早上起床洗脸也要有度,当心越洗越油


造成皮膚敏感的因很多,包括年齡、內分泌等內在因素,以及壓力、不良情緒、飲酒、辛辣刺激飲食等外界因素。其中,過度清洗是導致皮膚敏感的一個很常見也很重要的原因。
我們皮膚的最外層是角質層,其外有一層由汗液和皮脂乳化而成的皮脂膜,為人體提供保護。過度清洗、使用不當化妝品(如堿性大的肥皂洗臉),不僅除去了皮膚表麵的灰塵、老化角質、微生物等,也破壞了正常的皮脂膜,達不到護膚的目的,反而會破壞了皮膚。尤其是油性皮膚(比如常長痘)的人,總想把臉上所有的油脂都清洗掉,希望以此來改善毛囊堵塞、痤瘡的症狀。殊不知,這樣反而會讓皮膚更油。因為皮膚局部環境也存在反饋調節,皮脂膜能抑製皮脂腺分泌。過度清潔使皮脂喪失,皮脂膜抑製皮脂腺分泌的壓力減輕,反而使皮脂腺分泌速度增快,會分泌更多的油脂,造成油光滿麵。
過度清潔還會造成皮膚屏障功能受損,皮膚失水速度增加、缺水、幹燥粗糙;保護作用被削弱,有害微生物、外界化學、物理、生物因素容易入侵或刺激,尤其容易受到紫外線傷害,在使用潔膚、化妝品時感到刺痛。
皮膚敏感的人,建議使用與體溫相近的36℃~37℃的水洗臉,避免對皮膚造成冷熱刺激;用溫和的不含皂基的潔膚產品;盡量不用去角質產品,選用不含香料、不含防腐劑、刺激性小的醫學護膚品及物理防曬劑;並注意生活規律,放鬆心情。

Sino-German digital summit held in Hamburg



HAMBURG, German — A Sino-German digital summit was held Tuesday, with some 200 officials and businessmen from China and Germany gathering here to discuss the latest trend of digitalization in both countries and deeper cooperation in the related fields.

The summit was a followup event to the G20 summit held in Hamburg on July 7-8, which had included digitalization as one of its major topics.

During the digital summit, China's key digital enterprises like Alibaba Group had talks with Germany's major digital companies such as Otto Group.

China is the world's largest and most rapidly growing market of digitalization, which has great influence on European companies and their business, said Ragnar Kruse, CEO and co-founder of Smaato, a leading global mobile advertising platform and also a partner of the digital summit.

Hamburg is a city that has a key position in Germany's digital economy and it is also regarded as China's gateway into Europe. Over 550 Chinese enterprises have investment in the city.
