Washing your face seems pretty simple, yet dermatologists and beauty companies think there's room for improvement. 洗脸看起来特别简单，但皮肤科医生和化妆品公司却认为，它还有改进提高的空间。 Easy does it is the message experts have for consumers, as a new generation of facial cleansers promises mild formulas that won't dry out the skin. New devices offer deep-clean claims but with a lighter touch. Some doctors even say that people with good skin should wash their face just once a day -- at night. 随着新一代洁面产品问世，许诺其温和配方不会使皮肤变干，专家们向消费者传递出这样的信息：洁面别着急，需要放轻松。新产品宣称能够提供深度清洁，而且对皮肤的触碰也更为柔和。有些医生甚至称，皮肤好的人每天只应洗一次脸──在晚上洗。 It's a tough sell for consumers familiar with strong formulas that can make skin feel tight and squeaky clean. Many people take that feeling as a sign of effectiveness, when actually it is a signal of overdrying or damage. 这个说法很难让那些熟悉强力配方的消费者接受，这类配方能使皮肤感到紧绷和异常洁净。很多人认为这种感觉是产品效果好的表现，但实际上它是皮肤过干或受损的信号。 |
