Prevention and Alternative Treatment for Sunburn
Prevention
To prevent sunburn, everyone over the age of six months should use a water-resistant sunscreen with a sun protective factor (SPF) of at least 15. Apply at least an ounce of sunscreen 15-30 minutes before going outside.
It should be reapplied every two hours (more often after swimming). Babies should be kept completely out of the sun for the first six months of life, because their skin is thinner than the skin of older children. Sunscreens have not been approved for infants.
