I tried the Cucumber version via Birchbox and loved it! It does leave a white-ish cast on your face (nothing like using pure zinc would - it just kind of makes your face appear paler, which can be remedied with a tinted moisturizer, powder, etc.).
The formula is awesome - I like it because it's not a chemical-based sunscreen (talk about break outs and bad reactions. I rue the day I ever tried Supergoop on my face lol!). Since the Coola leaves a matte, non-sticky finish, I imagine makeup would apply well over it. It's not greasy at all and smells nice and natural.
