的确很好用。我皮肤黄暗且干，偶尔会起小豆豆，用了大概5次了，肤色的确明亮了许多。开始敷上的时候皮肤会痛痛的，还担心是过敏了，其实是正常现象。另外关于贝佳斯批号的问题，可以参看一位美国淘宝卖家的说明。原文如下： 关于化妆品的生产日期问题：不少买家提出为什么收到的化妆品没有生产日期呢？原因很无奈，所有的进口化妆品都是没有标明生产日期的（专柜货的生产日期是进口到中国后再贴上的），只有批号，比如契尔式的批号无意义！！！ 引用契尔式公司关于批号的回信： Good morning, Hopefully this information will clear things up for you. The coding on the bottles is not an expiration or production date. They are references to batch logs our chemists keep with specific production details (raw ingredients, temperatures, bacterial content etc.) The codes are not sequential but are directly connected to the actual production history of that product. For instance, I'm looking at a Deodorant with a 7H code that was produced about 6-9 months ago. I also have a brand new Sunless Tanning Lotion which just shipped for the first time weeks ago and it has a 7C code. My Cryste Marine eye cream is about a month old and has a 7B code. Our products do not have expiration dates, per se. In general, they should be consumed within a certain amount of time once they have been opened and the safety seal removed. Everything in the line has a minimum of three year shelf life and most are considerably longer (years) than that unless they are kept in unusually high temperatures for an extended amount of time. Rest assured the items we are selling are well within their use dates. The 'rumor' of the codes being expiration dates has been going around for some time but is not factual. I hope this helps. 早上好 衷心希望这封信能够帮您澄清事实 瓶体上的代码并不是产品的生产日期,而是我们的化学家们用来标识产品细节的批号代码 --包括产品的原料,生产时的温度细菌含量等等 代码与产品的生产史密切相关, 而并非按顺序排列的 比如说:我们于6-9月前出产的DEODORANT批号为7H,而几周前开始其第一次运送的全新产品Sunless Tanning Lotion 批号为7C 同时, 一个月之前生产的Cryste Marine eye cream 批号为7B. 我们的产品就其本身而言并没有什么保质期,总的来说,一旦密封被打开,就应该在一定时间内将其用完.所有产品都有至少三年的销售期,实际上大多产品的寿命长过三年--除非它们长时间被放置于过高的温度下. 我们确定销售中的产品在其使用期之内..关于保质期的流言有时的确存在但并不真实,希望这对您能有所帮助。
