Lightweight, fast application
My go-to face sunscreen now. My favorite for rushed mornings when I don’t have much time. Tried a bunch of options including dove men care, Tula, juice beauty, cerave, laroche posay, and lumin. This and Jaxon Lane Rain or Shine are my favorites. Neither makes your skin feel dry or coated in stuff. This one smells like cinnamon to me. Slight eye burn as the alcohol evaporates, but doesn’t get into my eyes or burn during the day. Pretty good discount on Amazon sometimes!

Lightweight but questionable coverage
I traditionally used the Coola face lotion but had switched to the spray for my body so I figured I’d try the face spray. It doesn’t smell as bad as a lot of the reviews say it does. It also doesn’t really smell “tropical” for that matter, but it isn’t unpleasant. It sprays evenly and doesn’t feel heavy or greasy. My only complaint is I still got a little burnt. Full disclosure: I’m super fair and have to reapply every 30-60 minutes, even without getting wet. So maybe it’s not meant for people with as pale a complexion as me. Or I have to constantly reapply, or put the lotion underneath. But otherwise I really liked it and really like Coola products.

Must have for a hot summer!
My mom saw my aunt using it and was impressed, so she bought it for herself and my sister-in-law. They both love how gentle it feels on the skin and that it’s organic and effective.

Too smelly
I love the idea of a clear spray sunscreen but my daughter says it stings her eyes and the smell gives me an instant headache. I really wanna like this but it’s a no go for me

Great for sensitive skin
This was great to take on vacation. I went to Cancun and used this on my face. Never got burned. I have super sensitive skin and this didn’t cause any reactions. I’m also sensitive to smells and I don’t notice anything with this product. Will purchase again.
