敏感肌肤用什么护肤品？最近一直长痘痘

油敏+痘肌看过来！！！为了能更好的修复敏感肌，并成功战胜痘痘，本篇回答不会以草单的形式写！需要按照基础护肤的顺序来写。一些护肤习惯也会写上一点，希望能给各位油敏+痘肌参考。洗脸护肤的第一步！我们使用的各种清洁产品，主要目的是为了清洁粘附在皮肤表面的污垢。这些污垢能影响毛孔通畅，妨碍皮肤和粘膜正常生理功能的发挥。这些污垢主要分为：1 人体的生理性污垢（包括老化脱落的细胞、皮脂、汗液等）；2 外源性污垢（包括微生物、灰尘等环境污染物、各类化妆品药物残留等）；3 油痘皮还多一项任务。因为长痘，所以皮肤上还有鳞屑、脓液、痂等病理性污垢。看完上述文字，你是不是在想，哇，清洁好重要呀！是不是只要清洁做好了就不会长痘了？清洁不到位，确实会导致油皮长痘。但长痘的原因，并不是只有清洁不够这一种。说直白点，长痘的原因很复杂，清洁只是长痘原因中的冰山一角。而现在的问题是，有一部分油敏+痘肌的敏感，正来自于过度清洁。（如长期连续使用皂基、频繁洁面、爱用二次清洁水等）油敏肌建议使用氨基酸类的洁面产品，这类的成分温和不怎么招惹皮肤角质层里面的脂质和角蛋白，不容易破坏皮肤屏障，而且有一定“皂”的感觉（油皮就喜欢这个感觉）。需要注意的是，不是随便一个氨基酸洁面就适合敏感肌（比如大宝水凝保湿洁面乳、旁氏米粹洁面乳，正常皮肤用没事，但不适合敏感肌长期用）。油敏肌推荐珂润洁面泡泡、芙丽芳丝净润洗面霜、Elta MD氨基酸洁面（含香精）。洁面后：括弧，圈起来，这里是要考的！因为洁面可以带走皮肤中的保湿因子（帮皮肤储存水分的）。和洗脸方式无关，只要有大量的水，保湿因子就会被水带跑；还有清洁力强大的洁面产品有关，它能洗伤角质层，而角质层中存储着天然保湿因子。所以洁面后需要及时擦掉皮肤上水，并擦上保湿产品。特别是敏感肌要这样做，不然你就会发现，平时嫌皮肤出油多，这会儿皮肤的油一时半会儿不出来，贼干！咱油敏肌要是不愿意受这样的委屈，就赶紧擦保湿。保湿油敏+痘肌需要可不是一般的保湿！这里的保湿是指敏感肌最最最基础的护肤。因为皮肤屏障受损后，皮肤中的水分很容易流失，造成皮肤干燥起皮，也就是出现了所谓的外油内干。好了，我就不和大家绕圈子，直接讲重点！油敏+痘肌需要的“保湿”护肤品是：1 不含致痘成分如月桂酸，异硬脂酸异丙酯，肉豆蔻酸异丙酯 ，异十六醇，月桂醇聚醚-4。2 含有较少的封闭保湿的成分如矿油（白油）、凡士林、石蜡等最好不要有，封闭效果太好！3 含有舒缓抗炎的成分如七叶树苷、甘草酸二钾、红没药醇、积雪草提取物等。（因为皮肤屏障受损以后，皮肤容易受刺激，会不舒服啊什么的，抗炎成分能舒缓这些不适，让敏感皮也能舒爽一整天！）4 含有帮助修复皮肤屏障的成分修复细胞间脂质：神经酰胺1、3、6，胆固醇，脂肪酸（这三者需要以一定的比例和含量才能起到有效的作用。如果只是含有神经酰胺，那么它就是个普通的保湿产品，修复效果不咋地，含量过高还容易长闭口。同时，因为细胞间脂质是皮肤屏障中最难恢复的，所以修复屏障一般也是以补充这个为主）；加速角质细胞的新陈代谢：尿囊素等；修复皮脂膜，角鲨烷、甘油等（油皮最不操心修复的就是这个）。如玉泽皮肤屏障修复乳、CeraVe PM乳液（含有烟酰胺，不耐受可以考虑适乐肤的修复保湿润肤乳）、宝拉珍选岁月屏障透明质酸保湿精华液等。5 如果皮肤特别干燥紧绷，也可以用大喷来缓解不适。如理肤泉喷雾、雅漾喷雾、可丽安修复喷雾。注意使用次数太多，适量！一天不要超过5次，使用过多会给皮肤带来负担。6 为啥只推乳不推水或霜。水，用来即时补水还行，比如洁面后用一用，和喷雾的效果一样，保湿是很难保湿的，过一会皮肤还是干，保湿主要靠擦乳。如果要用就用舒缓类的，如雅漾舒润调理柔肤水、薇诺娜舒敏保湿润肤水、fancl修护补湿液等。霜，一般对油皮不太友好，质地厚重。当然了，如果乳液已经不够保湿了，爆皮了（刷酸爆皮也可用），还是阔以加个霜来抢救一下滴。如雅漾舒缓特护面霜、薇诺娜舒敏保湿修红霜、珂润保湿滋养面霜、理肤泉B5多效修复霜。这里就一个知识点，自己要学着根据皮肤状态灵活变通吖小可爱们！控油先说重点：一般来说，不建议敏感肌肤把护肤品用的太杂，堆积在脸上的成分越多，刺激敏感的可能性越大，但是油敏相较干敏比较难受的点就在于太油。油皮的油脂型毛孔粗大，通过控油也是可以缓解一二的。①物理控油 使用含有小孔隙的粉质，如淀粉、硅粉、豆粉，来吸附脸上的油脂。如欧丽提哑光控油保湿乳、贝德玛控油毛孔修复乳等。②从根源减少皮脂腺分泌油脂油敏+痘皮不得不面对的一件事就是，自己的脸上有两个极端，一个是“富”到流油，一个是干到爆皮，同时粉刺（是痘痘的亲爹，粉刺长出来了，距离发炎变痘痘就不远了）还能在这片看似干涸的沙漠上长！出！来！所以，我们可以控油，为屏障修复好后祛痘夯下坚实的基础。（控油+调理角质+消炎是祛痘的必备功课，你们看，前文已经把消炎列入了敏感肌的功课中，这里再加上控油，那么，我们距离干掉痘痘还会远吗？不，不会！）如：烟酰胺（控油、增强皮肤屏障、调理角质的新陈代谢，只要能耐受，这个是很推荐的成分），如olay小白瓶、前文的CeraVe PM乳液、奥乐芬B5保湿精华液等。抗氧化类（能抑制5a-还原酶的活性，减少皮肤出油，如VC、白藜芦醇、番茄红素、多酚类、核黄素等），如Arcona 白冰精华、Topix Replenix CF抗氧化精华（比白冰效果好）、AESOP 香芹籽精华、伊丽莎白雅顿橘灿精华（肤感略油）等。还有一个可尝试的成分，对自己的皮肤状态没点AC数的请跳过这部分内容！超低浓度的A醇（有祛痘、祛粉刺、抗衰老的作用，它是维A酸的衍生物，维A酸大家应该都很熟吧，祛痘的一线药物。维A醇的刺激性比维A酸低，如果浓度很低的情况下，敏感肌也可以适度尝试）如露得清维A醇晚霜、洛克ROC维A醇、ceraveA醇精华等。防晒护肤的最后一步，化妆的第一步！但，不建议油敏+痘肌化妆了，容易加重敏感，爆痘呢！防晒这个事，真的得做，还得认真做。为啥？就凭日光中的紫外线能加重炎症，导致敏感肌更敏感，痘肌痘痘更严重。①硬防晒，就是遮阳伞、帽子、口罩、树荫这些能有效遮蔽日光的防晒产品。只要能避免对皮肤的摩擦，这类防晒是对敏感肌最友好的。②防晒霜，首选物理防晒（成分表中的防晒剂以氧化锌和二氧化钛为主的这种），它们本身不招惹皮肤，氧化锌还能提供控油的作用，相较之下对油敏+痘皮友好。如雅漾日间隔离乳SPF30PA+++、NOVSPF32PA+++等。最后再说一个小tips：1 你以为的敏感肌可能不是你以为的敏感肌①首先是敏感肌和过敏容易傻傻分不清。敏感肌很容易过敏，因为皮肤屏障损坏了，更容易受到过敏源的刺激。但过敏和敏感真不是一件事儿。过敏是对某些特定的东西起反应（如泛红、起小疹子、瘙痒等），而敏感肌是很多东西都会让你起反应（如刺痛、泛红等）。②敏感肌还很容易和其它皮炎、湿疹还有玫瑰痤疮等皮肤病搞混。这类皮肤问题会损伤皮肤屏障，产生敏感肌。而且它们比敏感肌的问题要严重的多。如果你的脸有大面积持续性的泛红，或者起小疙瘩，这说明你得去看专业的皮肤科医生了，因为它有可能是别的更加严重的皮肤问题。2 敏感程度也分等级如果是偶尔泛红、刺痛、干燥、发热。这种情况可以考虑用护肤品来抢救一下。目前公认比较专业的肤质测试是鲍曼医生的16型，百度就能搜的到。严重的皮肤敏感，是一定要去医院看皮肤科的！！！这已经不是护肤品涂涂抹抹、清水洗脸、或者肌断食等能解决的问题了。它需要系统的治疗（如内服、外用药物、激光或光子嫩肤）。治疗周期也比较长，一般来说至少3个月。以上，祝好！祝各位油敏+痘肌早日恢复皮肤健康呀！如果还有其它护肤方面问题，也可以来找我聊聊天呀，看到你长得这么好看的份上，可以给你友情价！

无印良品洗面奶是皂基吗？这是很多人关心的问题。经过我的了解和研究，无印良品洗面奶是一款皂基洗面奶。

无印良品洗面奶的成分主要有椰油脂肪酸钠、油酸钠、棕榈酸钠等，都是皂基成分。这种成分能够有效清洁皮肤，去除皮肤表面的污垢和油脂，使皮肤清爽干净。同时，这种成分的洗面奶也具有一定的抗菌作用，可以有效地预防和减少粉刺和痘痘的产生。

除了皂基成分，无印良品洗面奶还添加了甘油等保湿成分，能够补充皮肤水分，使皮肤不会因为清洁过度而干燥。

温净洗面奶是一款非常不错的洗面奶，它是一款温和的洗面奶，不含皂基成分。它的成分主要有水、甘油、椰油酰胺丙基甜菜碱等。这种洗面奶能够温和地清洁皮肤，不会刺激皮肤，同时还能够保湿，使皮肤更加柔软细腻。

在使用洗面奶的时候，我们需要根据自己的皮肤类型选择适合自己的洗面奶。如果你的皮肤比较油腻，建议选择皂基洗面奶，能够更好地清洁皮肤。如果你的皮肤比较干燥，建议选择温和的洗面奶，能够更好地保湿皮肤。

总的来说，无印良品洗面奶是一款非常不错的洗面奶，能够有效地清洁皮肤，去除皮肤表面的污垢和油脂，同时还能够补充皮肤水分，使皮肤更加健康。如果你想要更加温和的洗面奶，温净洗面奶也是一款非常不错的选择。

最后，提醒大家，在选择洗面奶的时候一定要注意自己的皮肤类型，选择适合自己的洗面奶，才能够更好地保护皮肤。同时，也要注意洗面奶的使用方法，不要过度清洁皮肤，以免对皮肤造成过度刺激。
