怎么保存护肤品

护肤品的“五防”原则

1、防热：温度过高的地方不宜存放护肤品，因高温不仅容易使护肤品中的水分挥发，化妆膏体变干，而且容易使膏霜中的油和水分离而发生变质的现象。因此，炎热的夏季不要在手袋中装过多的护肤品。

2、防晒：阳光或灯光直射处不宜存放护肤品，因为当护肤品受到阳光或灯光直射，会造成水分蒸发，以致某些成分会失去效力，甚至产生化学变化，使其效果降低。而且在购买时，不要选取放置在橱柜内的样品，因其长期受橱柜内灯光的照射，容易变质。

3、防冻：护肤品在冷处存放易发生冻裂现象，而且解冻后还会出现油水分离，使其中的一部分变粗变硬，对皮肤有刺激作用。

4、防潮：有些护肤品中含大量蛋白质和蜂蜜，受潮后容易发生霉变。也有的用铁盖玻璃瓶包装，受潮后铁盖容易生锈，腐蚀化妆品，使其变质。

5、防污染：护肤品中虽然都添加有防腐剂以防产品受污染变质，但仍不能杜绝万一，若其中有了xx则会伤害皮肤。因此，护肤品使用后一定要及时旋紧瓶盖，以免xx侵入繁殖。另外，护肤品一旦取用，如面霜、乳液，就不能再放回瓶中以免污染。

护肤品保存问答：

Q1. 一般护肤品的使用期限？

护肤品的使用期限取决于其中的保质剂成分，也就是我们传统上叫做防腐剂的东西。现在护肤品大多分成两类：一类是xx不添加保质剂成分的，这类产品xx密封、容量小，有效使用时间短。另一种是含有少量xx保质剂的，这类产品对皮肤本身也没有伤害，且稳定性佳、易于保存，在未开罐的情况下保质期在2年的时间。

Q2. 开封前的护肤品有什么保存方法？

首先，不要过早丢弃护肤品的外包装纸盒，裸露的产品更容易收到光照的伤害；其次，不要因为好奇而开启护肤品中的内盖，或剥离用来保持产品密封性的锡膜，因为在购买之前，你xx可以通过柜台配备的试用装去了解到产品的所有信息（气味、色泽、质地等）；{zh1}，就是将护肤品放置在通风、温差变化较小，且无直射光线的地方。

Q3. 护肤品在开封后该如何处理能保持{zh0}的使用效果？

一是避免光照和高温：高温和光照都会加速护肤品成分的变化，从而引发变质问题的产生。因此，护肤品购买回家后，应尽量放在常温的环境内，切忌放在窗台边或者浴室内。二是避免xx的滋生：选择专业的挑棒，或借助卫生棉签。手指和护肤品的直接接触可能会引发xx的滋生；每天使用一些专业的护肤小工具，可有效避免二次污染的产生，当然护肤功效也就会变得事半功倍！

Q4. 护肤品过了期，舍不得扔该怎样废物利用？

过期的护肤品如同过了保质期的食品，对皮肤而言有害而无益。但是价格不菲的护肤品，往往又让我们不舍丢弃。为了避免浪费，我们可利用洗面奶之类的清洁产品去替代平时使用的洗手液；面霜类的产品可用来清洁和光亮皮制用品；此外，含酒精的爽肤水更能帮助我们去除掉一些平时难以拭去的污渍。

Q5. 每年换季后没有用完的护肤品，到底该如何保存？

现下，有一种专门置放化妆品的小冰箱，其温度可以控制在15℃左右，而家用冰箱无法控温在这个恰当的幅度。像爽肤水之类的产品，我们可将其装回原包装盒中，再放进冰箱内冷藏。含油脂类的产品不推荐放入冰箱中，但可在存放之前，使用含酒精的化妆水清洁瓶口，然后旋紧瓶盖避光保存。

小窍门必读

1、虽然知道大包装的产品较易变质，但限于产品包装的规格有限，除了尽量选用小包装的产品，争取尽快使用完毕以外，在产品买回时立即将其进行分装也是方法之一。

2、注意看盒身上印有类似像罐子一样的标签，即表示产品开封后的保存期限，如6M（6个月）及24M（24个月）中的数字表示其可保存的月份。
