如何挑選防曬霜

FIRST THingS FIRST: Before your reach for a sunscreen, you should know that whatever you might use, it won’t make you invincible to the sun’s rays. That is, sun protection shouldn’t start with sunscreen, experts say.

首先：在挑選防曬霜之前，你應該知道：無論使用哪一款產品，都不能百分百防護光線中的紫外線。所以，專家表示，防曬並不應從防曬霜開始。

There are many ways to moderate your exposure to potentially harmful ultraviolet rays, and you should take advantage of various approaches to do just that. “You should try to do everything else first,” explains Dr. Robert Dellavalle, a professor of dermatology and public health at the University of Colorado. “And what is everything else? Well, it’s seeking shade, avoiding the midday sun, doing your activities early in the morning or late in the afternoon.” Aim to wear sun-protective clothing, too, like a light, long-sleeved shirt, as well as sunglasses.

很多方法都可以起到防護有害紫外線的作用，你應該利用這些方法。“你應該先做些其它事情，”科羅拉多大學皮膚病學和公共衛生學教授羅伯特·德拉瓦勒（Robert Dellavalle）博士解釋道。“其它方法包括什麼呢？尋找蔭涼處、避免正午陽光的照射、早上早出門、晚上晚回家。”最好穿上防曬衣，或輕薄的長袖襯衫，同時戴上太陽鏡。

Also of note, there are mineral-based sunscreens – like those made with zinc oxide or titanium oxide – and chemical sunscreens. “Chemicals can affect the environment, they can affect your skin – they can cause rashes,” Dellavalle says. “So only when you’re planning on being outdoors and cannot wear clothing or use one of these other options to protect your skin, then you should be using sunscreen.” So if you’re going swimming, you’ll want to be choosy about the sunscreen you use – and know how they differ.

值得注意的是，有些防曬霜含礦物質——比如含有氧化鋅或氧化鈦的防曬霜——化學防曬霜。“化學物會污染環境，也會對你的皮膚造成影響——引起皮疹，”德拉瓦勒說道。“所以，只有在你準備外出且無法穿防曬衣或使用其它防曬方法保護皮膚時，才應該塗防曬霜。”如果你準備去游泳，應仔細挑選防曬霜，瞭解它們的差別。

Particularly for those who have sensitive skin, a mineral-based or so-called physical sunscreen is a good choice. But with chemical sunscreens the formulation is more elegant and tends to be easier to rub in, says Dr. Arisa Ortiz, an assistant clinical professor of dermatology at the University of California San Diego and director of laser and cosmetic dermatology at UC San Diego Health. “So if you’re sensitive or have many allergies, then I would opt for the physical sunscreen,” she says. “Otherwise if you don’t like that white residue, the chemical sunscreen would be better.”

對於敏感肌而言，礦物質防曬霜或所謂的物理防曬霜都是一個不錯的選擇。但化學防曬霜的成分更講究、更易塗抹，加利福尼亞大學聖地亞哥分校的皮膚病學助理臨牀教授兼加利福尼亞大學聖地亞哥分校健康中心的激光和化妝品皮膚科主任愛麗莎·奧爾蒂斯（Arisa Ortiz）博士說道。“所以如果你的肌膚敏感易過敏，建議您選擇物理防曬霜，”她說道。“如果不喜歡塗太白，化學防曬霜會更適合您。”

Whichever you choose, to protect your body’s largest organ and help prevent skin cancer, it’s key to pick a sunscreen that has you safely and effectively covered. “The most important thing to look for is a sunscreen that says broad spectrum protection,” Ortiz says. “What that means is it’s going to protect against all UVA and UVB rays.”

無論挑選哪一款防曬霜，只要您用的安全且有效就能起到保護身體的最大器官、預防皮膚癌的作用。“最重要的是選擇一種廣效性全面防護的防曬霜，”奧爾蒂斯說道。“也就是說，這款防曬霜能防護所有的紫外線。”
