Does spray sunscreen work?

Yes - spray & rub: Yes, if you spray and rub it in. The main trouble with the spray is that there is a risk of breathing in the aerosolized particles. These chemicals are not meant or safe to use internally. So when spraying, be sure not to spray directly onto face.

Yes but more often: Certsinky but it may need to be applied more often depending on your activity level, sweating pattern, and bathing.
