SUNSCREEN 101:
FEBRUARY 2021
We’ve got you fully covered
One of the leading causes of skin cancer is the lack of using sunscreen. Skin cancer is the most common form of cancer in the United States, and having five or more sunburns can increase your risk of developing melanoma.
By protecting your skin from the sun’s UV rays, you can lower your risk of skin cancer. Here’s how you can soak up the sun — in the safest way possible.

Sunscreen isn’t just for summer
Did you know that even on cloudy days, up to 80 percent of the UV rays can penetrate the skin? And that snow, sand and water can also cause sun damage by reflecting UV rays? No matter the weather forecast, it’s important to wear sunscreen whenever you plan on heading outside.
Think more is more
Make sure to apply sunscreen anywhere that clothing doesn’t cover. The recommended amount of sunscreen for adults is about one ounce — or enough to fill a shot glass — for the entire body.
Time it out
Sunscreen should be applied at least 15 minutes before going outside.
Cover the forget-me-spots
The easiest spots to miss are also the easiest ones to burn. Don’t forget to apply (and reapply!) sunscreen to the tops of the feet, neck, ears, and top of the head. Your lips can also burn, so apply a lip balm with an SPF of 30 or more.
Reapply often
Reapply sunscreen every two hours, or immediately after swimming or sweating.
Check the expiration
Follow the expiration date listed on the sunscreen. Sunscreen without an expiration date has a shelf life of no more than three years, but its shelf life is shorter if it’s been exposed to high temperatures.
