I've used this at my parents' home (Mom's super into natural sunscreens), and this is by far my favorite (amongst all of the ones I've tried). It's non-greasy, doesn't have much of a smell, and stays on well (even when swimming, for example). Good stuff. Only downside versus those new spray-on sunscreens is that it's not as easy to apply widely.
This is the first enviromentally marketed sunscreen I have tried but its worked great. It drys fast and then you can't even tell you have it one except for the fact you don't burn. Excellent product and i highly recommend it.
