Can a sunscreen be water resistant?
By using certain ingredients the sunscreen products can be made water resistant. The definition of water resistant is that the product will retain its sun protective effect even after swimming or perspiring. Caution should be taken when using water resistant sunscreens because a false feeling of safety may cause the user to stay too long in the sun. Even with water resistant sunscreens it is important to re-apply the sunscreen regularly especially after swimming or exercise.
