How much sunscreen should I wear every day?

The average amount of sunscreen that an adult needs to cover their entire body is a shot glass full. Your sunscreen bottle should not last you all summer. One sunscreen bottle should cover a whole family.

Sunscreen can help prevent sun damage and skin cancer, but how much is enough? In this video featuring Dr. Oz guest Anne Chapas, M.D., you'll find out how some common household products can help you get the perfect amount of protection.

Apply enough sunscreen to fully cover all exposed areas of your body, including your face, eyelids, lips, back, and the backs of your arms and legs. In total, you should use about an ounce of sunscreen, or about the amount that would fit into a shot glass. Most people only apply a small fraction of the sunscreen they need to fully protect them. After you apply the sunscreen, rub it in completely. Don't forget to reapply your sunscreen after about two hours, or more often if you've been swimming or sweating heavily. Talk to a dermatologist for more information.

Amount of sunscreen to wear daily depends on where you live, what clothes you're wearing, and how long you'll be outside. Your Fitzpatrick Skin Type - how fair or dark your skin is - should also be a clue as to how much protection you need. If you're in Miami in the middle of summer and you're outdoors a lot, you'll need a stronger sunblock, applied over more of your exposed body, than someone wearing a suit in New York City on a cloudy fall day. If it's bright and sunny and you're outside for more than a few minutes, wear a sunblock on exposed areas of skin (including hands, ears, neck, chest, arms, and legs). Unless you're in direct sun all day long, you probably don't need to worry about reapplying sunblock on your body, but do put it on before you go out. Don't overthink it or rationalize that you might not need it. Remember, the sun's rays are killer laser beams. If they're going to be hitting you, protect your skin with the sunblock.
It's mandatory to apply a sunscreen every single day - no matter what - on your face, neck, ears, and upper chest (if it's visible). If most of your body is covered with clothing (which usually has an SPF of less than 10) and you spend much of your time inside, it's not necessary to apply sunscreen head to toe every day - although if you like a particular body lotion with sunscreen, by all means wear it every day. And use a hand cream with added sunscreen while you're at it, to help prevent the wrinkling and sun spots that are telltale signs of your age. (Most women's hands, chests, and shoulders look years older than their faces, just because they neglect to protect and moisturize them).

Spending time outside can be fun, but painful sunburn isn't. At all times of the year -- even on cloudy days -- sun protection from the sun's harmful UV rays is needed. Step one is sunscreen or sunblock with a high SPF. (And don't ...

forget to reapply!). The sun's UV rays are strongest during the middle of the day so your risk for sunburn is higher, despite using sunscreen and taking other protective measures. Get more information about protecting your skin from sun damage with expert advice from Sharecare.
