Colorscience has an amazing powdered sunscreen in a container with a brush that is mineral based. It is so good for kids' faces, instead of rubbing goopy sunscreen on your kids face you can quickly powder it on. It's not cheap, but one container lasts a long time. It's not amazing in the water we've found. You used to be able to buy powder refills for the container, but I am not seeing that you can anymore.
