Don’t bother

Spray sunscreen seems like such a great idea, until you burn!
The idea of it is great, don’t get your hands messy, fast and easy. But in reality if you do not spread this product in with your hands and apply a lot it’s not doing anything for you. I have olive tone skin and tan very easily and don’t easily burn but on a recent vacation I applied some spray sunscreen and I burnt on day 1. Everywhere except for the strips I had from the exact places I sprayed. So perhaps if I sprayed much more it would have helped. But also any little breeze in the air is blowing the sunscreen away so it will take half a can to properly protect yourself.
On top of that the pressure from the airplane affected one of my bottles and it wouldn’t spray, which has happened in the past with hairspray, the pressure in the air is not great for aerosol cans. So unless your vacationing in Canada when the weather is less than 30 degrees I would skip this product and go for regular cream based sunscreen.
