Getting sunburned from the Ultraviolet rays (UV,紫外线), no matter what your age is, is a risk factor for skin cancer.
Use sunscreen
Only about 19 percent of older men and 32 percent of older women report regularly using sunscreen, according to a 2019 study. But everyone should apply it to exposed skin whenever they’ll be outside, even on cloudy days. While the best sunscreen is one that you’ll use continually, our testing has found that some products perform better than others, even if they’re both marked with the same SPF. Members can find our full ratings at CR. org/sunscreen.
Attend to tricky spots
Don’t forget your ears, the tops of your feet, the backs of your hands, and the back of your neck.
Put sunscreen on 15 minutes before you go outside. Be sure to apply enough—try to use 1 teaspoon for each exposed body part. Reapply every 2 hours and after swimming or sweating.
