Getting sunburned from the Ultraviolet rays (UV，紫外线), no matter what your age is, is a risk factor for skin cancer. 1．. And while using sunscreen (防晒霜) whenever you’re spending time in the sun is key among sun safety strategies, other measures matter, too. Here are tips from the sun safety experts on how to keep your skin burn-free and healthy.

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.

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.

3．

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.

Double your protection

4．. So if you’re out for a while, cover up with lightweight long sleeves and pants. You can skip sunscreen on those covered areas. And a wide-brimmed (宽边的) hat is always a good idea to protect your forehead and face.

Get the right sunglasses

You might find it challenging to apply sunscreen very close to your eyes, but these spots are likely to be burned, too. 5．. Wearing sunglasses can help. Choose a pair labeled with “UV absorption up to 400nm”or a statement that the glasses block 100 percent of UVA and UVB rays.
