Good but heavy smell
Item Package Quantity: 1
I will keep using this bc it works and the sprayer is sooo nice but the smell is so overwhelming. It’s not a bad smell but it’s just so heavy. I’ll use this one but I don’t see myself repurchasing.

Good but confusing instructions
It is very glowy. After spraying this on my husband commented on why I was sweating so much 😹 I told him it’s my face mist spf. I have very dry and very sensitive skin and this has not broken me out (yet). I’ve used it for about a week now. I don’t know how much sun protection I’m really getting though. And reapplying it all through out the day, esp in the summer will lead to very very oily looking skin.
It’s also confusing because it says do not spray directly onto face. (?) I just hold my breath and close my eyes tightly before I put my mascara on and spray this. So far it’s been helpful with not making my make up look cakey. There is a smell but it’s not a bad smell, slightly fruity and the smell of spf. If you are sensitive to smells this might not be for you.

So refreshing, you’ll forget it’s sunscreen.
This stuff is fantastic. I love the super fine mist and how easily the pump works. It is soo refreshing and smells like fresh coconut. Ot doesn’t sting or burn my sensitive eyes, and it leaves my skin feeling revitalized and moisturized, not sticky or tacky. It feels amazing when it’s hot outside and you need a quick refresh and it won’t disturb my makeup. Coola is becoming one of my favorite sunscreen brands.
