防晒霜的保质期，真的非常重要！！

As sunscreen ages, its sun-protection ingredients degrade, reducing its effectiveness.

防晒霜老化后，防晒成分的纯度会降低，导致防晒效果变差。

Keeping a fresh bottle on hand, and using it every time you’re out in the sun, will keep you from getting sunburned and also help prevent skin cancer, the most common cancer of all.

准备一瓶保质期新鲜的防晒霜，每次出门有日晒时拿来用，能够防止晒伤，还能预防最常见的癌症皮肤癌。

If your sunblock doesn’t have an expiration date on the bottle for some reason, though, keep Dr. Shari Lipner’s advice in mind.

如果你的防晒霜不知为什么没有保质期，那就谨记莎莉•李普诺医生的建议。

防晒霜的保质期，真的非常重要！！1

“Sunscreens are designed to last for three years,” says the assistant professor of dermatology at Cornell University’s Weill graduate school of medicine.

“防晒霜一般都有三年的保质期，” 康奈尔大学威尔医学院皮肤医学科副教授莎莉•李普诺医生指出。

“If your bottle does not have a date printed on it, write the date that you purchased it [on the bottle] and make sure to discard after three years.”

“如果防晒霜瓶子上没有印有保质期，那么就在这瓶防晒霜上写上购买日期，确保满三年后不再使用。”

She also notes that storing your sunscreen in a hot car can degrade key ingredients, causing it to become less effective. “If the consistency seems off — runny or grainy,” she advises, “discard and buy a new sunscreen.”
