Spray-on sunscreen is a convenient form of sun protection that comes in an aerosol can. It is designed to be applied directly to the skin, allowing for quick and even coverage. Users simply spray the product onto their skin and then rub it in to ensure full protection against harmful ultraviolet (UV) rays from the sun. This type of sunscreen is popular for its ease of use, especially for those who are active or on the go. However, it is important to apply enough product and to reapply it regularly, especially after swimming or sweating, to maintain effective sun protection.
