　　In the four of a new weekly series, in association with LloydsPharmacy, a
trained pharmacist answers your common medicine queries...
        　　在四大每周新系列中，一名训练有素的药剂师携手劳埃德药店回答您的常见医药问题…
        　　Some suncreams have expiry dates, while others carry a symbol showing how
many months it can be used for once opened, explains Colin Dougall from
LloydsPharmacy in Glasgow.
        　　一些防晒霜标明了截止日期，而另一些则带有显示一旦打开后可以用多久的标记，来自格拉斯哥的劳埃德药房的科林.杜加尔解释说。
        　　If the product has neither, NHS Choices suggests a shelf life of two to
three years if it’s stored correctly, ie, in a cool, dry place.
        　　如果在该产品上两者都没有标注，英国健康搜索引擎(NHS Choices)建议如果储存正确的话，即保存在阴凉，干燥的地方，保质期为两到三年。
        　　After the expiry date - or if it’s been stored in a hot car for the summer
– your suncream may degrade and not protect you as well from the sun so it’s
probably best to discard it and buy a new one next season.
        　　到期之后—或者如果它一夏天被放在闷热的车里，你的防晒霜可能会变质，便不能保护你远离阳光照射，所以最好丢掉它，等到下个季节再买一个新的。
        　　But if you’re applying suncream regularly – it should be reapplied several
times a day and after swimming, even if it is waterproof – you’re unlikely to
have much left after your holidays anyway.
        　　但是，如果您定期使用防晒霜，每天重复使用很多次，游泳后也会用，即使它是防水的，相信你的假期过后，它也不可能剩下多少了。
