Q1:为什么人的皮肤上会出现皱纹?


原因:


皮肤生来就有纹路的,纵横交错,医学上叫皮纹,皮纹交错划开的部分叫皮丘,人的皮肤是有无数个皮丘和皮纹构成的。只是因皮肤细腻,光泽富有弹性,视角上往往看不出来。


一般来讲,皱纹主要是皮肤老化的结果,别是皮肤最外的致密角质层中水分含量及天然保湿因子含量减少,使皮肤的水和能力下降,结果皮肤组织细胞皱缩老化,皮肤细小皱纹产生。


扩展资料


分类


一、体位性皱纹


如颈部的皱纹,为了颈部能自由活动,此处的皮肤会较为充裕、自然形成一些皱纹,甚至刚出生就有。早期的体位性皱纹不表示老化,只有逐渐加深、加重的皱纹才是皮肤老化的象征。


二、动力性皱纹


动力性皱纹是表情肌长期收缩的结果,主要表现在额肌的抬眉纹、皱眉肌的眉间纹、眼轮匝肌的鱼尾纹、口轮匝肌的口角纹和唇部竖纹、颧大肌和上唇方肌的颊部斜纹等。


三、重力性皱纹


40岁以后,由于皮肤、肌肉的松弛,在重力作用下,会逐渐下垂、局部折叠,形成重力性皱纹。常见的如眼袋、老年(老年食品)性上睑皮肤松垂、双下颌等。


(1)眼睑部位:多见于上睑外1/3处。由于重力关系,在上睑可随着眼皮和皮肤轮匝肌的逐渐松弛而发生皮肤下垂,下睑有时亦会逐渐下垂,同时还会由于眶隔脂肪从隔膜疝出而形成“眼泡”。


(2)面部:此类皱纹多发生于面下部,由于睑下脂肪垫的脂肪减少,睑颊部皮肤变得松弛,从而出现皱纹。


(3)颌部:此类皱纹多发生于颌下部,由于皮下脂肪减少,下颌皮肤松弛形成“垂下颌”。


(4)颈部:颈部的体位性皱纹发生在中年以后,由于皮下组织逐渐萎缩减少,皮肤松弛,加上重力作用而加多加深,特别在颈前部,常会在两侧颈阔肌的颈中缘形成两条下垂的皮肤皱纹。

    假期According to the US Department of Agriculture, global production of sugar is up 9 million tons to a record of 180 million metrics tons a year and consumption hovers at the 172 million metric ton level, also a record high level前两晴暖The American Heart Association (AHA) recommends that people should drink no more than three cans of soda (about 450 calories) a week, but men drink 175 and women 94 calories a day天中The DPRK walked out of the talks in April 2009 in protest against UN sanctions

    东部Abe, who also heads the LDP, is set to provisionally dissolve the lower chamber of Japan's bicameral system of parliament on Sept 28, as this is when the extraordinary Diet session will be convened, according to LDP sources close to the matter假期However, the prime minister has the authority to dissolve the lower chamber and call a general election at will前两晴暖This scenario would see official campaigning for the national poll kick off on Oct 10, with voters thereafter casting their ballots on Oct 22天中A lower house election must be held by December 2018 as this is when the four-year terms of current lower house lawmakers expire

    If Abe goes ahead with his plan to call a snap election, then three by-elections that have been slated to take place on Oct 22 would be replaced by the general electionThe opposition camp, however, has criticized Abe's move to call a snap election, with some accusing him of merely trying to escape from the influence-peddling scandals he is currently implicated in and engineering his stay in power

    假期前两天中东部晴暖

    "Nikai on Tuesday, during a meeting of ruling LDP executives reportedly conveyed Abe's intentions and relayed the party's determination to get all of its candidates fielded in the racePrior to Abe's departure Monday for a five-day trip to New York to attend the UN General Assembly, Abe told Nikai during a meeting that he "will decide on the timing of the snap election after returning from the UN General Assembly on FridayAbe last dissolved the lower house of parliament in November 2014 and thereafter led the ruling coalition to a sweeping victory in the following election in DecemberIn addition, the fact that new opposition parties in the process of being formed will not have time to organize themselves and mount a serious challenge to Abe and the LDP in such a short space of time, has made many political watchers question Abe's regard for democracy and the will of the people

    TOKYO - Japanese Prime Minister Shinzo Abe is gearing up to dissolve the lower house of parliament and call a snap general election, Liberal Democratic Party (LDP) Secretary General Toshihiro Nikai confirmed on TuesdayThe support rate for Abe's cabinet has improved moderately recently, and the opposition camp has accused the prime minister of taking advantage of this and have slammed the possible general election as being unnecessary and serving Abe's personal, not political objectivesThe application for UNESCO heritage status submitted by more than 10 groups from China, the Republic of Korea and other countries and regions will "allow the world to fully understand the brutality of the war of agrression, remember history, cherish peace and defend human dignity," Chinese Foreign Ministry spokesperson Lu Kang said at a regular news briefingBEIJING -- Japan should act correctly towards an application for records of comfort women to be listed as UNESCO heritage, instead of threatening not to pay its UNESCO membership fees, a Chinese spokesperson said Monday

    If the submitted documents are approved for the UNESCO Memory of the World Register next month, domestic pressure for Japan to cancel payment of its UNESCO membership fees will grow, according to Japanese media"The members of international organizations are obliged to pay their membership fees on time and in full

    假期前两天中东部晴暖

    China demands Japan reflect on its history of aggression, and take a correct attitude towards and do not smear or meddle with the application," Lu saidThe move serves the purposes of the UNESCO, he said

    Forceful recruitment of comfort women, or sex slaves, was a grave crime committed by the Japanese militarism during WWIIThere is solid evidence and no room for denying that, Lu saidHe said that Japan should handle the issue properly and in a responsible way to gain trust from its Asian neighbors and the international communityPeople from the DPRK and the ROK belong to the same ethnic group, and China has always supported the two countries in strengthening exchanges, improving ties and promoting reconciliation, he saidLu's comment came after ROK President Moon Jae-in suggested that his country could go ahead with humanitarian aid to the DPRK "regardless of political situations," despite Japanese Prime Minister Shinzo Abe's request for consideration of the timing of the proposed aidBEIJING -- China hopes that concerned parities can understand and respect the emotions of the people and support normal exchanges between the Democratic People's Republic of Korea (DPRK) and the Republic of Korea (ROK), Foreign Ministry spokesperson Lu Kang said Monday

    "All the UN Security Council resolutions that imposed sanctions on the DPRK, including the newly adopted Resolution 2375, have stated clearly that they are not intended to have a negative effect on the livelihoods and humanitarian needs of the people there," Lu said at a daily press briefing"I think this is not only good for China, but will also be a positive influence to the whole international system," he said

    For example, Singapore can become a launchpad for Chinese companies to march into international markets, and they can make the best of Singapore's trade and service facilities as a financial center and transport hubSingapore's cooperation with China concerning the Belt and Road Initiative, Lee said, is focused on infrastructure inter-connectivity, financial projects and third-country programs such as personnel training, which Singapore believes can combine advantages of both sides

    The two sides are expected to exchange views on bilateral ties and issues of common concern, the Chinese Foreign Ministry announced FridayIn the interview, Lee said the Initiative-related cooperation in sectors such as infrastructure investments, trade and tourism can help further "integrate China into regional and international economic systems while greatly boosting the prosperity and development in other countries

    The Belt and Road Initiative, put forward by Chinese President Xi Jinping in 2013, is aimed at building the Silk Road Economic Belt and the 21st Century Maritime Silk Road through concerted efforts of all related countries to benefit all participants by promoting unimpeded trade, financial integration, infrastructure inter-connectivity and closer people-to-people exchangesThe Singaporean leader will pay an official visit to China on Sept 19-21 at the invitation of Chinese Premier Li Keqiang"The Initiative will help foster closer cooperation among China and its neighboring countries as well as its trade partners in Europe, Asia and even Africa," he added"We deem the Belt and Road Initiative as positive," Lee said Saturday in an interview with Xinhuanet, Xinhua's official website, noting that China's continuous economic growth has made China an increasingly larger and more important part in the international system

    SINGAPORE -- Singaporean Prime Minister Lee Hsien Loong has said that the Belt and Road Initiative of China is positive to the world since it can help further integrate China into regional and international economic systems while boosting growth in other countries" In his opinion, the Initiative can help China make more and better contributions to global economic and trade cooperation as well as the international relations

    One option is to hold a snap election on Oct 22, when three by-elections are scheduled, the sources saidTOKYO - Japanese Prime Minister Shinzo Abe is considering calling a snap election for as early as next month to take advantage of his improved approval ratings and disarray in the main opposition party, government and ruling party sources said on Sunday

    Other possibilities are later in October or after an expected visit by US President Donald Trump in early November"Until now, it appeared the election would be next autumn, but

    Abe's ratings have recovered to 50 percent in some pollswe must always be ready for battle," domestic media quoted Komeito party chief Natsuo Yamaguchi as telling reporters on Saturday during a visit to RussiaAbe told executives of his Liberal Democratic Party and its junior coalition partner, the Komeito party, that he might dissolve parliament's lower house for a snap poll after the legislature convenes for an extra session from Sept 28, the sources saidAbe will probably make a decision after returning from a Sept 18-22 trip to the United States, the sources said

    Top LDP and Komeito officials will meet on Monday to discuss preparations, they added"We need to be clear that the latest UN resolution not only sanctions the DPRK's nuclear activities but also calls for the reopening of dialogue and resolving the issue through consultations," Cui said

    "Without implementing these, we also will consider it as noncompliance with the resolution," Nebenzia said, Reuters reportedChina's envoy to Washington has urged the US to do more to resolve the nuclear crisis on the Korean Peninsula, while stressing that the UN resolution on Pyongyang also calls for dialogue and peace talks

    The ambassador's remarks followed shortly after the DPRK's latest missile launch drew condemnation from the United Nations and refueled fiery rhetoric about a military option from the Trump administration, which also asked China to mount pressure on the DPRK, partly by cutting oil shipments to Pyongyang"At the UN's headquarters in New York on Friday, Russia's UN Ambassador Vassily Nebenzia also called on the US and others to implement the "political and diplomatic solutions" that are called for in the latest sanctions resolution
