Understanding SPF

SPF stands for sun protection factor. You’ve likely seen it on sunscreen labels. It’s a measure of how effective the product is at blocking the sun’s ultraviolet (UV) radiation. Dermatologists typically recommend choosing sunscreen with an SPF of at least 30, and reapplying it every two hours.
