep them out of the sun. Then, I started buying "baby" sunscreen. A couple of years ago, I came across an article (I think in the Washington Post) on the best sunscreens. It quoted research from the environmental working group.
Probably no surprise to many people, a lot of ingredients found in popular sunscreens contain harmful ingredients. A lot of common ingredients just aren't very effective. And those baby sunscreens? Most of them aren't as harmless as they appear, just packaged for advertising.
What I like about the EWG's site is that it has a good list of effective sunscreens as well as a function that you can use to search for sunscreens, including store brands. Basically, when looking for a sunscreen look for zinc, titanium dioxide, or avobenzone as the active ingredient. Avoid sunscreens With oxybenzone or vitamin A. Also avoid the two in one products that have sunscreen and bug repellent. You need to reapply sunscreen every so often, and it is not safe to be exposing skin to all that repellent. For people that want to be extra careful, avoid spray-ons as well.
I really liked the Blue Lizard brand, but it has become quite difficult to find. I noticed Aveeno has one that is a top pick this year on the list, The baby natural mineral block face stick. One other point to keep in mind is to make sure you double check the active ingredients. Many brands, like Aveeno and Blue Lizard, have sunscreens with different ingrediants.
I highly recommend the EWG sunscreen website. It has a lot of useful information. They also have a smartphone app, but I have not used it.
