Reduce sun exposure and protect your skin from the sun. Wear protective clothing such as hats, long-sleeved shirts, long skirts, or pants. Ultraviolet light is most intense midday, so try to avoid sun exposure during these hours.

Use high-quality sunscreens, preferably with SPF (sun protection factor) ratings of at least 15. Pick a sunscreen that blocks both UBA and UVB light. Apply sunscreen at least 30 minutes before going out into the sun, and reapply frequently. Sunscreen should be used year-round, including in the winter.
