Choose a sunscreen with an SPF (sun protection factor) of at least 15.
Apply sunscreen 30 minutes before going outside, and reapply every two hours if you need to stay in the sun for long.
Reapply sunscreen after swimming, sweating or towel drying.
Apply sunscreen generously. Use about 1 ounce of sunscreen for good coverage.
Make sure you choose a tested sunscreen that protects against both UVA and UVB rays
