How to Apply Sunscreen

You probably know that you need to apply sunscreen while you’re laying out on the beach. However, dermatologists recommend that you use a sunscreen any time you’re going to be outside for more than 20 minutes, even in the wintertime.[1] You should wear sunscreen even when it’s shady or overcast. The sun’s UV (ultraviolet) rays can begin to cause skin damage in just 15 minutes![2] This damage can even lead to skin cancer.

EditSteps

EditChoosing a Sunscreen

  1. Look at the SPF number. “SPF” refers to a sunscreen’s “sun protective factor,” or how long it blocks UVB rays. The SPF number reflects the amount of time it takes to sunburn wearing the sunscreen vs. not wearing the sunscreen.[3]

    • For example, an SPF of 30 means that you can spend 30 times as long in the sun before burning compared to not wearing any sunscreen at all.[4] So, if you would usually begin to burn after 5 minutes in the sun, an SPF of 30 would theoretically allow you to spend time outside for 150 minutes (30 x 5) before you burn. However, your unique skin, your activities, and the sun’s intensity all cause variation in how effective sunscreen is, so you may need to use more than other people.
    • The SPF number can be tricky, because its protection doesn’t increase proportionally. Thus, SPF 60 is not twice as good as SPF 30. SPF 15 blocks about 94% of UVB rays, SPF 30 blocks about 97%, and SPF 45 blocks about 98%. No sunscreen blocks 100% of UVB rays.[5]
    • The American Academy of Dermatology recommends an SPF of 30 or higher.[6] The difference between extremely high SPFs is often negligible and not worth the extra money.
  2. Choose a “broad-spectrum” sunscreen. SPF refers only to the ability to block UVB rays, which cause sunburn. However, the sun also emits UVA rays. UVA rays cause skin damage, such as signs of aging, wrinkles and dark or light spots.[7] Both increase your risk of skin cancer.[8] A broad-spectrum sunscreen provides protection from both UVA and UVB rays.[9]

    • Some sunscreens may not say “broad-spectrum” on the packaging. However, they should always state whether they protect against UVB and UVA rays.
    • Most broad-spectrum sunscreens contain “inorganic” components such as titanium dioxide or zinc oxide, as well as “organic” sunscreen components such as avobenzone, Cinoxate, oxybenzone, or octyl methoxycinnamate.[10]
  3. Look for a water-resistant sunscreen. Because your body expels water through sweat, you should look for a water-resistant sunscreen. This is especially important if you are going to be very active, such as running or hiking, or if you’ll be in the water.[11]
    Apply Sunscreen Step 3.jpg
    • No sunscreen is “waterproof” or “sweat proof.” In the US, sunscreens cannot market themselves as “waterproof.”[12]
    • Even with water-resistant sunscreen, reapply every 40-80 minutes or as directed on the label.
  4. Decide what you like. Some people prefer spray sunscreens, while others prefer thick creams or gels. Whatever you decide, make sure you apply a thick, even coating. The application is as important as the SPF and other factors: if you don’t apply it properly, the sunscreen won’t do its job.[13]
    Apply Sunscreen Step 4.jpg
    • Sprays may be best for hairy areas, while creams are usually best for dry skin.[14] Alcohol or gel sunscreens are good for oily skin.[15]
    • You can also purchase wax sunscreen sticks, which are good for applying near the eyes.
    • Water resistant sunscreens are usually sticky, so they are not good choices for applying under makeup.[16] Use a sunscreen specific for your face. These often have higher SPF (15 or higher), and are less likely to clog pores or increase acne breakouts.
  5. Go home and try a small portion around your wrist. If you see any allergic reaction or skin problem, buy a different sunscreen. Repeat the process until you find the right sunscreen, or talk to your doctor about recommended brands if you have sensitive skin or allergies.

    • Itching, redness, burning, or blisters are all signs of an allergic reaction. Titanium dioxide and zinc oxide are less likely to cause allergic skin reactions.[17]

EditApplying a Sunscreen

  1. Check the expiration date. The FDA requires sunscreen to retain its protective power for at least three years from the date of manufacture. However, you should always note expiration dates. If the date has passed, ditch the old bottle and buy some new sunscreen.[18]
    Apply Sunscreen Step 6.jpg
    • If your product doesn’t have an expiration date when you purchase it, use a permanent marker or a label to write the purchase date on the bottle. This way you’ll know how long you’ve had the product.
    • Obvious changes in the product, such as color changes, separation, or different consistency, are signs that the sunscreen has expired.
  2. Apply before going out in the sun. The chemicals in sunscreen take time to bind to your skin and become fully protective. Apply your sunscreen before you go out.[19]
    Apply Sunscreen Step 7.jpg
    • Sunscreen on the skin should be applied 30 minutes before you go out into the sun. Lip sunscreen should be applied 45-60 minutes before going into the sun.[20]
  3. Use enough. One of the biggest mistakes in using sunscreen is to not use enough. Adults usually need about one ounce -- a palmful, or about a shot glass full -- of sunscreen to cover exposed skin.[21][22]
    Apply Sunscreen Step 8.jpg
    • To apply cream or gel sunscreen, squeeze a dollop into your palm. Spread it all over the skin that will be exposed to the sun. Rub the sunscreen into your skin until you can't see the white anymore.
    • To apply spray sunscreen, hold the bottle upright and move the bottle back and forth across your skin. Apply an even, generous coating. Make sure the wind doesn’t blow the sunscreen away before it contacts your skin. Don’t inhale spray sunscreen. Be careful when applying spray sunscreens around the face, especially around children.
  4. Apply sunscreen to all skin. Remember areas like your ears, neck, the tops of your feet and hands, and even the part in your hair. Any skin that will be exposed to sunlight should be covered with sunscreen.[23]
    Apply Sunscreen Step 9.jpg
    • It can be hard to fully cover hard-to-reach areas such as your back. Ask someone to help you apply sunscreen to these areas.[24]
    • Thin clothing often doesn’t offer much sun protection. For example, a white t-shirt has an SPF of just 7. Wear clothing designed to block UV rays, or wear sunblock under your clothes.[25]
  5. Don’t forget your face. Your face needs even more sunscreen than the rest of your body, as many skin cancers occur on the face, especially on or around the nose. Some cosmetics or lotions may contain sunscreen. However, if you’re going to be outside for more than 20 minutes (total, not at a time) you’ll want to apply a facial sunscreen too.
    Apply Sunscreen Step 10.jpg
    • Many facial sunscreens come in cream or lotion form. If you use a spray sunscreen, spray it into your hands first, then apply it to your face. It's best to avoid spray sunscreens on the face if possible.
    • The Skin Cancer Foundation has a searchable list of recommended facial sunscreens.[26]
    • Use a lip balm or lip sunscreen with an SPF of at least 15 on your lips.
    • If you are bald or have thin hair, remember to apply sunscreen to your head, too. You can also wear a hat to help protect against sun damage.[27]
  6. Reapply after 15-30 minutes. Studies have shown that re-applying your sunscreen after about 15-30 minutes after going into the sun is more protective than waiting 2 hours.[28]
    Apply Sunscreen Step 11.jpg
    • Once you’ve done this initial reapplication, re-apply sunscreen every 2 hours or as directed on the label.

EditStaying Safe in the Sun

  1. Stay in the shade. Even when you’re wearing sunscreen, you’ll still be exposed to the sun’s powerful rays. Staying in the shade or using a sun umbrella will help protect you from sun damage.[29]
    Apply Sunscreen Step 12.jpg
    • Avoid “peak hours.” The sun is highest between 10AM and 2 PM. If you can, avoid sun exposure during this time. Seek shade if you’re out and about during this time.[30]
  2. Wear protective clothing. Not all clothing is created equal. However, long-sleeved shirts and long pants can help protect your skin from sun damage. Wear a hat to offer your face extra shade and protect your scalp.[31]
    Apply Sunscreen Step 13.jpg
    • Look for tightly-woven fabric and dark colors, which offer the most protection. For people who are very active outdoors, there is special clothing with built-in sun-protection, available at specialty stores or online.
    • Remember those sunglasses! The sun’s UV rays can cause cataracts, so purchase a pair that block UVB and UVA rays.
  3. Keep young children out of the sun. Sun exposure, especially during the “peak” hours of 10 AM to 2 PM, is especially harmful to young children. Look for sunscreens specifically made for children and babies. Consult with your pediatrician to determine what is safe for your child.[32]
    Apply Sunscreen Step 14.jpg
    • Infants under the age of 6 months should not wear sunscreen or be exposed to direct sunlight. Young babies’ skin is not mature yet, so they may absorb more of the chemicals in sunscreen. If you must take young infants outside, keep them in the shade.[33]
    • If your baby is older than 6 months, use a broad-spectrum sunscreen with an SPF of at least 30. Be careful when applying sunscreen near the eyes.[34]
    • Dress young children in sun-protective clothing, such as hats, long-sleeved sun shirts or lightweight long pants.[35]
    • Get your child sunglasses with UV protection.[36]

EditTips

  • Buy a special sunscreen for your face. If you have oily skin or tend to get clogged pores, look for “oil-free” or “noncomedogenic” sunscreens. Special formulas are available for sensitive skin.
  • Even if you apply sunscreen, do not overexpose yourself in the sun.
  • Reapply sunscreen after getting wet, every 2 hours, or as directed on the label. Sunscreen isn’t a “one and done” product.

EditWarnings

  • There is no such thing as a “safe” tan. UV light from tanning beds and natural sunlight causes skin cancer. A golden tan may look great, but it isn’t worth your life.
