What specific knowledge do you need to be a cosmetic consultant?

This is particularly difficult. There was an opportunity to be a cosmetic consultant, but I needed too much knowledge, so I didn't do it. To be a cosmetic consultant, you need to know all the cosmetic projects, and you can judge what kind of cosmetic projects the other party is suitable for according to the specific situation of the parties. Not only to dock customers, but also to dock hospitals. For example, the other person is a 50-year-old woman with a single eyelid and swollen eyes. How to recommend plastic surgery projects to each other, whether to bury the thread or cut it completely, the price, hospitals, experts and so on must be coordinated. I think you should take your time.
