1. Soap is Bad for Your Skin. 香皂对皮肤有害。
Traditionally, soap was a mix of animal fats and fruit or vegetable oils. This combination has a higb PH and is drying to skin, particularly to aging skin. These days, however, soaps are formulated with synthetic elements that are milder than traditional soap, and therefore suitable to cleanse skin. Most soaps have emollients(moisturisers) added, so they are beneficial for the skin. If you prefer the feeling cleansing with soap provides, don't let those purveyors of fine skincare bully you--there's nothing wrong with using soap.
传统上,香皂是动物脂肪和水果油或植物油的混合体。这种化合物的PH值很大,会令皮肤,尤其是老化皮肤,变得干燥。如今,香皂的配方中加入了较传统香皂更为温和的人工合成成分,因而适合清洁皮肤。大多数香皂都添加了润肤剂(润肤霜),所以对肌肤有益。如果你更喜欢用香皂洁肤的那种感觉,就不要让那些高档护肤品经销商们把你给喊住了——使用香皂一点儿问题都没有。
