I use the California Baby Sunblock stick on my daughter and also Earths Best Chemical Free SPF Lotion. They both go on thick and leave a white film. The stick is a bit challenging to use because it is very thick, but if you get it a bit warm it works better. I definitely wouldn't recommend the stick for anywhere other than faces, hands, and feet. It could take all day to do the whole body with it. Overall I think both of these products work well, and my daughter hasn't had any problems with either one. The other nice think about the stick is that you aren't likely to get it in baby's eyes, since it doesn't run at all.
I hope that helps.
