The best way to apply sunscreen is to make sure to apply it liberally and evenly all over exposed skin at least 20 minutes before going outdoors. Reapply sunscreen every 2 hours and after swimming or sweating. If you will be outside for a long period of time, you should consider bringing along a travel-sized bottle of sunscreen to reapply throughout the day. Remember to use a sunscreen with a SPF of 30 or higher.
