Neutrogena Ultra Sheet Dry Touch Sunblock
I like it because it is sheer and non greasy and doesn't have a sunscreen smell to it. It's not the cheapest of sunscreens so we only use it for faces and ears. We buy the SPF 45 or 55... I have seen it come in higher SPFs such as 100 but I'm not sure if research really supports that an SPF higher than 45/55 is that much better so I stick with this and reapply it about every 2 hours while in the sun :)
Do you have a sunscreen you like?
