Obviously you have to keep reapplying
Did you ever notice how many people get bad burns on their first day of vacation even though they used sunscreen ?
SPF is built up by a reaction between the sunscreen lotion chemicals and your skin, which takes a certain amount of time to happen. Those that don't have a good base tan and just rub on the sunscreen on their "virgin" skin the first day at the resort are likely to be very sore that evening........
