Prevention of sun damage is a critical part of good skin care. Regular use of sunscreen will prevent or delay a variety of skin conditions including some skin cancers, premature wrinkling of the skin, and uneven pigmentation. A sunscreen with at least an SPF 30 and with UVA and UVB coverage is recommended. When swimming, choose a water-resistant formulation. Reapply sunscreen every 4 hours while outdoors or every 2 hours if swimming or sweating.
