The vast majority of skin cancers, as well as most of the visible signs of aging, are caused by the sun’s harmful ultraviolet (UV) light. Since UV damage is cumulative over our lifetime, it is something we have to be concerned about on a daily basis. Fortunately, incorporating sun protection into your everyday routine is easy. Whether you’re at work, on vacation, out exercising or with friends, Linda K. Franks, MD; Bruce Katz, MD; Jordana Gilman, MD, and Doris Day, MD, have the answers you need to stay sun-safe.

Sun protection should be a priority at work, even if your office is indoors. That’s because the sun’s UV radiation reaches us as both long-wave UA rays and short-wave UVB rays, and while window glass largely blocks UVB, UVA can pass right through. In a recent study, subjects who regularly worked indoors with one side of the face directly exposed to a window developed noticeably more wrinkles, brown spots, and sagging skin on that side of the face.
It’s not just people who sit at a desk (or work outdoors) who are at risk: if your job requires much time in a vehicle, UVA can reach you through the side windows there, too.
When you prepare for work in the morning, you may apply moisturizer or makeup along with sunscreen. If your AM routine involves more than one product, follow the correct application order:
- Medication. If you use a prescription topical medication, this should always be the first product applied to a clean, washed face.
- Moisturizer. A moisturizer worn on top of medication will not interfere with the topical treatment and could actually enhance its penetration. A moisturizing sunscreen will save you a step, but if you prefer using separate products, apply the moisturizer before the sunscreen.
- Sunscreen. Your sunscreen should be broad-spectrum, protecting against both UVA and UVB rays. Its sun protection factor (SPF), which measures protection from the sun’s UVB rays, should be at least 15. For extended outdoor activity, use a water-resistant broad spectrum (UVA/UVB) sunscreen with an SPF of 30 or higher.
- Makeup. Apply foundation first, then powder and blush. An SPF 15+ lip balm is also a good idea. Loose or pressed powder mineral makeup is a great addition, since it contains sunscreens like titanium dioxide and zinc oxide — insoluble minerals that block or reflect UVR away from the skin. The powder should catch any spots you have missed, and will make sunscreen touchups easier.

Sunny vacations can easily damage your skin. It’s not just the amount but also the type of sun exposure you receive that’s a problem. Whether you’re headed to the shore or the slopes, take precautions.
On the Beach
Intermittent, intense sun exposure — the kind you might experience on a beach vacation, resulting in sunburn — has been linked to both basal cell carcinoma, the most common form of skin cancer, and melanoma, the deadliest skin cancer. In a recent study, researchers found that young, white English women who vacationed in hotter countries had 74 percent more moles than women who had not. The more moles you have, the higher your melanoma risk. Minimize risk by applying a full ounce (two tablespoons) of a water-resistant, broad spectrum (UVA/UVB) SPF 30+ sunscreen to your entire body 30 minutes before heading to the beach. Reapply every two hours or immediately after swimming or sweating heavily.
UV exposure does not have to be direct to damage the skin. Indirect UV rays also pose an often-overlooked risk, since they can bounce off reflective surfaces and hit the skin a second time. On the beach, sand reflects 15 percent of UV light; water reflects up to 10 percent, and sea foam, 25 percent. You can minimize exposure by hitting the beach before 10 AM or after 4 PM—the sun (and heat) will be less intense, and you’ll miss the crowds.
Many beachgoers wear nothing but a swimsuit, but studies show that clothing is the single most important factor in sun protection. It’s advisable to cover as much skin as possible before and after you go in the water. Loose-fitting, long-sleeved shirts or blouses and long pants will shade your arms and legs, while UV-protective glasses and a hat with a broad brim (at least 3 inches all the way around) will go a long way to keep your head and face sun-safe. Tunics can be a happy medium for women, with long, loose sleeves and hems that reach the knees, covering more of the torso than the usual shirt. Wraparounds such as sarongs are also a light and comfortable form of protection. And three-quarter-length pants (a.k.a. clam diggers) will give men more leg coverage than standard shorts.
Beachgoers can also benefit from specially made clothing. Look for clothes with a UPF (Ultraviolet Protection Factor) label. UPF indicates what fraction of the sun’s ultraviolet rays can penetrate the fabric. For instance, a swimsuit with a UPF of 50 lets just 1/50th of the sun’s UV radiation penetrate the fabric. The Skin Cancer Foundation recommends clothing with UPFs of 30 or more.
Surfers and swimmers should have no trouble finding sport-specific protective gear. Synthetic and semi-synthetic fibers like nylon and Lycra offer great UV protection with beach basics such as wetsuits, rash guards, and swim shirts.
In the Snow
While “sunny vacation” usually suggests a beach holiday, the sun in cold weather getaways can be every bit as intense as summer exposure. Again, reflection can be a serious problem, since snow reflects up to 80 percent of solar UV rays and can nearly double UV exposure. Skiers and snowboarders beware: UV exposure increases 8-10 percent with every 1,000 feet above sea level. Plus, both snow and strong wind can wear away sunscreen and reduce its effectiveness, so reapply a moisturizing sport sunscreen regularly.
When you’re on the slopes, cover as much of your face as you comfortably can, with close-fitting wraparound sunglasses or goggles that block 99-100 percent of UV radiation. This will help cut down glare, and also protect your eyes, the second most common site for melanomas. A ski cap or a hat with ear flaps will go a long way towards protecting the ears and scalp, two common sites for skin cancer.

If outdoor exercise is a priority for you, make sure sun protection is also on the agenda!
A broad-spectrum (UVA/UVB) sunscreen is a must, and for extended periods outdoors, a water-resistant or very water-resistant sunscreen with an SPF of 30+ is recommended. Active people have numerous sunscreen options, since current sport sunscreens are water-resistant, lightweight, easily absorbed, and don’t run into the eyes or sting. There are also an array of delivery options, from lotions and gels to wipes, which makes reapplication a breeze. For instance, you may want to apply a spray sunscreen before you leave the house and carry a stick with you for quick reapplication after two hours.
Excessive UV exposure and high-intensity exercise can harm the immune system, making athletes particularly vulnerable to illnesses, including skin cancers. Schedule outdoor exercise before 10 AM or after 4 PM, when the sun is less intense.
Some over-the-counter pain relievers (like ibuprofen and naproxen) can increase sun sensitivity, causing the skin to burn in less time and in response to less sun exposure. If you regularly take pain relievers to ease your aches and pains after a vigorous workout, be extra careful in the sun. Other common medications that can increase sun sensitivity include antibiotics, diuretics, topical retinoids, oral contraceptives, and antidepressants.
The heat can tempt athletes to shed clothes, sacrificing sun safety for comfort, but today’s sportswear is made of lightweight, high-tech fabrics specially treated to be “breathable” and “sweat-wicking.” Tightly woven athletic tops and shorts keep out more UV radiation than those made of fabrics with loose or open weaves (like mesh).
Remember to keep your head covered. While a broad-brimmed hat (such as an outback or bucket hat) offers the most protection, it may not be feasible in certain sports; however, even a cap will protect the vulnerable scalp. Foreign legion-style hats are another option, offering extra protection for the back of the neck.

When you’re spending time outdoors with friends and family, follow these tips to maximize fun while minimizing sun damage:
99-100 percent UV-blocking sunglasses can make a chic fashion statement while also protecting you from eyelid cancers, which account for five to 10 percent of all skin cancers. While few are lethal, they can cause significant tissue damage, leading to disfigurement and even blindness. The bigger the lenses, the better.
Fedoras and other wide-brimmed hats are another great way to protect from the sun and make a fabulous fashion statement. Hats made of dark or bright-colored fabrics provide more protection than light-colored hats, and those made of densely woven, opaque material (like canvas) are preferable to those made of straw.
Put Your Best Face Forward
If you wear makeup when you go out with friends, take the opportunity to add an SPF15+ mineral powder. Not only will mineral powder give your skin a glamorous matte finish, you’ll be augmenting the sunscreen you’ve already applied.
Seek the Shade
Sometimes, you can increase sun safety just by moving a few feet. Shade is an important element of sun protection: look for trees with large spreads of dense foliage, and ones near other trees or buildings, to further block out the sky. Also use parasols or sun umbrellas whether you’re walking, lying in the sand, or sitting at a picnic table.
Remember, it is vital to protect your skin on a daily basis. Read our Prevention Guidelines for a concise list of The Skin Cancer Foundation’s everyday sun safety strategies.
