Apply recommended amounts of broad-spectrum sunscreen with a sunburn protection factor (SPF) greater than or equal to 30 to all exposed skin and reapply every two hours, or as needed.
Exposure to ultraviolet radiation is the leading cause of premature aging, and skin cancers including melanoma. Using sun protection even on cloudy days will help prevent some of these problems. The American Academy of Dermatology recommends you wear a wide-brimmed hat, sun glasses and sun protective clothing. If you must be in the sun, use a sunscreen with a sun protection factor (SPF) of 30+ even on cloudy days.
- Sunscreens are only one of our defenses against ultraviolet radiation. It should never be considered the only defense.
- The first defense against UVR is avoiding peak UVR hours or dressing sensibly for protection. Sunscreen should be used with sunprotective clothing, including a hat and sunglasses
- Broad spectrum sunscreen (blocking both UVA and UVB) with an SPF of 30+ should be used on all unprotected skin, including lips, faces, tops of feet, hands, necks and ears.
- Sunscreen should be applied twenty minutes before going outside and reapplied every two hours while exposed
- Many dermatologists recommend that sunscreen be applied before leaving the house every morning, reapplied twenty minutes before an outdoor activity, and every two hours while exposed.
- Sunscreen should be reapplied after swimming or perspiring heavily.
- Sunscreens should be applied generously and evenly. One fluid ounce, or the equivalent of a full shot glass, is the approximate amount of sunscreen it required for one person each time it is applied.
- Sunscreens have an expiration date. Once that date is reached, they may lose effectiveness. Sunscreens should be thrown away when expired.
- Self tanning lotions do not contain sunscreens
- Using sunscreens and other sun protection methods are important in the winter. Snow reflects up to 80% of the sun’s rays.
- Sunscreen are important for blocking reflected UVR. Sand, concrete, snow, water, and other surfaces reflect UVR which has the same bad effect to your skin.
- Being SunAWARE is your best defense against premature aging and skin cancers, including melanoma.
