Sunscreen sprays are convenient and easy to use, especially for hard-to-reach areas such as the back. However, they may not provide adequate coverage or protection if not applied properly or sufficiently. Sunscreen sprays should be shaken well before use and sprayed at a distance of about 15 cm from the skin. They should also be rubbed into the skin after spraying to ensure even distribution and absorption. Sunscreen sprays should be reapplied every two hours or after swimming, sweating, or towel drying
