Identify the Skin Condition识别皮肤状况

It is helpful if you can initially identify a skin condition a consumer may be suffering from. This does not mean you can officially diagnose a consumer based on what you see—let’s leave that to dermatologists—but you should know enough about their appearance to understand what future product recommendations could look like for such a consumer. In making product recommendations, a cosmetologist must coordinate their choices with any recommendations the dermatologist makes.
若能初步识别消费者可能患有的皮肤状况将大有裨益。但这并不意味着你可以根据所见对消费者进行正式诊断——那应是皮肤科医生的工作——但你应当对其外观有足够的了解，以便理解未来针对此类消费者的产品推荐可能呈现何种形式。在提供建议时，美容师必须将其选择与皮肤科医生的建议相协调。

For instance, a customer comes in with visible redness and flaking on their face. While not diagnosing, you recognize these as possible signs of psoriasis. You check if they’ve been to a dermatologist, and yes, your hunch was correct: the customer reports that the dermatologist’s diagnosis is psoriasis. Moreover, the dermatologist advised the consumer to avoid harsh exfoliants or fragrances. So, you suggest gentle, hydrating products to be in step with the dermatologist’s advice.
例如，一位顾客面部有明显红肿和脱屑。虽然不是在诊断，但你认识到这些可能是银屑病的迹象。你询问他们是否看过皮肤科医生，答案是肯定的：顾客报告皮肤科医生的诊断是银屑病。此外，皮肤科医生建议消费者避免使用刺激性去角质产品或香料。因此，你建议使用温和保湿的产品，以与皮肤科医生的建议保持一致。

Next, you will have some practice identifying skin conditions from images. Prepare yourself as these images of skin conditions are not pleasant to look at, but there is a point to this.
接下来，你将进行一些从图像中识别皮肤状况的练习。请做好准备，因为这些皮肤状况的图像并不美观，但这是有目的的。
