Optimal Protection from UV

Sunscreens work by limiting the amount of the ultraviolet B (UVB) energy in sunlight that your skin absorbs. The SPF level of a sunscreen tells you how much of the sun's UVB energy your skin remains exposed to after application.

An SPF 30 sunscreen protects skin from about 97 percent of UVB and allows only about three percent of UVB to be absorbed by your skin. Products with SPF 30 ratings are often recommended for use during long periods of sun exposure. For daily use, a product with SPF 15 may suffice.

SPF 45 sunscreens, which protect the skin from about 97.8 percent of UVB, may be beneficial for certain individuals who require more protection. If your skin is especially sun sensitive due to its color, medications or skin care products that you use, you may need a sunscreen with an SPF level of 50 or above. Your doctor can recommend the ideal SPF level to give you adequate sun protection every day and when you'll be outdoors for extended periods.

Sunscreen Products for Every Need

Experts typically recommend the use of broad-spectrum sunscreen, which protects skin from ultraviolet A (UVA) energy in addition to UVB. Some broad-spectrum sunscreens with SPF levels of 20 to 45 are made especially for the face and are ideal to use as everyday sun protection.

For swimming and exercising outdoors, you can purchase a sport sunscreen with a water and sweat-resistant formulation which works while you are swimming or sweating (although still must be reapplied regularly). Special SPF 20 to 45 products are available for sensitive skin and for babies and children.
