Sun Sense: What You Must Know

By avoiding sun damage, you’re not only preserving your skin’s health but also its appearance. Practicing good sun sense will result in fewer wrinkles, discolorations, and will help your skin resist developing the most insidious type of sun damage: skin cancer.
•There is no such thing as a safe tan, whether it is from the sun or a tanning booth.
•UVB radiation is the sun's burning ray and has an immediate, harmful impact on skin. Damage from UVB rays takes place within the very first minute (yes, 60 seconds) of walking outside.
•UVA rays are the sun's silent killers. You don't feel them but they are the primary cause of skin cancer, wrinkles, and a weakened immune system. (UVA rays penetrate through clear glass windows that do not have a UV coating.)
•Even on a cloudy or hazy day, the sun's rays are present and impacting the skin.
•Sitting in the shade or wearing a hat only protects against a portion of the sun's rays. Surrounding surfaces such as water, cement, and grass reflect rays from the ground to your skin giving you double the exposure.
•Altitude is a sun enhancer: for every 1,000-foot increase in altitude, the sun's potency increases by 4%. Don’t forget the sunscreen when you’re skiing!
•A product's SPF (sunscreen protection factor) number tells you how long you can stay in the sun before getting burned.  The formula is 10 (minutes) x 15(SPF) = 150 (minutes), or 2 1/2 hours. If you're swimming or perspiring, you must wear a water-resistant sunscreen which provides 40 to 80 minutes of protection.
•It is best to apply sunscreen LIBERALLY at least 15 to 20 minutes before sun exposure. This gives the sunscreen time to absorb and to spread over and into the uppermost layers of skin. Avoid expensive sunscreens as one may not be as apt to apply them liberally.
•Did you know that sunburn continues to develop for 12 to 24 hours after the initial burn? Treat a sunburn like any burn. Do not cover it with thick salves (thick moisturizers are the worst). These will trap the heat and cause more damage. Get the skin in contact with cool (not cold or icy) water or pure aloe vera immediately (do not put ice directly on the skin—that's too much cold and can cause a different kind of burn). Then keep applying the cool water or pure aloe vera on and off for several hours.
