Doesn’t last long
The sunscreen itself is good it just doesn’t feel like you get what you pay for. Maybe 2 applications for my two kids and it was gone. I had another brand of the same size and got so many more uses out of it!

The best spray sunscreen
I use this in combo with coppertone defend and care with zinc sunscreen cream. It works awesome and prevents burns. I apply the cream first and use this for double duty on the spots that tend to burn fast. I used on my kids too and it keeps them from burning as well. It’s especially handy to spray on on your hand and pat into the hairline to keep the scalp from being burned and doesn’t leave the white residue cream does in the hair.

Awesome
It didn’t leave your hands all orange like some can. I get a pretty good color just putting on one so I only apply more to missed spots. No s smell either with this one! Last awhile!
