Everyone. Sunscreen use can help prevent skin cancer by protecting you from the sun’s harmful ultraviolet rays. Anyone can get skin cancer, regardless of age, gender or race. In fact, it is estimated that one in five Americans will develop skin cancer in their lifetime.1,2
The American Academy of Dermatology recommends everyone use sunscreen that offers the following:
- Broad-spectrum protection (protects against UVA and UVB rays)
- Sun Protection Factor (SPF) 30 or higher
- Water resistance
A sunscreen that offers the above helps to protect your skin from sunburn, early skin aging3 and skin cancer. However, sunscreen alone cannot fully protect you. In addition to wearing sunscreen, dermatologists recommend taking the following steps to protect your skin and find skin cancer early:
- Seek shade when appropriate, remembering that the sun’s rays are strongest between 10 a.m. and 2 p.m. If your shadow is shorter than you are, seek shade.4
- Wear protective clothing, such as a long-sleeved shirt, pants, a wide-brimmed hat and sunglasses, when possible.
- Use extra caution near water, snow and sand as they reflect the damaging rays of the sun, which can increase your chance of sunburn.
- Get vitamin D safely through a healthy diet that may include vitamin supplements. Don’t seek the sun.5
- Avoid tanning beds. Ultraviolet light from the sun and tanning beds can cause skin cancer and wrinkling. If you want to look tan, you may wish to use a self-tanning product, but continue to use sunscreen with it.6
- Check your birthday suit on your birthday. If you notice anything changing, itching or bleeding on your skin, see a board-certified dermatologist. Skin cancer is very treatable when caught early.
Every day if you will be outside. The sun emits harmful UV rays year-round. Even on cloudy days, up to 80 percent of the sun’s harmful UV rays can penetrate your skin.7
Snow, sand, and water increase the need for sunscreen because they reflect the sun’s rays.7
- Use enough sunscreen to generously coat all skin that will be not be covered by clothing. Ask yourself, “Will my face, ears, arms or hands be covered by clothing?” If not, apply sunscreen. Most people only apply 25-50 percent of the recommended amount of sunscreen.8
- Follow the guideline of “1 ounce, enough to fill a shot glass,” which dermatologists consider the amount neededto cover the exposed areas of the body. Adjust the amount of sunscreen applied depending on your body size.
- Apply sunscreen to dry skin 15 minutes BEFORE going outdoors.
- Skin cancer also can form on the lips. To protect your lips, apply a lip balm or lipstick that contains sunscreen with an SPF of 30 or higher.
- Reapply sunscreen approximately every two hours, or after swimming or sweating, according to the directions on the bottle.
Sunlight consists of two types of harmful rays that reach the earth — UVA rays and UVB rays. Overexposure to either can lead to skin cancer. In addition to causing skin cancer, here’s what each of these rays do:
- UVA rays (or aging rays) can prematurely age your skin, causing wrinkles and age spots, and can pass through window glass.
- UVB rays (or burning rays) are the primary cause of sunburn and are blocked by window glass.
The United States Department of Health & Human Services and the World Health Organization’s International Agency of Research on Cancer have declared UV radiation from the sun and artificial sources, such as tanning beds and sun lamps, as a known carcinogen (cancer-causing substance). 9
There is no safe way to tan. Every time you tan, you damage your skin. As this damage builds, you speed up the aging of your skin and increase your risk for all types of skin cancer.
Sunscreen products are regulated as over-the-counter drugs by the U.S. Food and Drug Administration. The FDA has several safety and effectiveness regulations in place that govern the manufacture and marketing of all sunscreen products, including safety data on its ingredients.
Thanks to a 2011 FDA ruling, sunscreen labels now provide you with more information about what type of UV protection a sunscreen offers and what a sunscreen can do.
On the label, you’ll see whether the sunscreen:
- Is Broad Spectrum, which means the sunscreen protects against UVB and UVA rays and helps prevent skin cancer and sunburn.
- Has an SPF of 30 or higher. While SPF 15 is the FDA's minimum recommendation for protection against skin cancer and sunburn, the American Academy of Dermatology recommends choosing a sunscreen with an SPF of at least 30.
- Has a Skin Cancer/Skin Aging Alert in the Drug Facts section of the label, which means the sunscreen will only prevent sunburn and will NOT reduce the risk of skin cancer and early skin aging
- Is Water Resistant (effective for up to 40 minutes in water) or Very Water Resistant (effective for up to 80 minutes in water). This means the sunscreen provides protection while swimming or sweating up to the time listed on the label.
- Sunscreen manufacturers now are banned from claiming that a sunscreen is "waterproof" or "sweat proof," as the FDA has determined that those terms are misleading.
- Even when using a water-resistant sunscreen, you should reapply after getting out of the water or after sweating.
Using sunscreen, seeking shade and wearing protective clothing are all important behaviors to reduce your risk of skin cancer. Scientific evidence supports the benefits of using sunscreen to minimize short-term and long-term damage to the skin from the sun’s rays. Preventing skin cancer and sunburn outweigh any unproven claims of toxicity or human health hazard from ingredients in sunscreens.
The best type of sunscreen is the one you will use again and again. Just make sure it offers broad-spectrum (UVA and UVB) protection, has an SPF of 30 or higher and is water resistant.
The kind of sunscreen you use is a matter of personal choice, and may vary depending on the area of the body to be protected. Available sunscreen options include lotions, creams, gels, ointments, wax sticks and sprays.
- Creams are best for dry skin and the face.
- Gels are good for hairy areas, such as the scalp or male chest.
- Sticks are good to use around the eyes.
- Sprays are sometimes preferred by parents since they are easy to apply to children. Make sure to use enough of these products to thoroughly cover all exposed skin. Do not inhale these products or apply near heat, open flame or while smoking. It is important to note that current FDA regulations on testing and standardization do not pertain to spray sunscreens. The agency continues to evaluate these products to ensure safety and effectiveness.
- There also are sunscreens made for specific purposes, such as for sensitive skin and babies.
Some sunscreen products are also available as combination products in moisturizers and cosmetics. While these products are convenient, they also need to reapplied in order to achieve the best sun protection.
Sunscreen may also appear in combination with an insect repellant. The Academy recommends that these products are purchased and used separately — sunscreen needs to be applied generously and often, whereas insect repellant should be used sparingly and much less frequently.
Regardless of which sunscreen you choose, be sure to apply it generously to achieve the UV protection indicated on the product label.
Dermatologists recommend using a sunscreen with an SPF of at least 30, which blocks 97 percent of the sun’s rays. Higher-number SPFs block slightly more of the sun’s rays, but no sunscreen can block 100 percent of the sun’s rays. Currently, there is not any scientific evidence that indicates using a sunscreen with an SPF higher than 50 can protect you better than a sunscreen with an SPF of 50.
It is also important to remember that high-number SPFs last the same amount of time as low-number SPFs. A high-number SPF does not allow you to spend additional time outdoors without reapplication. All sunscreens should be applied approximately every two hours or according to time on the label, even on cloudy days, and after swimming or sweating.
The FDA is currently investigating the risks of accidental inhalation of spray sunscreens. The challenge in using spray sunscreens is that it is difficult to know if you have used enough to cover all sun-exposed areas of the body, which may result in inadequate coverage.
Never spray sunscreen around or near the face or mouth. Spraying adequate amounts of the sunscreen into your hands and then applying the sunscreen can help you avoid the fumes while also ensuring adequate coverage. When applying spray sunscreens on children, be aware of the direction of the wind to avoid inhalation.
Ideally, parents should avoid exposing babies younger than 6 months to the sun’s rays.
The best way to protect infants from the sun is to keep them in the shade as much as possible, in addition to dressing them in long sleeves, pants, a wide-brimmed hat and sunglasses. Make sure they do not get overheated and that they drink plenty of fluids. If your baby is fussy, is crying excessively or has redness on any exposed skin, take him or her indoors.
Sunscreen use should be avoided if possible in babies younger than 6 months.
Parents of infants and toddlers 6 months and older may apply a broad-spectrum, water-resistant sunscreen with an SPF of 30 or higher to their children’s exposed skin that is not covered by protective clothing, according to the instructions on product label. The sunscreen should be reapplied approximately every two hours, or as often as the label says. Sunscreens that use the ingredients zinc oxide or titanium dioxide, or special sunscreens made for infants or toddlers may cause less irritation to their sensitive skin.10
Dermatologists recommend using sunscreen every day when you are outside, not just during the summer. If you are using sunscreen every day and in the correct amount, a bottle should not last long. If you find a bottle of sunscreen that you have not used for some time, here are some guidelines you can follow:
- The FDA requires that all sunscreens retain their original strength for at least three years.
- Some sunscreens include an expiration date. If the expiration date has passed, throw out the sunscreen.
- If you buy a sunscreen that does not have an expiration date, write the date you bought the sunscreen on the bottle. That way, you’ll know when to throw it out.
- You also can look for visible signs that the sunscreen may no longer be good. Any obvious changes in the color or consistency of the product mean it’s time to purchase a new bottle.
Using sunscreen may decrease your skin’s production of vitamin D.
For more information on vitamin D and UV exposure, check out the Academy’s vitamin D fact sheet.
It’s important to begin treating a sunburn as soon as possible. In addition to stopping further UV exposure, dermatologists recommend treating a sunburn with:
- Cool baths to reduce the heat.
- Moisturizer to help ease the discomfort caused by dryness. As soon as you get out of the bathtub, gently pat yourself dry, but leave a little water on your skin. Then apply a moisturizer to trap the water in your skin.
- Hydrocortisone cream that you can buy without a prescription to help ease discomfort.
- Aspirin or ibuprofen. This can help reduce the swelling, redness and discomfort.
- Drinking extra water. A sunburn draws fluid to the skin surface and away from the rest of the body. Drinking extra water prevents dehydration.
Do not treat sunburns with “-caine” products (such as benzocaine).
If your skin blisters, you have a second-degree sunburn. Dermatologists recommend that you:
- Allow the blisters to heal untouched. Blisters form to help your skin heal and protect you from infection.
- If the blisters cover a large area, such as the entire back, or you have chills, a headache or a fever, seek immediate medical care.
With any sunburn, you should avoid the sun while your skin heals. Be sure to cover the sunburn every time you head outdoors.
