When you're active and enjoying the sun, like at the beach or a ballgame, it's important to reapply after that.
当你一边运动一边享受阳光时,比如在沙滩上嬉戏或参与球类运动,最重要的是在活动结束后必须重新涂抹一次防晒霜。
If you put on an SPF of 50 at 10 a.m., by noon, "you're probably still getting some protection, but your SPF 50 is no longer accurate," Zampella said. "Maybe you're getting SPF 10 at that point."
如果你在上午10点涂上了SPF 50的防晒霜,那么到中午为止,“你可能还能获得一些保护,但此时SPF 50的防晒能力就得不到保证了。 ” Zampella 说 ,“也许你在那个时候只能获得SPF 10的防晒效果。”
For full-fledged protection, use at least SPF 30
为了获得全面保护,请至少使用SPF 30的防晒霜
That's what the American Academy of Dermatologists suggests.
这点是美国皮肤科医学会给出的建议。
SPF 30 also happens to be the dose that skin expert David Leffell, author of "Total Skin: The Definitive Guide to Whole Skin Care For Life," and chief of dermatological surgery at Yale School of Medicine, keeps on hand for himself at home.
《全面护肤:全面护肤生活的权威指南》作者,耶鲁大学医学院皮肤病外科主任David Leffell平时给自己使用的防晒霜指数也恰好是SPF 30。
