Protect Your Skin From The Sun

Protective Measures

From the Skin Cancer Foundation:

Protect yourself from UV radiation, both indoors and out. Always seek the shade outdoors, especially between 10 AM and 4 PM. And since UVA penetrates glass, consider adding flat, tinted UV-protective film to your car’s side and rear windows as well as to house and business windows. This film blocks up to 99.9 percent of UV radiation and lets in up to 80 percent of visible light.

Outdoors, dress to limit UV exposure: Special sun-protective clothes with UPF (ultraviolet protection factor) indicate how much UV radiation can penetrate the fabric; the higher the UPF, the better. A shirt with an UPF of 30, for example, means that just 1/30th of the sun’s UV radiation can reach the skin. Laundry additives can also be washed right into regular fabrics to provide higher UPFs. However, you can enhance your sun safety simply by learning to evaluate everyday fabrics’ sun protection qualities and choosing those with the best protection. For instance, bright- or dark-colored, lustrous clothes reflect more UV radiation than do pastels and bleached cottons; and tightly woven, loose-fitting clothes provide more of a barrier between your skin and the sun. Finally, broad-brimmed hats and UV-blocking sunglasses help shield the sensitive skin on your head, neck, and around the eyes — areas that usually sustain a lot of sun damage.

Sun Protection Factor (SPF) and UV Radiation

Since the advent of modern sunscreens, a sunscreen’s efficacy has been measured by its sun protection factor, or SPF. SPF is not an amount of protection per se. Rather, it indicates how long it will take for UVB rays to redden skin when using a sunscreen, compared to how long skin would take to redden without the product. For instance, someone using a sunscreen with an SPF of 15 will take 15 times longer to redden than without the sunscreen. An SPF 15 sunscreen screens 93 percent of the sun’s UVB rays; SPF 30 protects against 97 percent; and SPF 50, 98 percent. The Skin Cancer Foundation maintains that SPFs of 15 or higher are necessary for adequate protection.

Sunscreen Ingredients

Since both UVA and UVB are harmful, you need protection from both kinds of rays. To make sure you’re getting effective UVA as well as UVB coverage, look for a sunscreen with an SPF of 15 or higher, plus some combination of the following UVA-screening ingredients: stabilized a avobenzone or helioplexTM, ecamsule (a.k.a. Mexoryl™), oxyben-zone, titanium dioxide, and zinc oxide. You may see the phrases multi spectrum, broad spectrum or UVA/UVB protection on sunscreen labels, and these all indicate that some UVA protection is provided. However, because there is no consensus on how much protection these terms indicate, such phrases may not be entirely meaningful.

There are currently 17 active ingredients approved by the FDA for use in sunscreens. These filters fall into two broad categories: organic/chemical and inorganic/physical. Most UV filters are organic: They form a thin, protective film on the surface of the skin and absorb the UV radiation before it penetrates the skin. The inorganic sunscreens are insoluble particles that reflect UV away from the skin. Most sunscreens contain a mixture of organic and inorganic active ingredients.

Right Now

To date, no criteria exist in the U.S. for measuring and labeling the amount of UVA defense a sunscreen provides. However, the FDA plans to introduce UVA standards within the next few years.

The FDA would demand that manufacturers assess the sunscreen’s ability to screen out UVA with a series of tests, then the FDA would assign the sunscreen a 1 to 4 star rating, with 1 star indicating the lowest and 4 the highest amount of UVA protection. Manufacturers whose products did not meet the minimum requirements would have to label their products “No UVA protection.” New labels with UVA and UVB protection ratings might look like this:

Meanwhile, for your skin’s sake, use a sunscreen with an SPF of 15 or higher every day to protect against UVB, along with some combination of UVA-shielding ingredients. And be aware that no matter what sunscreen you use, some UV radiation still gets through to your skin. So always follow a complete prevention program that includes seeking the shade and wearing protective clothing.

If you follow our comprehensive Prevention Guidelines, you can enjoy yourself outdoors while staying protected from both UVA and UVB year-round, whatever the weather, wherever your locale.

Prevention Guidelines

• Seek the shade, especially between 10 AM and 4 PM.
• Do not burn.
• Avoid tanning and UV tanning booths.
• Cover up with clothing, including a broad-brimmed hat and UV-blocking sunglasses.
• Use a sunscreen with an SPF of 15 or higher every day.
• Apply 1 ounce (2 tablespoons) of sunscreen to your entire body 30 minutes before going outside. Reapply every two hours, or immediately after swimming or excessive sweating.
• Keep newborns out of the sun. Sunscreens should be used on babies over the age of six months.
• Examine your skin head-to-toe every month.
• See your physician every year for a professional skin exam.

Sun Safety for Skiers

The combination of higher altitude and ultraviolet (UV) rays reflected by the snow puts skiers and snowboarders at an increased risk of sun damage and ultimately, skin cancer. More than 90 percent of all skin cancers are caused by sun exposure. It’s easy to associate winter with frostbite and windburn, but most people are unaware that UV rays can be even more damaging on the slopes than on the beach,” said Perry Robins, MD, President, The Skin Cancer Foundation. “With the coldest months ahead of us, it’s more important now than ever to make people aware of the proper precautions to take while on the slopes.”

Higher altitude means increased levels of harmful UV exposure compared to sea level areas. UV exposure increases 8-10 percent with every 1,000 feet above sea level. At an altitude of 9-10,000 feet, UV may be 45-50 percent more intense than at sea level. In addition, snow reflects about 80 percent of the UV light from the sun, meaning that you are often hit by the same rays twice. This only contributes to the problem, further increasing the risk for skin cancer.

Both snow and strong wind can wear away sunscreen and reduce its effectiveness, so you have to take extra precautions. To protect your skin from the bitter cold, heavy winds and winter sun, follow these important sun protection tips:

• Use a broad-spectrum sunscreen with an SPF of 15 or higher whenever you spend time outdoors. Apply 30 minutes before hitting the slopes.Be aware that the sun’s reflection off the snow is strong even on cloudy days.

• Apply sunscreen liberally and evenly to all exposed skin - most skiers and snowboarders do not use enough sunscreen and therefore do not get the maximum protection.

• Use a more moisturizing sunscreen. Winter conditions can be particularly harsh on the skin.

• Be sure to cover often-missed spots: lips, ears, around eyes, neck, underside of chin, scalp and hands.

• Always wear a lip balm with an SPF 15 or higher. Lips are even more sensitive than most parts of the skin.

• Reapply at least every two hours, and more often after sweating or exposure to wind and snow.

• Carry a travel-sized sunscreen and lip balm with you on the slopes. Reapply on the chairlift, especially after a long, snow-blown run.

Cover up.

• Wear items like ski masks, which will cover most of the skin, leaving very little exposed to the wind and sun.

• UV-blocking sunglasses or goggles that offer 100% UV protection and have wraparound or large frames protect your eyelids and the sensitive skin around your eyes, common sites for skin cancer and sun-induced aging. The sun’s rays and glare can impair your vision, so it’s important to wear sunglasses or goggles to clearly see the terrain. Plus, it will increase your enjoyment and performance while skiing.

Be mindful of time spent in the sun, regardless of the season.

• Keep track of the time you spend in full sunlight. If possible, ski early in the morning and later on in the day, before 10AM and after 4PM. This helps avoid long lines and decreases the amount of time spent outdoors in the most intense hours of sunlight.

• If you are on the slopes for most of the day, take a few breaks indoors to reapply sunscreen.

• Drink plenty of water to avoid dehydration from the sun.

Enjoy the winter season, but be sure to take care of your skin to avoid the damage the cold season can cause. The first organization in the U.S committed to educating the public and medical professionals about sun safety,
