家里的口红堆了几百根，却还是少一只心仪的色号?

　　最近，巴黎欧莱雅推出了一款新的智能美妆产品——Perso，可以为消费者量身定制化妆品和护肤品，也许能帮你解决这个问题。

　　你想要的网红口红色号也能为你独家调至出来，拥有一个Perso相当于买了30支口红，李佳琦可能都要担心了。

　　With its focus on innovation and information, L'Oréal Technology Incubator is leading the rest of us into the future of beauty. Today, the Incubator unveiled its latest glimpse ahead — and cemented the importance of personalization — with the L'Oréal Perso.欧莱雅科技孵化器专注于创新和信息，正在引领我们其他人迈向美妆行业的未来。今天，科技孵化器与欧莱雅Perso一起揭开了Perso最新的面纱，并巩固了个性化的重要性。

　　This smart device creates custom formulas for lipstick, foundation, and skin care. Naturally, the experience starts with an app. First, the customer will take a photo of her face with the Perso app, which will use AI to identify skin conditions like dark spots, large pores, or wrinkles. Then, the app crunches location data to adjust for environmental concerns that affect skin, like pollution, pollen, and UV index. Perso作为一款智能设备可为口红、粉底和皮肤护理创建自定义配方。自然，体验始于应用程序。首先，客户要用Perso应用程序拍摄她的脸部照片，该应用程序将使用AI识别皮肤状况，例如黑斑、毛孔粗大或皱纹。然后，应用程序会处理位置数据，以适应影响皮肤的环境问题，例如污染、花粉和紫外线指数。

　　Finally, the user enters her own skin-care goals, like eradicating dark spots or dullness. The data is pulled into a custom formula; then, using its three-ingredient cartridges, the device will cook up your formulation and dispense it in a single-use dose. Essentially, the device predicts what your skin will need and creates it for you, no shuffling through your whole serum collection or Googling articles on how to protect your skin from pollution needed.最后，用户输入自己的护肤目标，例如消除黑斑或暗哑。数据被拉入自定义配方;然后，Perso将会配置一个含有三种原料的盒子，配置好您的配方并生成一次性使用的剂量。从本质上讲，Perso可以预测您的皮肤需求并为您创建解决方案，而无需在整个血清样本或有关如何保护皮肤免受所需污染的谷歌搜索文章中应接不暇地搜索。

　　"Perso will dispense a specific product using its three active ingredients," Guive Balooch, global vice president of L'Oréal Technology Incubator, tells Allure. "If it's very dry outside with high levels of pollution, you could increase the antioxidants and moisturizer. You can play with SPF. You can basically have something that's precisely made for you every morning."欧莱雅技术孵化器全球副总裁Guive Balooch告诉Allure：“Perso将使用其三种活性成分来配置特定产品。如果室外非常干燥且污染程度高，则可以增加抗氧化剂和保湿剂。可以与SPF搭配使用。基本上每天早晨您都可以用到适合自己的东西。”

　　The lipstick version will use three shade cartridges to create a customized liquid lip color — and you can use the Perso app to design the shade based on a trend, your outfit, or whatever color you’re hoping to match.口红版本将使用三个色彩底液盒来创建自定义的液体唇色-您可以使用Perso应用根据流行趋势、服装或希望匹配的任何颜色来设计色彩。

　　With its adjusting formulas, Perso makes it possible to have more control over your makeup and skin care — which Balooch says customers have asked for. "Consumers have been asking to be part of the process of their beauty and have a stronger relationship with how well it's working," says Balooch. "Here, you become part of the process of your cosmetic."凭借其可调整配方，Perso可以更好地控制你的化妆和皮肤护理。Balooch说，这是客户要求的。他表示：“消费者一直要求成为护肤美妆的一部分，并且与产品的表现之间有着更牢固的关系。在这里，用户就能成为美容过程的一部分。”

　　多知道一点

　　SPF

　　大家都知道要涂防晒来保护皮肤，那防晒霜上写的SPF50+都是代表什么?

　　SPF全称为sun protection factors，也就是日光防护系数。后面的系数是指紫外线照对皮肤的照射不致伤害的一个时间范围。

　　例如，SPF20可以防晒的时间为20*20=400分钟;SPF40可以防晒的时间为20*40=800分钟;SPF50可以防晒的时间为20*50=1000分钟。

　　不过，SPF并不是越高越好。SPF的数值越高，意味着物理或化学防晒剂越多，对皮肤的刺激更大，容易堵塞毛孔，滋生暗疮和粉刺。

　　所以一般室内活动，SPF15-20的防晒霜就够用了。
